the handle member becomes rotatable by releasing the lock mechanism.
4 . The transfer device according to claim 3 , wherein
the handle member has a shaft portion extending in a direction intersecting a direction in which the support member extends, and a grasping portion bent from the shaft portion along the direction in which the support member extends, and
the handle member becomes rotatable by releasing the lock mechanism by extending the grasping portion along the direction intersecting the direction in which the support member extends.
5 . The transfer device according to claim 3 , wherein
the handle member becomes rotatable by releasing the lock mechanism by rotating the handle member sideways relative to the support member.
6 . The transfer device according to claim 1 , wherein
the handle member is removably attached to the support member.
7 . The transfer device according to claim 1 , wherein
the seat member is extendable in the front-back direction.
8 . The transfer device according to claim 1 , wherein
the seat member includes a seat portion on which the care-receiver is configured to be seated, and an extension and retraction mechanism configured to extend and retract the seat portion, and
the seat portion is removable from the extension and retraction mechanism.
9 . The transfer device according to claim 8 , wherein
the extension and retraction mechanism includes a scissors mechanism.
10 . The transfer device according to claim 1 , further comprising
a pair of base frames provided below the seat member, the base frames extending parallel to each other and rearward from lower end portions of the support frame, and
the at least one caster being attached to the base frames.
11 . The transfer device according to claim 10 , wherein
the base frames are laterally spaced away from each other.
12 . The transfer device according to claim 10 , further comprising
a foot rest disposed between the base frames.
13 . The transfer device according to claim 12 , wherein
the foot rest is disposed forward of the lower end portions of the support frame.
14 . The transfer device according to claim 1 , further comprising
a movable arm attaching the support member to the support frame, the movable arm supporting the support member in a cantilever manner at one end of lateral sides of the support member and being rotatable with the support member as the handle member moving in an up-down direction.
15 . The transfer device according to claim 14 , wherein
the handle member has a brake for stopping rotation of the at least one caster,
the transfer device further comprising
a first sensor configured to detect an active state or an inactive state of the brake,
a second sensor configured to detect rotation of the movable arm from an initial position, and
a drive mechanism configured to extend and retract the seat member based on detection results of the first sensor and the second sensor.
16 . The transfer device according to claim 1 , further comprising
a front holding portion disposed forward of the support frame below the seat member.
17 . The transfer device according to claim 16 , wherein
the front holding portion is arranged such that the front holding portion is configured to support a leg of the care-receiver.
18 . The transfer device according to claim 1 , further comprising
a back holding portion disposed rearward of the support frame above the seat member.
19 . The transfer device according to claim 18 , wherein
the back holding portion is arranged such that the back holding portion is configured to support a back of the care-receiver between the back holding portion and the support member.
