  The housing main body 21 extends in the front-rear direction of the door (left-right direction in FIG. 1) and opens in the door inner direction (vertical upward direction in FIG. 1). It has a dish-like second case portion 21b that is orthogonal to the case portion 21a and opens in the door rear side direction (right direction in FIG. 1). As shown in FIG. 3, a cover 31 is attached to the opening of the first case portion 21a, and a sub-base housing 41 is attached to the opening of the second case portion 21b. Accordingly, the opening of the first case portion 21 a is closed by the cover 31, and the opening of the second case portion 21 b is closed by the sub base housing 41. The sub-base housing 41 also covers the rear opening of the cover 31.

  The housing body unit 20 includes an open lever 22, a torsion spring 23, an active lever 24, a torsion spring 25, an open link 26, an electric motor 27, a wheel gear 28, and an idle lever 29 provided on the housing body 21.

  As shown mainly in FIG. 3, the open lever 22 is rotatably supported by a stepped boss 21 c that is a support convex portion integrally provided on the inner wall surface of the second case portion 21 b of the housing body 21. Yes. The stepped boss 21c has a large-diameter portion 21c1, a small-diameter portion 21c2, and an engagement pin 21c3 that are coaxially formed in order from the root toward the tip (see FIG. 13). The through hole 22a of the open lever 22 is fitted in the small diameter portion 21c2. Thereby, the open lever 22 can rotate the stepped boss 21c about the rotation axis (fulcrum). The height of the small diameter portion 21c2 is set to a value slightly larger than the thickness of the open lever 22, and the open lever 22 is sandwiched between the step between the small diameter portion 21c2 and the large diameter portion 21c1 and a sub base plate 42 described later. And held rotatably (clamped).

  The open lever 22 has a first arm 22b extending in one direction from the through hole 22a and a second arm 22c extending from the through hole 22a in a substantially opposite direction to the first arm 22b. An outside handle (not shown) is coupled to a coupling hole 22b2 of a coupling portion 22b1 formed at the tip (one end) of the first arm 22b via a coupling member (such as a link). An engagement protrusion 22c1 and an abutting portion 22c2 are formed at the distal end portion (the other end portion) of the second arm 22c. The engagement protrusion 22c1 is engaged with an engagement hole 26a of the open link 26 described later. The abutting portion 22c2 is a portion in which an abutting portion 34b2 of an inside lever 34 described later is detachably abutted.

  The open lever 22 is urged by a torsion spring 23 disposed between the housing body 21 (second case portion 21 b) and the open lever 22. The torsion spring 23 is fitted to the large diameter portion 21c1 of the stepped boss 21c. One end 23 a of the torsion spring 23 is locked to a part 21 d of the inner peripheral wall surface of the second case portion 21 b, and the other end 23 b of the torsion spring 23 is locked to the second arm 22 c of the open lever 22. Thus, the open lever 22 is urged counterclockwise in FIG.

  Further, the first arm 22b of the open lever 22 biased in this way is in contact with a part (contact wall) 21e of the inner peripheral wall surface of the second case portion 21b, so that counterclockwise rotation is restricted. The open lever 22 is positioned and fixed at the position shown in FIG. 3 (temporary fixing position). Since the temporary fixing position is set outside the range in which the open lever 22 operates in the fully assembled state, there is no hindrance to the operation of the open lever 22 in the fully assembled state by the temporary fixing portion (described later). After the housing unit 10 and the sub base unit 40 are assembled and integrated, that is, in this assembled state, the contact portion 22b3 formed on the connecting portion 22b1 of the first arm 22b is not attached to the sub base plate 42. The first arm 22b is abutted against the provided rotation restricting portion 42e and the counterclockwise rotation is restricted, and the open lever 22 is positioned and fixed at a position (normal position) indicated by a solid line in FIG. ing.

  Therefore, the open lever 22 is urged by the torsion spring 23 and positioned at the normal position at the normal time when the outside handle is not opened. On the other hand, when the open lever 22 is operated to open the outside handle, one end of the open lever 22 (the tip of the first arm 22b) is pushed down so that the open lever 22 resists the urging force of the torsion spring 23. 3 is rotated clockwise in FIG. As a result, the other end of the open lever 22 (the tip of the second arm 22c) is pushed up, and the open link 26 is pushed up.

