To provide an existing automatic voltage regulator for power distribution in which work for providing a protective plate to a viewing window through which a check of a tap position is greatly simplified.
A bolt pass-through hole 312a is formed at a window frame 312 so as to correspond to window frame mounting tap holes 310a which are formed at a window frame mounting seat 310. The window frame is mounted to the automatic voltage regulator for power distribution which is mounted with inserting bolts 314 through the bolt pass-through holes in a state that the bolts 314 are inserted through two protective plate support members 350a, 350b which have bolt pass-through holes 350a1, 350b1 and protective plate mounting tap holes 350a2, 350b2. A protective plate 340 is mounted that has a bolt pass-through hole 340a which is formed so as to correspond to one of the protective plate mounting tap holes and rotatable around the axis of a protective plate supporting bolt 315a inserted into the bolt pass-through hole, and has a slit 340b which is locked by a protective plate supporting bolt 315b which is screwed with the other protective plate mounting tap hole.
