The base end portion of the lower surface part 31 of the lower side case 3 partially abuts against the longitudinal end of the horizontal piece 160 of the cross member 16, and is fixed to the longitudinal end of the horizontal piece 160 of the cross member 16 with a screw 310.

[0044] The upper side case 2 is placed with the main surface 220 of the side surface portion 22 of the upper side case 2 facing the upper portion of the outer surface of the face portion 10 of the bracket 1, and with the tip of the upper piece 230 of the upper reinforcing piece 23 of the upper side case 2 abutting against the edge 170 of the upper abutting piece 17 on the outer surface of the face portion 10, and the upper face portion 21 is abutted against the upper surface of the upper abutting piece 17, and the lower vertical edge 222 of the side surface portion 22 is placed on the outer side of the upper vertical edge 322 of the side surface portion 32, and the overlapping portion is fixed to the face portion 10 of the bracket 1 with screws 223 (see FIG. 6 ). The upper reinforcing piece 23 of the upper side case 2 and the upper abutting piece 17 provided on the outer surface of the face portion 10 of the bracket 1 function as positioning means when attaching the upper side case 2 to the bracket 1. The side portion of the side case (formed by side portion 22 and side portion 32) has a side recess C3 extending horizontally in the forward direction, and an overlapping portion (overlapping portion of vertical edge 222 and vertical edge 322) is formed at the bottom of side recess C3, and screw 223 is fixed to the bottom of side recess C3 so as not to be noticeable from the outside.

[0045] The lower vertical edge 202 of the front portion 20 of the upper side case 2 overlaps the outside of the upper vertical edge 302 of the front portion 30 of the lower side case 3, and an end recess C2 extending horizontally in the view direction is formed in the front portion of the side case (formed by the front portions 20 and 30), and an overlapping portion (overlapping portion of the vertical edges 202 and 302) is formed at the bottom of the end recess C2. As will be described later, the widthwise end of the recess C1 of this case overlaps the outside of the end recess C2, thereby forming an end overlapping portion (fourfold overlapping portion), and the end recess C2 (overlapping portion of the vertical edges 202 and 302) is connected to the cross member 14 by a screw 403 provided at the bottom of the widthwise end of the recess C1. The rising edge 210 at the base end of the top surface portion 21 of the upper side case 2 is fixed to the frame by a screw 211. The upper side case 2 and the lower side case 3 may be connected to the cross member 14 at the bottom (overlapping portion of the vertical side 202 and the vertical side 302) of the end recess C2 (portion excluding the end overlap recess C1').

[0046] In the side cases (upper side case 2, lower side case 3) according to this embodiment, the outer half of the visible width of the face parts (front face parts 20, 30, upper face part 21, lower face part 31) is located outside the face part 10 of the bracket 1, and the inner half of the visible width of the face parts (front face parts 20, 30, upper face part 21, lower face part 31) is located inside the face part 10 of the bracket 1. Both widthwise end portions of the face parts of this case are arranged to overlap from the outside with the inner half of the face parts of the side cases.

[0047] The outer half of the upper surface portion 21 of the upper side case 2 abuts against an inclined plane formed by the upper surface of the upper abutting piece 17 and the upper piece 230 of the upper reinforcing piece 23. The outer half of the lower surface portion 31 of the lower side case 3 abuts against the lower surface of the lower piece 330 of the lower reinforcing piece 33. When the lower surface of the lower abutting piece 18 and the lower surface of the lower piece 330 of the lower reinforcing piece 33 form the same horizontal plane, the outer half of the lower surface portion 31 of the lower side case 3 abuts against the horizontal plane. When the lower surface of the lower abutting piece 18 is located slightly higher than the lower surface of the lower piece 330 of the lower reinforcing piece 33, the outer half of the lower surface portion 31 of the lower side case 3 is close to the lower surface of the lower abutting piece 18.

[0048] [D] Book case The case according to this embodiment is formed from an upper case 4 and a lower case 5. The upper case 4 and the lower case 5 have the same front width, and the width dimension (front width) of the case is such that both widthwise ends partially overlap the front portions (front portions 20 and 30), upper surface portion 21, and lower surface portion 31 of the left and right side cases, and the case is adapted to be attached to the outer surfaces of the left and right side cases.

[0049] [D-1] Upper case 14, upper case 4 is made up of front surface portion 40 and top surface portion 41. Top surface portion 41 is an inclined surface that slopes gently downward toward the front, and has a rising edge 410 integrally formed at its base end. Front surface portion 40 is made up of main surface 400, which is a vertical surface, lower horizontal edge 401 that extends horizontally from the lower end of main surface 400 to the rear, and lower vertical edge 402 that hangs down from the tip of lower horizontal edge 401.

The front surface 50 is made up of a main surface 500 which is a vertical surface, an upper horizontal edge 501 which extends horizontally from the upper end of the main surface 500 to the rear, and an upper vertical edge 502 which rises vertically from the tip of the upper horizontal edge 501. The bottom surface 51 is a horizontal surface.

[0051] [D-3] Mounting structure of this case As shown in FIG. 18 , in this embodiment, the lower case 5 is attached before the upper case 4. Note that the order of attaching the lower case 5 and the upper case 4 may be reversed. Both widthwise ends of the lower case 5 are overlapped from the outside with the ends of the lower portions of the left and right side cases. Specifically, the ends of the main surface 500 of the front portion 50 partially overlap the outer surface of the main surface 300 of the front portion 30, the upper horizontal edge 501 of the front portion 50 partially overlaps the upper surface of the horizontal edge 301 of the front portion 30, the upper vertical edge 502 of the front portion 50 overlaps the outer surface of the bottom surface of the recess of the side case (the vertical edge 202 of the upper side case 2), and the widthwise ends of the lower surface portion 51 partially overlap the lower surface of the lower surface portion 31.

