Claims

[Scope of utility model registration request]

This is a bearing mounting structure in which a bearing 8 is externally fitted onto the free end side of a fixed shaft 6, and the fixed shaft 6 has a recess 33 in the middle thereof, and a recess 33 having approximately the same diameter as the inner circumferential surface of the bearing 8. A recessed groove 38 extending in the axial direction is formed on the outer periphery of the tip end on the free end side, while the recessed portion 33
A fixing part 41 whose movement in the axial direction is regulated by fitting into the fixing part 41, and a fixing part 41 extending from the fixing part 41 toward the distal end along the recessed groove 38, and an elastic member extending in the radial direction within the recessed groove 38. A bearing fixing member 40 having a deformable flexible portion 43 is provided, and furthermore, an axially intermediate portion of the flexible portion 43 is connected to the distal end portion located within the recessed groove 38 and further extends from the recessed groove 38. forming a position regulating portion 44 that protrudes radially outward;
The fitting position of the bearing 8 from the tip of the fixed shaft 6 is pressed by the inner peripheral surface of the bearing 8, and the recessed groove 3
When the flexible part 43 reaches a position beyond the position regulating part 44 buried in the bearing 8, the flexible part 43 returns the position regulating part 44 that contacts the corner of the tip side end surface of the bearing 8 radially outward. A bearing mounting structure characterized in that the movement of the bearing 8 toward the distal end side is restricted by the elastic return force of the bearing 8.
