PROBLEM TO BE SOLVED: To support a shaft member without rattling by simple construction, without specially working the shaft member such as a guide shaft of a carriage. SOLUTION: The end 8b of a guide shaft 8 is inserted into the shaft hole part 36a of a plate-like frame 32, and a bearing bush 40 is fitted to the shaft end. At this time, the engaging pieces 49a, 49b of the bearing bush 40 are inserted inside the plate-like frame 32 through spread hole parts 36b, 7a. By rotating counterclockwise the bearing bush 40, the pressing piece 47 of the bearing bush 40 is pressed with the slope of a large contact hole part 36c, deformed inward in the radial direction, and the guide shaft 8 is pressure contacted with the shaft hole part 36a. |