  The active lever 24 is rotatably supported by a stepped boss 21f that is integrally projected on the inner wall surface of the first case portion 21a of the housing body 21. The stepped boss 21f has a large-diameter portion (not shown) and a small-diameter portion 21f2 coaxially formed in order from the base toward the tip. The through hole 24a of the active lever 24 is fitted in the small diameter portion 21f2. Thereby, the active lever 24 can rotate the stepped boss 21f about the rotation axis (fulcrum). The height of the small diameter portion 21f2 is set to a value slightly larger than the thickness of the active lever 24, and the active lever 24 protrudes from the step between the small diameter portion 21f2 and the large diameter portion and the inner wall surface of the cover 31 described later. It is sandwiched between the upper end of the female boss 31f to which the small-diameter portion 21f2 is fitted and is rotatably held (clamped).

  The active lever 24 is different from the first arm 24b extending in one direction outside the first case portion 21a from the through hole 24a and from the first arm 24b toward the outside of the first case portion 21a from the through hole 24a. A second arm 24c extending in the direction, and a third arm 24d extending from the through hole 24a in the substantially opposite direction to the first and second arms 24b, 24c. A lock knob (not shown) provided on the inner side of the door is connected to a connection hole 24b1 formed at the tip of the first arm 24b via a connection member (cable or the like). When the lock knob is locked, the active lever 24 is rotated counterclockwise. Conversely, when the lock knob is unlocked, the active lever 24 is rotated clockwise.

  A contact portion 24c1 is formed at the tip of the second arm 24c. The abutment portion 24c1 is a pair of abutment walls 29b1 and 29b2 provided on the idle lever portion 29b of the idle lever 29 that is rotated by a rotation operation of a key cylinder to be described later. When the key cylinder is locked, the idle lever portion 29b is rotated clockwise and the active lever 24 is rotated counterclockwise. Conversely, when the key cylinder is unlocked, the idle lever portion 29b is rotated counterclockwise and the active lever 24 is rotated clockwise.

  The third arm 24d is formed in a fan shape, and the outer periphery is formed in an arc shape centered on the axis of the through hole 24a. An engaging recess 24d1 is formed in the outer peripheral edge. The engaging recess 24d1 is configured to selectively engage the first and second engaging pins 28a and 28b provided on the wheel gear 28 that is rotated forward and backward by the electric motor 27. When the lock operation is performed by the electric motor 27, the wheel gear 28 is rotated clockwise and the active lever 24 is rotated counterclockwise. Conversely, when the unlocking operation is performed by the electric motor 27, the wheel gear 28 is rotated counterclockwise, and the active lever 24 is rotated clockwise.

  A long hole 24d2 extending toward the through hole 24a is formed on one side of the third arm 24d. The long hole 24d2 is slidably engaged with an engagement pin 26b of the open link 26 described later.

  The third arm 24d is provided with first and second locking projections 24d3 and 24d4 between the outer peripheral edge portion and the through hole 24a. The first locking protrusion 24d3 abuts on a stop member 21g provided on the inner wall surface of the first case portion 21a and restricts the clockwise rotation of the active lever 24. The second locking protrusion 24d4 contacts the stop member 21g and restricts the counterclockwise rotation of the active lever 24.

  The active lever 24 is urged by a torsion spring 25 disposed between the housing body 21 (first case portion 21 a) and the active lever 24. One end 25a of the torsion spring 25 is locked in a locking hole 21h provided in the inner wall surface of the first case portion 21a, and the other end 25b of the torsion spring 25 is locked in the first arm 24b of the active lever 24. It is locked in the hole 24b2.

  When the active lever 24 is mainly in the unlock position shown in FIGS. 1 and 8, the active lever 24 is urged clockwise by a torsion spring 25. At this time, the active lever 24 is positioned and fixed at the unlocked position shown in FIG. 1, with the first locking projection 24d3 abutting against the stop member 21g to restrict clockwise rotation. When the active lever 24 is mainly in the locked position shown in FIGS. 10 and 11, the active lever 24 is urged counterclockwise by the torsion spring 25. At this time, the active lever 24 is positioned and fixed at the lock position shown in FIGS. 10 and 11 by the second locking projection 24d4 coming into contact with the stop member 21g and the counterclockwise rotation being restricted. .

