<p>PROBLEM TO BE SOLVED: To prevent breakage of a seal in installation of a reservoir so as to prevent the reservoir from coming off, provide high reliability, and improve workability in the installation. SOLUTION: The first engaging part 21 and the second engaging part 22 are arranged on a cylinder main body 18 side in a master cylinder 17, while on a reservoir case 23 side, the first locking projection 31 with high deformation strength and an elastically deformable second locking projection 32 are arranged, and an engaging groove 27 into which a hook in the second locking projection 32 is locked is arranged in the second engaging part 22. A hook 37 in the first locking projection 31 is locked in the hook 25 in the first engaging part 21, and at the same time, the hook 42 is locked in the engaging groove 27 in the second engaging part 22 so as to be prevented from coming off by means of a coming off preventing face 47 while the second locking projection 32 is elastically deformed.</p> |
