PROBLEM TO BE SOLVED: To provide an interlocking braking device which enables a master cylinder connected with a hydraulic type wheel brake to operate in accordance with braking operation of an independent braking operating element and interlocking braking operating element, and exerts braking operation force to the master cylinder and a mechanical type wheel brake during braking operation of the interlocking braking operation element, wherein a knocker for pushing a piston of the master cylinder is composed of a small number of parts and has a simple construction. SOLUTION: The knoker 25 of a single part which comes into direct contact with a rear end of a piston rod 31a is supported by a cylinder body 30 such that the knoker 25 can rotate around an axis perpendicularly crossing with one plane including an operating axis of a piston 31.
