Abstract
The pedal device includes a pedal portion which the operator depresses, a pedal effort detecting portion being configured to detect the magnitude of the pedal effort in the depression direction when the operator depresses the pedal portion and being configured to output a signal corresponding to the magnitude of the pedal effort to the outside.
Claims16
A pedal device, comprising:
- a pedal portion which an operator depresses;
- and
- a pedal effort detecting portion being configured to detect magnitude of the pedal effort in the depression direction when the operator depresses the pedal portion and being configured to output a signal corresponding to the magnitude of the pedal effort to outside, wherein
- the pedal effort detecting portion includes a displacement amount sensor provided so as to detect the displacement amount of the pedal portion, and being configured to output a signal corresponding to the magnitude of the detected displacement amount, and a calculating unit configured to calculate the magnitude of the pedal effort based on the signal output from the displacement amount sensor, and
- the displacement amount sensor is a conductive member having elasticity, and is formed so as to be deformable when the operator depresses the pedal portion.
