る回り止め締結装置。 A rotating shaft having a mounting shaft having a non-circular portion on its outer periphery and a male threaded portion having a screw on the outer periphery of the shaft end smaller than the mounting shaft by a step on the shaft end side, and the mounting shaft of the rotating shaft. A flat plate shape with a hole into which the driven member is fitted so as to come to a dead end on the back side away from the shaft end of the mounting shaft, and the driven member is fitted so as not to come into contact with the driven member and rotate toward the shaft end of the mounting shaft. A container-shaped lock washer that rises from the periphery of the bottom member toward the axial tip side of the rotating shaft and has a peripheral portion that can be deformed toward the side of the nut, and a lock washer that is screwed into the male thread of the male threaded portion of the rotating shaft. The nut is composed of a screw and a nut having an annular protrusion at the end that touches the periphery of the flat bottom member of the lock washer and a non-circular part on the outer periphery. The nut is screwed onto the end of the rotating shaft by inserting the lock washer into a non-circular portion of the outer periphery of the nut.
