The angle theta L at which the second part 244b is bent from the first part 244a can be an acute angle. The third part 244c can be bent from the second part 244b in a first direction, and the third part 244c and the second part 244b can have an overall v or u shape. The fourth part 244d can be bent from the third part 244c in a second direction opposite to the first direction, and the fourth part 244d and the third part 244c can have an overall inverted v or inverted u shape. For example, the angle between the fourth part 244d and the third part 244c can be greater than the angle between the third part 244c and the second part 244b.

[0122] The user can move the inner lid 250 so that the holder 254 of the inner lid 250 catches onto the catch 244 of the intermediate frame 240. The fourth part 244d of the catch 244 can be inserted into the hole 254h of the holder 254, and the rear boundary of the hole 254h can catch onto the end of the fourth part 244d. A rib 254r can be formed on one side of the holder 254 to increase the rigidity of the holder 254. The catch 244 and the holder 254 can be referred to as the fourth coupling group 244, 254. The user can press the holder 254 placed on the fourth part 244d of the catch 244 rearward to bend the catch 244, and the holder 254 can move rearward toward the bent catch 244. Then, the holder 254 can catch onto the catch 244 that returns to its original state.

[0123] Thereby, the portion adjacent to the lower edge of the inner lid 250, the lower left part, and the lower right part can be held by the intermediate frame 240. That is, the inner lid 250 can be coupled to the intermediate frame 240.

[0124] At this time, the first coupling group 241, 251 (refer to Figure 23 D) and the second coupling group 242, 252 (refer to Figure 23 E) can be located above the horizontal line passing through the center of the inner lid 250, and the fourth coupling group 244, 254 (refer to Figure 23 G) can be located below the horizontal line passing through the center of the inner lid 250. The third coupling group 243, 253 (refer to Figure 23 F) can be located near the center of the inner lid 250. The portion of the inner lid 250 above the horizontal line can be referred to as the upper part of the inner lid 250, and the portion of the inner lid 250 below the horizontal line can be referred to as the lower part of the inner lid 250. That is, the user can use the first coupling group 241, 251 (refer to Figure 23 D) and the second coupling group 242, 252 (refer to Figure 23E) The upper border vicinity of the inner lid 250 can be joined to the middle frame 240, and the fourth coupling groups 244, 254 (refer to Figure 23 G) The lower border vicinity of the inner lid 250 can be joined to the middle frame 240. Additionally, since the third coupling groups 243, 253 (refer to Figure 23 F) The center vicinity of the inner lid 250 can be joined to the middle frame 240, the amount by which the center vicinity of the inner lid 250 floats can be minimized.

[0125] A user can insert a tool (HR) between the side portion 240S of the middle frame 240 and the inner lid 250. The tool (HR) can be referred to as a bar (HR), a plate (HR), a spatula (HR), or a hera (HR). The user can rotate the tool (HR) in one direction DR1 to push the first portion 244a and / or the second portion 244b, whereby the catch 244 can be removed from the hole 254h of the retaining member 254. The first point P1 can be a force point, and the second point P2 can be a fulcrum point. At this time, since the second portion 244b is bent from the first portion 244a (refer to theta L), the user can flip the catch 244 by applying a relatively small force to the tool (HR). Thereby, the user can release the engagement of the seven said fourth coupling groups 244, 254 (refer to Figure 23 G). Then, the user can release the engagement of the two said third coupling groups 243, 253 (refer to Figure 23 F), the engagement of the two second coupling groups 242, 252 (refer to Figure 23 E), and the engagement of the four first coupling groups 241, 251 (refer to Figure 23 D).

[0126] Thereby, the inner lid 250 can be separated from the middle frame 240. That is, the inner lid 250 can be easily joined to or separated from the middle frame 240, so that damage to the inner lid 250 and / or the middle frame 240 during the assembly and disassembly of the inner lid 250 and the middle frame 240 can be minimized.

[0127] For example, the user can separate the inner lid 250 from the middle frame 240 on the grounds of removing contaminants from the cover 250B made of a fabric material, etc., or replace the existing inner lid 250 with a new inner lid 250 on the grounds of changing the color or pattern of the cover 250B made of a fabric material, etc.

[0128] On the other hand, the side portion 240S of the intermediate frame 240 may form a step that becomes higher toward the front from the base portion 240P of the intermediate frame 240. The intermediate frame 240 may include a first portion 240Sa, a second portion 240Sb, and a third portion 240Sc. The first portion 240Sa may be bent forward from the periphery of the base portion 240P. The second portion 240Sb may be bent horizontally from the front end of the first portion 240Sa. The third portion 240Sc may be bent backward from the end of the second portion 240Sb. The first portion 240Sa, the second portion 240Sb, and the third portion 240Sc may have a U-shaped cross section. A plurality of front ends of the plurality of side ribs SR formed on the inner side of the side portion 212 of the outer cover 210 may support the rear end of the third portion 240Sc. A plurality of front ends of the plurality of corner ribs CR (refer to Figure 13 ) formed at the corners formed in the side portion 212 of the outer cover 210 may also support the rear end of the third portion 240Sc.
