    摘要: An accelerator device includes a pedal pad and a strain gauge. When a driver of a vehicle having the accelerator device depresses the pedal pad, the pedal pad is deformed in a direction of a blank arrow. The strain gauge senses the displacement amount of the pedal pad in the direction of the blank arrow and outputs an electric signal, which corresponds to the displacement amount, to an outside as the depression amount of the accelerator device. When the driver removes a foot from the pedal pad, the pedal pad returns to a state of the pedal pad that is not depressed by the driver. Therefore, it is possible to limit occurrence of that the depression amount of the pedal pad becomes an unintended value due to, for example, catching of the pedal pad by a floor mat. As a result, the accelerator device can reliably sense the depression amount.

    摘要: A pedal operation amount detection apparatus comprising: a transmitting member that transmits a pedal operation force; a movement lever disposed so as to be movable with respect to the transmitting member; a sensor rod disposed so as to be connected to the transmitting member and the movement lever; and a deformable body that is disposed on the transmitting member and is deformed when the pedal operation force or a reaction force corresponding to the pedal operation force is transmitted from the movement lever to the deformable body, the pedal operation amount detection apparatus electrically detecting a pedal operation amount based on deformation of the deformable body, the sensor rod extending through both the movement lever and the deformable body, the pedal operation amount detection apparatus further comprising: a first locking portion provided at an end portion of the sensor rod on a side where the sensor rod protrudes from the deformable body; a second locking portion provided at an intermediate portion of the sensor rod between the deformable body and the movement lever; a first elastic member that is disposed between the second locking portion and the deformable body in a natural state or a compressed state when a pedal is not operated; and a second elastic member that is disposed to so as to be connected to the movement lever and the sensor rod, and urges the movement lever to cause the movement lever to contact the second locking portion, when the pedal is operated, a load in a direction to displace the sensor rod toward the first locking portion is applied from the movement lever to the second locking portion, the sensor rod being moved toward the first locking portion in a manner such that the first elastic member is elastically deformed between the second locking portion and the deformable body, and the deformable body being deformed.

    摘要: A floor support frame (8) is provided with a left side pilot valve (21). The left side pilot valve (21) is provided with a left side operating pedal (23) that is foot-operated. The left side operating pedal (23) is configured of a first foot board (26) that is mounted on the left pilot valve (21) to be rotatable in an upper-lower direction, a shaft (27) that is mounted in a rear portion of the first foot board (26), and a second foot board (28) that is mounted through the shaft (27) on the first foot board (26) to be rotatable in a horizontal direction. The second foot board (28) is rotatable between a storage position of overlapping the first foot board (26) and a use position of being rotated in the rear side of the first foot board (26). An operation regulating mechanism (29) is provided in the front side of the first foot board (26) to be engaged to the second foot board (28) when the second foot board (28) is rotated to the storage position to regulate a foot operation.
