Patent ID: 8376867

Claim:
A sliding type tripod constant velocity joint comprising: an outer ring of a tubular form having three raceway grooves which are formed on an inner peripheral surface and which extend in a direction of a rotation axis of the outer ring; a tripod including a boss part connected to a shaft and three tripod shaft parts which are provided upright so as to extend outward in a radial direction of the boss part from an outer peripheral surface of the boss part and which are inserted into the raceway grooves, respective; an intermediate member which is provided on an outer periphery of a corresponding one of the tripod shaft parts so as to be oscillated relative to the corresponding one of the tripod shaft parts and which has power transmission surfaces on outer surfaces and opposing the side surfaces of a corresponding one of the raceway grooves; a plurality of rolling elements provided between the side surfaces of the corresponding one of the raceway grooves and the power transmission surfaces so as to roll along the side surfaces of the corresponding one of the raceway grooves; and a cage that supports the rolling elements such that the rolling elements circulate on an outer periphery of the intermediate member, wherein under a state where a rotation axis of the outer ring coincides with a rotation axis of the shaft, a central axis of the corresponding one of the tripod shaft parts is closer to an opening side of the outer ring than to a central part of a width of the power transmission surfaces in the direction of the rotation axis of the outer ring.
