PROBLEM TO BE SOLVED: To enable the angle of an indicating instrument to be easily adjusted and the indicating instrument to be verified by providing the indicating instrument at a distribution panel body so that it is turnable freely in the vertical directions, and gear-locking a projection part which is provided inside the indicating instrument to the slit of the distribution panel body so that it can move freely. SOLUTION: A hole 2a for an indicating instrument is provided at a distribution panel body 2, and the lower periphery of the hole 2a for an indicating instrument is connected to the lower portion of a mounting plate 1a in that an indicating instrument 1 is mounted with a hinge 10, so that it is freely turntable in the vertical directions. Also, an annular projecting part 5 made of an iron plate is provided at the inner-surface side of the mounting plate 1a, and the projecting part 5 is inserted into a slit 2b that is provided at the upper portion of the hole 2a for an indicating instrument. Then, a packing 6 is provided at the inner peripheral side of the slit 2b, and the projecting part 5 is gear-locked at an arbitrary position by the packing 6. Since the projecting part 5 of the mounting plate 1a is gear-locked by the slit 6 and is gear-locked at an arbitrary rotary position in the vertical directions, so that the mounting angle of the indicating instrument 1 is easily seen by a monitoring personnel can monitor easily. |
