  As shown in FIG. 5, the rear peripheral wall portion 25C is provided with a reference vertical flat plate portion 52 provided so as to extend at a right angle to the plate surface of the end surface plate 24 from the rear side (lower base 27) of the end surface plate 24. The reference vertical flat plate portion 52 is cut and raised to have an inclined flat plate portion 62 formed to be inclined with respect to the reference vertical flat plate portion 52, and the reference vertical flat plate portion 52 is cut and raised to A second through-hole 61 is formed which has an outer-tab attachment portion 53 formed to face in parallel, and the inclined flat-plate portion 62 penetrates the oblique thread thread 16 as a second screw. A first through hole 51 through which the coach screw 15 as a first screw is passed is formed in the vertical flat plate portion 52, and a through hole through which the coarse thread 15A for outer layer attachment is inserted into the outer layer attachment portion 53. 54 are formed It is a configuration.

That is, the rear peripheral wall portion 25C functions as an attachment portion to the housing 14, and as shown in FIG. 5, a first through hole 51 through which the coach screw 15 as a first screw penetrates, and a second screw And a second through hole 61 through which the course thread 16 passes.
The first through holes 51 are formed in the reference vertical flat plate portion 52 of the rear peripheral wall 25C opposite to the surface of the housing 14 in parallel.
The second through holes 61 are formed in the inclined flat plate portion 62 of the rear peripheral wall 25C extending in a direction intersecting with the surface of the housing 14 in a state other than orthogonal.
That is, the reference vertical flat plate portion 52 is formed to extend along the rear side (lower base 27) of the end face plate 24 so as to form a plate surface perpendicular to the plate surface of the end face 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 such that the center line of the hole is orthogonal to the plate surface of the reference vertical flat plate portion 52, and the center line of the hole is inclined in the second through hole 61 It is formed to be orthogonal to the plate surface of the flat portion 62. For example, the upper inclined flat plate portion 62 is formed to extend upward in the direction away from the housing 14, and the angle α between 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 in degrees.
Therefore, as shown in FIG. 2, an angle formed by the center line of the course thread 16 fastened to the casing 14 through the second through hole 61 formed in the upper inclined flat plate portion 62 and the surface of the casing 14. Is 65 °, and the course thread 16 is fastened to the surface of the housing 14 so as to be in a cross state other than orthogonal.
Further, as shown in FIG. 5, for example, the lower inclined flat plate portion 62 is formed to extend downward in the direction away from the housing 14, and the plate surface of the lower inclined flat plate portion 62 and the reference vertical flat plate portion The angle β with the plate surface of 52 is formed at 45 °.
Therefore, as shown in FIG. 2, the center line of the course thread 16 passed through the second through hole 61 formed in the lower inclined flat plate portion 62 and fastened to the casing 14 forms the surface of the casing 14. The angle is 45 °, and the course thread 16 is fastened to the surface of the housing 14 so as to be in a cross state other than orthogonal.
On the other hand, the angle between the center line of the coach screw 15 which passes through the first through hole 51 formed in the reference vertical flat plate portion 52 and fastened to the casing 14 and the surface of the casing 14 is 95 °. Is fastened to the housing 14 so as to be orthogonal to the surface of the housing 14.

  More specifically, on the upper side closer to the central portion between the upper and lower portions of the rear peripheral wall 25C of the bracket 22, a second penetration for passing the course thread 16 for attaching the rear peripheral wall 25C to the housing 14 The 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 formed on the lower side closer to the central portion between the upper and lower rear peripheral wall portions 25C of the bracket 22 A lower cut-and-raised piece is provided which functions as an inclined flat plate portion 62 in which a second through hole 61 for penetrating the course thread 16 to be attached to 14 is formed. In addition, a plurality of positions for attaching the rear peripheral wall 25C to the housing 14 at a plurality of positions separated by predetermined intervals along the vertical direction of the rear peripheral wall 25C of the bracket 22 are first The through hole 51 is formed.

