Abstract

The present invention provides a cover body and a switchboard capable of realizing an opening and closing mechanism of the opening and closing cover while reducing the number of parts. The cover main body (21) has an exposure window for exposing the circuit breaker in a state attached to the case. The first opening and closing cover (22) is held by the cover main body (21), and is rotatable between a closed position for covering the exposure window and an open position for exposing the exposure window. The first opening and closing cover (22) has a first rotation shaft (212) and a first bearing (221) capable of rotating around the first rotation shaft (212) while holding the first rotation shaft (212) one of the parties. A specific member composed of one of the case and the cover main body (21) has the other of the first rotation shaft (212) and the first bearing (221). A part of the first bearing (221) in the direction of rotation is provided with an open portion (2211). The first rotation shaft (212) is held by the first bearing (221) while being fitted into the first bearing (221) from the opening (2211) of the first bearing (221).

Description

technical field [0001] The present disclosure relates to a cover and a switchboard provided with the cover. More specifically, the present disclosure relates to a cover attached to a box and a switchboard provided with the cover. Background technique [0002] Conventionally, a distribution board for a house is known (for example, JPH11-155206 (hereinafter referred to as "document 1")). The switchboard described in Document 1 includes a box, a plurality of switches (circuit breakers) accommodated in the box, and an opening frame (cover) with a door screwed to the edge of the opening of the box. . [0003] In the switchboard described in Document 1, in order to realize the opening and closing mechanism of the door with respect to the opening frame, it is necessary to connect the opening frame and the door with other components such as hinges, and there is a problem that the number of components increases. Contents of the invention [0004] An object of the present disclos...
