It is formed in a parallelogram shape by a horizontal rail 61f extending horizontally in the direction of 61b. The first inclined rail 61a and the horizontal rail 61f are configured to be continuous, and the second inclined rail 61b is independent.

  The rotary link 65 is a link formed in a substantially L shape by a long side portion 65r and a short side portion 65s. The rotation link 65 includes a rotation center 65c at a boundary position between the long side portion 65r and the short side portion 65s. It is connected freely. The rotary link 65 is positioned so as to be able to rotate up and down in parallel with the guide rail 61. The front ends 65z of the short side portions 65s of the left and right rotating links 65 are connected to one end (left end) and the other end (right end) of the reinforcement 11z of the upper cover 11u so as to be vertically rotatable. Further, rollers 65e are rotatably mounted at the distal ends of the long side portions 65r of the left and right rotation links 65, respectively. The roller 65e of the left rotation link 65 is configured to roll along the first inclined rail 61a and the horizontal rail 61f of the guide rail 61. Further, the roller 65 e of the right rotation link 65 is configured to roll along the second inclined rail 61 a of the guide rail 61.

  As shown in FIG. 10, in the state where the movable mount 15 is in the retracted position (the left slide limit position), the rotation center 65c of the rotation link 65 is at the highest position, and the tip 65z of the short side portion 65s of the rotation link 65 is located. The connected upper cover 11u is at the lower limit position and is aligned with the lower cover 11d. In addition, the roller 65e of the long side portion 65r of the left rotation link 65 is located at the first inclined rail 61a of the guide rail 61, and the roller 65e of the long side portion 65r of the right rotation link 65 is the second of the guide rail 61.

As a result, the short sides 65s of the left and right rotary links 65 move upward, and the upper cover 11u connected to the tip 65z of the short sides 65s is gradually lifted. Then, after the long side 65r becomes the same angle as the first inclined rail 61a and the second inclined rail 61a of the guide rail 61 due to the left rotation of the left and right rotating links 65, the rollers 65e of the left and right rotating links 65 guide the guides. The rail 61 rolls along the first inclined rail 61a and the second inclined rail 61a.

Then, the roller 65e of the left rotation link 65 moves from the first inclined rail 61a to the horizontal rail 61f, and the left rotation of the left and right rotation links 65 at the timing when the roller 65e of the right rotation link 65 moves away from the second inclination rail 61b. Stops, and the upper cover 11u is held at the upper limit position. Then, in a state where the upper cover 11u is held at the upper limit position, the movable mount 15 slides rightward to the use position (right slide limit position). At this time, the roller 65e of the left rotation link 65 moves along the horizontal rail 61f to the right end position of the horizontal rail 61f, and the roller 65e of the right rotation link 65 remains detached from the second inclined rail 61b. Move to the right end position.
When the movable base 15 slides to the left from the use position (right slide limit position), the roller 65e of the left rotation link 65 moves along the horizontal rail 61f and then moves along the first inclined rail 61a. Further, the roller 65e of the right rotation link 65 contacts the second inclined rail 61b and then moves along the second inclined rail 61b. When the movable base 15 slides left from the vicinity of the storage position to the storage position (left slide limit position), the long side portions 65r of the left and right rotation links 65 are pulled rightward by the guide rails 61, and the left and right rotations are rotated. The link 65 rotates to the right. As a result, the upper cover 11u descends and covers the lower cover 11d.

Then, as shown in FIG. 7, after the protector 36 is lowered to the lower limit position with respect to the carrier 32, the wheelchair K is lowered alone, and the wheelchair K is separated from the wheelchair restraining plate 36 x of the protector 36. Then, the wheelchair K is lowered beside the driver's seat entrance / exit D of the car C.
Thus, since the wheelchair K is lowered to the side of the driver's seat entrance / exit D, the driver can easily transfer from the driver's seat of the automobile C to the wheelchair K.

Next, when the wheelchair K is stored, after the driver changes to the driver's seat, the hook 58 of the suspension device 50 is hung on the suspended object of the wheelchair K next to the driver's seat entrance / exit D. 50 is driven. Thereby, the wheelchair K is lifted and folded at the same time. In the lifting process, the wheelchair K comes into contact with the wheelchair restraining plate 36x of the protector 36 of the wheelchair support 30 from below. Thereby, the protector 36 is pulled up by the suspension device 50 together with the wheelchair K, and the protector 36 moves rearward while rising along the rail 33 of the carrier 32. Then, when the protector 36 is raised to the same height (upper limit position) as the carrier 32, the protector 36 is held at the same position in the vehicle longitudinal direction with respect to the carrier 32, and the suspension device 50 stops (see FIG. 6). . Next, the rotation mechanism 40 operates, the wheelchair support part 30 rotates from the vertical position to the horizontal position direction, and the wheelchair K is scooped up by the wheelchair support part 30. Then, as shown in FIG. 1B, the rotation mechanism 40 stops when the wheelchair support unit 30 reaches a horizontal position along the movable frame 15.
Next, the front and rear slide mechanisms 20 are driven, so that the movable base 15 slides to the left with respect to the fixed base 12. When the movable base 15 slides to the left from the vicinity of the storage position to the storage position (left slide limit position), the upper cover 11u is lowered by the action of the lifting mechanism 60 and is put on the lower cover 11d. In this state, the storage of the wheelchair K ends.
Even when the wheelchair K is not suspended, the wheelchair support part 30 and the like are stored in the above-described procedure.
