    • A brake booster is disclosed. Specifically, an apparatus for preventing withdrawal of a key member, which is used to prevent the withdrawal of a valve plunger, forming a valve mechanism, from a valve body includes a retainer which prevents the withdrawal of the key member from the valve body. An insertion groove is formed in the valve body, and radially extending slits are formed in the end faces defined by the sides of the insertion groove. The retainer is formed with a locking portion, the free end of which is formed with an engaging portion, which is inserted into the slit to prevent an axial displacement of the free end of the locking portion. In this manner, the withdrawal of the key member from the valve is positively prevented.
