The cylinder body 23 comes into contact with the engagement piece 56 from the inner side of the mounting cylinder portion 52c, and the cylinder body 23 contacts the engagement piece 56 in a direction that prevents the engagement state with the handle body 52 from being released. It is inserted and fixed to the operation handle 21 in contact therewith.

  By the way, the rotor 24 is inserted into the cylinder body 23 so as to be rotatable, and is inserted into the mounting hole 54 of the operation knob 53 so that the front end thereof faces the outer surface of the operation knob 53. 2 and the unlocked position shown in FIG. 2 and the lock rotated about 90 degrees from the unlocked position in the clockwise direction by the normal key 65 inserted in the key hole 64 provided in the rotor 24. The rotor 24 can be rotated between the unlocked position and the locked position. In the rotor 24, the rotation of the rotor 24 between the unlocked position and the locked position is allowed / blocked to the cylinder body 23 by inserting the regular key 65 into the key hole 64. There are provided tumblers 66 that are switched by engaging and disengaging.

  A part of the outer surface of the rotor 24 is exposed between the handle main body 52 and the operation knob 53, and a connecting member 27 having one end opposed to the outer surface of the exposed portion of the rotor 24 is interposed between the rotor 24 and the slide member 26. Be dressed.

  When the rotor 24 is in the unlocked position (position shown in FIG. 9), the connecting member 27 locks the slide member 26 when the operating handle 21 is rotated to the open side as shown in FIG. The rotating force of the rotor 24 that rotates together with the operation handle 21 is transmitted to the slide member 26 so as to slide to the unlocking operation position side, but when the rotor 24 is in the locked position (position shown in FIG. 11), It serves to block power transmission between the slide member 26 and the rotor 24.

  The connecting member 27 is supported on the base member 20 so as to be rotatable about the same axis as the rotation axis of the operation handle 21, and the operation handle 21 is supported on the base member 20 so as to be rotatable. The connecting member 27 is rotatably supported on the second support shaft 51.

  On the outer surface of the rotor 24 at a portion where one end of the connecting member 27 faces, a drive contact surface 67 that comes into contact with one end of the connecting member 27 when the rotor 24 is in the unlocked position, and the rotor 24 is locked. An escape recess 68 is provided to avoid contact with one end of the connecting member 27 when in position.

  Further, the other end of the connecting member 27 is arranged to face one end of the slide member 26. As shown in FIGS. 9 and 11, the base member is in the state where the slide member 26 is in the lock operating position. 20 is arranged opposite to one end of the slide member 26 so as to be sandwiched between the restriction portion 69 provided at 20 and the spring contact portion 40 at one end of the slide member 26.

  Thus, when the rotor 24 is in the unlocked position, as shown in FIG. 9, the driving contact surface 67 of the rotor 24 is in a position corresponding to one end of the connecting member 27, and one end of the connecting member 27 is in the driving contact. In this state, when the operation handle 21 is opened, the connecting member 27 rotates together with the rotor 24 of the cylinder lock 22 as shown in FIG. 10, and the slide member 26 is moved from the lock operation position. A force for sliding toward the unlocking operation position is transmitted from the connecting member 27 to the sliding member 26. As a result, the slide member 26 slides to an unlocking operation position in which the engaging protrusion 39 is moved from a position engageable with the latch 32 as shown in FIGS. 4 and 5. In this state, The latch 32 is rotated to the side where the engagement with the striker 31 is released by the spring force of the spring 34, and the lock mechanism 25 is unlocked.

  At this time, when the operating handle 21 is returned to the closed position by the spring force of the torsion spring 60 by releasing the hand from the operating handle 21, the slide member 26 is returned from the unlocked operating position to the locked operating position by the spring force of the spring 35. The latch 32 has already returned to the unlocking operation position side, but the slide member 26 does not return to the locking operation position when the engaging protrusion 39 abuts against the side surface of the latch 32. Thus, when the latch 32 is rotated by engagement with the striker 31 by returning the lid 17 to the closed position side, the slide member 26 engages the engagement protrusion 39 with the latch 32 and locks the lock mechanism 25. Therefore, it will return to the lock operating position.

  When the rotor 24 is in the locked position, as shown in FIG. 11, the relief recess 68 of the rotor 24 is in a position corresponding to one end of the connecting member 27. In this state, as shown in FIG. When the opening operation is performed, even if the rotor 24 rotates together with the operation handle 21, one end of the connecting member 27 only enters the escape recess 55, and the connecting member 27 remains stationary and the slide member 26 in the lock operating position. And the connecting member 27 remains stationary so as to cut off the power transmission between the rotors 24.

  Next, the operation of this embodiment will be described. When the striker 31 is engaged with the latch 32, the lock mechanism 25 abuts against the striker 31 and urges the striker 31 to the side where the striker 31 is detached from the latch 32. A plate spring 42 disposed on the lock body 30 side, and one end of the plate spring 42 is engaged with the lock body 30 and the one end of the plate spring 42 is disengaged from the lock body 30. A pressing portion 48 that abuts against the intermediate portion of the leaf spring 42 so as to prevent the leaf spring 42 from being displaced to the side is provided on the base member 20.

  Accordingly, when the lock body 30 is attached to the base member 20 with one end of the leaf spring 42 engaged with the lock body 30, the pressing portion 48 of the base member 20 abuts against the intermediate portion of the leaf spring 42, thereby causing the leaf spring 42. Is fixed to the lock body 30 side, and the plate spring 42 can be easily fixed to the lock body 30 side without requiring a complicated operation such as caulking and coupling.

  The operation handle 21 is formed by mounting an operation knob 53 on a handle main body 52 that is rotatably supported by the base member 20 so as to cover the front surface of the handle main body 52. An engagement piece 56 that is detachably engaged with the support arm portion 52 b of the handle body 52 is provided, and the cylinder body 23 of the cylinder lock 22 is attached to the engagement piece 56 that is engaged with the handle body 52. The contact with the main body 52 is abutted in a direction to prevent the engagement state from being released, and the operation handle 21 is inserted and fixed.

  Therefore, when the operation knob 53 is engaged with the handle body 52 and the operation handle 21 is configured, when the cylinder body 23 of the cylinder lock 22 is inserted and fixed to the operation handle 21, the cylinder body 23 is engaged with the operation knob 53. Since the operation of the engagement piece 56 in contact with the piece 56 and the engagement state with the handle main body 52 being released is prevented, the operation knob 53 and the handle main body 52 are also engaged by the operation of the operation knob 53. The state will be reliably maintained.
