  • Patent number: 9169867
    Abstract: A sleeve fits in a through-hole in a carriage to provide a return passage which makes sure of both the flexibility and the stiffness of the sleeve. The sleeve is constituted with fore and aft circular ends, a pair of columns and a pair of flexible columns lying lengthwise between the fore and aft circular ends to guide the roller, lengthwise slits lying between the flexible columns and the columns, and complementary ends made on the terminals of the fore and aft circular ends. The flexible columns have raised lands having curved outer surfaces, and recessions flanked by the raised lands and having rolling wall surfaces or the return passage. The raised lands and the recessions are arranged alternately in the lengthwise direction of the sleeve to give the sleeve the capability of elastic deformation.
