The mounting hole 20 that substantially coincides with is formed. However, the recessed part 22 which supports a leaf | plate spring is formed in the both-sides edge 21 extended in the vertical direction Y of the attachment hole 20. As shown in FIG.

  The handle body 4 as described above is attached to the door 2. Before the handle body 4 is attached to the door 2, the first mechanism 6, the second mechanism 8, and the cover 9 are joined, and these are integrally formed. Such a handle body 4 is pressed so as to be fitted toward the mounting hole 20 of the door 2. When the handle body 4 is pressed, the leaf springs 80 of the second mechanism 8 are pressed against the side edges 21 of the mounting hole 20. That is, the second spring portion 82 is pressed against the recess portion 22, and is slid against the recess portion 22 while the second spring portion 82 is pressed against the biasing force. Head to the back. When the second spring portion 82 passes through the recessed portion 22, the free end edge 87 of the second spring portion 82 is restored and expanded outward in the lateral direction X by the urging of the spring member, and comes into contact with the back surface of the door 2. In this manner, the free end edge 87 of the second spring portion 82 is restored and expanded and comes into contact with the back surface of the door 2, thereby preventing the handle body 4 from coming off.

When the handle body 4 is pressed against the mounting hole 20 of the door 2, the inclined portions 64 and 65 formed on the upper and lower claw members 61 and 62 of the first mechanism 6 abut on the upper and lower edges 23 and 24 of the mounting hole 20. When the handle main body 4 is further pressed, the inclined portions 64 and 65 slide with respect to the upper and lower end edges 23 and 24, and the coil spring 60 is compressed in the longitudinal direction Y toward the depth of the mounting hole 20. When the inclined portions 64, 65 exceed the upper and lower edges 23, 24, the upper and lower claw members 61, 62 are restored and expanded outward in the vertical direction Y by the bias of the coil spring 60, and the vertical portions 66, 67 are formed in the mounting holes 20. Abuts on the upper and lower edges 23 and 24. Thus, the upper and lower claw members 61 and 62 are restored and expanded in the vertical direction Y, and the vertical portions 66 and 67 abut against the mounting hole 20 of the door 2, thereby preventing the handle body 4 from coming off. Further, since the vertical portions 66 and 67 are urged in the vertical direction Y by the coil spring 60, the vertical movement Y of the handle body 4 with respect to the mounting hole 20 can be prevented. Since the handle body 4 can be prevented from rattling with respect to the mounting hole 20 of the door 2, the door is opened and closed smoothly, and no collision noise due to rattling is generated.
Moreover, since the both side edges 21 of the attachment hole 20 should just have the magnitude | size which the 2nd spring part 82 can slide, it is necessary to enlarge the space | interval with the attachment hole 20 in the horizontal direction X of the handle main body 4. There is no large backlash.

  Since it is only necessary to form a mounting hole for mounting the handle main body 4 in the door 2, no other special processing steps are required, and the manufacturing cost can be reduced. Moreover, since these can be attached only by pressing the handle main body 4 to the attachment hole 20 of the door 2, it is not necessary to use a screw etc. in order to attach the handle main body 4 to the door 2, and it is easy and for a short time. Can be installed. By attaching the holding member 63 to the handle body 4, the holding member 63 can be used as a gripping part, so that it is not necessary to form a special gripping part, and the manufacturing cost can be reduced correspondingly. The pipe part 68 of the holding member 63 can be gripped. Since the pipe part 68 has a cylindrical shape, it is easy to adjust to the hand when gripping this, and the opening / closing operation can be facilitated.
