2. Description of the Related Art
Arranging a cage having a load portion and a no-load portion in the outer cylinder,
A ball is disposed between an outer cylinder and a retainer in an infinite ball circulation path formed by the load portion and the no-load portion, and is fitted on a shaft and slides linearly on the shaft. When the bearing member configured as described above is mounted in the inner hole of the housing, the bearing member having an outer cylinder formed with an outer diameter slightly larger than the inner diameter of the inner hole of the housing is pressed into the inner hole of the housing. The method of attaching and fixing the member in the inner hole of the housing,
There is a method in which a bearing member protrudes from an inner hole of a housing, and the protruding portion and the housing are attached and fixed by a fixing member.

However, in the above-mentioned press-fitting method in which the bearing member is press-fitted into the inner hole of the housing, the dimensional difference between the inner diameter of the inner hole of the housing and the outer diameter of the outer cylinder of the bearing member is formed with very high accuracy. If the dimensional difference is too large, press-fitting may not be possible, or if the dimensional difference is too small, fitting and fixing may not be possible.In addition, the specifications of the inner diameter of the inner hole of the housing may differ slightly. For example, it is necessary to form different outer cylinders having outer diameters corresponding to the inner diameter of the inner hole of each housing.

In a method of projecting a bearing member from an inner hole of a housing and fixing the projection to the housing with a fixing member, it is necessary to fix the fixing member to the housing with a screw or the like. It is necessary to form the attachment portion, and there are problems such as an increase in processing cost of the housing and a difficulty in mounting work for mounting and fixing the fixing member to the housing.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. When a bearing member is mounted and fixed in an inner hole of a housing, the bearing member is very accurately, simply, and securely attached to the housing. An object of the present invention is to provide a very practical bearing member that can be mounted and fixed and a method of mounting the bearing member.
