Abstract: A plurality of reinforcing ribs, which extend from a cover-side bearing in an outer radial direction, is formed at a portion of a cover, at which a reaction force generated in response to operation of an electric actuator is applied. The reinforcing ribs can improve strength of the portion of the cover, at which the reaction force is applied. Therefore, it is possible to avoid a damage, such as deformation, a crack, at the resin cover caused by the reaction force applied to the cover.

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 that is depressed by a driver; and a reaction force generation mechanism. The reaction force generation mechanism generates a reaction force against a depression force applied from the driver to the pedal. The reaction force generation mechanism includes at least one resilient member, a first holder and a second holder. The first holder contacts the at least one resilient member from one side where the pedal is placed in one direction. The second holder contacts the at least one resilient member from another side that is opposite to the one side. One holder among the first holder and the second holder includes an outer guide portion, and another holder among the first holder and the second holder includes an inner guide portion that is fitted into the outer guide portion and is movable relative to the outer guide portion in the one direction.

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.
