Abstract
A guiding structure for a moving member includes a cam groove provided in a fixed member, a shaft inserted into the cam groove and attached to a moving member, and a collar provided on the shaft to be rotated around the shaft while slidably contacting groove walls of the cam groove. Thus, without applying a lubricant to the shaft and the cam groove, the shaft can be guided with less frictional resistance with respect to the cam groove.
Claims11
A guiding structure comprising:
- a fixed member and a moving member slidably attached to the fixed member,
- a cam groove provided in the fixed member and having groove walls and groove edges,
- a shaft attached to the moving member and inserted into the cam groove, and
- a collar provided on the shaft to be rotatable around the shaft while slidably contacting the groove walls of the cam groove, said collar having a flange formed on an outer periphery thereof to project radially outwardly from the outer periphery and to contact one of the groove edges of the cam groove.

A guiding structure comprising:
- a fixed member, and a moving member slidably attached to the fixed member,
- a cam groove provided in the fixed member and having groove walls,
- a shaft attached to the moving member and inserted into the cam groove, said shaft having an annular projection formed on an outer periphery thereof to surround the same, and
- a cylindrical collar provided on the shaft to be rotatable around the shaft while slidably contacting the groove walls of the cam groove, said collar having a hole for allowing the shaft to pass therethrough, an annular dent portion formed on an inner periphery of the hole for receiving the annular projection therein so that the collar is rotatably held around the shaft, and a length greater than a width of the cam groove to project outwardly from the cam groove.
