  When the controller 90 enters the straight-ahead mode, the controller 90 enters the holding release state R- as shown in FIG. At this time, as shown in FIG. 15B, even if the traveling platform 30 comes to the center of the turntable 40 and receives the detection signal, the turntable 40 is not rotated. Therefore, as shown in FIG. 15C, the traveling platform 30 goes straight as it is.

  On the other hand, when the control device 90 is set to the direction change mode, as shown in FIG. At this time, as shown in FIG. 16B, when the traveling platform 30 comes to the center of the turntable 40 and receives the detection signal, the turntable 40 is rotated by 90 ° as shown in FIG. The state is changed from one of the first state S1 and the second state S2 to the other (S1 to S2 in the figure). Thereafter, as shown in FIG. 16D, the holding release state R- is entered.

According to the present invention, the following effects can be obtained.
[A] Since the direction can be changed by changing from the first state S1 to the second state S2 or by changing from the second state S2 to the first state S1, it is not necessary to return the turntable 40 to the original state. The direction can be changed continuously.
[B] Since the turntable 40 only rotates within the range of 90 °, the wiring connected to the turntable 40 may be long enough to allow the 90 ° rotation, and the wiring and the like are entangled. Hard to twist or twist.
[C] Since the holding mechanism 60 is provided, the traveling platform 30 does not wobble when the turntable 40 rotates.
[D] Since the control device 90 is provided, the user of the care lift device 1 such as the walking handicapped person H or the caregiver only has to select the straight mode or the direction change mode. There is no need to operate each individually. Therefore, the operation is simple.
[E] In the direction change mode, when the traveling platform 30 collides with the holding member 61 without being stopped at the center of the turntable 40, the impact absorbing spring 67 is contracted to absorb the impact.
[F] The table rotation member 54 is switched from the first state S1 to the second state S2 by rotating 180 ° in the second rotation direction D2, and is further rotated by 180 ° in the second rotation direction D2. Switching from S2 to the first state S1 eliminates the need to reversely rotate the table motor 53.
[G] The holding member R + is switched from the holding state R + to the holding releasing state R− by rotating the cam rotating member 74 by 180 ° in the second rotating direction D2, and further holding is released by rotating 180 ° in the second rotating direction D2. Since the state R− is switched to the holding state R +, it is not necessary to reversely rotate the cam motor 73.