Thus, as a first screw to be fastened to the casing 14 so that the rear peripheral wall 25C of the bracket 22 functioning as an attachment to the casing 14 in the case 2 is in a state orthogonal to the surface of the casing 14 And the coarse thread 16 as a second screw fastened to the housing 14 so as to be in a cross 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 mounting portion to the housing 14 to fasten the first screw to the housing 14 and is previously formed in the mounting portion to the housing 14 The case 2 is attached to the casing 14 by passing the second screw through the second through-hole 61 and fastening the second screw to the casing 14, and the attachment work for attaching the case 2 to the casing 14 Can be done easily and easily.
Here, the first screw attached in a state orthogonal to the surface of the housing 14 has a higher pull-out resistance than the shear resistance, and is attached to the surface of the housing 14 other than orthogonal. The screw of No. 2 is superior to the pullout strength in shear resistance. Also, the pull-out strength of the first screw is greater than the pull-out strength of the second screw, and the shear resistance of the second screw is more than the shear strength of the first screw. Preferably the strength is high.
Note that “perpendicular to the surface of the housing 14” is not only strictly meaning, but also for the attachment mode of the first screw, the formation error of the first through hole 51, etc., or the drainage of water that has entered the hole. In order to be able to effectively exert the pull-out strength in use even if the first screw is not strictly orthogonal to the surface of the housing 14 by intentionally fastening the first screw slightly downward. It can be regarded as substantially orthogonal.
Further, the term "other than perpendicular to the surface of the housing 14" means that the mounting angle of the second screw is a difference angle which can not be regarded as orthogonal so that shear resistance 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 surface of the housing and approximately 0 degrees from the horizontal surface), for example, 10 from the surface of the housing 14 It is preferable that the angle be in the range of 45 degrees, preferably about 45 degrees.

Therefore, the combination of the pullout resistance by the coach screw 15 and the shear resistance by the course thread 16 improves the pullout resistance of the case 2 attached to the housing 14 via the rear peripheral wall 25C of the bracket 22. Do.
That is, according to the method of attaching the case 2 to the casing 14 according to the embodiment, the attachment of the case 2 to the casing 14 is bracketed using the coach screw 15 as the first screw and the course thread 16 as the second screw. 22 by fixing the rear peripheral wall 25C to the casing 14. At this time, the shear resistance of the course sled 16 can be made by using the case 2 as a casing by obliquely driving the course thread 16 against the surface of the casing 14. Since the force to pull out vertically from 14 is made to resist, the pull-out resistance of the case 2 attached to the housing 14 can be improved.

  Further, an inclined flat plate portion 62 is formed on the rear peripheral wall 25C of the bracket 22 functioning as an attachment portion to the housing 14 so as to extend in a direction intersecting with the surface of the housing 14 in a state other than orthogonal. Since the second through hole 61 for penetrating the coarse thread 16 is formed to penetrate the portion 62, the second through hole 61 formed in the inclined flat plate portion 62 is opposed to the surface of the rod 14 When the course thread 16 is fastened to the surface of the housing 14 in a cross state other than orthogonal because it functions as a guide hole when fastening the course thread 16 to the housing 14 so as to be in a cross state other than orthogonal. Workability of is improved.

Furthermore, conventionally, in order to improve the pullout strength of the case, in order to improve the troublesome work of forming a hole for a through bolt for allowing the bolt to penetrate the case, and to improve the seating of the bolt head with respect to the case. When the counterbore processing is necessary for the housing and the counterbore processing is performed, it is necessary to work from both the 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 in terms of workability, and it is complicated such as forming a hole for a through bolt for causing the bolt to penetrate the housing 14. The pullout strength of the case 2 can be sufficiently improved by only a simple operation of fastening the coach screw 15 and the course thread 16 from one surface side (for example, the indoor side) of the housing 14 without performing various operations. 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 attachment workability of the case 2 to the housing 14 can be improved, and the pullout resistance of the case 2 can be improved. That is, according to the embodiment, it is possible to provide the method of attaching the case 2 that can realize securing of the attachment strength and improvement of the workability when attaching the case 2 to the housing 14.
