倍力装置。 A main body forming an internal space, a movable body movably inserted into the internal space to partition a negative pressure chamber and a variable pressure chamber, and a movable body slidably penetrating the main body from the variable pressure chamber side of the movable body. an input member extending from the outside of the main body to the negative pressure chamber; and an input member connected to the input member within the inner hole. a plunger that can move in response to an input from the inner hole and switch a valve device to selectively communicate the variable pressure chamber with the outside or the negative pressure chamber via the inner hole; A towing type booster comprising: an output member that receives a traction force from at least the movable body; a boot that covers the externally exposed portion of the cylindrical portion; and an opening provided in the boot that communicates the inner hole with the outside. In the device, a cylindrical part extending from the opening along the direction of movement of the output member and having an air circulation passage is integrally provided in the boot, and a cylinder with one end closed, into which the cylindrical part is fitted so as to move forward and backward. A tractable booster, comprising: a member, and a gap is formed between the cylindrical portion and the cylindrical member to communicate the atmospheric circulation passage with outside air.
