Abstract: Positioning of a cover relative to a housing is made at two locations. i.e., fitting between a first intermediate shaft and a first recess and fitting between a second intermediate shaft and a second recess. In this way, a load of the cover is not conducted to an output shaft through a cover-side bearing. Therefore, in a state where the cover is fixed to the housing, an excessively large load is not generated between a cover-side bearing and the output shaft and a housing-side bearing and the output shaft.

Abstract: A turbocharger for an engine includes a compressor impeller, a turbine wheel, a turbine housing, a cover, and a flow passage switching valve. The impeller is for compression of intake air. The wheel drives the impeller. The housing includes first and second exhaust scrolls independently of each other, and a flow passage switching hole. The first and second exhaust scrolls swirl exhaust gas which is discharged from the engine and blow the swirled exhaust gas toward the wheel. The hole guides exhaust gas into the second exhaust scroll. The cover is provided separately from the housing. The valve opens or closes the hole, and includes a movable part having a rotatable shaft and a valving element. The movable part is attached to the cover. The cover is press-fitted to the housing, so that the valve is attached to the turbocharger.

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 brake device includes a brake pedal, a pedal operation detection section, a tank section, an actuator, a master cylinder, a brake fluid path and a reaction force generating section. The master cylinder includes a cylinder section that forms a storage chamber for storing brake fluid and a piston rod that connects to the brake pedal and pushes out the brake fluid stored in the storage chamber and discharges the brake fluid to an outside of the cylinder section by moving a distance corresponding to an amount of operation of the brake pedal. The brake fluid flow path guides the brake fluid discharged from the storage chamber by being pushed out by the piston rod to the tank section. The reaction force generating section includes an elastic member that generates a reaction force on the brake pedal by elastically deforming according to the amount of operation of the brake pedal.

Abstract: A pedal device includes a shaft, a pedal, a housing, a reaction force generating mechanism, and a connecting rod. The connecting rod includes an arm portion and a push portion. The arm portion is connected to a back surface of the pedal. The push portion is connected to the arm portion. The push portion is configured to transmit force from the pedal to the reaction force generating mechanism by contacting the reaction force generating mechanism when the pedal is stepped on by an operator. Further, the connecting rod is connected to the back surface of the pedal, to rotate with the pedal about the axis of the shaft when the operator steps on the pedal, while an angle defined between the back surface of the pedal and an axis of the connecting rod is maintained.

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 has an elastic member that generates a reaction force against a driver's pedaling force applied to the pedal pad. A first housing covers the reaction force generation mechanism, and an opening at least on one side. A second housing is provided on one side of the first housing in a swing direction of the pedal pad. Further, the first housing has a largest opening on a second housing side, which is closed by the second housing and into which the elastic member of the reaction force generation mechanism in a non-bending state is insertable.

Abstract: An accelerator device includes a pedal lever, a reaction force adjuster and a controller. The pedal lever operates according to a stepping operation. The reaction force adjuster is driven by an actuator, and is capable of adjusting a reaction force that is a force in a direction of pushing back the pedal lever. The controller includes a target operation amount setting unit and a drive control unit. The target operation amount setting unit sets a target operation amount, which is an operation amount of the pedal lever according to a vehicle speed. The drive control unit controls a drive of the actuator. The controller controls the reaction force according to the target operation amount so that the operation amount of the pedal lever is within a target range when switching from an automatic drive to a manual drive.

Abstract: An actuator includes an electric motor, an output shaft and an output lever. The output lever is fixed to one end portion of the output shaft, which is located at an outside of a housing. The output lever includes a cylindrical hole, through which a cylindrical portion of the output shaft is received, and a cutout, which is radially outwardly recessed from the cylindrical hole. A part of an inner wall surface of the cutout, which is connected to an inner wall surface of the cylindrical hole, is defined as a root corner. The root corner is shaped in a convex curved surface form in a view taken in an axial direction of the cylindrical hole.

Abstract: A rotation stop shape is visually recognizable through an exposing hole. A relative angle between an output shaft and an actuator lever can be freely set while the rotation stop shape, which is visually recognizable through the exposing hole, is used as the reference angle of the output shaft. Therefore, it is possible to limit disadvantageous variations in a fixation angle of the actuator lever. The fixation angle of the actuator lever relative to the output shaft can be freely changed by using the rotation stop shape, which is visually recognizable through the exposing hole, as a reference angle of the output shaft.
