A structure in which a hollow portion of the seat is supported by a shaft 20 that is inserted through bearing metals 19, 19 fixed via brackets around outer portions of a tubular body 23 described later rotatably provided on the frame portions 6, 6, respectively. are doing.

Reference numeral 21 denotes a bridge seat, which is a smooth and thin plate, and is pivotally mounted on a bracket 15 and 16 mounted on the left and right upper frame portions 6 and 6 so as to be rotatable around a pin 24 in the front-rear direction inserted through the bracket. ing. More specifically, a thin iron plate 21b is stretched inside a pipe 21a forming an inverted U-shaped outer peripheral portion.
Are provided so as to be rotatable around. The left and right bridge seats 21 are provided with a cloth cover 25 that wraps the whole from above, and the left and right covers 25, 2 are provided.
5 are integrally connected by a seat cover portion that covers the seat 18 integrally. Reference numeral 23 denotes a cylindrical body which is rotatably attached to the upper frame portions 6, 6 via a bracket 22, and the upper side of the X-rotating connecting body 3 is fixed thereto.

[0012] 26 is a handrail, and integrally attached to the top of the handrail frame 27 which is pivotally mounted rotatably around the vertical middle portion outside of the rear frame section 5, the lower side of the handrail frame 27 is engaging member 28 to prevent collapse left and right bridge seat 21 sandwiches the pipe 21a of the bridge seat 21 from the right and left sides is attached. 29 is a handrail frame 27
5 shows a pin pivotally supporting the base side of a. 30 is a footrest, 31
Is a set holding rod of the X-rotating connector 3 for fixing the frame side and the connector.

[0013] In detail the operation of the above embodiment, the pipe is raised bridge seat 21 as in the FIGS. 1 and 2 in the case of nurse put a handicapped wheelchair is operated
The rail 21a is operated with the locking body 28 of the handrail frame 27 so as not to move left and right.
