ABSTRACT:
Shifting prevention and sealing property between a boot for a constant velocity universal joint, having a thick portion on the inner peripheral surface of a large-diameter-side end portion and the outer peripheral surface of a tripod joint casing are enhanced, costs for preparing the casing are reduced, and the preparation is facilitated. One or a plurality of seal lips are disposed in the form of protrusions over the whole periphery in a peripheral direction of the inner peripheral surface of the large-diameter-side end portion of the boot for the tripod joint, into which the casing of the tripod joint is inserted, shift preventive walls are disposed on opposite sides of an axial direction via the seal lip, and inner diameters of the shift preventive walls are formed to be smaller than those of base portions of the seal lips. The shift preventive walls and the seal lips are disposed right under a band fastening portion.
