<P>PROBLEM TO BE SOLVED: To allow a grounding switch installed at a rear surface side of a box body to be reliably operated from a front surface side, and further to facilitate assembly adjustment work thereof. <P>SOLUTION: A metal-enclosed type switch gear comprises: a grounding switch 11 installed at a rear surface side of a box body 1; a positioning mechanism that determines a racked-in position and a racked-out position of the grounding switch 11 while being directly coupled to a blade 12 of the grounding switch 11; and a first operation shaft 13 that has an operation port 14 for performing rack-in/rack-out operation disposed at a front surface side while being coupled to the positioning mechanism. The positioning mechanism is constituted of: a main shaft to which the blade is fixed; and a pair of stopper bases for blocking rotation of the main shaft at the racked-in position and the racked-out position. <P>COPYRIGHT: (C)2013,JPO&INPIT |
