A cylindrical portion 11 for rotatably supporting the is formed. Two elastic pieces 3 are integrally formed on both sides of the tubular portion 11 so as to project parallel to each other in one direction and then bend in opposite directions to linearly project beyond the center of the tubular portion 11. Has been done.
The bent portions of these elastic pieces 3 are used as grips 9 for gripping the elastic pieces 3 and deforming them so that the tip end portions are expanded. An engaging claw 7 that is an engaging portion is formed at the lower end of the elastic piece 3. And the shaft protruding from the tubular portion 11
A retaining ring 12 is attached to the member 10.

等の効果を有する。Effect of the Invention As described above, according to the present invention, a bearing having a tubular portion that rotatably supports both ends of the platen is formed of an elastic material, and is parallel to each other in one direction on both sides of the tubular portion of the bearing. Two elastic pieces that protrude and then bend in opposite directions and linearly project beyond the center of the cylindrical portion are formed, and notches for fitting the cylindrical portion of the bearing to the side plates facing each other are formed. In addition, projecting guide portions having linear portions located on both sides of these notches so as to slidably surface-join and guide the elastic piece over a predetermined length are formed. By forming an engaging portion that elastically engages the facing portion and the guide portion with each other and bringing them closer to each other, the elastic pieces are deformed in a direction of separating the facing engaging portions of the elastic pieces from each other. Make the knob by the bent part of the elastic piece Since it is formed, when the tubular portion of the bearing is fitted in the notch of the side plate, the engaging portion between the elastic piece and the guide portion is engaged to prevent the stopper from coming off. Since the elastic piece is surface-bonded, the bearing can be prevented from tilting, and the grip portion can be easily disengaged from the engaging portion. In order to form the elastic piece, it is possible to increase the elastic piece's resilience by forming bent portions that project parallel to each other in one direction and then bend in opposite directions. This has the effect of improving the bearing assembly work.
