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: An accelerator pedal is urged in an accelerator closing direction by a hysteresis spring and a return spring. A first increase rate is obtained by dividing an urging force of the hysteresis spring exerted in an accelerator-full-opening position of the accelerator pedal by the urging force of the hysteresis spring exerted in an accelerator-full-closing position of the accelerator pedal. A second increase rate is obtained by dividing an urging force of the return spring exerted in the accelerator-full-opening position of the accelerator pedal by the urging force of the return spring exerted in the accelerator-full-closing position of the accelerator pedal. The second increase rate is smaller than the first increase rate.

Abstract: When a rotational angle of a pedal is in a range from an angle of zero degrees to a predetermined rotational angle, which is larger than a full-opening-time rotational angle, a first Hall IC outputs a first voltage, which is twice larger than a second voltage outputted from a second Hall IC. When the rotational angle of the pedal is larger than the predetermined angle, the first Hall IC outputs a predetermined constant voltage. When an output difference, which is computed based on the first voltage and the second voltage, is equal to or smaller than a second threshold value, an abnormality of the sensed rotational angle of the pedal is determined.

Abstract: An accelerator device includes a first cover that provides an internal space for housing a return spring and a failure region where the first cover engages a second cover. The failure region has a thickness configured to be thinner than a thickness of a body of the first cover. When a pedal rotates to open an accelerator, a second cover side friction member creates a force that pushes the second cover toward an outside of the device. The force is relayed to a contact portion of the first cover via a contact portion of the second cover and causes a failure of the failure region. As a result, the return spring is prevented from falling out of the internal space when the body breaks.
