Abstract: A valve timing adjustment device includes a sprocket, a vane rotor and a shim. The sprocket is configured to rotate. The vane rotor is received in the sprocket such that the vane rotor is rotatable relative to the sprocket. The vane rotor includes a supply oil passage that is configured to communicate with an external oil passage, and a rotational phase of the sprocket is changed when the vane rotor is rotated relative to the sprocket. The filter is configured to filter hydraulic oil, which is conducted in a connection oil passage that is configured to connect between the external oil passage and the supply oil passage. The shim is placed between the driven shaft and the filter.

Abstract: A tubular member is provided between an inner wall of a hole portion in a fixed member and a shaft. A predetermined gap is provided between an inner wall of the tubular member on a radial inside thereof and the shaft, so that the shaft is rotatable around an axis with respect to the tubular member. On the other hand, the inner wall of the hole portion and the tubular member are fixed to each other. When a load is applied to a predetermined position of a brake pedal, where a driver can apply a pedaling force in a stuck state in which the tubular member and the shaft are stuck together, a torque that releases fixation between the inner wall of the hole portion and the tubular member is greater than 0, and is smaller than a damaging torque that damages at least a part of the brake pedal device.

Abstract: A pedal device includes: a pedal configured to rotate about a rotational axis; and a reaction force generator configured to generate a reaction force corresponding to an urging force generated by pressing operation of the pedal. The pedal includes an urging portion configured to transmit the urging force to the reaction force generator when the urging portion is rotated integrally with the pedal. The reaction force generator includes a linearly moving portion configured to move linearly in an extending direction of a central axis of the reaction force generator when the pressing operation is performed. The urging portion has an urging surface configured to urge a contact surface of the linearly moving portion. The urging portion is placed at a position where a virtual urging center passes through a virtual axis perpendicular line when the pedal is rotated within a predetermined rotational range.

Abstract: At a pedal device, a force applied from a pedal at a time of rotating the pedal moves a first guide portion of a first holder to slide relative to a second guide portion of a second holder in a vehicle front-rear direction, resulting in deformation of a first resilient member. Furthermore, the force applied from the pedal at the time of rotating the pedal moves the second guide portion to slide relative to a third guide portion of a guide member in the vehicle front-rear direction, resulting in deformation of a second resilient member.

Abstract: A pedal device for a vehicle includes a pedal unit, a rubber member and a restricting member. The pedal unit is displaced by receiving a pedal operation from a driver of the vehicle. The rubber member is pressed by the pedal unit displaced in response to the pedal operation and generates a reaction force against a displacement of the pedal unit. The restricting member is configured to restrict the displacement of the pedal unit separately from the rubber member, when the rubber member generates the reaction force.

Abstract: A bushing member includes: a large diameter portion which is inserted on a radially inner side of a coiled segment of an assist spring and includes a straight portion which extends in an axial direction; and a small diameter portion which is located on a radially inner side of a housing and has an outer diameter that is smaller than an outer diameter of the large diameter portion. The coiled segment includes a contact portion that contacts the straight portion at a radially inner surface of the contact portion. In an axial direction, a location of an end of the straight portion, which is located on one axial side where a driven shaft is placed, coincides with a location of an end of the contact portion located on the one axial side, or is on the one axial side of the location of the end of the contact portion.

Abstract: A pedal device includes a pedal, a rotatable shaft, a cover and a housing main body. The rotatable shaft includes a first projection and a second projection. A first bearing rotatably supports the first projection. A second bearing rotatably supports the second projection. The pedal is supported by the rotatable shaft to enable rotation of the pedal relative to a housing. The cover and the housing main body are fixed relative to each other in an adjusted state where a position of the cover and a position of the housing main body are adjusted such that a radial position of a central axis of the first bearing and a radial position of a central axis of the second bearing coincide with each other.

Abstract: A housing is fixed to a vehicle. A shaft is rotatably mounted on the housing about a predetermined axis. A brake pedal is fixed to the shaft and operates around an axis of the shaft. A sensor device outputs a signal that detects a position of the shaft and the brake pedal relative to the housing, or a signal that detects a load applied to the brake pedal. A first fixing portion fixes a sensor component constituting at least a part of the sensor device to the housing or the brake pedal. A second fixing portion fixes the sensor component to the housing or the brake pedal using a fixing method different from that of the first fixing portion.

Abstract: An inductive sensor detects a position of a detection object relative to a fixed body, in which the detection object is either provided as (i) a rotating body rotatable about a predetermined axis relative to the fixed body or (ii) a movable body movable in accordance with movement of the rotating body. The inductive sensor includes a circuit board and multiple targets. The circuit board has, implemented thereon, a transceiver coil including a transmitter coil and a receiver coil, and a transceiver circuit that supplies a high frequency wave to the transmitter coil and outputs a signal corresponding to a change in inductance of the receiver coil, and is fixed to the fixed body. The multiple target objects are configured to move in synchronization with movement of the detection object and to include a conductor.
