The wheel means 12 is attached to the main frame, and the support frame 13 is fixed to the lower part of the main frame 11 so that a load can be carried. The above configuration is conventional and will not be further described. A feature of the present invention is that the foldable seat assembly 20 is provided on the rear side of the carrier. The foldable seat assembly comprises a sleeve means 21 slidably fitted to the first and second outer vertical rods 111, 112, a seat means 22 pivotally mounted on the sleeve means 21, and a first seat means 22. It comprises one pair of stands 23 and a second pair of stands 24.

Referring to FIG. 2, the seat means 22 includes a first seat support member 221 pivotally supported at one end of the sleeve means 21 and a first seat support member 221 pivotally supported at the other end of the connecting member of the sleeve means 21. A second seat support member 222, a connection member 223 having one end fixed to an intermediate portion of the first seat support member 221, and the other end fixed to an intermediate portion of the second seat support member 221; A first swinging member 224 that is pivotally supported at one end of the member 223 and has a first insertion hole (no number) at the other end, and one end is pivotally supported at the other end of the connecting member 223 and at the other end. A second swing member 225 having a second insertion hole (no number), a connecting rod 226 inserted in the first and second insertion holes, and a first and second seat support. A seat plate 229 fixed to the upper side surfaces of the holding members 221 and 222. The first and second rocking members 224, 225 are slidable with respect to the connecting rod 226. Details will be described later.

Referring to FIGS. 1 and 2, a first pair of stands 23 includes a first stand having an upper end pivotally supported at one end of a sleeve means 21 and an upper end at the other end of the sleeve means 21. It comprises a pivoted second stand and a first transverse member 233 connecting the first stand 231 and the second stand 232. The second pair of stands 24 comprises a third stand 242, a fourth stand 243 and a second cross member 113. The second pair of stands 24 comprises a third stand 242, a fourth stand 243 and a second cross member 113, the second cross member being fixed to the outer vertical rods 111 and 112. The third stand 242 and the fourth stand 243 are connected to the outer vertical rods 111 and 112, respectively. The third and fourth stands 242, 243 are each pivoted on the first transverse member 113.

Further, the middle portion of the first stand 231 is pivotally attached to the middle portion of the third stand 242 by a suitable means such as a bolt 241. The middle portion of the second stand 232 is pivotally attached to the middle portion of the fourth stand 243 by a suitable means such as a second bolt (not numbered). The first holding ring 261 is arranged between the first and third stands 231 and 242 at the pivot point (no number) of the first and third stands 231 and 242, and the bolt 241 is inserted therein. There is. The second retaining ring (unnumbered) is located between the second and fourth stands 232, 243 at the pivot point (unnumbered) of the second and fourth stands 232, 243.

The connecting member 223 may be fixed to the swinging member 224 and the swinging member 225 with screws or the like. Each of the seat support members 221 and 222 is provided with a cutout 227 so that the connection member 223 can be easily fitted to the swing members 224 and 225. In use, the folding seat assembly 20 is opened for the user to sit in, as shown in FIG. The lower ends of the first pair of stands 23 are in contact with the ground and stably support the seat together with the wheels 12. The upper ends of the second pair of stands 24 contact the lower surface of the seat plate 229 and support the seat plate 229. To fold the seat assembly 20, the user moves the seat plate 229 in the direction of arrow A, together with the first and second seat support members 221, 222 into a second pair of stands, as shown in FIG. Lift until 24 is substantially in line with rocker members 224 and 225 (note that first and second rocker members 224 and 225 are pivotally supported by connecting rod 226).

At the same time, the sleeve means 21 slides slightly downward. Then, the seat plate 229 and the seat supporting members 221 and 222 are pushed in the direction indicated by the arrow B until the seat supporting members 221 and 222 abut the second pair of stands 24. Therefore, by pushing the seat plate 229, the entire seat assembly is folded as shown in FIG. In FIG. 5 it can be seen that the sleeve means 21 slides upwards along the outer vertical rod. The support ring 26 fits into the notch 228 to prevent the folded seat assembly from squeaking and rattling. To open the folded seat assembly 20 as shown in FIG. 5 to the position shown in FIG. 3, the user may place the lower end of the seat plate 229 in the direction of arrow C in FIG. Is substantially open with the rocker members 224 and 225 until they are in a straight line as shown in FIG. 4 and the pivot point is pulled outward in the direction indicated by arrow D. It can be in a state. In this position, the upper ends of the second stand 242 and the fourth stand 243 contact the lower surface of the seat plate 229 to provide a stable seat for the user.
