転軸の軸受構造。[Claims for Utility Model Registration] (1) The rotating shaft is supported in a machine box via two ball bearings, the outer ring of one bearing is loosely connected to the machine box, and the side surface of the outer ring is connected to the ball on the other side by a spring. While pressing toward the bearing, the outer ring of the ball bearing on the other side is supported immobile in the axial direction by the machine case, and movement is only allowed in the axial direction between the outer ring of the one bearing and the machine case. A rotating shaft bearing structure with intervening locking means. (2) The locking means that allows movement only in the axial direction between the outer ring of one of the bearings and the machine case is composed of a long hole in the axial direction and a locking pin provided between the outer ring and the machine case. A bearing structure for a rotating shaft according to claim 1 of the utility model registration. (3) In practical use, the locking means that allows movement only in the axial direction between the outer ring of one of the bearings and the machine case is composed of an axial hole and a key provided between the outer ring and the machine case. A bearing structure for a rotating shaft according to claim 1 of patent registration.
