うことができる。Therefore, since the end on the indoor side of the clutch piece 5 is fitted to the non-circular thumb-turn shaft 6 with the non-circular fitting hole 53, the shaft portion 41 of the cam 4 and the thumb-turn shaft 6 are rotated with respect to the rotation direction. Are integrally connected,
In this state, the locking and unlocking can be performed by either the thumb turn or the key inserted into the cylinder lock as in the case of the conventional final lock.

7, as shown in FIG. 7, slidably contacts at least one of the operating pins 51, and urges the operating pin 51 together with the clutch piece 5 to which it is fixed to the right non-coupling position in FIG. Since it is pushed in against the urging force of the means 7, the fitting hole 53 of the clutch piece 5 is
The connection state (fitting) between the and the thumb turn shaft 6 is released.
【0033】この作動状態では、サムターン軸6とカム

り、サムターンによる施解錠は不能となる。In this operating state, the connection between the thumb-turn shaft 6 and the shaft portion 41 of the cam 4 is disconnected, so that even if the thumb-turn on the indoor side is turned by hand, the thumb-turn will be idle, and the thumb-turn will not be performed. Locking and unlocking is not possible.
【0034】しかしながら、居住者等は外出に際し室外

まう。In this state, when the cam 4 is rotated by 90 ° with the key inserted into the cylinder lock, the passive pins 51 are disengaged from the operating member 8 as shown in FIG. Normally, the resilient force of the urging means 7 causes the clutch piece 5 to return to the coupling position with the thumb turn shaft 6 shown in FIG.
【0037】しかしながら、図示の実施例では、図5に

4に乗り上がるので、作動状態は保たれる。However, in the illustrated embodiment, as shown in FIG. 5, another passive pin 51 is implanted at an angle of 4:30 in terms of a clock face, and the cam 4 is rotated by 90 °. When the passive pin 51 is moved, the
Since the vehicle rides on No. 4, the operating state is maintained.
【0038】この余分の受動ピン51は、カム4の特定

ので、サムターンによる不正解錠は不能である。On the other hand, while a resident or the like is out, a person who intends to steal can break the window itself or the window glass provided near the door, insert his hand through the hole, and rotate the thumb turn. As described above, since the thumb turn shaft 6 only idles, unauthorized unlocking by the thumb turn is impossible.

極めて有効である。According to the security device of the present locking device according to the present invention described above, the door itself or the window glass provided in the vicinity thereof is broken, and a hand is inserted from there to rotate the thumb turn. However, since the resident or the like can cause the thumb turn shaft to idle with respect to the cam when going out, it is extremely effective in preventing unauthorized unlocking due to the thumb turn.
