Description of the Invention: [Technical Field] [0001] The present invention relates to a rolling body retaining chain and a linear motion mechanism thereof that can be used for torsion operation, in particular, the rolling element retaining chain will be axially The plurality of rolling bodies extending in a row are spaced apart from each other and held therein, and the rolling elements are subjected to torsional deformation to overcome the bending resistance when running in a circulation passage that is not perpendicular to the holding chain surface. [Prior Art] [0002] The current linear motion mechanism has a moving member and an axially extendable rail member, and the moving member and the rail member each provide at least one column corresponding to each other, and a row of rolling bodies and tracks between the rails Contacting and rolling on the track, the moving member provides a recirculating straight channel and two revolving channels for each column corresponding to each other, and the revolving channel is connected with the recirculating straight channel and the end face of the track to form a circulation channel, so that the rolling body can be The obstruction zone enters the return straight channel via the revolving channel, and enters the track zone from the return linear channel and then through the revolving channel. Therefore, the rolling body can circulate in the circulation channel, and the rolling member can be moved on the track member by rolling of the rolling body. Run along the track infinitely. [0003] In order to avoid collision between the two rolling elements, in US Pat. No. 5,927,858, a spacer block design is provided between the balls; and because the gap between the spacer block and the balls makes the spacer block easy to tilt, The offset, while interfering with the loop channel, prevents the smooth operation. [0004] In addition, in the U.S. Patent Nos. 5,974, 605 and 6, 5, 5, 571, etc., the ball connecting chain is disclosed. The ball connecting chain has two axially arranged elongated strips and the spacer blocks are connected in an axial arrangement, and the balls are placed. Between the block block 100114771 Form No. A0101 Page 4 / Total 22 pages 1002024739-0 201243182, and because the ball connecting chain is formed into a flat strip, the ball connecting chain can be vertical by the flexibility of the flat strip The flat surface formed by the two elongated strips, that is, the flat direction (hereinafter referred to as the ball joint chain surface) is curved without hindrance, but has a large rigidity in the vertical direction, and resistance is generated in the male-curved direction. This design is therefore only suitable for the circulation channel to be completely on the plane of the vertical ball joint chain surface and the ball link chain to bend in two dimensions; and when the circulation channel is not completely in this plane, the ball link chain must be inclined to the ball The connecting chain direction is curved, and the resistance to the vertical direction [the bending of the direction must be overcome. This design will therefore produce an impedance of 0 and the operation will not be smooth. [0005] 100114771 Therefore, the inventor of the present invention has proposed the "Rolling Chain" of the Republic of China Invention Patent No. 1273185 to solve the problem that the ball connecting chain is not smoothly operated during the twisting operation, and (4) the bead chain is arranged by more than one. The ball and the axially extending (four) lamella are formed; the spacer chain provides a plurality of front and rear dents in which the balls are located. The spacer chain comprises a plurality of spacer blocks arranged in front and rear, and the balls are separated by two balls between the spacer blocks; at least two elastic strips extending axially and elongated and elastically connecting the ends of the laterally extending elastic connecting strips are connected to the elastic bands, (4) The spacer block is elastically connected... and (4) connected (4) "Maximum length and sufficient elasticity, it can be more freely bent back and forth, left and right, and the spacer block can also be __f strips in various directions with respect to the splicing strip via elastic joints. It is possible to operate under the resistance of 彳M, in the German soil channel that changes direction in the third dimension. Form number A0101
