Claims (1)

[Claims for Utility Model Registration] A storage body drawer rail mechanism installed between the rectangular bottom surface of the storage body and the storage floor surface, which has a length corresponding to the pull-out distance and extends in the pull-out direction of the rectangular bottom surface. It is placed between both parallel ends and the storage floor, and each end consists of the following three rails: a lower rail fixed to the floor, and an upper rail fixed to both ends of the rectangular bottom. , and an intermediate rail placed between the upper rail and the lower rail, and each of these rails has the following structure. (a) The lower rail is an upward channel whose length direction is the pull-out direction, and two rollers at the front end of the channel groove whose axis direction is in the channel width direction sandwich the lower part of the channel of the intermediate rail, which will be described later. They are installed in parallel with a gap between them, and a roller guide is arranged at the upper end of one of the side walls of this channel, the lower surface of which is followed by the rollers of the intermediate rail, which will be described later. It is a channel with a two-stage side wall that is narrow and wide at the upper stage, and a rear end roller that follows the lower guide surface of the lower rail is installed on the outer side of the lower stage side wall, and at the front end of the rail there is a channel on the opposite side to which the rear end roller is installed. A roller that follows the lower part of the upper rail guide described below is installed on the inside of the upper side wall, and a guide that the lower part of the upper rail roller described later follows is installed at the top of the upper stage side wall on the side where the rear end roller is located. (c) The upper rail is a rod, and a roller is attached to its rear end to follow the lower surface of a guide attached to the upper end of the channel side wall of the intermediate rail, and on the opposite side to which this roller is attached, A guide is provided on the lower surface of which the roller at the front end of the intermediate rail follows. The mounting postures of the rollers on the intermediate rail and the upper rail are all the same as those of the lower roller.
