摘要： A tripod type constant velocity joint comprises a housing having three track grooves which are defined at trisected positions of the housing along a circumferential direction and extend in a radial direction; a spider having three polyhedral trunnions which are projectedly formed at trisected positions of the spider along the circumferential direction to be respectively inserted into the track grooves and each of which has at least two polygonal surfaces; inner rollers a circumferential inner surface of each of which has a curved contour for surrounding the polyhedral trunnion; a plurality of needle rollers assembled to a circumferential outer surface of each inner roller; and outer rollers each formed to be rotated through the needle rollers, to be moved in an axial direction of the inner roller, and to be moved in an axial direction of the track groove along a guide surface of the housing.
