The second through hole 61 is formed in the inclined flat plate portion 62 of the rear peripheral wall portion 25C that extends in a direction that intersects the surface of the housing 14 in a state other than orthogonal to the surface.
That is, the reference vertical flat plate portion 52 is formed so as to extend from the rear side along the rear side (lower base 27) of the end surface plate 24 so as to form a plate surface perpendicular to the plate surface of the end surface plate 24. The inclined flat plate portion 62 is formed by cutting and raising the reference vertical flat plate portion 52 so as to extend obliquely with respect to the plate surface of the reference vertical flat plate portion 52.

As shown in FIG. 5, the first through hole 51 is formed so that the center line of the hole is orthogonal to the plate surface of the reference vertical flat plate portion 52, and the second through hole 61 is inclined at the center line of the hole. It is formed so as to be orthogonal to the plate surface of the flat plate portion 62. For example, the upper inclined flat plate portion 62 is formed to extend upward in a direction away from the housing 14, and an angle α formed by the plate surface of the upper inclined flat plate portion 62 and the plate surface of the reference vertical flat plate portion 52 is 25. Formed at °.
Therefore, as shown in FIG. 2, the angle formed by the center line of the course thread 16 that passes through the second through hole 61 formed in the upper inclined flat plate portion 62 and is fastened to the housing 14 and the surface of the housing 14. Is 65 °, and the course thread 16 is fastened to the housing 14 so as to be in an intersecting state other than orthogonal to the surface of the housing 14.

An angle β formed with the plate surface of 52 is formed at 45 °.
Therefore, as shown in FIG. 2, the center line of the course thread 16 that passes through the second through hole 61 formed in the lower inclined flat plate portion 62 and is fastened to the housing 14 and the surface of the housing 14 are formed. The angle is 45 °, and the course thread 16 is fastened to the housing 14 so as to be in an intersecting state other than orthogonal to the surface of the housing 14.
On the other hand, the angle formed by the center line of the coach screw 15 that passes through the first through hole 51 formed in the reference vertical flat plate portion 52 and is fastened to the housing 14 and the surface of the housing 14 is 95 °, and the coach screw 15 Is fastened to the housing 14 so as to be orthogonal to the surface of the housing 14.

  More specifically, on the upper side near the center between the upper and lower sides of the rear peripheral wall 25C of the bracket 22, a second penetration for penetrating the course thread 16 for attaching the rear peripheral wall 25C to the housing 14 is provided. An upper cut-and-raised piece functioning as the inclined flat plate portion 62 in which the hole 61 is formed is provided, and the rear peripheral wall portion 25C is a casing on the lower side near the center between the upper and lower portions of the rear peripheral wall portion 25C of the bracket 22. A lower cut-and-raised piece that functions as an inclined flat plate portion 62 in which a second through-hole 61 for allowing the coarse thread 16 to be attached to the through-hole 16 is formed is provided. In addition, a first screw for penetrating the coach screw 15 for attaching the rear peripheral wall portion 25C to the housing 14 at a plurality of positions spaced at predetermined intervals along the vertical direction of the rear peripheral wall portion 25C of the bracket 22. Through-holes 51 are formed.

