CAGE AND METHOD OF ASSEMBLING CAGE

摘要

Each pipe member has a plurality of slits located at intervals in the circumferential direction of the pipe member, extending in the axial direction of the pipe member, and extending through the pipe member in the radial direction of the pipe member. The pipe members are passed through through-holes of the first annular member and through-holes of the second annular member aligned with the through-holes of the first annular member. After shaft portions of rivets are passed through the pipe members, opposite end portions of each rivet are swaged to compress the pipe member in its axial direction to expand the pipe member in its radial direction. Thus, the pipe members are pressed to the inner peripheral faces that define the through-holes of the first and second annular members.

主权项

1. A cage comprising:
a first annular member made of resin, having a plurality of through-holes that are located at intervals in a circumferential direction of the first annular member, and having one-side axial end face located on one side in an axial direction of the first annular member; a second annular member made of resin, having a plurality of through-holes that are located at intervals in a circumferential direction of the second annular member, and having the other-side axial end face that is located on the other side in the axial direction and that contacts the one-side axial end face of the first annular member; pipe members each being a single-piece member, and each having a pipe portion that has a plurality of slits that are located at intervals in a circumferential direction of the pipe member, the slits extending in an axial direction of the pipe member and the slits extending through the pipe portion in a radial direction of the pipe member, and the pipe portions being passed through the through-holes of the first annular member and the through-holes of the second annular member; and fixed members each having a shaft portion passed through any one of the pipe members in the axial direction of the pipe member, a first fixed portion that contacts one axial end portion of the pipe member and that is fixed to one-side axial end face of the second annular member, and a second fixed portion that contacts the other axial end portion of the pipe member and that is fixed to the other-side axial end face of the first annular member, wherein an outer face of each of the pipe members is engaged with both an inner peripheral face that defines a corresponding one of the through-holes of the first annular member and an inner peripheral face that defines a corresponding one of the through-holes of the second annular member, with a frictional force.