  Therefore, the active lever 24 positioned and fixed at the unlock position shown in FIG. 1 is rotated counterclockwise when the lock knob and the key cylinder are locked or when the electric motor 27 is locked. It is positioned and fixed at the lock position shown in FIG. On the other hand, the active lever 24 positioned and fixed at the lock position is rotated clockwise when the lock knob and the key cylinder are unlocked or when the electric motor 27 is unlocked. Is fixed to the position.

  The open link 26 is formed in a substantially bar shape and is supported by the open lever 22 and the active lever 24 at two points. An engagement hole 26 a is formed at one end (lower end) of the open link 26. The engaging protrusion 22c1 of the open lever 22 is engaged with the engaging hole 26a. At the other end (upper end) of the open link 26, an engagement pin 26b is formed. The engagement pin 26b is slidably engaged with the long hole 24d2 of the active lever 24. The open link 26 is in a standing state (unlocked state) when the active lever 24 is located at the unlocked position shown in FIG. 1, and when the active lever 24 is located at the locked position shown in FIG. It is tilted (locked). The open link 26 is configured so that the operating force of the outside handle or the inside handle provided on the door cannot be transmitted to the pole 45 in the locked state, and the outside handle or the inside handle of the outside handle is in the unlocked state. The operation force can be transmitted to the pole 45.

  A contact portion 26 c is formed at the other end (upper end) of the open link 26. When the open link 26 is in the standing state, the contact portion 26c is moved upward to contact the contact portion 46a of the lift lever 46 to rotate the lift lever 46 (push up the contact portion 46a). is there. When the open link 26 is in a tilted state, the contact portion 26c does not contact the contact portion 46a of the lift lever 46 even if it is moved upward.

  The open link 26 is provided with one side surface 26d with which a cancel lever 32 described later comes into contact. The contact portion 32 b 1 of the cancel lever 32 is in contact with one side surface 26 d of the open link 26 by the urging force of the torsion spring 33. As a result, the open link 26 is pressed by the cancel lever 32 to the opposite side of the one side surface 26d (rightward in FIG. 1), so that the engagement hole 26a of the open link 26 rattles to the engagement protrusion 22c1 of the open lever 22. The engaging pin 26b of the open link 26 is engaged with the long hole 24d2 of the active lever 24 without rattling.

  A concave portion 26 e is provided on one side surface 26 d of the open link 26. As shown in FIG. 9, the concave portion 26 e is formed in a portion where the abutting portion 32 b 1 of the cancel lever 32 abuts in the opened state of the outside handle and the inside handle. That is, when the open link 26 is pushed up, the contact portion 32b1 of the cancel lever 32 moves (rotates) according to the shape of the one side surface 26d of the open link 26. In particular, when the concave portion 26e of the one side surface 26d reaches the contact portion 32b1, the cancel lever 32 rotates counterclockwise and the contact portion 32c1 of the cancel lever 32 is separated from the lift lever 46. Therefore, even if the open link 26 is pushed up, the contact portion 46a of the lift lever 46 pushed up by the open link 26 can be prevented from interfering with the contact portion 32c1 of the cancel lever 32.

  Further, the engagement hole 26a of the open link 26 is formed in a gourd shape, and a pair of protrusions 26a1 and 26a1 for holding the engagement protrusion 22c1 from both sides are formed, and the longitudinal direction of the engagement hole 26a is the length of the engagement protrusion 22c1. It is formed slightly larger than the width. Whether the open link 26 is tilted or standing, the gap between the engagement hole 26a and the engagement protrusion 22c1 can be suppressed as small as possible and the open link 26 can be held reliably.

