Abstract
The object of the present invention is to exhibit the function of a throttle valve mechanism without making the whole of a master cylinder large-sized and to simplify the structure and to reduce the number of pieces of parts. In order to attain this object, the present invention has throttle valve mechanisms with a floating valve body which sits and throttles the flow of the hydraulic fluid to the reservoir from the pressure generating chambers when the pistons operate and which opens when the pistons do not operate, and the throttle valve mechanisms are arranged in the fluid passage for the supplementation of the hydraulic fluid, and the throttle valve mechanisms have a floating valve body with a throttle passage and a valve seat with and from which the floating valve body is brought into contact and is separated, and the valve seat is provided at the tip of the connecting portions to the cylinder body of the reservoir.
