Next, a description will be given of a vehicle window opening and closing device. As shown in FIGS. 5 and 6, the window handle 18 is attached to a handle plate 35 fixed so as to sandwich the glass surface from inside and outside of the window 14.
The lower end of the window handle 18 is formed to be rotatable by approximately 90 degrees from the downward position to the forward position. A locking piece 36 is projected from the window handle 18 in a direction substantially perpendicular to the longitudinal direction in a side view, and when the lower end of the window handle 18 is positioned vertically downward. Are formed so as to face rearward of the wind handle 18. At this time, the locking piece 36 is locked to the stopper 38 of the rear window frame 37, and is locked in a closed state so that the window 14 does not open outward. Furthermore,
A cushion member 39 having a flat conical head is fixed to the outside of the wind handle 18.

Here, one hinge plate 15b of the hinge 15 is attached to the front edge of the window 14, and the other hinge plate 15c is attached to the rear edge of the door 13, so that each of the windows 14 and the door 13 Are formed so as to open and close about the same axis with the hinge pin 15a as a fulcrum. L-shaped bracket 4 inside the cabin of the hinge plate 15b on the window side
The cylinder case side hinge 41a of the damper 41, which is a window urging means, is fixed to the horizontal surface of the bracket 40.
And mounted so that the damper 41 can rotate in the horizontal direction.

A bracket 42 is fixed to the rear window frame 37 of the cabin, and a rod-side hinge 41b of the damper 41 is pivotally mounted on a horizontal surface of the bracket 42. The damper 41 is urged in a direction in which the rod protrudes, and as shown in the figure, the damper 41 is interposed between the window side bracket 40 and the cabin side bracket 42 in a compressed state.

As shown by the two-dot chain line in FIG. 5, after the window handle 18 is rotated in the horizontal direction to unlock the window 14 from the closed state, the window handle 18 is unlocked.
