  In this case, as described above, since the tacking plate is securely fixed in the door, the handle is also securely fixed to the door through the tacking plate.

Next, a first embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a door. An outer handle 2 as an external operation member is provided outside the door 1, and an inner handle 3 is integrally connected to the interior via a handle shaft 4. Yes.

  In the illustrated embodiment, a cross-sectional square hole that loosely fits with the handle shaft 4 is formed on the end surface of the outer handle 2 perpendicular to the door 1, and a square hole that fits together with the handle shaft 4 is formed on the inner handle 3. It is assumed that the inner handle and the handle shaft 4 are fixed by a set screw (not shown) that passes through a portion of the inner handle 3 that is perpendicular to the door 1, and the outer handle 2 and the handle shaft 4 are Then, it is fixed using elastic deformation of a locking plate, which will be described later.

  In addition to the handle, for example, a knob may be mounted as the external operation member. In this case, the knob and the handle are simply referred to as a handle.

  On the other hand, as shown in FIGS. 1 and 2, a retaining plate 6 having a square hole 5 loosely fitted with the handle shaft 4 in the middle of the outer surface of the door 1 is parallel to the inner and outer surfaces of the door 1. In addition, the square hole 5 is fixed so as to align with the handle shaft 4.

  That is, as shown in FIG. 1, a pair of round seats 7 and 7 are arranged on the door surface with the door 1 interposed therebetween, and these form mounting bolts 8 and 8 and female screw holes that penetrate the round seat 7. It is being fixed to the door so that it may call mutually via the attachment pillars 9 and 9 which are a pair of stepped cylindrical bodies.

  The retaining plate 6 is fixed in the door 1 while being sandwiched between the collar 11 fitted to the end of the mounting column 9 on the indoor side and the stepped portion of the mounting column 9.

  Incidentally, as shown in FIG. 2, the retaining plate 6 is rectangular, and U-shaped notches that are not numbered are formed at both ends in the length direction, and these notches are engaged with the mounting columns 9, 9. By doing so, it is firmly supported and fixed to the mounting column.

  Further, as described above, the dimension obtained by adding the thickness of the retaining plate 6 to the length of the collar 11 is set so as not to be smaller than the length of the small diameter portion of the mounting column 9.

  By configuring as described above, the notch portion of the fastening plate 6 is sandwiched between one end of the collar 11 fitted to the mounting column 9 and the step portion of the mounting column, for example, the right side in FIG. When the mounting bolt 8 passes through the round seat 7 and is screwed into the female screw hole in the small diameter portion of the mounting column, the stepped portion of the mounting column moves to the right. Attached.

  On the other hand, when the left mounting bolt 8 is passed through the circular seat 7 and screwed into the female screw hole of the large diameter portion of the mounting column 9, the left circular seat 7 is formed by the mounting column called rightward in FIG. Pushed to the right, the pair of round seats 7 and 7 is thus firmly fixed from both sides with the door 1 interposed therebetween.
