Claims

[Scope of utility model registration request]

A remote control valve that switches and operates the hydraulic switching valve for controlling the hydraulic actuator of construction machinery is attached to a fixed plate of the machine body, a bracket is installed upright on the remote control valve, a pedal is rotatably supported on the bracket, and the pedal is depressed. When operating the pedal, which operates the remote control valve, a stable part is provided at the upper end of the bracket on which the foot rests when the pedal is depressed. The pedal is divided into two parts, formed into an integrated pedal with a dogleg shape when viewed from the side, and is attached so that the pedal can rotate in the front and rear direction relative to the bracket. Set it so that the stable part is located so that when you put your foot on the pedal, the front part of the sole of your foot is on the front tread part,
A pedal device for construction machinery, characterized in that the center part of the sole of the foot is in contact with a stable part of a bracket, and the rear part of the sole of the foot is in contact with a rear tread part.
