Abstract: In a valve drive apparatus, which drives a first valve and a second valve of a supercharger, a first rod is rotatably connected to a first valve lever shaft at one end part thereof to drive the first valve and is connected to a shaft at the other end part thereof, and a second rod is rotatably connected to a second valve lever shaft at one end part thereof to drive the second valve and is connected to a second member at the other end part thereof. A spring is placed between a first engaging part of the first member and a second engaging part of the second member and urges the first member and the second member to urge a first contact part of the first member and a second contact part of the second member toward each other.

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: 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.

Abstract: A pedal pad includes a plate part having a plate shape. When a driver performs a depression operation on a plate part from one side in a plate thickness direction, the pedal pad rotates about an axis perpendicular to an extending direction of the plate part. A shaft member is provided at a position away and downward in a vehicle from the plate part. A housing rotatably supports the shaft member. A connecting portion connects the pedal pad and the shaft member. Such a pedal device is an organ-type pedal device in which a pedal lower end is positioned below in the vehicle than a pedal upper end when the plate part is not subject to the depression operation by the driver in the non-depressed state. The pedal device is provided with a gap between the housing and the pedal lower end.

Abstract: A pedal device to be pedaled by a user includes: a pedal supported to be swingable about an axis and to swing toward one side in a circumferential direction about the axis when being pedaled by the user; a housing; a reaction force generation portion disposed in the housing and to apply a force to the pedal toward another side in the circumferential direction; and a stopper. The stopper is arranged outside the housing, to swing about the axis together with the pedal while being supported by the pedal, and to stop the pedal by coming into contact with the housing in a non-pedaled state in which the pedal is not pedaled by the user.

Abstract: A pedal pad in an organ-type pedal device swings about a predetermined axis when stepped on by a driver's foot. A sensor unit outputs a signal corresponding to a swing angle of the pedal pad. A reaction force generation mechanism generates a reaction force against a driver's stepping force applied to the pedal pad. A first housing holds or covers at least one of a rotation shaft provided at the axis of the swinging of the pedal pad, the sensor unit, and the reaction force generation mechanism. A second housing is made of a rigid portion having a Young's modulus greater than that of the first housing or has the rigid portion at least in part. The second housing is configured to support a portion of the reaction force generation mechanism on one side opposite to the pedal pad by the rigid portion.

Abstract: An organ-type pedal device includes a housing attached to a vehicle body. A pedal pad of the pedal device is provided rotatably about a predetermined rotation axis with respect to the housing, and a stepped portion of the pedal pad is arranged above the rotation axis in a vertical direction of the vehicle. The pedal pad rotates in a forward direction in accordance with an increase of a pedaling force of the driver, and rotates in a backward direction in accordance with a decrease of the pedaling force of the driver. A sensor unit outputs an electric signal corresponding to a rotation angle of the pedal pad. A full-close stopper comes in contact with a lower part of the pedal pad with respect to the rotation axis, and prevents the pedal pad from rotating in the backward direction when the pedaling force of the driver is not applied thereto.

Abstract: A pedal pad includes a plate portion having a plate shape extending in a pedal extending direction and having a thickness in a plate thickness direction, and the pedal pad is rotatably movable about a pedal shaft center that is perpendicular to the pedal extending direction by a step-on operation of a driver to the plate portion from one side in the plate thickness direction. The plate portion has one end portion in the pedal extending direction positioned lower in the vehicle than an another end portion in the pedal extending direction in a non-stepping state in which the driver is not performing the step-on operation on the pedal pad. Furthermore, the one end portion of the plate shape of the plate portion extends in the pedal extending direction, more than a position of the pedal shaft.
