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. a cylindrical portion extending to the outside; an inner hole provided through the cylindrical portion; 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 and extending from the input member within the inner hole. a plunger that can move in response to an input and switch a valve device to selectively communicate the variable pressure chamber with the outside or the negative pressure chamber via the inner hole; and a plunger that is fitted to the outer end of the inner hole. and at least an output member that receives a traction force from 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 traction type booster, the opening of the boot is covered by a folded part formed integrally with the boot.
