The cam transmission mechanism 75 includes a roller 75a rotatably attached to the cam rotation member 74 and a slit 75b penetrating the disc cam 77 and extending in the radial direction of the disc cam 77. The roller 75a contacts the inner surface of the slit 75b.

When the cam rotation member 74 rotates 180° in the second rotation direction D2 from the state where the disc cam 77 is arranged at the non-pressed position P-, the cam transmission mechanism 75 turns the turn, as shown in FIG. The disc cam 77 is rotated relative to the table 40 in the second rotation direction D2. As a result, the disc cam 77 is displaced to the pressing position P+. The pressing position P+ is a position where the pressing protrusion 78 presses the holding member 61 so as to be fixed to the holding release position r− against the biasing force of the holding spring 65. As a result, as shown in FIG. 12B, the holding mechanism 60 enters the holding release state R-. The holding release state R- is a state in which the traveling of the traveling platform 30 from the edge side of the turntable 40 to the center side and the traveling from the center side to the edge side are permitted.

When the cam rotation member 74 rotates 180° in the second rotation direction D2 from the state where the disc cam 77 is arranged at the pressing position P+, the cam transmission mechanism 75 turns the turn, as shown in FIG. The disc cam 77 is rotated relative to the table 40 in the first rotation direction D1. As a result, the disc cam 77 is displaced to the non-pressing position P-. As a result, the holding mechanism 60 enters the holding state R+, as shown in FIG. The holding state R+ is a state in which traveling of the traveling platform 30 from the edge side of the turntable 40 to the center side is permitted, but traveling from the center side to the edge side is blocked.

As shown in FIG. 14, the care lift device 1 includes a detector 80 and a control device 90. The detector 80 includes a detector main body 85, a transmission member 81, and a return spring 82.

On the other hand, as shown in FIG. 14B, when the traveling table 30 comes to the center of the turntable 40, the transmission member 81 is pushed up by the traveling table 30 and does not press the switch 86. The detector main body 85 transmits a detection signal to the control device 90 when the switch 86 is no longer pressed.

As shown in FIG. 14C, the control device 90 controls the table motor 53 and the cam motor 73 based on the detection signal. The controller 90 is configured to be switchable between a straight traveling mode and a direction changing mode by the controller 95.

When the control device 90 is set in the straight traveling mode, the control device 90 sets the holding release state R- as shown in FIG. At this time, as shown in FIG. 15B, the turntable 40 does not rotate even if the traveling platform 30 comes to the center of the turntable 40 and receives a detection signal. Therefore, as shown in FIG. 15C, the traveling platform 30 goes straight on.

On the other hand, when the control device 90 is set in the direction changing mode, the control device 90 sets the holding state R+ as shown in FIG. At this time, as shown in FIG. 16(b), 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. 16(c). One of the first state S1 and the second state S2 is changed to the other (from S1 to S2 in the figure). Thereafter, as shown in FIG. 16D, the holding release state R- is set.

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 from the second state S2 to the first state S1, it is not necessary to return the turntable 40 to the original state. You can change direction continuously.
[B] Since the turntable 40 only rotates within a range of 90°, the wiring or the like connected to the turntable 40 may have a length that allows the rotation of 90°, and the wiring or the like is entangled. It is hard to twist or twist.
[C] Since the holding mechanism 60 is provided, the traveling platform 30 does not sway when the turntable 40 rotates.
[D] Since there is the control device 90, the user of the care lift device 1, such as the walking-impaired person H or his/her caregiver, only needs to select the straight traveling mode or the direction changing mode. There is no need to operate each separately. Therefore, the operation is easy.
In the [E] direction changing mode, when the traveling platform 30 collides with the holding member 61 without stopping at the center of the turntable 40, the impact absorbing spring 67 contracts to absorb the impact.
[F] The table rotation member 54 is rotated 180° in the second rotation direction D2 to switch from the first state S1 to the second state S2, and further rotated 180° in the second rotation direction D2 to be in the second state. Since the state is switched from S2 to the first state S1, it is not necessary to rotate the table motor 53 in the reverse direction.
[G] The holding state R+ is switched to the holding release state R- by rotating the cam rotation member 74 by 180 degrees in the second rotation direction D2, and the holding state is released by further rotating 180 degrees in the second rotation direction D2. Since the state R- is switched to the holding state R+, it is not necessary to rotate the cam motor 73 in the reverse direction.
