BRAKING OPERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/216337
Kind Code:
A1
Abstract:
[Problem] To provide a braking operation device capable of accurately detecting an operation of a brake pedal by means of a simple configuration. [Solution] The present invention is provided with: pushers 19, 20 connected to a brake pedal 2; a hydraulic mechanism 5 which is provided between the pushers 19, 20 and a pressing member 27, and transmits the thrust of the pushers 19, 20 to the pressing member 27 through hydraulic pressure; first elastic mechanisms 23a, 23b which generate an elastic force in a direction causing the pushers 19, 20 to be spaced apart from the pressing member 27; a cylinder 18 which accommodates the pushers 19, 20 and restricts retreating ends of the pushers 19,20 in the direction in which the pushers 19,20 are spaced apart from the pressing member 27; and a second elastic mechanism 37 which is provided at a position at which the cylinder 18 is pressed against the pressing member 27, and generates an elastic force that resists the elastic force which, in the first elastic mechanisms 23a, 23b, causes the pushers 19, 20 to be spaced apart from the pressing member 27.
