The workability at the time can be improved.

  In addition, in the electrical component box 30, a structure in which the weak electrical wire 54 is drawn into the electrical component box 30 is used separately from the strong electrical wire 53. Specifically, in the housing 31, a wire drawing hole 35 e for drawing the wire 54 is formed separately from the attachment member fixing member 42. Here, the electric wire drawing hole 35e is formed below the attachment member fixing member 42 of the front plate 35. And the electric wire 54 is drawn in to the housing | casing 31 by the electric wire drawing hole 35e.

  In such an electrical component box 30, a strong electric wire 53 such as a power supply line for power supply is drawn into the housing 31 via a conduit 55, and a weak electric wire 54 such as a communication signal line is directly connected to the housing. It can be pulled into the body 31. For this reason, when pulling an electric wire into the housing | casing 31, an electric wire can be drawn in to the housing | casing 31 appropriately according to the kind of electric wire.
