As a result, the stopper plate 59 is configured to move the external lock display unit 57 in the circumferential direction via the pin 58. Further, a small hole 63b is formed at an intermediate portion between the first notch groove 62a and the coupling hole 60 in the stopper plate 59, and a connecting pin 64 is attached to the small hole 63b.

  Here, FIG. 13 is a broken rear view for explaining the mutual relationship between the stopper plate 59 and the lock lever 10. As shown in the figure, the stopper plate 59 on the second position side is locked in the second notch groove 62b by the stopper pin 30 of the lock lever 10 in the open position. In this state, one line segment L1 connecting the rotation center CK of the key rotor 44 and the center CS of the stopper pin 30 and the other line connecting the center CS of the stopper pin 30 and the rotation center CN of the internal knob 32. The minute L2 is set to form an obtuse angle α2. On the other hand, as shown in FIG. 15A, the stopper plate 59 in the first position locks the stopper pin 30 of the lock lever 10 in the closed position with the first notch groove 62a. Even in this state, one line segment L1 and the other line segment L2 are set to form an obtuse angle α1.

  A guide plate 51 that is longer than the plate 59 is disposed behind the stopper plate 59. The guide plate 51 has an annular portion 51a having an oval shape at an intermediate portion, and the cylindrical portion 54a of the key rotor 44 is inserted into the annular portion 51a. A guide pin 65 (guide portion) that can be engaged with the guide wall 34b of the internal knob 32 is provided at one end portion of the guide plate 51 so as to protrude rearward. The other end portion of the guide plate 51 is swingably supported by a shaft member 48c provided on the support portion 48b. A long hole 66 is formed in an intermediate portion of the guide plate 51 between the guide pin 65 and the annular portion 51 a, and the connecting pin 64 is inserted through the long hole 66. Thus, the guide plate 51 swings with the stopper plate 59 by the connecting pin 64 with the lower end supported by the shaft member 48c as a swing fulcrum.

Here, as shown in FIG. 15A, when the stopper plate 59 is swung together with the guide plate 51 to the first position via the connecting pin 64, the first notch groove 62 a of the stopper plate 59 serves as the lock lever 10. The stopper pin 30 is locked, and the guide pin 65 of the guide plate 51 is configured to be in a locked state in which the stopper pin 30 is in contact with the guide wall 34b of the internal knob 32. In the locked state, the guide pin 65 and the guide wall 34b may be configured to be close to each other.
Further, as shown in FIG. 15B, the first play angle θ1 described above is such that the guide wall 34b is guided by the guide pin 65 by the turning operation of the internal knob 32 in a state where the lock lever 10 is maintained at the closed position. When the guide plate 51 swings with the stopper plate 59, the first notch groove 62a is set to be disengaged from the stopper pin 30 (that is, the locked state is released).

  FIG. 7 shows a cross-sectional view of the lock device 1. As shown in FIG. 7, the connecting pin 64 extends between the guide plate 51 and the stopper plate 59 and extends rearward. An in-compartment lock knob 68 is provided at the rear of the connecting pin 64. The internal lock knob 68 extends in the swinging direction of the stopper plate 59 (or the guide plate 51) at the front end portion of the grip portion 68b having a hole portion 68a in which the connecting pin 64 can be accommodated. The left and right pair of flange portions 68c are integrally formed. As shown in FIG. 4, the collar portion 68c is provided with an in-house main locking display portion 69 located at both left and right end portions thereof. The internal lock display unit 69 has, for example, display portions of two different colors (red R and blue B), the right side (left side in FIG. 4) is blue B and the left side is red R. .

  As shown in FIG. 5, a lock knob opening 70 that is gently curved along the moving direction of the internal lock knob 68 is formed at an intermediate portion of the rear wall portion 4 b of the cover 4. The holding portion 68b of the internal lock knob 68 is disposed so as to protrude rearward. In addition, an inner cover 71 that accommodates the front lock knob 68 and the front part of the inner knob 32 is disposed on the front side of the rear wall portion 4 b of the cover 4.

