PURPOSE:To get a bearing device which is small-sized, cheap, and easy to be detached, by forming a guide groove on a supporting body, forming a circumferential member to which the bearing supporting part is fitted, on a bearing member, and constituting this bearing device as the bearing member is locked in the supporting body when the bearing member is rotated. CONSTITUTION:The top 11A of a shaft can be led into a guide groove 13A of a frame wall 13, along the direction of an arrow D. Next, an attaching part 11c is attached in a supporting groove 13B through a tapered part 11B, and a bearing member 11 is pushed along the direction of an arrow E, till the side face of an engaging part 11D of the member 11 abuts against the frame wall 13. Then, the bearing member 11 is rotated for an angle of 90 deg., to hold this member 11 as the frame wall 13 is kept between a projecting part 11F and an operating arm 11G, and moreover, a boss 11H is fitted in an engaging hole 13c, to hold the bearing member 11, and thrust of a shaft 2 is regulated by a ring member 14A.
