To provide a fixing structure of a shaft capable of providing increased durability and reliability, reducing man-hours of machining and assembly, and reducing the number of part items to lower a cost by avoiding the formation of a rattling (clearance) radially between the rotating shaft side and the bearing side to prevent a relative movement radially between the rotating shaft side and the bearing side from occurring so as to prevent such defects as an uneven wear of a contact part between the rotating shaft and the bearing, damage to rotating shaft fixed members such as a retaining plate and bolts, and defective tooth bearing of gears.
In this fixing structure of the shaft so formed that the shaft end part of the rotating shaft is supported by bearings installed in a casing, and the rotating shaft is fixed to the inner rings of the bearings by a shaft fixing means. The shaft end face of the rotating shaft is disposed in a position moved to the inside by a specified amount from the outer side surface of the inner ring of the bearing, the bolts are screwed into the screw parts of the rotating shaft. The outer peripheral side face presses the outer side face of the inner ring of the bearing on the outer peripheral side face of the retaining plate formed so as to be allowed to come into contact with the outer side face of the inner ring of the bearing. By this pressing, the rotating shaft is fixed to the inner ring of the bearing with the spring action of the retaining plate.