  The inner cover 71 has a circular notch 71a that exposes the flange 33 and the gripping portion 35 of the internal knob 32 in the upper half, and the gripping portion 68b of the internal lock knob 68 is exposed below the circular cover 71a. It has a curved cutout portion 71b to be formed, and forms a bottle opener as a whole. The lock knob opening 70 and the notch 71b correspond to the internal lock display window portion 74, and are configured such that red R and blue B of the display portion 69 alternatively appear from the window 74. Yes. Further, in the inner cover 71, an annular rib 72 that rotatably holds the outer periphery of the large-diameter portion 34 of the internal knob 32 is formed at the peripheral portion of the cutout portion 71a, and at the peripheral portion of the cutout portion 71b. The guide recess 71g that guides the internal lock knob 68 so as to be reciprocally movable is formed. A curved portion 72 a is formed at the lower portion of the annular rib 72 along the movement locus of the guide pin 65. The inner cover 71 is provided with three screw holes 71c to 71e and one boss 71f that project outside the annular rib 72. The inner cover 71 is inserted into the bosses 73a to 73c (see FIG. 4) of the main body case 3 by screws (not shown) inserted through the screw holes 71c to 71e, respectively. Fixed. On the other hand, the screw 76 (see FIG. 1B) screwed into the boss portion 71f of the inner cover 71 does not straddle the rotation range of the lock lever 10 (not shown). The inner cover 71 is fixed to the cover 4.

  As shown in FIGS. 4 and 7, a spring receiving portion 77a is provided on the rear surface of the main body case 3 so as to be located at the rear end portion of the extending piece portion 61a. A leaf spring 77, which is an urging member, is attached and fixed to the spring receiving portion 77a by a screw 78. As shown in FIG. 2, the leaf spring 77 has an inverted “h” shape, and biases the stopper plate 59 together with the guide plate 51 to the first position side or the second position side via the connecting pin 64. Thus, it can be surely shifted to the state of the final lock or the temporary lock described later, and functions as a moderation imparting means for imparting a moderation feeling when operating the internal lock knob 68 and the key rotor 44.

  Next, the operation of the lock device 1 configured as described above will be described with reference to FIGS. Here, FIGS. 12 (a), 12 (b), 14 (a), (b), and 15 (a) are for explaining the unlocked state, the temporary locked state, and the fully locked state, respectively. It is a fracture | rupture back view which abbreviate | omits and shows an internal structure partially. FIG. 9 is a rear view of the main part for explaining the transition operation between the temporary locking and the main locking, and FIG. 10 is a state transition diagram between the unlocking, the temporary locking and the main locking. Show. In the lock device 1 of the present invention, mutual state transitions between unlocking, temporary locking, and main locking are performed from the outside (indicated by a solid line in FIG. 10) and from the inside. (Indicated by a broken line in FIG. 10).

  First, the locking method from the outside of the warehouse will be described. In the unlocked state, as shown in FIGS. 1 (a) and 6, the lock lever 10 is in an upward open position where the blue B display portion 16 is viewed from the outside temporary lock display window portion 22a. At the open position, the moderation means 24 is held so as not to rotate together with the outside knob 20. In this state, the lock lever 10 is disengaged from the counterpart member of the sliding door 13, in this case, the garage main body (not shown), so that the sliding door 13 can be freely opened and closed. Further, the internal knob 32 has a position where the ball 36c fits into the moderation hole 29a with respect to the lock lever 10 when the internal unlocking is performed by the internal knob 32 (see FIG. 12A). When the most recent unlocking is performed by the outside knob 20, the ball 36c is held at the position where the ball 36c is fitted in the moderation hole 29b with respect to the lock lever 10 (see FIG. 12B). Is in a state. On the other hand, the key rotor 44 is in a neutral position, and when nothing is inserted into the key insertion hole 44a, each tumbler 52 projects from the tumbler arrangement groove 44d into the tumbler engagement groove 46a of the rotor case 45. . The stopper plate 59 and the guide plate 51 are urged to the second position side by a leaf spring 77, and the blue B display portion 57 is peeking from the outside lock display window portion 42 ( FIG. 9 (a)). Therefore, in this unlocked state, even if the key K is inserted into the key insertion hole 44a, the stopper plate 59 is locked by the stopper pin 30 in the second notch groove 62b, so that the key rotor 44 is unlocked. This locking by the turning operation is prevented (see FIG. 13).

