Claims

[Scope of utility model registration request]

An outer ring having three track grooves spaced at equal intervals in the circumferential direction formed on the inner circumferential surface and a circumferential groove formed on the outer circumferential surface, and a block housed within the outer ring and movable along the track grooves of the outer ring. A tripod type constant velocity universal joint configured with a trunnion kit including an elliptical roller and a trunnion kit, which has an opening corresponding to the track groove of the outer ring and which engages with the circumferential groove of the outer ring at the outer edge. A retainer is disposed on the end surface side of the outer ring, the retainer having a cover portion that is opposite to the outer ring, and a pair of stoppers facing each other with a distance smaller than the diameter of the spherical roller across the opening; A slip-off prevention device for a tripod type constant velocity universal joint fixed to the retainer outer ring by elastically engaging the covering portion with a circumferential groove of the outer ring and tightening the covering portion with a boot band from above via a boot.
