As shown in FIG. 5, the pressing portion 53 is pressed against the field edge 7 from below, so that the field edge 7 spreads the fitting piece 53a to both sides, and the fitting piece 53a is elastically deformed outwardly. When the fitting piece 53a recovers elastically, the fitting piece 53a is fitted into the groove 71 and the wiring board 5 is fixed to the field edge 7 as shown in FIG. Furthermore, since the tip end portions of the respective fitting pieces 53a are formed so as to be opened outward, the work of attaching the wiring board 5 to the field edge 7 can be easily performed. As shown in FIG. 1, the wiring board 5 is preferably provided with a screw hole 54 penetrating its thickness so as to be positioned below the field edge 7. As shown in FIG. 4, the work of fixing the wiring board 5 fixed to the field edge 7 by the portion 53 can be easily performed. However, even if the screw hole 54 is not provided, the wiring board 5 can be penetrated from below the field edge 7 and fixed with screws. Moreover, the shape of the fitting piece 53a can be suitably changed according to the shape of the groove part 71 of the field edge 7 to be used. Furthermore, in the present embodiment, the fitting portion 53 is formed only on one side, but it may be formed on the other side, and the place where it is formed can be appropriately changed according to the purpose.

  As shown in FIG. 1, a deflection preventing piece 52 is formed on the long side of the wiring board 5 so as to rise from both sides of the long side. Further, as shown in FIG. 7, the bending prevention piece 52 is arranged so that the bending prevention piece 52 is positioned between the two field edges 7 when the wiring board 5 is attached to the field edge 7.
