  • a long members like the frame section 18 is machined by, for example, cutting a stainless steel material, and therefore non-conductor coating becomes weak on end surfaces (cut surfaces), and the long member is likely to be corroded.
  • the first cutouts 41, the second cutouts 42, and the third cutouts 43 are formed in the lower horizontal parts 25 below the lower ends of the frame sections 18. Consequently, in portions where the first cutouts 41, the second cutouts 42 and the third cutouts 43 are formed, spaces are formed below the lower ends of the frame sections 18. Consequently, a part of water that reaches the lower ends of the frame sections 18 flows into these spaces (the first cutouts 41, the second cutouts 42, and the third cutouts 43), and does not stay in the lower ends of the frame sections 18. Accordingly, a flow rate of the water that stays in the lower ends of the frame sections 18 is reduced, and therefore it is possible to suppress occurrence of corrosion in the frame sections 18 and the lower horizontal parts 25.
  • the frame sections 18 are placed on the upper surfaces of the lower horizontal parts 25 of the frame 22, and therefore the lower horizontal parts 25 can receive load to the frame sections 18 input from the upper side. Consequently, it is possible to improve rigidity of the housing 7.

Consequently, when the load of the frame sections 18 is input from the upper side, the lower horizontal parts 25 can receive load input in the ends of the frame sections 18, on which stress is concentrated, and therefore it is possible to improve rigidity of the frame sections 18, and to further improve rigidity of the housing 7.

Components similar to those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
  • each lower horizontal part 25 of a frame 22 is formed in a substantially flat plate shape, and any cutouts and the like for allowing water to pass are not formed in the lower horizontal parts 25.
  • each frame section 45 is formed with a plurality of cutouts 46 at the lower end. More specifically, the frame section 45 has a lower edge formed in a corrugated shape. In the lower edge of the frame section 45, mountain portions of the corrugated shape are in contact with the lower horizontal part 25, valley portions of the corrugated shape become cutouts 46, and are separated from the lower horizontal parts 25. That is, the plurality of cutouts 46 are continuously formed in substantially the same shape at the lower end of the frame section 45.
  • the plurality of cutouts 46 are formed in a first plate section 31 and a second plate section 32 of the frame section 45.

  • cutouts are also formed at a lower edge of each frame supporting member 19.
  • the cutouts formed at the lower edge of each frame supporting member 19 are formed at such positions as to correspond to the cutouts formed in the frame sections 45. That is, in a case where the respective cutouts are formed at substantially the same position, and the frame section 45 and the frame supporting member 19 are disposed so as to be aligned, the cutouts are formed so as to penetrate horizontally.
  • the cutouts 46 are formed at the lower ends of the frame sections 45. Consequently, in portions where the cutouts 46 are formed, spaces are formed between the lower ends of the frame sections 45 and upper surfaces of the lower horizontal parts 25. Consequently, water that reaches the lower ends of the frame sections 45 passes through these spaces (cutouts 46), and does not stay in the lower ends of the frame sections 45. Accordingly, a flow rate of the water that stays in the lower ends of the frame sections 45 is reduced, and therefore it is possible to suppress occurrence of corrosion in the frame sections 45 and the lower horizontal parts 25.
  • the plurality of cutouts are formed, and therefore contact portions of the frame sections 45 and the lower horizontal parts 25 are increased. Consequently, when load is input to the frame sections 45 from the upper side, the load can be received by a large number of the contact portions in the lower horizontal parts 25. Accordingly, it is possible to suppress concentration of stress on the frame sections 45, and therefore it is possible to more suitably suppress deformation or the like of the frame sections 45, and to improve rigidity of the housing 7.
  • cutouts 46a formed at a lower end of each of frame sections 45a are each formed in a substantially rectangular shape, and the single large cutout 46a may be formed in each of a first plate section 31 and a second plate section 32. Any cutout is not formed in a connecting portion of the first plate section 31 and the second plate section 32 of each frame section 45a, and horizontal ends of the frame sections 45a.

Any cutout 46b is not formed at an end opposite to a connecting portion of lower edges of the first plate section 31 and the second plate section 32 too.