As described above, as the first screw that is fastened to the housing 14 so that the rear peripheral wall 25C of the bracket 22 that functions as an attachment portion to the housing 14 in the case 2 is orthogonal to the surface of the housing 14. And a coarse thread 16 as a second screw fastened to the housing 14 so as to be in an intersecting state other than orthogonal to the surface of the housing 14.
That is, the first screw is passed through the first through hole 51 formed in advance in the attachment portion to the housing 14 to fasten the first screw to the housing 14 and is formed in advance in the attachment portion to the housing 14. The case 2 is attached to the housing 14 by passing the second screw through the formed second through hole 61 and fastening the second screw to the housing 14, and the case 2 is attached to the housing 14. Can be easily and easily performed.
Here, the first screw attached in a state orthogonal to the surface of the housing 14 is superior in the pull-out strength to the shear strength, and is attached to the surface of the housing 14 in a direction other than orthogonal. The screw No. 2 is superior in the shear strength than the pull-out strength. Further, the pull-out strength of the first screw is greater than the pull-out strength of the second screw, and the shear strength of the second screw is more than the shear strength of the first screw. It is preferable that the strength is large.
The term “perpendicular to the surface of the casing 14” is not only strictly meant, but also for the manner of mounting the first screw, the formation error of the first through hole 51, or the like, or for draining water that has entered the hole. The first screw is intentionally fastened slightly downward so that the pull-out strength can be effectively exhibited in use even if the first screw is not strictly perpendicular to the surface of the housing 14. What is necessary is just to consider it as orthogonal substantially.
Further, “other than perpendicular to the surface of the housing 14” means that the mounting angle of the second screw is a difference angle that cannot be regarded as orthogonal so that the shear resistance strength can be effectively exhibited in use. In particular, the mounting angle of the second screw is considerably different from the mounting angle of the first screw (perpendicular to the housing surface and the angle from the horizontal plane is approximately 0 degrees). It is preferable that the angle is in the range of 45 ° to 45 °, preferably about 45 °.

Accordingly, the pull-out strength of the case 2 attached to the housing 14 via the rear peripheral wall portion 25C of the bracket 22 is improved by combining the pull-out strength by the coach screw 15 and the shear strength by the course thread 16. To do.
That is, according to the method of attaching the case 2 to the housing 14 according to the embodiment, the case 2 is attached to the housing 14 using the coach screw 15 as the first screw and the course thread 16 as the second screw. 22 is fixed by fixing the rear peripheral wall portion 25C to the casing 14, and at this time, the course thread 16 is driven obliquely with respect to the surface of the casing 14 to reduce the shear resistance of the course thread 16 to the casing 2. Since it is made to resist the force which pulls out from 14 perpendicularly | vertically, the pull-out strength of case 2 attached to the housing 14 can be improved.

  In addition, an inclined flat plate portion 62 that extends in a direction intersecting the surface of the housing 14 in a state other than orthogonal to the surface of the housing 14 is formed on the rear peripheral wall portion 25C of the bracket 22 that functions as an attachment portion to the housing 14, and the inclined flat plate Since the second through-hole 61 for penetrating the course thread 16 is formed so as to penetrate the portion 62, the second through-hole 61 formed in the inclined flat plate portion 62 is in contact with the surface of the housing 14. In order to function as a guide hole when the course thread 16 is fastened to the housing 14 so as to be in an intersecting state other than orthogonal, when the course thread 16 is fastened so as to be in an intersecting state other than perpendicular to the surface of the housing 14 Improved workability.

Furthermore, conventionally, in order to improve the pull-out strength of the case, in order to improve the troublesome work of forming a hole for a through-bolt for penetrating the bolt in the case and the sitting of the head of the bolt with respect to the case A counterbore process is required for the housing, and when the counterbore process is performed, it is necessary to perform work from both one surface side (for example, the indoor side) and the other surface side (for example, the outdoor side) of the housing. However, according to the method of attaching the case 2 to the housing 14 according to the embodiment, there is a problem that a hole for a through bolt for penetrating the bolt is formed in the housing 14 according to the embodiment. Even if the work is not performed, the pull-out strength of the case 2 can be sufficiently increased only by a simple work of fastening the coach screw 15 and the course thread 16 from one surface side (for example, the indoor side) of the housing 14. Mounting structure for coercive be the case 2 so can be realized.

  That is, according to the method for attaching the case 2 to the housing 14 according to the embodiment, the workability of attaching the case 2 to the housing 14 can be improved, and the pull-out strength of the case 2 can be improved. That is, according to the embodiment, it is possible to provide a method of attaching the case 2 that can achieve securing of attachment strength and improvement of workability when attaching the case 2 to the housing 14.
