  For this reason, when the wheelchair K is lifted by the lifting device 30 in the state shown in FIG. 7, the wheelchair K is folded in the lifting process and comes into contact with the wheelchair restraining bar 24x of the movable frame 24 of the wheelchair support 20 from below. As a result, the wheelchair K is held in a fixed positional relationship with respect to the movable frame 24. When the wheelchair K is continuously lifted, the movable frame 24 rises together with the wheelchair K, and the movable frame 24 slides upward with respect to the fixed frame 22 of the wheelchair support unit 20. The movable frame 24 is held at the same height position as the fixed frame 22 in a state where the protector arm 24 a of the movable frame 24 has reached the position of the suspension base 26. This position is the upper limit position of the wheelchair K and the movable frame 24. When the belt 36 of the suspension device 30 is wound up from this state, the suspension fulcrum 26c of the suspension base 26 of the wheelchair support unit 20 is pulled toward the drum 32 side. As a result, the wheelchair support part 20 rotates upward about the bearing 21, and the wheelchair K is scooped up by the movable frame 24 and the fixed frame 22 of the wheelchair support part 20. As shown in FIG. 2, the motor unit of the suspension device 30 stops at the stage where the belt 36 is wound up to a position where the wheelchair support unit 20 becomes horizontal (wheelchair support position).

Further, when the suspension device 30 moves in a direction in which the belt 36 is fed out from a position where the wheelchair support portion 20 is horizontal (wheelchair support position), the wheelchair support portion 20 rotates downward by its own weight. When the wheelchair support unit 20 is rotated to a position perpendicular to the movable mount 15 (wheelchair receiving position), the wheelchair K and the movable frame 24 are lowered by their own weight as the belt 36 is extended. At this time, the movable frame 24 slides downward with respect to the fixed frame 22 by the action of the vertical slide mechanism 27, so that no rolling or the like occurs and the wheelchair K and the movable frame 24 may interfere with the body of the automobile 1.

Has been. The front and rear bearing portions 52 are positioned on the upper surfaces of the front beam portion 151 and the rear beam portion 152, respectively, so that the axes extend in the width direction of the front beam portion 151 and the rear beam portion 152. For this reason, the wheelchair fixing member 51 can be rotated upward around the front and rear bearing portions 52 from a position where the front and rear arms 53 are in contact with the upper surfaces of the front beam portion 151 and the rear beam portion 152.
The front and rear arms 52 are connected to one end of a first spring 57 for holding the wheelchair fixing member 51 in the upper limit standby position, and the other end of the first spring 57 covers the movable frame 15. It is connected to the inner wall surface of H (see FIG. 2). That is, in a state where no external force is applied to the wheelchair fixing member 51, the wheelchair fixing member 51 is held at the upper standby position by the spring force of the first spring 57.
The wheelchair fixing member 51 rotates the wheelchair K placed on the wheelchair support 20 by rotating downward from the standby position against the spring force of the first spring 57 by the action of the fixing member rotating mechanism 60 described later. It is comprised so that it can hold down from upper direction.
That is, the first spring 57 corresponds to the first elastic member of the present invention.

<About the fixing member rotating mechanism 60>
The fixing member rotating mechanism 60 uses the force when the movable base 15 slides in the storage position direction (left direction) with respect to the fixed base 12 to move the wheelchair fixing member 51 in the standby position to the first spring 57. It is a mechanism for rotating downward to the wheelchair holding position against the spring force. As shown in FIG. 1, the fixed member rotation mechanism 60 includes a lever 63 on the movable frame 15 side, a second coil spring 64, a guide plate 66 on the fixed frame 12 side, and the like.
The base end portion of the lever 63 is coupled to the fixed shaft 53j so that the lever 63 can rotate around the fixed shaft 53j of the bearing portion 52 of the wheelchair fixing mechanism 50. The lever 63 is a strip-like member shorter than the arm 53, and a roller 63r is mounted on the side surface of the tip. The lever 63 and the arm 53 are connected in the rotation direction by the second coil spring 64. Further, the spring constant of the second coil spring 64 is set to a value sufficiently larger than the spring constant of the first spring 57. For this reason, when the lever 63 rotates downward, the arm 53 is pulled downward via the second coil spring 64, and the arm 53 rotates downward against the first spring 57.