  In this unlocked state, when the user rotates the outside knob 20 in the counterclockwise direction (arrow D1 direction) in FIG. 1A, the lock lever 10 is integrated with the outside knob 20 by the arrow. It turns to D1 direction, and it will be in the state of the side which turned 90 degree | times from the open position to the closed position. At this time, the hook portion 10a of the lock lever 10 is locked to the garage main body, and the outside knob 20 and thus the lock lever 10 are held in the closed position by the moderation means 24, and the outside temporary lock display window portion 22a. From the state shown in FIG. 11A, the red R display unit 16 is in a temporary locking state. Further, as the lock lever 10 is rotated, the stopper pin 30 is moved away from the second notch groove 62b of the stopper plate 59, thereby allowing the stopper plate 59 to move and the key rotor 44 to be rotated. . Further, as the outside knob 20 rotates, the inside knob 32 is passively moved in the direction of the arrow D1 via the coupling protrusion 21b, so that the moderation hole 29a is moved with respect to the lock lever 10. While being held at a position where the ball 36c is fitted (see FIG. 14B), the escape portion 34a and the guide wall 34b of the internal knob 32 are positioned so as to allow the guide plate 51 to move.

In the temporarily locked state shown in FIG. 14B, the closed state of the sliding door 13 is restricted by the lock lever 10. In this temporary locking state, when the outside knob 20 is rotated in the direction of the arrow D2, the unlocking state shown in FIGS. 1 and 12B is restored.
Next, the main locking from the outside of the warehouse using the regular key K will be described. As described above, the main locking is prevented by the engagement of the stopper plate 59 and the stopper pin 30 in the unlocked state, and thus is performed in the temporary locked state.

  When the key K is inserted into the key insertion hole 44a, each tumbler 52 is moved by the key K so as to be accommodated in the tumbler arrangement groove 44d against the urging force of the spring. Then, the key K is rotated in the direction of the arrow D3 in FIG. 1A to rotate the key rotor 44 from the neutral position to the locked position. By the rotation of the key rotor 44, the stopper plate 59 swings from the second position to the first position side together with the guide plate 51 via the connecting pin 64. As shown in FIG. 15B, during this swinging, the guide pin 65 of the guide plate 51 moves while abutting against the guide wall 34b of the internal knob 32, so that the internal knob 32 is moved to the first play angle. It is rotated in the direction of arrow D1 by θ1. Then, as the stopper plate 59 swings to the first position, the display portion 57 moves in the circumferential direction via the pin 58, and the red color R is seen through the outside lock display window portion 42 (FIG. 9B). In addition, the first notch groove 62a of the stopper plate 59 is in a locked state in which the stopper pin 30 of the lock lever 10 is locked (see FIG. 15A). Further, when the stopper plate 59 and the guide plate 51 swing to the first position side, a feeling of moderation is imparted by the leaf spring 77 and held at the first position. When the turning operation force of the key K is released in this state, the key rotor 44 has the second play angle θ2 with respect to the stopper plate 59 and is urged by the torsion coil spring 53 in the direction of arrow D4 in FIG. Therefore, the stopper plate 59 returns to the neutral position in a state where the first position of the stopper plate 59 (and the display of red R from the outside lock display window portion 42) is maintained (see FIG. 9C).

  FIG. 11 shows a state in which the key K is pulled out from the key insertion hole 44a after the above-described locking, and the key rotor 44 has each tumbler 52 (see FIG. 3) in the tumbler engaging groove 46a of the rotor case 45. And the rotation to the unlocking position is restricted. Further, the closed state of the sliding door 13 is restricted by the lock lever 10, and the outside knob 20 is prevented from rotating by the stopper plate 59 preventing the rotation of the lock lever 10. (See FIG. 15A).

  When releasing this locked state from the outside, the key K is inserted into the key insertion hole 44a and moved so that each tumbler 52 is accommodated in the tumbler arrangement groove 44d. Then, the key K is rotated in the direction of arrow D4 in FIG. 1A to rotate the key rotor 44 from the neutral position to the unlocked position. The rotation of the key rotor 44 causes the stopper plate 59 to swing from the first position to the second position side together with the guide plate 51 via the connecting pin 64, so that the first notch groove 62a of the stopper plate 59 is locked. The engagement of the lever 10 with the stopper pin 30 is released, and the guide pin 65 of the guide plate 51 is separated from the guide wall 34b of the internal knob 32 (see FIG. 14A). As a result, the turning operation of the outside knob 20 is permitted, the red display portion 16 is viewed from the outside temporary lock display window portion 22a, and the blue B display portion 57 is seen from the outside lock display window portion 42. It will be in the state of the said temporary locking to peep. When the rotational operation force of the key K is released in this state, the key rotor 44 is urged by the torsion coil spring 53 in the direction of the arrow D3 in FIG. In a state where the display of blue B from the outer book lock display window 42 is maintained, it returns to the neutral position (see FIG. 9A). Accordingly, the user shifts from the temporarily locked state to the unlocked state by rotating the outside knob 20 (that is, unlocks the lock lever 10 with respect to the garage body), and the sliding door. 13 can be freely opened and closed.

