Secondly, also can set up the end that can keep rolling element in the ring structure of rolling element retainer of the present invention, when ring structure upset in conjunction with after make the end be positioned at the limit end of rolling element retainer, make remaining in the rolling element retainer that the rolling element of rolling element retainer limit end can be more suitable.
Moreover, the present invention again can be between involutory each other additional designs one through hole in the spacer, can make lubricant body by having good lubricating effect.And the space that the present invention designs this through hole simultaneously can moderately change, and can help that lubricant body is more smooth and easy to improve lubrication effect by through hole.
In addition, the present invention is in order to cooperate rolling element reflux cycle path shape, rolling element retainer after the upset combination can be designed to have a radian, and the radius of curvature of this radian is not less than the radius of curvature that rolling element refluxes, and makes the smooth and easy backflow of rolling element retainer energy.
The person is that ball or roller all can be applicable to rolling element retainer of the present invention regardless of rolling element again, and the shape that is designed to be consistent with rolling element because of its shape that only need change interval body gets final product.
The invention has the beneficial effects as follows: connecting band becomes a ring structure in succession with interval body, this ring structure upset keeps the space in conjunction with forming one, rolling element promptly places this maintenance space to roll, make the space of rolling element retainer that the elastic range of adjustment can be arranged, make the rolling element circulation of rolling smooth-goingly and reduce surface friction drag.