  The electric motor 27 is attached to the inner wall surface of the first case portion 21 a of the housing body 21. The electric motor 27 includes a worm 27a on an output shaft, and a wheel gear 28 meshes with the worm 27a. The wheel gear 28 is rotatably supported by a support boss 21i formed integrally with the inner wall surface of the first case portion 21a. The support boss 21 i is fitted with a female boss 31 g protruding from the inner wall surface of the cover 31 so as to sandwich the wheel gear 28. An active lever 24 is disposed between the wheel gear 28 and the inner wall surface of the first case portion 21 a, and the wheel gear 28 is disposed so as to overlap the active lever 24.

  On one side surface of the wheel gear 28 (side surface facing the inner wall surface of the first case portion 21a), first and second engagement pins 28a and 28b are provided so as to project. Both the engagement pins 28a and 28b are arranged on the same straight line passing through the rotation center of the wheel gear 28 with a predetermined interval between the rotation centers. Either one of the engagement pins 28a and 28b abuts on the outer periphery of the third arm 24d, and the other faces the engagement recess 24d1 of the active lever 24.

  When the lock operation is performed by the electric motor 27, the electric motor 27 is driven, and the wheel gear 28 in the state shown in FIG. 1 is rotated clockwise. At this time, the first engagement pin 28a facing the engagement recess 24d1 enters and engages with the engagement recess 24d1, and the active lever 24 is rotated counterclockwise as the wheel gear 28 rotates. The When the second engagement pin 28b comes into contact with the outer periphery of the third arm 24d (the outer periphery on the right side of the engagement recess 24d1) and the first engagement pin 28a retracts from the engagement recess 24d1, the electric motor 27 is driven. The driving of the wheel gear 28 is stopped and the active lever 24 is positioned and fixed at the lock position. On the other hand, when the unlocking operation is performed by the electric motor 27, the wheel gear 28 is rotated counterclockwise by the operation opposite to the above-described locking operation, and the active lever 24 is rotated clockwise. Then, the wheel gear 28 is stopped at the position shown in FIG. 1, and the active lever 24 is positioned and fixed at the unlock position.

  As shown mainly in FIG. 3, the idle lever 29 is a cylindrical support portion 21 j erected from the inner wall of the first case portion 21 a of the housing body 21 toward the outside (the extending direction of the second case portion 21 b). It is attached to be able to rotate. The idle lever 29 includes a shaft portion 29a supported by the support portion 21j, an idle lever portion 29b formed integrally with one end of the shaft portion 29a, and a connecting lever formed integrally with the other end of the shaft portion 29a. It is comprised from the part 29c.

  The idle lever portion 29b is formed in a fan shape as shown in FIG. 1, and rotates around the same rotation axis as the rotation axis of the shaft portion 29a. A pair of contact walls 29b1 and 29b2 are formed at both ends of the idle lever portion 29b. A contact portion 24c1 formed on the second arm 24c of the active lever 24 is disposed between the contact walls 29b1 and 29b2 so as to be loosely fitted. The connecting lever portion 29c extends vertically downward in the drawing of FIG. 3 and rotates about the same rotation axis as the rotation axis of the shaft portion 29a. The distal end portion of the connecting lever portion 29c is connected to a key cylinder (not shown) attached to an outside handle provided outside the door via a connecting member (such as a link).

  When the key cylinder is locked, the connecting lever portion 29c is rotated clockwise, and the idle lever portion 29b in the state shown in FIG. 1 is rotated clockwise. At this time, the abutting wall 29b1 of the idle lever portion 29b abuts on the abutting portion 24c1 formed on the second arm 24c of the active lever 24, and the active lever 24 is counteracted as the idle lever portion 29b rotates. It is rotated clockwise. Then, the active lever 24 is positioned and fixed at the lock position. On the other hand, when the key cylinder is unlocked, the idle lever portion 29b is rotated counterclockwise by the reverse operation of the lock operation described above, and the active lever 24 is turned clockwise by the contact portion 29b2 of the idle lever portion 29b. It is turned around. Then, the active lever 24 is positioned and fixed at the unlock position (position shown in FIG. 1).

  As shown mainly in FIG. 2, the cover unit 30 includes a cancel lever 32, a torsion spring 33, and an inside lever 34 provided on the cover 31.