Next, a locking method from the inner side and a releasing method thereof will be described.
This locking from the inside of the cabinet is particularly useful when the lock device 1 is applied to a sliding door different from the shutter in a garage attached to a house, for example. In this case, when the user rotates the internal knob 32 in the arrow D1 direction in FIG. 1B in the unlocked state, the lock lever 10 moves from the open position to the closed position in the arrow D1 direction. It will be in the sideways state rotated 90 degrees. At this time, similarly to the turning operation of the outside knob 20, the lock lever 10 is locked temporarily with respect to the garage main body, and the stopper plate 59 and the guide plate 51 are allowed to swing. However, since the internal knob 32 is directly operated by the user, the internal knob 32 is held at a position where the ball 36c is fitted in the moderation hole 29b with respect to the lock lever 10 (see FIG. 14A).

  In the temporarily locked state shown in FIG. 14A, the closed state of the sliding door 13 is restricted by the lock lever 10. In this temporary locking state, when the internal knob 32 is rotated in the direction of arrow D2, the unlocked state shown in FIGS. 1 and 12 (a) is restored.

  Next, a description will be given of the main locking from the inner side by the inner lock knob 68. This locking is also performed through a temporary locking state. That is, when the internal lock knob 68 is shifted in the direction of arrow D5 in the temporarily locked state, the stopper plate 59 swings from the second position to the first position side together with the guide plate 51 via the connecting pin 64. By this swinging, the first notch groove 62a of the stopper plate 59 engages the stopper pin 30 of the lock lever 10, and the guide pin 65 of the guide plate 51 contacts the guide wall 34b of the internal knob 32. Then (see FIG. 15A), the red R display portion 69 can be seen through the internal lock display window portion 74 (see FIG. 11B). Further, during the shift operation, the internal lock knob 68 is given a sense of moderation by the leaf spring 77 via the connecting pin 64 and is held on the left side (first position side) in FIG. On the other hand, when the stopper plate 59 swings, the key rotor 44 is maintained in the neutral position because it has the second play angle θ2 with respect to the stopper plate 59, and the red R is viewed from the outside lock display window 42. (See FIG. 9C).

  Thus, as shown in FIG. 11, without the key K, it is possible to shift to the above-described locked state by the operation from the inside of the storage lock knob 68, and in this locked state, the storage from outside the storage is possible. The outer knob 20 cannot be rotated (see FIG. 15A).

  In this locked state, when the internal lock knob 68 is shifted in the direction of arrow D6, the temporary locking state is restored. That is, when the internal lock knob 68 is shifted in the direction of arrow D6, the stopper plate 59 swings together with the guide plate 51 from the first position to the second position via the connecting pin 64. By this swinging, the first notch groove 62a of the stopper plate 59 releases the engagement with the stopper pin 30 of the lock lever 10, and the guide pin 65 of the guide plate 51 is separated from the guide wall 34b of the internal knob 32 ( 14 (a)), the blue B display portion 69 looks into the temporary locking state through the internal lock display window portion 74 in the warehouse. Accordingly, the user can freely open and close the sliding door 13 by moving the unlocking knob 32 from the temporarily locked state to the unlocked state.

