(8) In the packing box moving mechanism 100 according to the present embodiment, the packing box 103 that has moved backward from the loading platform 102 of the vehicle 101 via the tilting portion 104 is loaded on the rail portion 201 of the angle 200. As a result, the tilt portion 104 of the vehicle 101 and the rail portion 201 of the angle 200 are integrally connected. Therefore, the packing box 103 loaded on the loading platform 102 of the vehicle 101 can be easily moved onto the rail portion 201 of the angle 200 via the tilting portion 104.

(Modification example)
The above embodiment may have a configuration modified as follows.

In the above embodiment, an example in which a slide member provided with a plurality of rollers is arranged at the upper end portion of the tilt portion is shown, but the present invention is not limited to this. In the present invention, it is also possible to form a slide portion by arranging a plurality of rollers along the extending direction of the tilt portion at the upper end portion of the tilt portion. That is, it is also possible to have a configuration in which a plurality of rollers are attached to the upper end portion of the tilt portion. As a result, the jack support member can move along the front-rear direction of the vehicle on a plurality of rollers arranged at the upper end portion of the tilt portion. Therefore, the packing box can be easily moved along the front-rear direction of the vehicle as the jack support member moves.

In the above embodiment, an example is shown in which two packing box support members (four packing box support members when both sides are combined) support the packing box on one side in the vehicle width direction and raise and lower the packing box. Not limited to this. In the present invention, the number of packing box support members may be determined according to the size, weight, and the like of the packing box.

In the above embodiment, an example in which a slide portion is configured by using a plurality of rollers has been shown, but the present invention is not limited to this. In the present invention, if the slide portion can move along the tilt portion, it is preferable to provide a sheet or the like having a small resistance (slippery) instead of the plurality of rollers.

In the above embodiment, an example in which the slide member is arranged at the upper end portion of the tilt portion is shown, but the present invention is not limited to this, for example, additionally to the bottom surface portion of the loading platform of the vehicle or the bottom surface portion of the loading box. It is also possible to provide a slide member. In this case, it is advisable to provide a lock mechanism or the like in order to prevent the packing box from moving while the vehicle is running.

In the above embodiment, an example in which the bottom surface of the packing box is supported by the supporting portion of the packing box supporting member is shown, but the present invention is not limited to this. In the present invention, the side surface or the upper surface (top surface) of the packing box may be supported by the supporting portion of the packing box support member according to the size and weight of the packing box.

In the above embodiment, the power of the jack member is transmitted to the packing box support member via the connecting member, but the present invention is not limited to this. In the present invention, the power of the jack member may be directly transmitted to the packing box support member, or a plurality of members may be interposed between the jack member and the packing box support member.

All of the above embodiments are examples of the indications of the present invention, and it is natural that any other embodiment within the scope of the claims is included in the technical scope of the invention.