  The cancel lever 32 is rotatably supported by a mounting pin 31b fitted in a through hole of a support boss 31a provided on the inner wall surface of the cover 31. The cancel lever 32 is formed in a bent shape, and has a first arm 32b extending in one direction from a through hole 32a provided in a bent portion and a second arm 32c extending in the other direction. is doing. Abutting portions 32b1 and 32c1 are formed at the tip portions of the first and second arms 32b and 32c, respectively. The contact portions 32b1 and 32c1 are one contact end portion and the other contact end portion, respectively. The contact portion 32b1 is in contact with one side surface 26d of the open link 26. The contact portion 32c1 is detachably contacted with the contact portion 46a of the lift lever 46. The cancel lever 32 changes the open link 26 in the locked state to the unlocked state by applying an operating force from the pawl 45 constituting the hooking means to the open link 26.

  The cancel lever 32 is urged by a torsion spring 33 disposed between the cover 31 and the cancel lever 32. The torsion spring 33 is fitted to the support boss 31a. One end 33 a of the torsion spring 33 is engaged with an engaging pin 31 c erected on the inner wall surface of the cover 31, and the other end 33 b of the torsion spring 33 is engaged with an engaging projection 32 c 2 provided on the second arm 32 c of the cancel lever 32. It is locked to. Accordingly, the cancel lever 32 is urged clockwise in FIG. 2 (counterclockwise in FIG. 1), and the contact portion 32b1 of the first arm 32b of the cancel lever 32 is predetermined. It is biased in the direction (left direction in FIG. 2 and right direction in FIG. 1). Further, the abutting portion 32b1 always abuts against one side surface 26d of the open link 26 by the urging force of the torsion spring 33, and the abutting portion 32b1 always presses the one side surface 26d of the open link 26 in a predetermined direction. ing.

  The inside lever 34 is rotatably supported by a mounting pin 31e fitted in a through hole 31d provided on the inner wall surface of the cover 31. The inside lever 34 includes a through hole 34a and has an arm 34b extending in one direction from the through hole 34a. A connecting portion 34b1 and an abutting portion 34b2 are formed at the distal end portion and the intermediate portion of the arm 34b, respectively. An inside handle (not shown) provided on the inner side of the door is connected to the connecting portion 34b1 via a connecting member (such as a cable). The abutting portion 34b2 is a portion in which the abutting portion 22c2 of the open lever 22 is detachably abutted.

  The inside lever 34 is positioned at a normal position shown in FIG. 2 (indicated by a two-dot chain line in FIG. 1) by connection with the connecting member at a normal time when the inside handle is not opened. On the other hand, when the inside lever 34 is operated to open the inside handle, the inside lever 34 is rotated clockwise in FIG. 1 so that the contact portion 34b2 contacts the contact portion 22c2 of the open lever 22. Then, the tip of the second arm 22c of the open lever 22 is pushed up, and the open lever 22 is rotated clockwise in FIG. 3 against the urging force of the torsion spring 23. When the inside handle is closed, the open lever 22 and the inside lever 34 are returned to their original positions by the urging force of the torsion spring 23.

  As shown in FIGS. 5 and 6, the sub base unit 40 includes a sub base plate 42, a base plate 43, a latch 44, a pole 45, a lift lever 46, and a torsion spring 47 provided in the sub base housing 41.

  The sub base plate 42 and the base plate 43 are attached so as to sandwich the rear side wall 41a of the sub base housing 41 from the inside and the outside. The sub-base housing 41 is formed with a groove 41b through which a striker 50, which is a latching means provided on the body of the automobile, enters and exits. In the base plate 43, a groove 43a into which the striker 50 enters and exits is formed in the same manner as the groove 41b. A recess (not shown) is formed on the outer wall of the rear side wall 41a of the sub base housing 41 over the upper and lower portions of the groove 41b. A latch 44 is accommodated in the upper recess, and a pole 45 is provided in the lower recess. Contained. That is, the latch 44 and the pole 45 are disposed between the sub base housing 41 (rear side wall 41a) and the sub base plate 42.

