A guide mechanism includes a moving member supported by a supporting base frame and moving along a predetermined path with respect to the supporting base frame. A guide projection provided in the moving member is inserted in a guide groove provided in the supporting base frame and moves through the guide groove for guiding the moving member along the path. The guide groove is formed of a pair of thin wall members disposed with a predetermined space therebetween. When the guide projection is in the guide groove, a front end of the guide projection does not contact a bottom surface of the guide groove, and the guide projection slides in a state that a base surface of the guide projection linearly contacts edges of the thin wall members constituting the guide groove. |
