た。 However, as shown in FIG. 2, the conventional latch mechanism 4 has a shaft 5 rotatably attached to the open end side edge of the upper frame 2 along its longitudinal direction. is provided with a finger 7 having a hook-shaped locking portion 6 at its lower end, and an operating portion 8 is provided at an appropriate position thereof, and a spring 9 and a stopper (not shown) are provided on the shaft 5 so that the shaft 5 can rotate within a predetermined range. Furthermore, a substantially inverted U-shaped hook 10 is provided on the side edge of the open end of the base frame 1 at a position corresponding to the finger 7, so that the upper frame 2 can be closed. At times, the locking portion 6 of the finger 7 locks on the hook 10 under the force of the spring 9,
Further, when opening the upper frame 2, the above-mentioned operating section 8 was operated to release the finger 7 from the hook 10.

あつた。 For this reason, the latch mechanism 4 becomes extremely complicated and expensive, and if the upper frame 2 is bent, the finger 7 may no longer be engaged with the hook 10, so the hook 10 is usually made larger than the finger 7. For this reason, the latch mechanism 4 cannot control the displacement (lateral displacement) in the longitudinal direction at the open end side edge of the upper frame 2, and the upper frame 2 is attached to the base frame. There was a problem in that an excessive load was placed on the rotating shaft 3 supported by the upper frame 1, and the upper frame 2 began to wobble after long-term use.
