The caregiver can move the person being assisted M in the standing posture shown in FIG. 3 together with the assisting device 1, and transfer the person being assisted M to a place other than the chair C. As can be seen by comparing FIGS. 2 and 3, the support surface 521 of the fuselage receiving portion 52 in the transfer posture is closer to horizontal than the support surface 521 in the seated posture. Therefore, the person being assisted M can deposit his / her weight in the holding member 5 and move it in a comfortable posture.

Here, attention is paid to the position G of the center of gravity of the total weight including the weight of the person being assisted M held by the holding member 5 and the weight of the assisting device 1 itself. As shown in FIG. 3, the center of gravity position G is directly below the second handle portion 542 in the front-rear direction. In other words, the position of the second handle portion 542 coincides with the position of the center of gravity G in the front-rear direction. Therefore, when the caregiver grips the second handle portion 542, the movement operation force is easily applied and the movement operation force is easily transmitted to the assistance device 1. Therefore, lateral movement and super-credit turning become easy. In addition, the position of the assisting device 1 can be easily controlled.

It is more preferable that the position of the second handle portion 542 coincides with the position of the center of gravity G in the front-rear direction, but the position is not limited to this. That is, if at least a part of the second handle portion 542 is arranged on the lower side within the range in the front-rear direction of the holding member 5 in the transfer posture, the second handle portion 542 is located near the center of gravity position G in the front-rear direction. Therefore, the movement operability of the caregiver is improved. Similarly, the second handle portion 542 is at least below the holding member 5 in the transfer posture and at least between the front end of the holding member 5 and the rear end of the foot of the person being assisted M in the front-rear direction. If a part of the second handle portion 542 is arranged, the second handle portion 542 will be located in the vicinity of the center of gravity position G in the front-rear direction, and the movement operability of the caregiver will be improved.

Next, a case where the assistance device 1 is moved to the narrow toilet private room 91 and the person being assisted M is transferred to the Western-style toilet bowl 93 will be described. FIG. 6 is a plan view illustrating a situation in which the assistance device 1 is moved to the private toilet room 91 and the person being assisted M is transferred to the Western-style toilet bowl 93. In FIG. 6, the holding member 5 and the person being assisted M are not shown. As shown in FIG. 6, the entrance / exit 92 of the private toilet room 91 is provided on the side wall surface. Therefore, the caregiver retracts the assisting device 1 at the position indicated by the broken line while changing the direction, and also performs lateral movement and super-credit turning as necessary, and the front position of the Western-style toilet bowl 93 shown by the solid line. Need to move to.

Here, the recess 242 at the rear center of the footrest base 24 is formed to match the outer shape of the lower portion 94 of the Western-style toilet bowl 93. Therefore, the moving space is widened by the dent size of the recess 242 into which the lower portion 94 of the Western-style toilet bowl 93 can be engaged, and the assisting device 1 can be easily moved. Further, the presence of the recess 242 facilitates centering of the assistance device 1 with respect to the Western-style toilet bowl 93. For example, it is possible to first retract the assisting device 1 from an oblique direction so that the recess 242 comes into contact with the lower portion 94 of the Western-style toilet bowl 93, and then swivel the assisting device 1 around the recess 242.

In addition, the recess 242 gently acts on the seating motion of the person being assisted M. That is, since the person being assisted M can sufficiently approach the Western-style toilet bowl 93 by the size of the dent in the recess 242, there is no possibility of falling from the Western-style toilet bowl 93, and re-sitting due to shallow sitting is also reduced. Further, the standing operation of the person being assisted M becomes easy.
