PROBLEM TO BE SOLVED: To smoothly allow thrust load and a radial load by combining synthetic resins having low sliding frictional resistance with each other, and prevent dust and the like from invading on a sliding surface. SOLUTION: A device is provided with a synthetic resin made lower case 20, a synthetic resin made upper case 30 which is assembled with the lower case 20, and a synthetic resin made thrust sliding bearing means 40 which is arranged between the upper case 20 and the lower case 30. In the upper case 30, a radial bearing part is formed between the inner circumferential surface of a cylindrical part 3a and the outer peripheral surface of the cylindrical part 22 of the lower case 20. The lower surface of an annular flange part 33 is faced to the cylindrical part 22 end surface of the lower case 20, and also an annular engaging hanging part 34 is elastically mounted on the annular engaging projection part 27 of the lower case 20 so as to assemble with the lower case 20. A thrust bearing means is arranged between surfaces where the annular recessed part 26 of the lower case 20 is faced and the annular wide width flange part 32 of the upper case 30 are faced to each other. |
