いる。2. Description of the Related Art Conventionally, a tripod type constant velocity joint (hereinafter, simply referred to as a "constant velocity joint" that allows angular displacement of both shafts and relative displacement in the axial direction while maintaining constant velocity between a drive shaft and a driven shaft). This constant velocity joint has a bottomed cylindrical shape with a shaft portion at one end and an opening at the other end,
An outer joint member having a plurality of guide grooves axially extending on its inner circumference, and an inner joint having a plurality of tripod shafts coaxially arranged inside the outer joint member and protruding into the guide grooves. And a spherical roller rotatably provided on each of the tripod shafts and rolling in the guide groove.

方向に沿って設けたものがある。This constant velocity joint is usually used by connecting the shaft portion of the outer joint member to the differential of an automobile. For example, in the case of a structure in which the shaft part of the outer joint member is connected to the mounting hole of the differential by serration coupling and is retained by a snap ring, etc., it is necessary to press-fit and remove the constant velocity joint when pressing it into or removing it from the differential. Tools are used. Therefore, there is one in which an engagement groove for engaging the press-fitting jig is provided on the outer circumference of the outer joint member along the circumferential direction.

る。There are roughly two methods for forming the engaging groove. The first method is, as shown in FIG. 6, an outer joint member 1
The entire material 1A of a is formed thick and the material 1
By cutting A, the engaging groove 18a is formed in the axially central portion of the outer peripheral portion. Then, in the second method, as shown in FIG. 7, the bottom portion 11b of the outer joint member 1b is formed thicker than the width of the engagement groove 18b, and the bottom portion 11b is formed.
The engaging groove 18b is formed on the outer periphery by cutting.

【発明が解決しようとする課題】ところが、上記第１の

低く、歩留りも悪いという不具合がある。さらに、外方
継手部材１ａは係合溝１８ａの両側部分が厚肉となるた
め、製品重量が重くなるという不具合もある。However, when the engaging groove 18a is formed by the first method described above, a large press machine is required at the time of forging due to the large cross-sectional area of the material 1A, and the cutting is performed at the time of cutting. Since the amount is large, there are problems that productivity is low and yield is low. Further, since the outer joint member 1a has thick portions on both sides of the engaging groove 18a, there is a problem that the product weight becomes heavy.

低下、異音や振動の発生の原因ともなる。On the other hand, when the engaging groove 18b is formed by the second method, the bottom portion 11b of the outer joint member 1b is thick, so that the weight of the product also becomes heavy. Further, if the bottom portion 11b of the outer joint member 1b is made thick, the distance between the joints is shortened because the constant velocity joint must be moved closer to the wheel side by that amount, so the joint angle accompanying the angular displacement is large. As a result, the life may be shortened and abnormal noise or vibration may be generated.

The object is to provide a constant velocity joint capable of forming.

An inner joint member having a plurality of tripod shafts that are coaxially arranged inside and protrude into the guide groove, and a spherical roller that is rotatably provided on each of the tripod shafts and that rolls in the guide groove. In the tripod type constant velocity joint, the outer joint member has a shallow bottom portion formed at the innermost portion of the guide groove so that the groove bottom surface becomes shallow, and the engaging portion is provided at a portion facing the shallow bottom portion. The structure is such that a mating groove is provided.

能となる。In the constant velocity joint according to the present invention, since the outer bottom of the guide groove of the outer joint member has the shallow bottom portion formed so that the groove bottom surface becomes shallow, the outer portion of the portion corresponding to this shallow bottom portion The wall thickness of the joint member increases. Therefore, by providing an engaging groove for engaging the press-fitting jig in the portion facing the shallow bottom, the engaging groove projects from the outer periphery of the outer joint member or the outer joint is formed to form the engaging groove. It is possible to provide the engaging groove having a sufficient depth and width without making the bottom portion of the member thick.
