Abstract
An object of the present invention is to provide a master cylinder which decreases the number of necessary parts, achieves easy assembly and stabilized quality, and surely prevents a float from coming off. In the present invention, the master cylinder tank 20 contains working fluid in the interior of a tank body 21 and incorporates a float 25 movable vertically in response to the increase and decrease in the working fluid by being guided by a float guide 22, and coming-off preventive portions 24, 24, capable of being deformed elastically, are provided to cover at least a part of the float 25 by extending a part of the float guide 22 upward beyond a guide rib 23. The coming-off preventive portions 24, 24 are formed by being bent to the inside into a shape such as to partially cover the float 25, so that the float 25 is prevented from coming off by the coming-off preventive portions 24, 24.
