Abstract
An organ-type pedal device includes a housing, a shaft, a pedal pad, and a sensor unit. The housing is attached to a vehicle body. The shaft is rotatably supported around a center of a shaft receiving portion provided in the housing as a rotation axis. The pedal pad is fixed to the shaft and rotates about a same rotation axis as the shaft. The pedal pad has a structure in which a portion to be stepped on by a driver is arranged above the rotation axis in a vertical direction when being mounted on the vehicle. The sensor unit has a rotating portion provided at the shaft and a signal output portion provided at the housing for outputting a signal corresponding to a phase of the rotating portion, and detects a rotation angle of the pedal pad and the shaft.

A pedal device, configured to transmit an electric signal corresponding to an amount of a pedal operation by a driver to an electronic control device of a vehicle, the pedal device comprising:
- a housing attached to a vehicle body;
- a shaft rotatably supported around a center of a shaft receiving portion provided in the housing as a rotation axis;
- a pedal pad rotatable around a same rotation axis as the shaft, wherein a stepped portion of the pedal pad that is stepped on by the driver is positioned above in a vertical direction relative to the rotation axis when being mounted on the vehicle;
- and
- a sensor unit including a rotating portion provided at the shaft, and a signal output portion provided at the housing to output a signal corresponding to a position of the rotating portion, wherein
- the sensor unit is configured to detect a rotation angle of the pedal pad and the shaft;
- and
- a base plate provided on a surface of the housing opposite to the pedal pad, to be fixed to the vehicle body, wherein
- the base plate is made of a material having higher strength than the housing.
A pedal device, configured to transmit an electric signal corresponding to an amount of a pedal operation by a driver to an electronic control device of a vehicle, the pedal device comprising:
- a housing attached to a vehicle body;
