In this state, the rear cover 2 can be easily moved forward by engaging the engagement protrusions 42 at the bottom of the back cover 2 with the engagement holes 29a formed at the back plate support plate 29 at the bottom of the front plate 1. It can be attached to the plate 1. In addition, since the engaging convex part 42 ... is formed with the inclined surface 42a which rises as it goes forward, the attachment of the back cover 2 to the front plate 1 can be performed smoothly with a small force.

  As shown in FIG. 5, projections 45, 45 projecting outward are formed on the left and right outer surfaces of the body plate 3 of the drawer 104 (105) at the portions where the convex portions such as the left and right rails 3 a, 3 a are not provided. Are formed integrally by pressing a press die from the inner surface side, and at the same time, engaging holes 45a and 45a in the front-rear direction are formed in the protrusions 45 and 45, respectively. Engagement holes 43a, 43a are formed in the left and right rear plates 43, 43 of the back cover 2 of the drawer 104 (105), and the locking holes 44a are formed in the left and right side plates 44, 44 of the back cover 2. 44a are formed.

  As will be described later, the anti-vibration body 141 is attached in a state where it is in contact with a portion where the convex portions such as the rails 3a and 3a on the left and right outer surfaces of the body plate 3 are not provided. Therefore, as shown in FIG. 6 and FIG. 7, a relatively large shape that is particularly long in the left-right direction can be obtained. As shown in FIG. 6, the anti-vibration body 141 includes a side plate 142 extending in the front-rear direction, a front plate 143 extending outward in the left-right direction at the front portion of the side plate 142, and provided on the outer side in the left-right direction of the front plate 143 Guide portions 144 and 144 composed of upper and lower horizontal plates connecting the protruding contact portion 146, the side plate 142 and the front plate 143, and a vertical connecting plate extending in the substantially left-right direction for connecting the upper and lower guide portions 144 and 144. 145 etc. are the main constituent members. And it is integrally molded with synthetic resin such as polyacetal, polypropylene, polyethylene terephthalate, nylon or ABS, and the main constituent members have a shape having high strength and rigidity as a whole.

  Further, as an attachment member for attaching the anti-vibration body 141 to the drawer 104 (105), it extends forward along the side plate 142 at a position spaced from the side plate 142 inward in the left-right direction (body plate 3 side). The engaging piece 142a is integrally formed with a locking piece 143a protruding forward on the inner side of the front plate 143 in the left-right direction.

  Therefore, the engagement pieces 142a and 142a of the anti-vibration bodies 141 and 141 are inserted from the rear side of the engagement holes 45a and 45a of the body plate 3, and the rear sides of the engagement holes 43a and 43a of the back cover 2 are inserted. The locking pieces 143a and 143a of the anti-vibration bodies 141 and 141 are inserted from the front and the front end hook-shaped portions of the locking pieces 143a and 143a are locked in the locking holes 44a and 44a of the back cover 2. For example, the left and right anti-vibration bodies 141 and 141 are easily attached to the body plate 3 and the back cover 2 in a state where the left and right outer surfaces of the body plate 3 are in contact with portions where the convex portions such as the rails 3a and 3a are not provided.

Therefore, the interval between the guide portions 144 and 144 of the left anti-vibration body 141 and the left front reinforcing body 121 and the interval between the guide portions 144 and 144 of the right anti-vibration body 141 and the right front reinforcing body 131 can be reduced. Therefore, the anti-vibration effect by the left and right anti-vibration bodies 141 and 141 can be enhanced.

  Further, when the drawer 104 (105) is closed from the state where the drawer 104 (105) is opened as shown in FIG. 7, the left and right front reinforcing bodies 121 and 131 (from the front side of the left and right side plates 107 and 107 of the wagon body 102) Since the front side of the side fence that has been stepped down is a stopper, the contact portions 146 and 146 of the left and right anti-vibration bodies 141 and 141 come into contact with the corresponding stopper, and the drawer 104 (105) and the wagon The impact caused by the collision with the main body 102 is reduced. Furthermore, with the strong stoppers composed of the left and right front reinforcing bodies 121 and 131, the drawer 104 (105) can be securely held and deformation of the corresponding stoppers can be suppressed.

  In the state in which the drawer 104 (105) is accommodated in the wagon body 102, the drawer front plate 1 is formed by the inner surfaces of the front end portions of the left and right side plates 107, 107 and the front surfaces of the left and right front reinforcing bodies 121, 131. Since the drawer front plate 1 is not visually recognized in a plan view and a side view, it is possible to give an impression of a clean appearance.

  Here, the front plate 143 of the anti-vibration body 141 provided with the corresponding contact portion 146 is positioned on the rear side of the drawer front plate 1, but the left and right anti-vibration bodies 141 and 141 have the strength and strength as a whole as described above. Since the shape is high and it is not directly attached to the front plate 1 but attached to the back cover 2 and the body plate 3, the force applied to the front plate 1 is small and the deformation of the front plate 1 is suppressed. Can do.

  Further, when the drawer 104 (105) is closed and the contact portions 146, 146 of the left and right anti-vibration bodies 141, 141 contact the left and right front reinforcement bodies 121, 131, the front reinforcement bodies 121, 131 and the side plate 107 107, as described above, the reinforcing strength and rigidity of the front reinforcing bodies 121 and 131 are high, and the engaging protrusions 107b of the left and right side plates 107 and 107, and the front reinforcing bodies 121 and 131, respectively. Are engaged with each other and are not integrated by welding or the like, so that almost no force is applied to the front end portions of the side plates 107, 107 of the wagon body 102. Therefore, deformation of the front end portion is suppressed.
