止め装置。[Scope of Claim for Utility Model Registration] A valve plunger of a valve mechanism that is slidably fitted into a valve body, and a valve plunger that is inserted from the outside in the radial direction into a hole formed in the valve body and engaged with the valve plunger. A retaining portion of a key member that prevents the plunger from being pulled out from the valve body; a circular arc portion of the key member that is integrally connected to the retaining portion and surrounds approximately half of the outer circumference of the valve body; Preventing the key member from coming out in a brake booster, which includes a retainer that surrounds approximately half of the outer periphery of the valve body and has both ends connected to each of the arcuate portions to prevent the key member from coming out of the hole. In the device, engaging recesses are formed inside both ends of the arcuate portion of the key member, and engagement recesses are formed outside both ends of the retainer due to the elasticity of the retainer, so that the key member and the retainer are connected to the valve body. an engaging pawl for preventing the retainer from being separated in the radial direction outward; and the key member to prevent the key member from coming off in the axial direction of the engagement between the engagement recess and the engagement pawl. Device.
