Then (at the moment when the tip of the handle shaft 3 is pushed into the attachment hole 40 of the stopper plate 4), the locking claws 35C of the respective stopper hooks 35 are completely retracted into the respective stopper hook mounting recesses 33, and the handle The tip of the shaft 3 completely passes through the mounting hole 40 of the stopper plate 4, and the back surface of the handle mounting portion 103 of the handle case 1 abuts the entire periphery of the mounting hole 40 on the front side of the stopper plate 4. The biasing force of the coil spring 37 between the respective clasp hooks 35 (coil spring 37) on the rear side of the clasp 4 due to the clasp hooks 35 in the respective clasp hook mounting recesses 33 passing through the mounting holes 40 of the clasp 4. (Resilient return of each), each locking claw 35C of each clasp hook 35 is rotated outward from each clasp hook mounting recess 33 to be projected outward from each clasp hook mounting recess 33, and The upper and lower edges of the mounting hole 40 are elastically locked. Here, in this clasp hook 35, as shown in FIG. 6, the rotation center C2 of each clasp hook 35 is on the one end 35a side of each clasp hook 35, and the outer surface 35d and the inner surface 35e. The other end 35f of each clasp hook 35 is provided a little closer to the outer surface 35d between them, and the center of the circle is located closer to one end 35a of each clasp hook 35 than the rotation center C2 of each clasp hook 35. Since the stopper hooks 35 are formed in the shape of an arc placed near and closer to the inner surface 35e, the stopper hooks 35C rotate outwardly of the stopper claws 35C and the arcuate portions of the stopper claws 35C stop. No. 4 of the mounting hole 40 protrudes toward the upper and lower edges of the mounting hole 40 and bites into the upper and lower edges of the mounting hole 40, whereby the back surface of the handle mounting portion 103 of the handle case 1 is in front of the stopper plate 4.

The door handle is pressed against the periphery of the opening of the mounting opening, and the locking claws 15C of the case hooks 15 are locked to the edge of the mounting opening or the periphery of the mounting opening on the back side of the door panel, so that the door handle is closed. Since the handle case 1 is attached to the door panel with one touch, the handle case 1 can be attached simply and securely with one touch without using screws, and the installation work can be greatly improved. Further, by not using the mounting screw, the number of parts required for mounting the handle H can be significantly reduced, and the cost can be significantly reduced.

Further, the handle H has the following advantages.
(1) In each case hook 15, the shaft insertion portion 150 is provided as the rotation center C1 between the both side surface portions 15b and 15c on the one end portion 15a side, and the other end portion 15f has the center of the circle as the rotation center. Since it is formed in an arcuate shape at a position closer to one end 15a than C1 and closer to the inner surface 15e opposite to the outer surface 15d, after the handle case 1 is pushed through the mounting opening of the door panel and one push is performed. As each of the case hooks 15 rotates outwardly of the locking claws 15C, the arcuate portion of the locking claws 15C protrudes toward the edge of the mounting opening and bites into the edge of the mounting opening. By this, the flange 11 of the handle H is pressed around the entire periphery of the mounting opening, and the door panel is tightened between the flange 11 of the handle H and each pair of case hooks 15.
