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: A shaft outputs a thrust force in an axial direction by using a magnetic flux caused by an electric current flowing through a coil. A housing is made of resin and retains the shaft. The housing has a base portion having an outer circumferential surface, which is configured to be entirely in contact tightly with a sealing member. The housing further has a distal portion having an outer circumferential surface defining a depression. The outer circumferential surfaces of the base portion and the distal portion are substantially equal in diameter and are formed continuously.

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: A vehicle pedal module includes a brake pedal device and an accelerator pedal device. The brake pedal device has a brake pedal first housing configured to rotatably support a brake pedal rotating shaft and to cover a brake-pedal reaction force generation mechanism, and a brake pedal second housing configured to support an end portion of the brake-pedal reaction force generation mechanism opposite to the brake pedal. The brake pedal second housing extends from the brake pedal device to the accelerator pedal device, to have at least a part of the accelerator pedal device fixed thereto, and to be installed on a vehicle body.

Abstract: A flange part is formed in a shape whose diameter increases toward an outer diameter side of a center core. The flange part closes a space between an end of a magnetic delivery core on a second side in the axial direction and an end of the center core on the second side in the axial direction. An output member includes a contact part, which is brought into contact with an end of the center core on a first side in the axial direction when a plunger moves toward the second side in the axial direction. When the contact part is brought into contact with the end of the center core on the first side in the axial direction, the plunger defines an axial clearance between the plunger and the flange part.

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: In a brake pedal device, a brake pedal is connected to a casing with a posture changeable by a brake operation of a driver, and includes an operation unit that is pressed by a driver. A reaction force generating unit is provided inside the casing, and the reaction force generating unit is configured to generate a reaction force with respect to the brake pedal in accordance with an amount of change in the posture of the brake pedal during the brake operation, and to cause the brake pedal to return to a reference position when the brake operation is released. A sensor unit is provided outside the casing, to detect an amount of change in the posture of the brake pedal, and a sensor protector is provided at the casing in a position away from the brake pedal, to cover at least a part of the sensor unit.

Abstract: A brake pedal device includes a pedal pad rotatable about an axis when stepped on by a driver, and a reaction force generation mechanism generating a reaction force to the pedal pad according to a stepping amount of the pedal pad. The pedal pad includes a pedal base portion extending away from an axis side end to another end, and a pedal operation portion attached to the pedal base portion and stepped on by the driver. The pedal operation portion protrudes toward a pedal return side in a rotation direction about the axis with respect to the pedal base portion, and a surface of the pedal operation portion has a plane portion that is configured as a flat surface and is stepped on by the driver, so that the reaction force generated by the reaction force generation mechanism acts on the pedal pad in a direction piercing the plane 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.
