Abstract
PURPOSE:To easily manufacture a low friction resistance bearing having a desired dimension accuracy with a molding by specifying the inner diameter of the bearing to support an optical system holding body freely turnably, slidably and movably to the shaft and providing a projection part for sliding and contacting. CONSTITUTION:A bearing 14 of an optical system holding body is supported by a supporting shaft 16 and an optical system holding body turns with the shaft 16 as a center freely and slides and moves freely along the shaft 16. The inner circumference of a bearing 16 is made into a large diameter from one edge to contact to the shaft 16 toward other edge and brought into contact with the shaft 16 by three sets of projecting stripe parts 14A-14C. By the taper constitution, simultaneously when the mold releasing characteristic at the time of molding is improved, it is not necessary to increase the dimension of respective parts and the low friction resistance bearing of a desired dimension accuracy is easily manufactured by the molding.
