Problems solved by technology

[0004] However, in the above-mentioned slave hydraulic cylinder, the position of the seal that closes the slave hydraulic cylinder to prevent leakage of fluid inside the slave hydraulic cylinder is restricted by the protrusion provided on the piston or the cylinder main body, because the restricting member On the other hand, when the seal holding part is formed in a groove shape, air tends to accumulate in the seal holding part, and there is a tendency that a lot of man-hours are required for exhausting.

Embodiment Construction

[0066] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, directions such as front, rear, left, and right in the following description are the same as directions of a vehicle described below unless otherwise specified. In addition, an arrow FR indicating the front of the vehicle and an arrow UP indicating the upward direction of the vehicle are shown at appropriate locations in the drawings used in the following description.

[0067] figure 1The illustrated motorcycle 1 includes a so-called underbone type frame 2 . A pair of left and right front forks 5 , which pivotally support front wheels 4 , are pivotally supported on a steering stem 3 located at the front end of the vehicle frame 2 so as to be steerable via a steering shaft 6 . A steering handle 7 is attached to the upper portion of the steering shaft 6 .

[0068] A single main frame 8 extends obliquely downward from the steering stand pipe 3 , and a pair of...

Abstract

PROBLEM TO BE SOLVED: To facilitate discharge of air accumulated on the seal side of a control means, in a slave cylinder provided with a projected means for controlling a seal position on a cylinder body and a saddle riding type vehicle equipped therewith.SOLUTION: There is included a cylinder side seal (back seal 61) held on the radial inner side of the cylinder body 34, wherein the cylinder body 34 includes an inner projecting part 52 projecting to the radial inner side of the cylinder body 34 to control the position of the back seal 61. The inner projecting part 52 is formed with an air-vent passage 63 by cutting a portion of the inner projecting part to allow the air accumulated on the back seal 61 side to be discharged.

Description

technical field [0001] The present invention relates to a slave hydraulic cylinder and a saddle ride vehicle equipped with the slave hydraulic cylinder. Background technique [0002] Conventionally, there is known a brake system in which a master hydraulic cylinder is operated to generate hydraulic pressure by operating a brake operating member, and the slave hydraulic cylinder is operated by the hydraulic pressure, thereby causing a brake device to generate a braking force (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent No. 3533587 [0004] However, in the above-mentioned slave hydraulic cylinder, the position of the seal that closes the slave hydraulic cylinder to prevent leakage of fluid inside the slave hydraulic cylinder is restricted by the protrusion provided on the piston or the cylinder main body, because the restricting member On the other hand, when the seal holding portion is formed in a groove shape, air tends to accumula...
