Abstract: A pedal-side rotating member is composed of a boss portion rotatably supported by a pedal shaft, a spring holding portion for holding one end of a return spring, a stopper arm being operatively in contact with an inner wall surface of a supporting body, and a mechanically-weaker portion, wherein the boss portion, the spring holding portion, the stopper arm and the mechanically-weaker portion are integrally formed as one unit. The spring holding portion is so configured as to be broken away from the boss portion at the mechanically-weaker portion, if an acting force larger than a predetermined value is applied to the stopper arm when the rotating member is rotated in a direction to an acceleration fully-closed position. A broken piece is held at a position inside of the supporting body, so that rotation of the boss portion is not adversely affected by the broken piece.

Abstract: A pedal spring urges a pedal spring receiving portion to rotate a manipulation member in an accelerator closing direction. The pedal spring has an end portion that contacts a first contact surface of a front segment. A hysteresis spring urges a hysteresis spring receiving portion, which is engaged with the manipulation member, in the accelerator closing direction. The hysteresis spring has an end portion that contacts a second contact surface of the front segment. A step surface is formed between the first contact surface and the second contact surface to limit movement of the end portion of the hysteresis spring.

Abstract: At a supporting member, an angle between an imaginary extension plane of an outer surface of a first partition wall and an imaginary extension plane of an upper surface of a pedal arm is one of an obtuse angle and a right angle. An angle between an imaginary extension plane of an outer surface of a third partition wall and an imaginary extension plane of a lower surface of the pedal arm is one of an obtuse angle and a right angle.

CPC classification number: G05G1/44 , Y10T74/20534
Abstract: A first coil spring urges a shaft in an accelerator closing direction. A support member has a space, in which a first center line of the first coil spring is convexly curved when the shaft is rotated in an accelerator opening direction. The first center line is straight or is convexly curved toward the space when the limiting portion contacts the support member.

Abstract: Each of a cross sectional shape of a contacting portion of a stopper arm and a cross sectional shape of an outer peripheral surface of a pedal shaft is formed in a circular shape, wherein a curvature radius is equal to each other. Each of a cross sectional shape of a stopper surface of a supporting body and a cross sectional shape of an inner peripheral surface of a bearing portion is formed in a circular shape, wherein a curvature radius is equal to each other. A distance between a center of a first virtual circle formed by the contacting portion and a center axis of the pedal shaft is made to be equal to a distance between a center of a second virtual circle formed by the stopper surface and a center axis of the bearing portion. An angle of the stopper arm with respect to the supporting body is not changed, even when the center axis of the pedal shaft is displaced with respect to center axis of the bearing portion.
Abstract translation: 止动臂的接触部分的横截面形状和踏板轴的外周面的横截面形状中的每一个形成为圆形，其中曲率半径彼此相等。 支撑体的止动面的截面形状和轴承部的内周面的截面形状各自形成为圆形，曲率半径相等。 使由接触部形成的第一虚拟圆的中心与踏板轴的中心轴之间的距离等于由止动面形成的第二虚拟圆的中心与中心轴之间的距离 轴承部分。 即使当踏板轴的中心轴线相对于轴承部分的中心轴线移位时，止动臂相对于支撑体的角度也不改变。

Abstract: A pedal device comprises a brake pedal, an accelerator pedal, a support member and an adjusting device. The brake pedal is operated to be depressed by a leg of a passenger, and an operation amount of a depressing operation of the brake pedal is transmitted as an electrical signal. The accelerator pedal is operated to be depressed by a leg of the passenger, and an operation amount of a depressing operation of the accelerator pedal is transmitted as an electrical signal. The support member is connected with the brake pedal and the accelerator pedal, respectively, to support the brake pedal and the accelerator pedal in a rotatable manner. The adjusting device adjusts a position or a posture of the pedal unit including the brake pedal, the accelerator pedal, and the support member.
