PURPOSE:To make a spare time larger in proportion to a grade whereby positive driving force transmittible, by installing both of a valve gear and a limiting passage in the within of a passage which interconnects an inlet connected to a braking force generating source with an outlet connected to a braking operation device. CONSTITUTION:A valve gear 1 is provided with a casing 3 which presents an appearance of a cuplike form making up a hole 2 on the bottom. At the bottom of this casing 3, an inlet member 4 taking on an almost T-shaped form in its section is closely fitted in, while at the opening part, an outlet member of the same form is as well closely fitted in. The inlet member 4 is provided with a piping connection part 16 in order to make contact with a brake master cylinder whose connection part is interconnected to the inside of a cylinder member 8 via a choke passage 17. |
