Claims

[Scope of utility model registration request]

It is equipped with a shaft 5 that supports a door body 6, and a casing 1 having a shaft hole 7 through which both ends of the shaft 5 pass, and the shaft 5 is supported in the shaft hole 7 of the casing 1 through a bearing member. In the door shaft support structure, the bearing member 20 is attached to the peripheral edge 7 of the shaft hole 7 of the casing 1.
a leg portion 22 that protrudes from a toward the axial direction of the shaft 5; and a surface 24 that extends from the leg portion 22 from both ends along the outer circumference of the shaft 5 and comes into contact with the outer circumferential surface 5a of the shaft 5; A door shaft support structure comprising a plurality of support pieces 21 each having a support portion 23 formed with a curvature slightly smaller than the curvature of the outer peripheral surface 5a of the shaft 5.
