PROBLEM TO BE SOLVED: To provide a shield cover switchgear and a vessel in which a simple drive unit can be used, and the drive unit can be so disposed as not to be restricted to an opening periphery.SOLUTION: A shield cover switchgear comprises: a hinge member 4 which is connected to a vessel 10 and rotatably supports a shield cover 3; a first link member 11 connected to a back face of the shield cover 3; a second link member 12 rotatably connected to the first link member 11; a third link member 13 rotatably connected to the second link member 12; a support member 5 which is connected to the vessel 10 and rotatably supports the third link member 13; and traction means 6 which can tow a first end 13a on the side proximate to a side face 10a of the third link member 13 or a second end 13b on the side separated from the side face 10a. The shield cover switch gear is so configured that the shield cover 3 is made in a closed state by towing the first end 13a with the traction means 6, and made in an open state by towing the second end 13b with the traction means 6. |