As shown in FIG. 1, the guide plate 66 constituting the fixed member rotating mechanism 60 is formed on the upper side surface of the support flat plate 65 fixed to the drive mechanism 40 of the fixed mount 12. The guide plate 66 is a member for rotating the lever 63 downward by guiding the roller 63r of the lever 63 when the movable mount 15 slides to the retracted position (left slide limit position). The support flat plate 65 that supports the guide plate is a vertical wall-like flat plate extending along the sliding direction of the movable mount 15, and the lower end edge of the support flat plate 65 is fixed to the case 40 c of the drive mechanism 40. The guide plate 66 is formed with a rolling surface 66f on the lower surface side of the guide plate 66 on which the roller 63r of the lever 63 comes into contact and rolls. The rolling surface 66f is formed so as to be highest at the right end position of the support flat plate 65 and gradually become lower as it approaches the left end position.
With the above configuration, when the movable gantry 15 slides to the storage position side (leftward) with respect to the fixed gantry 12, the roller 63r of the lever 63 on the movable gantry 15 side is moved near the storage position (left slide limit position). It abuts on the rolling surface 66f of the guide plate 66 on the side. When the movable base 15 further slides leftward from this state, the roller 63r of the lever 63 rolls along the rolling surface 66f of the guide plate 66, whereby the roller 63r is pushed down, and the lever 63 is moved downward. Rotate. Thereby, the arm 53 of the wheelchair fixing member 51 is pulled by the lever 63 via the second coil spring 64, and the wheelchair fixing member 51 rotates downward against the first spring 57. Then, the front and rear drive mechanisms 40 are stopped when the movable base 15 reaches the retracted position (left slide limit position). Accordingly, the lever 63 is held at the lower rotation limit position, and the wheelchair fixing member 51 is pulled by the lever 63 to rotate to the lower limit position (the wheelchair pressing position) and is held at that position. That is, the wheelchair K scooped up by the wheelchair support unit 20 is pressed by the wheelchair fixing member 51 with a force equal to the spring force of the second coil spring 64 in the retracted position, and is fixed on the wheelchair support unit 20.
That is, the second coil spring 64 corresponds to the second elastic member of the present invention.

The wheelchair K is folded during the lifting process and comes into contact with the wheelchair restraining bar 24x of the movable frame 24 of the wheelchair support 20 from below. Thereby, the movable frame 24 rises with the wheelchair K, and the movable frame 24 slides upward with respect to the fixed frame 22 of the wheelchair support part 20. Then, with the protector arm 24 a of the movable frame 24 reaching the position of the suspension base 26, the movable frame 24 is held at the same height position (upper limit position) as the fixed frame 22. When the belt 36 is further wound from this state, the wheelchair support part 20 is rotated upward, and the wheelchair K is scooped up by the wheelchair support part 20. And as shown in FIG. 2, the suspension apparatus 30 stops in the position (wheelchair support position) where the wheelchair support part 20 becomes horizontal.
Next, when the front and rear drive mechanisms 40 are driven, the movable gantry 15 slides leftward (from the use position toward the storage position) with respect to the fixed gantry 12. When the movable base 15 slides to the vicinity of the retracted position, the roller 63r of the lever 63 provided on the movable base 15 side comes into contact with the rolling surface 66f of the guide plate 66 provided on the fixed base 12 side. When the movable base 15 further slides to the left from this state, the roller 63r of the lever 63 rolls along the rolling surface 66f of the guide plate 66, whereby the roller 63r is pushed down, and the lever 63 rotates downward.
