BRAKE HYDRAULIC CONTROL UNIT

摘要

PROBLEM TO BE SOLVED: To provide a brake hydraulic control unit in which the pull-out of a cover member is prevented by partially caulking the opening portion of a cylinder hole. SOLUTION: In the cylinder hole 18 formed in a base block 11, a slidable piston 19 and a coil spring 20 for energizing the piston toward the bottom of the cylinder hole are stored and the cover member 21 for closing the opening portion of the cylinder hole is mounted. The opening portion of the cylinder hole is partially caulked along the outer periphery of the cover member to form a locking portion 29 which locks the cover member. COPYRIGHT: (C)2011,JPO&INPIT
