Prevent shedding. In the latter manufacturing method, the method of arranging rolling elements on the roller inner peripheral surface in a series is called a keystone method without using an adhesive, and also in this case, when the roller is fitted together with the rolling elements on the leg shaft of the tripod member. The flange of the roller prevents the rolling element from falling off. In such a manufacturing method, since the roller and the rolling element are integrated and assembled to the leg shaft at the same time, the workability of assembling the tripod member is improved.

The roller 7 uses a pair of washers 8b to prevent the rolling element from falling off, so there is no effect of reducing the number of components described above. However, the flat washer 8b simply projects from the inner peripheral surface of the cylinder of the roller 7. Since an inexpensive material having a simple shape such as that described above can be used, the production cost of the tripod member can be reduced.
