[0098]

According to the first aspect of the present invention, the hook provided on the rear end of the rail is hooked on the fixed rotary roller. In addition, the bent piece provided at the rear end of the rail portion contacts the fixed rotating roller to prevent lateral movement, so that the locking portion of the rail portion does not come off from the fixed rotating roller, The position of the free end of the support member can be regulated. Therefore, the drawer-type door can be mounted safely and easily.

Specifically, when the storage case is removed, for example, when the storage case is cleaned, the drawer-type door is moved rearward again, and then, when the cleaned storage case is mounted, the drawer-type door is again mounted. When the door is moved in the forward direction, the pull-out door can be prevented from falling off, so that it is safe. Also, in the manufacturing process, after installing only the drawer door first, you can install only the storage case separately, so compared to the case where the storage case is combined with the drawer door and installed
Lighter weight makes handling easier and more options for process design.

According to the second aspect of the present invention, the projection is hooked on the pair of hooks provided near the opening of the storage chamber, and the bend is provided on the rear end of the rail. In order for the piece to contact the fixed rotating roller and prevent lateral movement,
The position of the free end of the support member can be regulated without the rear end of the rail portion coming off the fixed rotating roller. Therefore, the drawer-type door can be mounted safely and easily.

Specifically, when the storage case is removed, for example, when the storage case is cleaned, the drawer-type door is moved rearward again, and then, when the cleaned storage case is mounted, the drawer-type door is again mounted. When the door is moved in the forward direction, the pull-out door can be prevented from falling off, so that it is safe. Also, in the manufacturing process, after installing only the drawer door first, you can install only the storage case separately, so compared to the case where the storage case is combined with the drawer door and installed
Lighter weight makes handling easier and more options for process design.

According to the third aspect of the present invention, the entire area where the bent piece is provided or a part of the rail portion is formed with a convex portion protruding from another rail portion, so that the pull-out type is provided. The door is strongly recognized to be pulled out to the final position, and the pull-out door is lowered slightly forward so that the storage case can be smoothly attached and detached, and the position of the free end of the support member can be regulated. By making the rail width narrower than the rail width of other parts, the amount of bending of the bent piece, which is more convex than other parts of the rail part, can be increased by the narrower rail part width. Since the width of the material can be the same over the entire rail portion, the material can be efficiently used.

According to the fourth aspect of the present invention, the hook provided at the rear end of the rail is hooked on the fixed rotating roller, and the free ends of the support members are provided on both side walls of the storage chamber. Lateral movement is prevented by a pair of provided stoppers,
The position of the free end of the support member can be regulated without the engaging portion of the rail portion coming off the fixed rotating roller. Therefore, the drawer-type door can be mounted safely and easily.

Specifically, when the storage case is removed, for example, when the storage case is cleaned, the drawer-type door is moved rearward again, and then, when the cleaned storage case is mounted, the drawer-type door is used again. When the door is moved in the forward direction, the pull-out door can be prevented from falling off, so that it is safe. Also, in the manufacturing process, after installing only the drawer door first, you can install only the storage case separately, so compared to the case where the storage case is combined with the drawer door and installed
Lighter weight makes handling easier and more options for process design.

According to the fifth aspect of the present invention, the projections are hooked on the pair of hooks provided near the opening of the storage chamber, and the free ends of the support members are connected to the side walls of the storage chamber. The horizontal movement is prevented by a pair of contact portions provided on the support member, and the position of the free end of the support member can be regulated without the rear end of the rail portion coming off the fixed rotating roller. Therefore, the drawer-type door can be mounted safely and easily.

More specifically, when the storage case is removed, for example, when the storage case is cleaned, the drawer-type door is moved rearward again, and then, when the cleaned storage case is mounted, the drawer-type door is again mounted. When the door is moved in the forward direction, the pull-out door can be prevented from falling off, so that it is safe. Also, in the manufacturing process, after installing only the drawer door first, you can install only the storage case separately, so compared to the case where the storage case is combined with the drawer door and installed
Lighter weight makes handling easier and more options for process design.

According to the invention described in claim 6, the pull-out door can be opened and closed by providing the support member with the locking portion which engages with the flange portion of the storage case to prevent the storage case from moving backward. In this case, the storage case can be prevented from moving backward. In addition, the locking portion is inserted between the storage case and the flange portion behind the reinforcing rib to engage with the storage case, whereby the flange portion can be prevented from falling off from the support member.

According to the seventh aspect of the invention, the pull-out door is prevented from dropping forward due to a rotational moment about the fixed rotary roller. Therefore, the drawer-type door can be mounted safely. In addition, the drawer-type door or the support member does not hit the other drawer-type door below, so that damage or deformation can be prevented.

According to the eighth aspect of the present invention, when the rear end portion of the rail portion is mounted on the fixed rotating roller when the storage case is attached or detached, the pull-out door is lowered forward. By attaching the above-described rotation preventing portion to the storage case, the storage case can be easily attached and detached.

According to the ninth aspect of the present invention, since the fixing portion is formed integrally with the fixed guide,
The efficiency of materials, production, transportation, mounting and assembling, and the structural strength can be improved.
