Contactedly moving guide shaft for bearing

Abstract

Abstract PURPOSE:To reduce the resistance value by providing a spiral groove on a guide shaft which guides a frame body so as to enable a linear reciprocating motion freely. CONSTITUTION:A round shaft 4' by which the linear guide of a frame body 1 is carried out is inserted into bearings 3 provided in the bearing parts 2 of the frame body 1. And, a spiral groove 5 is continuously formed on the external surface of the round shaft 4' along the overall length or nearly overall length. Thus, since the contacting surface between the round shaft 4' and the internal surface of the bearing 3 is lessened, the contact resistance is reduced.