  The latch 44 is formed in a U-shape, and has a pair of protrusions 44a and 44b, and an opening 44c formed between the protrusions 44a and 44b through which the striker 50 enters and exits. The latch 44 passes through the sub base housing 41 and is rotatably supported by a support pin 44 d mounted on the sub base plate 42 and the base plate 43. The latch 44 is urged clockwise in FIG. 5 by a torsion spring (not shown). When the door is open, the latch 44 is positioned and fixed at the position indicated by the two-dot chain line in FIG. 5 by the urging force of the torsion spring. At this time, the opening 44 c of the latch 44 matches the groove 41 b of the sub base housing 41.

  The pole 45 includes a block-shaped locking portion 45a and a shaft portion 45b extending substantially orthogonal to the locking portion 45a. The shaft portion 45 b passes through the sub base housing 41 and is rotatably supported on the sub base plate 42 and the base plate 43. A torsion spring 47 is fitted to the outer periphery of the shaft portion 45 b of the pole 45 at an intermediate portion between the sub base plate 42 and the sub base housing 41. One end of the torsion spring 47 is locked to the locking portion 45 a of the pole 45, and the other end is locked to the sub-base plate 42. The pole 45 is biased counterclockwise in FIG. 5 (clockwise in FIG. 6) by the biasing force of the torsion spring 47. Further, the pole 45 biased in this way is restricted in rotation counterclockwise by a regulating member (not shown), and is positioned and fixed at the normal position shown in FIG.

  Further, a lift lever 46 is fitted to the shaft 45b of the pole 45 at the opposite end of the locking portion 45a so as to be integrally rotatable. A contact portion 46 a is formed at the tip of the lift lever 46. The abutting portion 46a is a portion in which the abutting portion 26c of the open link 26 is detachably abutted. Since the lift lever 46 rotates integrally with the pole 45, it is urged counterclockwise in FIG. 5 (clockwise in FIG. 6) by the urging force of the torsion spring 47. Further, the lift lever 46 is positioned and fixed at a normal position indicated by a solid line in FIG. 6 by restricting the counterclockwise rotation of the pole 45 in FIG. 5 by a restriction member (not shown).

  When the door is open, the latch 44 is positioned and fixed at the position indicated by the two-dot chain line in FIG. 5 by the urging force of the torsion spring. When closing the open door, the striker 50 that has entered relatively along the groove 41b of the sub-base housing 41 comes into contact with the inner wall surface of the protrusion 44b of the latch 44, and the latch 44 is subjected to the urging force of the torsion spring. It is counterclockwise rotated. During this time, the locking portion 45a of the pole 45 is pushed down by the projecting portions 44b and 44a that are in contact with each other, and the pole 45 is rotated clockwise against the urging force. Finally, the latch 44 is rotated to the position indicated by the solid line in FIG. 5, and the locking portion 45 a of the pole 45 is locked to the protrusion 44 a of the latch 44, so that the rotation is stopped and the positioning is fixed. As a result, the hooked state where the striker 50 and the latch 44 are hooked is maintained. In this way, the latch 44 and the pawl 45 constitute the hooking means.

  When the door is opened in this latched state, the lift lever 46 is rotated clockwise in FIG. 5, and the pawl 45 is rotated in the same direction (in the direction of arrow C shown in FIG. 5). The locking portion 45a of the pole 45 is disengaged from the projection 44a of the latch 44. At this time, the latch 44 is rotated back to the position indicated by the two-dot chain line in FIG. 5 by the urging force of the torsion spring, and the opening 44 c of the latch 44 coincides with the groove 41 b of the sub base housing 41. In this state, the striker 50 can be retracted from the opening 44 c of the latch 44 and the groove 41 b of the sub base housing 41. As a result, the latching state in which the striker 50 and the latch 44 are latched is released.

  Next, the operation of the door lock device configured as described above will be described with reference to FIGS. First, a case where the door opening operation is performed when the door lock device is in the unlocked state shown in FIG. 8 and the door is not opened will be described with reference to FIG. . In the unlocked state and the door non-operating state shown in FIG. 8, the open lever 22 is positioned and fixed at the normal position, and the active lever 24 is positioned at the unlocked position, as in the state shown in FIG. The open link 26 that is fixed and supported by the two levers 22 and 24 is in an upright state. The cancel lever 32 is positioned and fixed in a state in which the cancel lever 32 is pressed by the urging force of the torsion spring 33 and is in contact with one side surface 26d of the open link 26. The lift lever 46 is positioned and fixed at the normal position.