  As shown in FIG. 10, in the lock lock device 1 of the present invention, it is possible to shift directly from the locked state to the unlocked state by operating the internal knob 32. Specifically, when the internal knob 32 is rotated in the direction of arrow D2 in the locked state shown in FIG. 15A, the guide wall 34b of the internal knob 32 presses the guide pin 65 of the guide plate 51. Rotate while. At this time, as shown in FIG. 15 (b), the inner knob 32 is rotated by the first play angle θ1 while the closed position of the lock lever 10 is maintained, so that the guide wall 34b is guided by the guide wall 34b. The first notch groove 62 a of the stopper plate 59 is removed from the stopper pin 30 by pressing the pin 65. As the internal knob 32 rotates, the guide wall 34b presses the guide pin 65 to swing the guide plate 51 and the stopper plate 59 to the second position side, and locks via the coupling protrusion 21b. The lever 10 is rotated from the closed position to the open position (see FIG. 12A). Thus, the sliding lever 13 can be opened from the inside of the warehouse because the lock lever 10 is held so as not to rotate together with the outside knob 20 by the moderation applying means 24 in the upward state in which the lock lever 10 is rotated to the open position. In addition, even when the state is shifted directly from the locked state to the unlocked state only by the operation of the internal knob 32, the state is shifted to the unlocked state via the temporary lock state by the internal lock knob 68 and the internal knob 32. In this case, the state shown in FIG. 1 and FIG.

  According to the above configuration, since the first play angle θ1 is provided between the inner knob 32 and the outer knob 32 (lock lever 10), the unlocking operation from the outside can be performed by the stopper plate 59 in this locked state. While blocking, the guide plate is swung to the second position side together with the stopper plate 59 (so as to release the lock) only by rotating the inner knob 32 from the inner side by the first play angle θ1. Can be made. Further, when the internal knob 32 is rotated, the neutral position of the key rotor 44 is maintained by the second play angle θ2 between the key rotor 44 and the stopper plate 59, so that the locked state is not used without using the key K. Can be released, and the lock lever 10 can be rotated from the closed position to the open position as the internal knob 32 rotates. As described above, the closed state of the sliding door 13 can be easily released from the inside of the warehouse by the inside knob 32 while ensuring safety in the crime prevention surface, and it can be made easy to use. Therefore, when the lock device 1 is applied to, for example, a sliding door such as a storeroom having an internal space in which a person can go in and out, the above-described problem of trapping a person can be solved.

  The lock device 1 includes an internal lock knob 68 disposed on the rear surface side of the lock case 2 so as to be movable. In the temporary locking state, the key rotor 44 can be turned to the fully locked position or the internal lock knob 68 can be moved. The stopper plate 59 is swung from the second position to the first position together with the guide plate 51 by a moving operation via the connecting pin 64 so as to be in the locked state. According to this configuration, when the lock device 1 is applied to a sliding door different from the shutter in a garage attached to a house, for example, the following effects are obtained.

  That is, unlike the present invention, in a conventional lock device that cannot be operated from the inside of the storage, for example, when entering the storage from the sliding door and taking out the car from the shutter, the storage device moves to the sliding door again. After locking from the outside, it will be troublesome because it will go around the outside and return to the car. In addition, in the conventional lock device, for example, when returning home, after locking in the garage, even if you want to go out of the warehouse using the sliding door, you can not unlock it from the inside of the warehouse, so it also moves to the shutter side and moves outside the warehouse. I will go home. On the other hand, according to the lock device 1 of the present invention, when going out or going home, the lock on the sliding door 13 is locked by the lock knob 68 in the cabinet, and the lock is released by the knob 32 in the cabinet, and the key K is pressed from the inside of the cabinet. Since it can be performed without using it, it is useful in practice and the convenience of the garage can also be enhanced.

  Further, in the lock device described in Patent Document 1 described above, the state in which the knob operation member is on the release position side (ie, the closed state of the sliding door by the lock lever is released), for example, because the user forgets to temporarily lock. ), An erroneous operation for locking the cylinder lock is likely to occur. On the other hand, according to the lock device 1 of the present invention, the stopper plate 59 has, on the second position side, the second notch groove 62b that is locked by the stopper pin 30 of the lock lever 10 in the open position. Then, the engagement between the stopper pin 30 and the second notch groove 62b prevents the key rotor 44 from rotating to the final locking position, so that the main locking is performed before the temporary locking. It is possible to prevent erroneous operation. Since the key rotor 44 has a second play angle θ2 with respect to the stopper plate 59 and is biased to the neutral position by the torsion coil spring 53, the key rotor 44 is in the state of being locked in the locked position. The lock lever 10 is not moved to the open position by the knob 32. In other words, since the lock lever 10 is not moved to the open position even though the key rotor 44 in the locked position is in the locked position, misrecognition or misoperation regarding locking by the user is made as much as possible. It can be prevented, and the security in terms of crime prevention can be improved as a whole.

