Abstract
A master cylinder including a cylinder having one end open to the outside. A secondary piston guide ring, a sleeve and a primary piston guide ring are adapted to be fitted in this order into the cylinder from the one open end. A piston is slidably fitted in an axial direction of the cylinder, into each of the secondary piston guide ring, the sleeve and the primary piston guide ring. A retainer is provided at the open end of the cylinder, and adapted to abut against the primary piston guide ring so as to prevent escape of the primary piston guide ring from the cylinder. An elastic member is provided between a rearward end portion of the sleeve and a forward end portion of the primary piston guide ring.

A master cylinder comprising:
- a cylinder having one end open to the outside;
- a secondary piston guide ring, a sleeve and a primary piston guide ring adapted to be fitted in this order into said cylinder from said one open end;
- a piston slidably fitted in an axial direction of said cylinder, into each of said secondary piston ring, said sleeve and said primary piston guide ring;
- and
- a retaining member provided at said open end of said cylinder, and adapted to abut against said primary piston guide ring and prevent escape of said primary piston guide ring from said cylinder,
- wherein an elastic member is provided between a rearwardly facing surface of said sleeve and an opposing forwardly facing surface of said primary piston guide ring so that the rearwardly facing surface of said sleeve and the forwardly facing surface of said primary piston guide ring always abut each other through said elastic member without these surfaces making direct contact.