  When the opening operation of the outside handle is performed in this state, as shown in FIG. 9, the open lever 22 located at the normal position is rotated against the urging force of the torsion spring 23, and the distal end of the second arm 22c. The part moves upward. Along with this, the open link 26 is pushed upward while standing. Then, the contact portion 26 c of the open link 26 pushes the contact portion 46 a of the lift lever 46 located at the normal position, and the lift lever 46 is rotated against the urging force of the torsion spring 47. Along with this, the locking portion 45a of the pole 45 located at the normal position also rotates. At this time, if the latching portion 45a is engaged with the latch 44, it is disengaged, and the latching state in which the striker 50 and the latch 44 are latched can be released.

  In this case, in the relationship between the open link 26 and the cancel lever 32, the open link 26 is pressed by the cancel lever 32 to the side opposite to the one side surface 26d (rightward in FIG. 9). 26a engages with the engagement protrusion 22c1 of the open lever 22 without backlash, and the engagement pin 26b of the open link 26 slides into the long hole 24d2 of the active lever 24 without backlash. When the open link 26 is pushed up and the concave portion 26e of the one side surface 26d reaches the contact portion 32b1, the cancel lever 32 rotates counterclockwise and the contact portion 32c1 of the cancel lever 32 is separated from the lift lever 46. To do. Therefore, even if the open link 26 is pushed up, the contact portion 46a of the lift lever 46 pushed up by the open link 26 can be prevented from interfering with the contact portion 32c1 of the cancel lever 32.

  Further, when the opening operation of the inside handle is performed, the inside lever 34 located at the normal position is rotated clockwise in FIG. 9 so that the contact portion 34 b 2 contacts the contact portion 22 c 2 of the open lever 22. And the front-end | tip part of the 2nd arm 22c of the open lever 22 is pushed up. Thereafter, the operation is the same as the operation by the opening operation of the outside handle.

  Next, a case where the locking operation is performed in the unlocking state and the door non-operating state shown in FIG. 8 will be described with reference to FIG. When the lock knob and key cylinder are locked or when the lock is operated by the electric motor 27, the active lever 24 positioned and fixed at the unlock position shown in FIG. 8 is rotated counterclockwise as described above. The Then, the second locking protrusion 24d4 abuts against the stop member 21g and the counterclockwise rotation is restricted, and the positioning is fixed at the lock position shown in FIG. As a result, the open link 26 that has been in a standing state is in a tilted state. Further, the cancel lever 32 in contact with the open link 26 is rotated clockwise against the urging force of the torsion spring 33, so that the contact portion 32 c 1 of the cancel lever 32 becomes the contact portion 46 a of the lift lever 46. Moved to a close position. The position is a position where the contact portion 46a of the lift lever 46 pushed up can contact the contact portion 32c1 of the cancel lever 32.

  Furthermore, a case where the door opening operation is performed in the door lock device in the locked state and the door non-operating state shown in FIG. 10 will be described with reference to FIG. When the opening operation of the inside handle is performed in the state shown in FIG. 10, as shown in FIG. 11, the inside lever 34 positioned at the normal position is rotated clockwise and the opening lever 22 is biased by the torsion spring 23. And the tip of the second arm 22c moves upward. Along with this, the open link 26 is pushed upward while being tilted. However, since the contact portion 26c of the open link 26 does not contact the contact portion 46a of the lift lever 46 located at the normal position, the lift lever 46 is not rotated. Accordingly, the locking portion 45a of the pole 45 does not rotate. At this time, if the latching portion 45a is engaged with the latch 44, the latching state where the striker 50 and the latch 44 are latched cannot be released.

  Further, when the opening operation of the outside handle is performed, the open lever 22 positioned at the normal position is rotated against the urging force of the torsion spring 23, and the tip end portion of the second arm 22c moves upward. Thereafter, the operation is the same as the operation by the opening operation of the inside handle.

  Next, assembly of the automobile door lock device described above will be described.
