  When comparing the door portion 40 of the conventional enclosure structure with the large door 3 of the enclosure structure 1 of the present embodiment, as shown in FIG. 6, the rubber packing 41, 45, the opening / closing mechanism 47, etc. While various accessory parts are attached, as shown in FIG. 4, these various accessory parts are not provided on the inner side 3 b of the large door 3. When these various accessory parts 41, 45, 47 are provided, since the various accessory parts 41, 45, 47 form a large number of irregularities inside the door portion 40, cleaning is not easy. Moreover, it is easy for unwashed parts to be left on the concavo-convex portion, and there is a high possibility of becoming a nest of microorganisms.

  According to this embodiment, the large door 3 is not attached to the inner side 3b with various accessory parts such as the rubber packings 41 and 45 and the opening / closing mechanism 47. 3b is formed more flat. For this reason, while being able to wash | clean the inner side 3b more easily, the unwashed residue can be suppressed. In particular, it is necessary to increase the chance of cleaning in the enclosure of the seama because it is easy for germs to propagate due to the scattering of bubbles from the seama. . For this reason, the labor of cleaning can be greatly reduced by facilitating the cleaning of the inside such as the inner side 3b and suppressing the remaining washing. When applied to a seamer enclosure, it is not necessary to completely seal the inside of the enclosure structure 1 as long as scattering of scattered objects can be prevented.

  This invention is not limited to the above-mentioned form, It can implement with a suitable form. For example, in the above-described embodiment, the opening / closing mechanism is configured by cooperation of the handle portion 17 and each lock 15, but the present invention is not limited to such a configuration. For example, an opening / closing mechanism for opening and closing the door and a lock for locking may be provided as separate accessory parts that operate separately. For example, each lock 11 and 15 is not limited to the above-mentioned form constituted as a latch lock. Various locks may be applied as long as they can be attached to the outside of the door and the exposure of parts to the inside is suppressed. Similarly, various types of opening / closing mechanisms may be applied as long as exposure of components to the inside is suppressed.

  Moreover, although the auxiliary member 28 which fixes the handle | steering-wheel part 17 is provided in the inner side 3b of the large door 3 in the above-mentioned form, the structure which does not provide the auxiliary member 28 in the inner side 3b is not denied. That is, the handle part may be attached in such a configuration that no auxiliary member is provided inside the door. In this case, unevenness due to the auxiliary member is not formed inside the door. Moreover, in the above-mentioned form, although the polycarbonate 26 is being fixed to the inner side 3b of the large door 3 by the fixing member 27, it is not limited to such a structure. For example, glass may be attached so as to cover the window portion from the outside so that unevenness is not formed by a fixing member or the like inside the door. In these cases, since the inside of the door is formed more flat, the inside can be cleaned more easily.