  In a state where the first notch groove 62a engages the stopper pin 30 at the first position of the stopper plate 59, the one line segment L1 and the other line segment L2 viewed from the direction of the rotation center axis L0 are By setting so that the obtuse angle α1 is formed, the lock lever 10 is reliably prevented from rotating to the open position. According to this, it is possible to prevent opening of the lock lever 10 in the locked state, and it is possible to further improve the safety on the crime prevention surface. Further, in a state where the second notch groove 62b engages the stopper pin 30 at the second position of the stopper plate 59, by setting the one line segment L1 and the other line segment L2 to form an obtuse angle α2, By reliably preventing the key rotor 44 from turning to the main locking position, it is possible to reliably prevent an erroneous operation of performing the main locking before the temporary locking.

  The lock case 2 accommodates the lock lever 10, the cylinder lock 43, the torsion coil spring 53, the stopper plate 59, the guide plate 51, the external knob 20, the internal knob 32, and the internal lock knob 68, and the side wall portion of the lock case 2 4b is formed with a notch 11 for projecting the tip of the lock lever 10, and the outside knob 20 is provided with a gripping part 23 protruding forward from the front surface of the lock case 2, and the inside knob 32 and the inside lock knob 68 are provided with gripping portions 35 and 68a that protrude rearward from the rear surface of the lock case 2, respectively. Therefore, the lock case 2 can protect the internal movable part from being touched by the user's hand, and the gripping portions 23, 35, 68a of the respective operation members 20, 32, 68 can be used for the rotation. The moving operation can be performed safely and easily. Further, the lock device 1 is excellent in versatility because each member 10, 20, 32, 43, 51, 53, 59, 68 constituting the lock device 1 is unitized by being provided in the lock case 2. At the same time, the assembly workability for the sliding door 13 and the like can be improved.

The inside lock knob 68c of the inside lock knob 68 is provided with a red R and blue B internal lock display 69, and the red R and blue B are used for the internal lock display window 74 during temporary lock and full lock. It was configured to appear alternatively. For this reason, the state of temporary locking and the state of this locking can be easily recognized in a warehouse.
A light guide member 38 penetrating the outer knob 20, the lock lever 10, and the inner knob 32 is provided along the rotation center axis L0 of the outer knob 20. The light guide member 38 can guide external light into the interior and illuminate the interior of the interior from the center of the interior knob 32, so that the visibility of the interior knob 32 can be improved.

The red R and blue B outside temporary locking display portions 16 are arranged so as to be continuous with the rotation direction of the outside knob 20, and the red R and blue B are at the open position and the closed position of the lock lever 10. It was comprised so that it might alternatively appear from the outside temporary lock display window 22. For this reason, the unlocked state and the temporary locked state can be easily recognized outside the warehouse.
Further, the red R and blue B external lock display portions 57 are arranged so as to be continuous in the swinging direction of the stopper plate 59 or the guide plate 51, and the red R and blue colors are temporarily locked and locked. B is configured to alternatively appear from the outside lock display window portion 42. For this reason, the state of temporary locking and the state of this locking can be easily recognized outside a warehouse.

The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
The lock device 1 of the present invention is not limited to a garage or a storeroom, and can be applied to all structures having an internal space where people can go in and out. Moreover, the attachment aspect of the lock apparatus 1 with respect to the sliding door 13 grade | etc., Is not limited to the said embodiment, For example, you may attach the lock apparatus 1 to the sliding door 13 upside down.

Each of the moderation imparting means 24 and 36 and the leaf spring 77 has a function of maintaining the position of the corresponding member as described above. However, each of the moderation imparting means 24 and 36 and the leaf spring 77 is not necessarily provided. Depending on the form, for example, only the moderation means 24 may be omitted or the like may be appropriately changed.
The outside knob 20, the lock lever 10, and the inside knob 32 are connected to each other by the connecting protrusion 21b of the outside knob 20, but this connecting means is not limited to the connecting protrusion 21b. That is, in this coupling means, the outside knob 20 and the lock lever 10 rotate integrally, and the inside knob 32 is coupled to the outside knob 20 or the lock lever 10 with the first play angle θ1. What is necessary is just to be comprised.
