Since the configuration other than the use of the holding unit 22 is the same as that of the first embodiment, the same components are denoted by the same reference numerals and description thereof is omitted.

  The plate holding part 22 has a substantially rectangular plate-like main piece 22a having translucency, and a side piece 22e extending in a direction perpendicular to the main piece 22a is provided on the outer edge of the main piece 22a. Is provided. In addition, the side piece 22e on one end side along the width direction of the main piece 22a is integrally provided with an attachment portion 22b for attaching the plate holding portion 22 to the branch switch 4 along the width direction of the main piece 22a. In addition, shaft portions 22c and 22c projecting outward are provided at both ends of the attachment portion 22b along the width direction of the main piece 22a. Further, the side piece 22b provided with the mounting portion 22b is provided with protrusions 22d on both ends with the mounting portion 22b interposed therebetween. Here, the attaching means is constituted by the attaching portion 22b and the shaft portion 22c.

  On the other hand, on the front side of the branch switch 4, a pair of bearing portions 4 j, 4 j that fit the shaft portions 22 c, 22 c of the plate holding portion 22 and pivotally support the plate holding portion 22 near the edge on the input portion side. The plate holding portion 22 is rotatable between a closed position for holding the plate 14 as shown in FIG. 13A and an open position for changing the plate 14 as shown in FIG. 13B. Is pivotally supported. Further, as shown in FIG. 13C, in each bearing portion 4j in a state where the plate holding portion 22 is in the closed position, the rotation of the plate holding portion 22 is restricted to a portion corresponding to the protrusion 22d and held in the closed position. Protruding portions 4k are provided respectively. Here, the protrusion 22d of the plate holding part 22 and the protruding part 4k of the branch switch 4 constitute a rotation restricting means.

  Here, the plate 14 uses the plate 14 described in the first embodiment. For example, a projection (not shown) and a main piece 22a provided on two opposing side pieces 22e and 22e of the plate holding portion 22 are used. Is inserted and held between.

  In this distribution board A, by providing a projection 22d on the plate holding portion 22 and a projection 4k on the branch switch 4, the projection 22d is locked to the projection 4k in the closed position as shown in FIG. 3 (c). Thus, the rotation of the plate holding part 22 can be restricted and the plate holding part 22 can be held in the closed position. Therefore, after the distribution board A is installed, the plate holding portion 22 does not flutter due to vibration or the like, and it is possible to prevent the plate 14 from being detached from the plate holding portion 22 and lost. In particular, when the projection 22d and the protrusion 4k are provided on the attachment portion 22b side as shown in the present embodiment, the plate holding portion 22 and the branch switch 4 are first implemented on the side facing the attachment portion 22b. It is not necessary to provide the elastic locking piece 5d and the insertion hole 4e described in the embodiment. Further, in the state where it is out of the closed position, as shown in FIG. 13 (d), the projection 22d is not engaged with the protruding portion 4k, so that the plate holding portion 22 can be moved between the open position and the closed position. Can be opened and closed.
