It can be easily installed in the water tank 20. Moreover, since the net-like cylinder member 43 is attached in the cooling water tank 20 without using a dedicated attachment part such as an attachment bracket, the number of parts can be reduced and the cost can be reduced.

  In the above-described embodiment, the locking protrusion 32 on the lower surface of the support plate portion 31 is locked to the upper end portion of the inner peripheral surface of the mesh tube member 43, but the present invention is not limited to this. Even if the locking projection 32 is locked to the upper end portion of the outer peripheral surface of the mesh tube member 43, the same effect can be obtained. Further, if the latching protrusion 32 is latched so as to be sandwiched from both sides of the upper end portion of the inner peripheral surface of the net-like cylindrical member 43 and the upper end portion of the outer peripheral surface facing this, it can be supported without using the binding band 33. It can be fixed to the plate portion 31.

  Further, in the above embodiment, the locking portion described in the claims is not limited to the locking protrusion 32, and the upper end portion of the net-like cylindrical member 43 can be inserted into the lower surface of the support plate portion 31. In this case, it is not possible to integrally fix the support plate portion 31 of the electrical component storage box 30 using the binding band 33 or the like. The upper end portion of the net-like cylindrical member 43 can be locked to the inner peripheral wall or the outer peripheral wall of the annular insertion groove to restrict horizontal movement.

  Moreover, in said embodiment, although the support plate as described in a claim is the support plate part 31 formed integrally with the electrical component storage box 30, this invention is not limited to this. The same effect can be obtained even with a support plate that is made of a member different from the electrical component housing box 30 and is constructed from one end of the peripheral edge of the upper end of the cooling water tank 20 to the other end.
