Will be described with reference to. As described above, in the “initial position”, the picking portion 20 of the picking operation member 6 has the guide window 5 of the case body 5.
It is located at the bottom of a. In this case, the locking piece 4 projects,
It hangs on the metal fitting of the outer sliding door.

い。However, the upward force applied to the knob operating member 6 pushes the engaging portion 36 of the lock piece 30 against the notched end surface of the engaging groove 16 of the lid body 8 as a fixing member, and as a result, locks. Even if the piece 30 tries to rotate counterclockwise,
The lock piece 30 is provided between the knob operating member 6 and the support plate 40 so as to move together with the knob operating member 6, and
Since the contact portion 35 of the lock piece 30 contacts the stopper 50 of the lock release operation piece 42, this becomes an obstacle,
As it is, the lock piece 30 cannot rotate.

反時計方向に回転可能な状態となる。FIG. 13 is an explanatory diagram when the lock piece 30 rotates. In this case, in order to eliminate the obstacle to the lock piece 30, first, the pinching tip portion 49 of the unlocking operation piece 42 is pushed down in the direction of arrow A with, for example, one finger of the left hand. When the flat tip portion 49 is pushed down, the unlocking operation piece 42 rotates counterclockwise around the support shaft 41 against the spring force of the spring 52. Then, since the rear end portion 48 of the unlocking operation piece 42 is in a floating state,
The stopper 50 is no longer in the way, and the lock piece 30 is rotatable in the counterclockwise direction.

The operating member 6 is lifted as it is in the direction of the arrow B (second action operation).

Is externally fitted to a wall portion having a fitting recess 9A formed on the back side of the case body 5A and a small cutout portion 9a (a portion corresponding to the engagement groove 16A of the lid 8A having an arbitrary shape). In addition,
In this case, the engaging portion 36 of the lock piece 30 can be locked to the end face of the notch 9a of the inner case body, but since the case body 5A is made of a synthetic resin material, the notch 9a is formed. The engagement groove 36A of the lid 8A is slightly larger than the engagement groove 16A, and the engagement portion 36 of the lock piece 30 is engaged with the notched end surface 16a of the metal lid 8A.

製蓋体８Ｂの切欠端面１６ａに係止させている。In the third embodiment as well, as in the second embodiment, the case body 5B is made of a synthetic resin material, so that the notch 9a of the case body 5B is more than the engagement groove 16B of the lid 8B. The engagement portion 36 of the lock piece 30 is made slightly larger and is engaged with the notched end surface 16a of the metal lid 8B.

実施例の作用は同じである。Then, the release portion 65 of the lock release operation piece 42B rotates about the support shaft 41 against the spring force of the spring 52B. As a result, the lock piece release portion 65 corresponding to the rear end portion of the lock release operation piece 42B is in a floating state, so that the stopper 50B does not get in the way.
The engagement portion 36 of the lock piece 30 is provided with the cutout end surface 16a of the lid 8B.
It comes in contact with and starts rotating counterclockwise. This point is
The operation of the embodiment is the same.

ま持ち上げる（二つ目のアクション操作）。Therefore, while the head 66a of the operating piece 66 is being pushed by the index finger of the left hand (while one action operation is being continued), the left thumb is pressed against the lower surface of the knob portion 20B of the knob operating member 6B. Lift the knob operation member 6B as it is (second action operation).

(1) In order to move the knob operating member 6, first, it is necessary to release the locked state of the lock releasing operation piece 42, and then move the knob operating member 6 while maintaining the unlocked state of the lock releasing operation piece 42. is there. That is, according to the present invention, the pinching tip of the unlocking operation piece 42 is operated to rotate the unlocking operation piece 42, and the rear end thereof is locked by the locking piece 30.
While performing the first action operation so as not to interfere with the protruding contact portion 35, the second action operation is performed in which the knob portion 20 of the knob operating member 6 is then grasped and the knob operating member 6 is quickly slid. Because you need to
Even if the thief operates the picking operation member from the outside by using the gap between the door and the wire member, the picking operation member does not move so easily. Therefore, it is possible to reliably prevent the sickle piece before the lock from being unlocked. (2) The effects of the above (1) can be achieved by reasonably combining the respective members. (3) In the second or third embodiment, the lock release operation piece can be obtained by simply grasping the protruding tip of the knob operation member with two fingers of one hand (for example, the thumb and the index finger of the left hand). It can be operated (rotated or slid), and the pinching operation member can be slid with the protruding tip part being pinched as it is. Therefore, the operability is very good.
