The rotating shafts are fixed outward from both ends of the operating handle 3, and these are fitted and supported in the shaft supporting holes, whereby the operation handle 3 is fixed.
6 and the long shaft 46 are integrally rotated about the axis.

As shown in FIG. 1 and FIG.
At a substantially central position in a plan view of the long shaft 46 fixed to both ends of the character, an operation plate 41 in the form of an elliptical cam plate is fixed to the long shaft 46 obliquely downward toward the front. A shaft 48 is fixed to the distal end side of the operation plate 41 in a direction orthogonal to the front-rear direction. Therefore, the operation handle 36 rotates integrally with the long shaft about the rotation axis of the same shaft, and the operation plate 41 rotates and swings around the rotation axis on the front lower end side.

The underframe 14 is provided with stationary support means 16.

a and 32b are integrally rotated. The swinging leg is configured so that, from a state perpendicular to the underframe, further forward, the upper end of the swinging leg hits the underside of the underframe and does not rotate any more.

In the figure, each connecting shaft 32a, 32
b is connected and fixed at a position displaced rearward from the vertical center line at the upper end of the swing leg 28. Therefore, FIGS.
As shown in (2), when the state shifts from the stationary support state in which the entire base is supported only by the swinging legs 28 to the movable state by the moving means, it is difficult to rotate easily due to a large rotating torque, and therefore, the stationary support state , So that the entire underframe does not run away easily.

As shown in FIG. 1, among the swinging legs 28a to 28d, the swinging legs 28c and 28d are arranged near the corner of the rear end of the underframe 14. On the other hand, the swinging legs 28a and 28b are arranged near the front end of the underframe 14 substantially near the center in plan view. Regardless of the present embodiment, the swing leg may be formed such that the lower end portion of the vertically long substantially rectangular column is formed in a substantially downward arc shape or in a substantially elliptical shape in side view. It may be a rectangular plate. In short, it is only necessary to be able to hold the moving means such as wheels at a position separated from the grounding surface while supporting the underframe from the lower surface side.

As described above, the underframe supports the lower surface side of the underframe by the stationary support means including the swinging leg mechanism when fixed, and holds the moving means such as wheels at a position separated from the grounding surface. The load of the underframe or underframe-shaped load can be prevented from being applied to the moving means, so that the durability of the moving means is maintained, and even when the underframe needs to be moved urgently, it can be reliably and quickly performed. The device body is moved.
