    摘要: A boot for constant-velocity universal joint comprises a major-diameter cylindrical portion 2, a minor-diameter cylindrical portion 3 being separated away from and being put in place concentrically with the major-diameter cylinder portion 2, and having a smaller diameter than that of the major-diameter cylindrical portion 2, and an intermediate portion 10 connecting the major-diameter cylindrical portion 2 with the minor-diameter cylindrical portion 3. The intermediate portion 10 comprises a stretchable bellows portion 19 being connected with the minor-diameter cylindrical portion 3 integrally, and a rigidity-producing portion 11 being connected with the bellows portion 19 and the major-diameter cylindrical portion 2 integrally. The rigidity-producing portion 11 enlarges diametrically from the bellows portion 19 toward the major-diameter cylindrical portion 2, and additionally at least an outer peripheral surface 101 of the rigidity-producing portion 11 has a plurality of shoulders 61 in a stepwise manner. By means of the rigidity-producing portion 11, the rigidity at around the major-diameter cylindrical portion is enhanced, and thereby it is possible to suppress deformation at the time of assembling.

    摘要: A power transmission device is provided to improve sealing performance by reducing change in a surface pressure of sealing parts between power transmission shafts and boots. A first cylinder part of a boot is made from thermoplastic elastomer. A thickness Ta of the first cylinder part ranges from 1 mm to 2 mm, and a crimping allowance of the first cylinder part by a clamp member ranges from 0.1 mm to 0.5 mm. A width Wa of a first engaging groove formed at a power transmission shaft is equal to or greater than 20 percents of an axial width Wb of the clamp member. An axial distance from an end of the clamp member, near a bellows part, to an edge portion of the first engaging groove, near the bellows part, is in the range between 42.5 percents to 100 percents of the axial width Wb of the clamp member.

    摘要: A cross groove type constant velocity joint 10 comprises a cuplike outer race 11, an inner race 12, plural balls 13 and a cage 14. The outer race 11 has plural outer grooves 11a twisting about a rotational axis of the outer race 11 on its inner surface. The outer race 11 itself has plural restrictions 11b at the back of the outer grooves 11a to prevent the balls 13 from dropping out of the outer grooves 11a where the respective ball 13 is at the innermost end of the outer groove 11a.
