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: A brake device for a vehicle includes: a brake pedal having a pedal portion and a lever portion that rotates about a rotation axis when the pedal portion is operated; a housing that rotatably supports the lever portion; and a plate member configured to generate a reaction force with respect to the lever portion in response to a stroke amount of the brake pedal. The plate member has a longitudinal surface defined by a side extending in a longitudinal direction of the plate member and a side extending in a width direction of the plate member. The longitudinal surface is arranged so as to face the lever portion. When the pedal portion is operated, the plate member is bent to generate the reaction force.

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.
