Claims

[Claim for Utility Model Registration] In a cover mounting structure in which a cover is removably attached to the rack body, the cover 6B is embedded in the circumferential surface 21 of the cover and can be operated from the circumferential surface. a rotating operation section 20a, a lock arm 22 that can be rotated in both directions by operating the rotation operation section, and a lock arm 22 that is fixed to the lock arm and fixed to the rack main body when the lock arm is rotated in one direction. A certain cam plate 17,
The cover mounting structure is provided with a lock mechanism 16 consisting of a lock pin that rides on and is locked on the cam plate 17a and is removed from the cam plate by rotation of the lock arm in the opposite direction.
