The case where it is in a position where it can contact the protrusion 12 of 13 is shown. In this state, when the handle 13 is rotated against the elastic force of the handle spring 32 and with the shaft 30 as the center and pulled outward, the receiving portion 48 is moved downward by the protrusion 12. Therefore, the stopper 17 is moved from the locking position shown by the solid line in FIG. 9 and in contact with the back surface 15e of the latch 15 to the lower non-locking position. Therefore, the engagement between the stopper 17 and the latch 15 is released, and the latch spring 16 causes the latch 15 to move to the ninth position.
The door is rotated counterclockwise to the door opening position shown by the dotted line in the figure, and the locking portion 15d abuts the contact surface 11a of the frame 11 to open the door. When the door is open, the upper end 17b of the stopper 17 is the latch 15
The stopper 17 is elastically pressed upward against the latch 15 by the end portion 32b of the handle spring 32 while contacting the lower surface 15f of the locking portion 15d. Therefore, the latch 15 is held in the unlocked position.

When the latch 15 contacts a striker (not shown), the latch 15 is rotated clockwise in FIG. Therefore, the latch 15 is returned to the closed position, the stopper 17 is moved upward by the end 32b of the handle spring 32, and is returned to the state shown in FIG.

When the key is inserted into the key cylinder 14 and rotated to the locked position, the stopper 17 is moved to the right in FIGS. 5 and 6 by the rotation of the protrusion 43. Therefore, handle spring 32
End portion 32b is moved from the second notch portion 47 to the first notch portion 46. Therefore, the receiving portion 48 of the stopper 17 is the handle
The notch 49 is moved to a position away from the protrusion 12 and the notch 49 is moved to a position facing the protrusion 12. Even if the handle 13 is rotated in this state, the protrusion 12 comes into contact with the notch 49 and the stopper 17 cannot be moved sufficiently downward. Therefore, the stopper 17 and the locking portion 15d of the latch 15 are not disengaged from each other, so that the latch 15 is held at the locking position shown in FIG. When the key is rotated to the unlocked position together with the key cylinder 14, the rotation of the protrusion 43 causes the stopper 17 to move to the fifth position.
It is moved to the left in FIGS. 6 and 6 and returned to the state shown. Therefore, the end portion 32b of the handle spring 32 is relatively moved from the first cutout portion 46 to the second cutout portion 47.
