Is preferred. By attaching the backrest portion to the side frame portion while changing the front and rear, the user can lean against the two front and rear backrest surfaces. Therefore, the consumption of the backrest surface can be reduced to about half of the usual amount.

Next, as in the fifth aspect of the present invention, it is preferable that a back support bar for supporting the back of the seat is provided on the backrest. This allows the backrest to have the role of a frame that supports the seat. Therefore, by attaching and detaching the backrest portion, the above-mentioned rear support bar located behind the seat portion can be easily attached and detached. Therefore, the seat portion can be stably supported, and the user can easily get on and off from behind the transfer device by removing the backrest portion.

Next, as in the sixth aspect of the present invention, it is preferable that the rear support bar is cantilevered at one of right and left ends of the backrest.
Thus, the seat portion can be easily engaged with the rear support rod.
