Abstract:
A wiper device includes: a pivot shaft that rotates back and forth within a predetermined angular range; an arm head that is fixed to the pivot shaft; a cover that is mounted to the arm head; and a wiper arm that is pivotally supported on the arm head to come into and out of contact with a surface to be wiped. The wiper arm includes an engagement concave portion that extends in a longitudinal direction of the wiper arm at a side portion in a pivot direction of the wiper arm. The cover includes an engagement convex portion that extends in the longitudinal direction of the wiper arm. Relative movement of the wiper arm and the cover is restricted by engagement between an engagement wall portion of the engagement concave portion and the engagement convex portion.
Abstract:
Disclosed is a wiper lever assembly that includes upper and lower levers, a plurality of pivotal connecting parts that are pivotally coupled to a longitudinal end of the upper lever, and a plurality of mating pivotal connecting parts that are disposed on the lower lever. The assembly further includes an upper pressing arc portion disposed on the upper lever over the plurality of pivotal pressing parts. The upper pressing arc is in slidable contact with a lower engaging arc portion disposed on the lower lever. In addition, a radius of curvature of a concave arc of the upper pressing arc portion and the lower engaging arc portion is larger than that of a convex arc of the upper pressing arc portion and the lower engaging arc portion.
Abstract:
A rotor having an axial direction includes at least a pair of rotor cores arranged in the axial direction, and a field magnet located between the rotor cores and magnetized in the axial direction. Each of the rotor cores includes a plurality of claw poles extending in the axial direction. Each of the rotor cores includes a magnetic flux controlling section, which appropriately causes a magnetic flux to flow to the claw poles.
Abstract:
A joint device includes a drive rotor fixed to a drive shaft, a driven rotor fixed to a driven shaft, and a ring-shaped buffer located between the drive rotor and the driven rotor. The drive rotor includes a drive engagement portion that projects toward the driven rotor in an axial direction. The driven rotor includes a driven engagement portion that projects toward the drive rotor in the axial direction. The buffer includes an outer surface, which includes a first engagement recess and a second engagement recess that are recessed toward a radially inner side. An outer diameter of a bottom surface of the second engagement recess is smaller than an inner diameter of the driven engagement portion or an outer diameter of a bottom surface of the first engagement recess is smaller than an inner diameter of the drive engagement portion.
Abstract:
There is provided an armature including a shaft; a core attached to the shaft; a commutator that is attached to the shaft, and includes a plurality of commutator segments; windings that are wound onto the core, and are connected to the respective commutator segments; and a short-circuit member that connects together a pair out of the plurality of commutator segments, and is disposed further to the commutator radial direction outside than an outer peripheral portion of the commutator.
Abstract:
A radial bearing is received in and is fixed to a bearing receiving portion of a yoke housing, which includes large and small diameter parts, to rotatably support a rotatable shaft. A thrust ball and a thrust plate are received in the bearing receiving portion on an axial side of the radial bearing, which is opposite from the rotatable shaft. The large diameter part receives and holds the radial bearing. The small diameter part holds the thrust ball. The thrust plate is held by an axial end area of the small diameter part.
Abstract:
An armature provided with: plural core configuration members that configure an armature core and are segmented from each other on progression along the circumferential direction of the armature core; plural insulators that each include plural insulating portions mounted to the core configuration members and a coupling portion that couples the plural insulating portions together; plural windings that respectively include plural winding portions, wound on the core configuration members with the insulating portions interposed between the winding portions and the core configuration members, and a crossing wire that connects the plural winding portions together; a fitting portion that couples together adjacent core configuration members out of the plural core configuration members; and an exposing portion that is formed to the plural insulators and exposes the fitting portion when viewed along the axial direction of the armature core.
Abstract:
A motor includes a rotor and a stator. The rotor includes a first rotor core including a plurality of first claw-like magnetic poles, a second rotor core including a plurality of second claw-like magnetic poles, and a magnetic field magnet arranged between the first and second rotor cores. The first and second claw-like magnetic poles are alternately arranged in a circumferential direction. The magnetic field magnet causes the first and second claw-like magnetic poles to function as magnetic poles different from each other. The stator includes a first stator core including a plurality of first claw-like magnetic poles, a second stator core including a plurality of second claw-like magnetic poles, and a coil section arranged between the first and second stator cores. The stator is configured to cause the first and second claw-like magnetic poles of the stator to function as magnetic poles different from each other and switch polarities of the magnetic poles on the basis of energization to the coil section. At least ones of the claw-like magnetic poles of the rotor and the claw-like magnetic poles of the stator are formed in a shape in which circumferential centers of distal end portions are shifted in the circumferential direction with respect to circumferential centers of proximal end portions.
Abstract:
An on-board optical sensor cleaning device includes an on-board camera and a discharge port. The on-board camera is mounted on a vehicle. The on-board camera includes a lens. The discharge port discharges fluid toward the lens. The discharged fluid removes foreign material collected on the lens. The lens and the discharge port are relatively movable. At least one of the lens and the discharge port is movable between a cleaning position, where the discharge port is located proximal to an image capturing range center of the on-board camera, and a non-cleaning position, where the discharge port is located farther from the image capturing range center than the cleaning position.
Abstract:
In a vehicle wiper device, a retaining portion is formed inside an arm piece at respective areas of a base end side fixing section, a main body, and a leading end side fixing section of the arm piece. A hose is retained by the retaining portion. This thereby enables the hose to be retained to the arm piece without using a retaining member, such as a holder, to retain the hose to the arm piece. Moreover, disposing the hose inside the arm piece enables the hose to be suppressed from being exposed or projecting out from the arm piece. The hose can accordingly be retained in the arm piece without having a detrimental effect on the appearance and while suppressing an increase in cost of the vehicle wiper device.