[0052] The base end portion of the underside portion 51 of the bottom case 5 is fixed to the horizontal piece 160 of the cross member 16 with screws 510 at multiple locations in the width direction, including both width direction end portions. The screws 510 at the width direction end portions are fixed to the horizontal piece 160 of the cross member 16 at the overlapping portion with the base end portion of the underside portion 31 of the side case. The screws 510 at the overlapping portion fix the underside portion 51, the underside portion 31, the horizontal piece 160, and the underside of the upper guide 12. Note that the screws 510 at the width direction end portions may fix the underside portion 51 to the cross member 16 not at the overlapping portion, but near the inside of the overlapping portion.

[0053] The lower end portion of the front portion 40 of the upper case 4 is overlapped with the upper end portion of the front portion 50 of the lower case 5. Specifically, the lower vertical edge 402 of the front portion 40 of the upper case 4 is overlapped with the outer surface of the upper vertical edge 502 of the front portion 50 of the lower case 5. A recess C1 extending horizontally in the view direction is formed in the front portion of this case (formed by the front portions 40 and 50), and an overlapping portion (the overlapping portion of the lower vertical edge 402 and the upper vertical edge 502) is formed at the bottom of the recess C1.

[0054] Both widthwise ends of the upper case 4 are overlapped from the outside with the ends of the upper portions of the left and right side cases. Specifically, the ends of the main surface 400 of the front portion 40 partially overlap the outer surface of the main surface 200 of the front portion 20, the lower horizontal edge 401 of the front portion 40 partially overlaps the lower surface of the horizontal edge 201 of the front portion 20, the lower vertical edge 402 of the front portion 40 overlaps the upper vertical edge 502 of the lower case 5 that overlaps the outer surface of the bottom surface of the recess of the side case (the vertical edge 202 of the upper side case 2), and the widthwise ends of the upper surface portion 41 partially overlap the upper surface of the upper surface portion 21.

[0055] The rising edge 410 on the base end side of the top surface portion 41 of the upper case 4 is fixed to the frame at multiple locations in the width direction, including both width direction end portions, with screws 411. The screws 411 at the width direction end portions are fixed to the frame at the overlapping portions with the rising edge 210 on the base end side of the top surface portion 21 of the side case. Note that the screws 411 at the width direction end portions may fix the top surface portion 41 to the frame not at the overlapping portions, but near the inside of the overlapping portions.

[0056] A recess C1 is formed in the front of the case from the lower end portion of the upper case 4 and the upper end portion of the lower case 5, and at the bottom of the recess C1, the lower vertical edge 402 of the upper case 4 and the upper vertical edge 502 of the lower case 5 overlap, forming an overlapping portion (see FIG. 3). Both widthwise ends of the overlapping portion overlap with the end recess C2 of the side case (the overlapping portion between the lower vertical edge 202 of the upper side case 2 and the upper vertical edge 302 of the lower side case 3), forming a quadruple overlapping portion (end overlapping portion) (see FIG. 5). Both widthwise ends of the recess C1 of the case partially overlap the end recess C2 of the side case to form an end overlapping recess C1', and the bottom of the end overlapping recess C1' forms a quadruple overlapping portion (end overlapping portion).

[0057] The overlapping portion is fixed to the vertical pieces 140 of the horizontal member 14 with screws 403 at multiple locations in the width direction, including both widthwise end portions (end overlapping portions). The screws 403 at both widthwise end portions are fixed to the vertical pieces 140 of the horizontal member 14 at the end overlapping portions. The overlapping portion consisting of the lower vertical edge 402 of the front portion 40 of the upper case 4 and the upper vertical edge 502 of the front portion 40 of the lower case 5 is formed at the bottom of a recess, and the screws 403 are fixed to the bottom of the recess C1 so as not to be visible from the outside. Note that the screws 403 at the widthwise end portions may fix the bottoms (402, 502) of the recess C1 to the horizontal member 14 not at the above-mentioned four-fold end overlapping portions (302, 202, 502, 403) but at overlapping portions (402, 502) near the inside of the above-mentioned four-fold end overlapping portions.

[0058] In the shutter case of this embodiment, the widthwise end portions of the case, which consists of an upper case 4 and a lower case 5, are arranged so as to overlap the outer surfaces (front portions 20, 30, upper surface portion 21, lower surface portion 31) of the left and right side cases (consisting of an upper side case 2 and a lower side case 3), and the case can be removed without removing the side cases.

[0059] In this case, the overlapping portion between the lower end portion of the upper case 4 and the upper end portion of the lower case 5 is formed by the lower vertical edge 402 of the front portion 40 of the upper case 4 and the upper vertical edge 502 of the front portion 40 of the lower case 5. In this embodiment, the lower vertical edge 402 of the upper case 4 is located outside the upper vertical edge 502 of the lower case 5, but by removing the screw 403 to release the connection between the lower vertical edge 402 and the upper vertical edge 502, and then removing the screw 510 and shifting the lower case 5 vertically downward, the upper vertical edge 502 of the lower case 5 can be moved downward relative to the lower vertical edge 402 of the upper case 4, and only the lower case 5 can be removed.

[0060] In the shutter case of this embodiment, the recess extending horizontally in the width direction (viewing direction) of the front part of the case, the recess extending horizontally in the width direction (viewing direction) of the front part of the side case, and the recess extending in the width direction (viewing direction) of the side part of the side case are continuous at the same height, and since the screws 403 and 223 are located at the bottom of the recesses, they are not noticeable from the outside, resulting in excellent design.
