ABSTRACT:
In a hydraulic pressure control valve for use with a master cylinder, a valve chamber is formed at an attaching section of a valve body. An annular recess is formed in the valve body at a location of an end of the stepped bore, which opens to the valve chamber. A valve element is arranged within the valve chamber for movement therewithin. The valve element has a stud which extends to an interior of the master cylinder and which receives, from the piston within the master cylinder, such a force as to cause the valve element to fall down. An annular preventing element is formed separately from the valve element and the valve body. The preventing element is arranged between the valve element and the end of the stepped bore, which opens to the valve chamber. The preventing element substantially covers an annular end of the annular recess, which opens to the valve chamber, for preventing a seal element from coming out of the recess, which is arranged therewithin.
