The guide hole 2 provided in the opening regulation piece 1 of the present invention is
As shown in FIG. 4, it is preferable that the main body 9 is formed along the central portion of the main body 9 in the lengthwise direction so that the door can be applied to either the left or right opening direction. Further, the leaf spring locking portion 5 for locking the latch pin 30 has a bending spring portion 6 at its tip and is screwed at the base end via an intervening piece 7. . FIG. 6 shows an embodiment in which the intervening piece 7 is formed as a separate body from a member, and FIG. 8 shows an embodiment in which it is integrally formed into a wing shape.

FIG. 1 shows an embodiment of the present invention according to claim 1.

That is, at the base end portion 3 of the opening control piece 1, there is formed a through hole 4 into which a collar 11 provided on a spindle 10 made of a screw rod is loosely inserted, and the upper surface and the lower surface of the through hole 4 are formed. An intervening piece 12 such as a washer having a through hole 13 formed in the same manner is arranged in the.

The collar 11 provided on the support shaft 10 is formed to have a length slightly larger than the total thickness of the intervening piece 12 and the opening regulating piece 1 whose lengths are overlapped with each other. 0.5m
It is desirable that the length exceeds m.

On the other hand, the base material 15 arranged on the back side of the frame 26 is formed with a screw hole 16 at an appropriate position for screwing the support shaft 10 as a screw rod.

Thus, the collar 11 interposed on the support shaft 10 is
12, insert the base end portion 3 of the opening control piece 1, the intervening piece 12 in this order,
And, while supporting the bottom end thereof on the upper surface of the base material 15,
The support shaft 10 that is inserted through the through hole 27 of the frame 26 is
It is screwed into the screw hole 16 arranged to face the through hole 27 on the back surface of the. In this case, in the support shaft 10 formed of a screw rod, the support rod portion 35 located above the male screw portion 36 located at the lower portion is formed to have a slightly larger diameter. Therefore, even during tightening, the support shaft 10 is locked to the base material 15 through the step portion 37, and the tightening force is not directly applied to the collar 11.

Therefore, according to the embodiment of the invention as set forth in claim 1, all the rotational movement of the opening degree restricting piece 1 is supported by the collar 11, and the rotational movement is directly transmitted to the support shaft 10.
