Claims

[Scope of utility model registration request]

A power distribution board in which a unit is housed in a unit chamber in a drawable manner includes a pair of guide rails protruding from the bottom of the unit chamber in a longitudinal direction and guiding movement of the unit in the longitudinal direction; and a pair of guide rails. A regulating recess for regulating the amount of movement formed in one of the rails and having a length corresponding to the moving distance between the connection position and the test position of the unit, and one of the pair of guide rails. a first engagement recess formed at a position corresponding to one of the front and rear ends of the restriction recess, and a first engagement recess formed at a position corresponding to one of the front and rear ends of the restriction recess; a second engagement recess formed at a position corresponding to the other of the two, an operating shaft rotatably provided on the unit side so as to be located between the pair of guide rails, and this operating shaft. A switchboard unit comprising: an engaging member that is screwed into a threaded portion formed in the control shaft and that engages the regulating recess, the first engaging recess, and the second engaging recess by rotation of the operating shaft; Drawer device.
