By rotating the handle frame 14 around the pin 15, the vertical frame 20 of the handle frame 14 rises rearward and moves from a standing position along the frame 4 to a collapsed position where the vertical frame 20 of the handle frame 14 is approximately horizontal, and in multiple stages between both positions. It is possible to change its posture. When the vertical frame 20 of the handle frame 14 is in a reclined position where it is approximately horizontal, it is possible to lower one's back onto the lid 12 of the storage bag 10 while walking and use the handle frame 14 in the reclined position as a side rest. It's like this. In such a case, by lowering the lower back onto the lid 12 of the storage bag 10 and pressing the back of the lower back against the handle frame 14, the user can exercise to stretch the lower back. In such a case, the stopper 32 is moved to the rear wheel 9 by operating the operating lever 29, which will be described later.
The cane wheel A is fitted between the spokes 31 to prevent the cane wheel A from moving unexpectedly. or,
The cane wheel A is designed to be foldable into a compact size. The folding configuration will be explained below.

The rear rising frame 4 is divided into an upper half 4a and a lower half 4b below the horizontal frame 7,
These upper and lower halves 4a and 4b are pivotally connected by a horizontal shaft 37 so as to be freely rotatable. The connection points between the horizontal frame 7 and the upper half 4a, and the connection points between the horizontal shaft 7 and the front rising frame 5 are each pin 3.
They are pivotally connected at 8 for relative rotation. A locking pin 39 protrudes from the lower end of the upper half 4a, and a locking hook 40 is rotatably provided on the lower half 4b.By locking the locking hook 40 to the locking pin 39, the upper and lower The half parts 4a, 4b can be maintained in a linearly extended state. Then, the locking hook 40 is rotated to remove the locking hook 40 from the locking pin 39, and the upper half 4a is bent and rotated around the horizontal axis 37 with respect to the lower half 4b, as shown in FIG. Cane wheel A is made to be foldable as shown in the figure. During such folding, the horizontal frame 7 is raised and lowered while maintaining a substantially horizontal position. Next, the operation lever 29 and its folding structure will be explained.

As shown in FIG. 7, a bracket 42 is attached to the axle 41 of the rear wheel 8, and the lower end of the rod-shaped operating lever 29 is pivoted to the bracket 42 so as to be rotatable in the left and right directions using a pin 30 that faces approximately in the front-rear direction. It's worn. The tips of a pair of left and right stoppers 32 whose tips enter between the spokes 31 of the rear wheel 9 to prevent rotation of the rear wheel 9 are inserted into the through holes 43 of the lower half 4b of the rear rising frame 4, respectively. stopper 3
