Inventor: KIM TAE HWAN
IPC: B60T11/16
Filed: 2001-12-20
Abstract: PURPOSE: A master cylinder is provided to prevent a support member and a return spring from removing a resilient spring by improving a structure of the support member and a piston. CONSTITUTION: A step portion(32) is arranged to a guide portion(31) extended vertically to an axial direction of a second piston(30) to stick to a second combining hole(91). Therein, a second support member(90) is arranged to be inserted to the second combining hole to the guide portion and prevented from removing from the second piston though shock is transmitted from the outside. An extended portion(94) is extended from the second support member to the axial direction of the second piston. Thereby, combining force of the second support member to the second piston is increased because the extended portion contacts the step portion. The extended portion is formed around a circumference of the second support member. A second spring support portion(92) extended to a second resilient spring has a first support portion(92a) of the inside and a second support portion(92b) of the outside. A connecting portion(92c) is formed between first and second support portions. An outer diameter of the first support portion is larger than an inner diameter of the second resilient spring. An outer diameter of the second resilient spring is smaller than an inner diameter of the second resilient spring. Thereby, the second resilient spring is combined easily to the second support member with the second support portion and fixed firmly to the second support member with the first support portion. Consequently, the second support member and the second resilient spring are combined to the second piston firmly though outer impact is transmitted from the outside.
