Therefore, the description is omitted. In this embodiment, the second claw portions 62a and 62b are provided on the inner surfaces of the pair of guide wall portions 23a and 23b. As shown in FIG. 13, engagement concave portions 63 a and 63 b that fit into the second claw portions 62 a and 62 b are formed on a pair of upper and lower side surfaces of the fixed piece 5 of the hinge 4. The method of mounting the hinge mounting unit is the same as that of the hinge mounting unit of the first embodiment.

  FIG. 14 shows a bracket 71 of a hinge mounting unit according to the third embodiment of the present invention. In this embodiment, the positions of the slits 23a2 and 23b2 for forming the second claw portions 24a and 24b in a beam shape supported on both ends are different from the bracket of the first embodiment. In this embodiment, the slits 23a2 and 23b2 are formed in the pair of bottom guide walls 30a and 30b capable of guiding the bottom of the fixed piece 5 of the hinge 4. Since other configurations are the same as those of the bracket of the first embodiment, the same reference numerals are given and description thereof is omitted.

  FIG. 15 shows a bracket 81 of a hinge mounting unit according to the fourth embodiment of the present invention. The bracket 81 of this embodiment is similar to the bracket 61 of the second embodiment, but the flange wall portion 83 at the upper end of the pair of guide wall portions 82a and 82b is joined together and the pair of guide wall portions 82a. , 82b are connected to each other at the bottom wall 84 at the lower end. The pair of guide wall portions 82a and 82b, the flange wall portion 83, and the bottom wall portion 84 form a guide path having a square cross section. The fixed piece 5 of the hinge 4 is inserted into the guide path 85. A pair of first claw portions 86 a and 86 b is formed on the flange wall portion 83. Slits 87a and 87b are formed around the first claw portions 86a and 86b so that the first claw portions 86a and 86b are cantilevered. The flange wall 83 is formed with through holes 91a and 91b through which screws 50a and 50b (see FIG. 10C) for fastening the hinge fixing piece 5 to the side plate 7 of the housing 1 are passed. The second claw portions 88a and 88b are formed on the inner surfaces of the pair of guide wall portions 82a and 82b. A decorative plate 89 is coupled to the bracket main body 90 including the pair of guide wall portions 82a and 82b, the flange wall portion 83, and the bottom wall portion 84.

  The present invention is not limited to being embodied in the above-described embodiment, and can be variously modified without changing the gist of the present invention.

  For example, as the hinge, various types of hinges such as a four-joint can be used in addition to a hinge having a simple structure in which a fixed piece and a movable piece are rotatably connected by a single shaft. Also, at least one of the turning pair may be replaced with a sliding pair.

  In the above embodiment, the bracket is temporarily fixed to the housing first, and then the hinge fixing piece is temporarily fixed to the bracket. However, the hinge fixing piece may be temporarily fixed to the bracket first, and then the bracket may be temporarily fixed to the housing.

  The present invention effectively facilitates the mounting operation when the hinge fixing piece is attached to the housing after the hinge cup is attached to the door, but when the hinge that is not integrated with the door is attached to the housing. Is also applicable. This is because the through hole of the housing and the screw hole of the hinge can be accurately positioned by the bracket.

  The shape of the bracket is an example, and the shape can be variously changed without changing the gist of the present invention.
