グ。 Fig. 1 is a sectional view taken along a plane perpendicular to the axis of the shaft, showing the main parts of a tripod type constant velocity joint; Fig. 2 is a front view of the groove member as seen in the 2-2 line direction of Fig. 1; Figure 3 is a perspective view of the groove member, Figure 4 is a perspective view of the needle bearing, Figure 5 is a side view of the tripod type constant velocity joint, partially cut away along the axis of the shaft, and Figure 6 is the conventional A sectional view similar to Fig. 1 showing the main parts of the tripod type constant velocity joint, Figs. 7 and 8 a and b show the movement of the roller and the force applied to the roller when rotating at an angle. The schematic diagram, FIG. 9, is a graph showing the correlation between the rotation angle and the forcing force. 20: Shaft, 22: Roller, 24: Casing, 26: Groove member, 28: Tripod shaft, 32

Claims

[Scope of utility model registration request]

a shaft having three tripod shafts extending in the radial direction from portions equally spaced in the circumferential direction;
A roller having a spherical outer circumferential surface and rotatably supported by each of the tripod shafts, and a casing surrounding the shaft and having three grooves for inserting the tripod shafts and the rollers and extending in the axial direction of the shaft. a casing having equal intervals in the circumferential direction; and a groove member disposed between each of the two wall surfaces of each groove of the casing and the roller, the axis of the shaft and the axis of the tripod shaft. a groove member having a roller groove on a surface facing the roller, the roller groove being cut by the pitch circle radius of the roller and having an arcuate cross section, each wall surface of each groove member and each groove; A tripod-type constant velocity joint, including a needle bearing placed between the
