Then stop.

  The worm wheel 11 is pivotally supported in the housing 8 by a shaft 813 facing inward and outward of the vehicle, and meshes with the worm 101 fixed to the rotation shaft of the motor 10 and is rotated forward and backward by the power of the motor 10.

  When the operation switch provided in the vehicle or the portable operation switch is locked in the unlocked state (the state where the lock lever 12 is in the unlocked position) shown in FIG. 8, the motor 10 rotates in the lock direction. Thus, the worm wheel 11 rotates clockwise from the position shown in FIG. 8, and the rotation is transmitted to the lock lever 12 via the protrusion 111 provided on the rotation surface of the worm wheel 11. Thereby, the lock lever 12 rotates from the unlock position to the lock position shown in FIG.

  In addition, when the operation switch provided in the vehicle or the portable operation switch is unlocked in the locked state shown in FIG. 9 (the lock lever 12 is in the locked position), the motor 10 rotates in the unlocking direction. As a result, the worm wheel 11 rotates counterclockwise from the position shown in FIG. 9, and the rotation is transmitted to the lock lever 12 via the protrusion 111 of the worm wheel 11. Thereby, the lock lever 12 rotates from the lock position to the unlock position shown in FIG.

  The outside lever 18 is pivotally supported by a lower portion of the case 81 by a shaft 812 in the front-rear direction, and the lower ends of the first and second lift levers 13 and 14 are arranged around a predetermined angle at the operating end portion 181 of the vehicle inner end portion. The vehicle is connected to the outside handle via an operating force transmission member (not shown) that faces in the vertical direction. Thus, when the outside handle is operated to open the door, the outside lever 18 moves from the standby position (for example, see FIG. 1) to the opening direction (FIG. 1) against the urging force of the spring provided around the shaft 812. In the clockwise direction).

  The upper portion of the first lift lever 13 can swing a predetermined angle in the front-rear direction around the operating end 181 of the outside lever 18, and the protrusion 122 of the lock lever 12 slides in the elongated hole 131 in the vertical direction. Engageable.

  When the lock lever 12 rotates from the lock position to the unlock position or vice versa, the first lift lever 13 swings together with the lock lever 12 from the unlock position shown in FIG. 8 to the lock position shown in FIG. Move. When the outside lever 18 pivots from the standby position in the opening direction, the first lift lever 13 moves from the locking position to the opening direction (upwardly obliquely upward) when the lock lever 12 is in the locking position. When the lever 12 is in the unlock position, the lever 12 moves from the unlock position in the opening direction (upward).

  The upper portion of the second lift lever 14 can swing a predetermined angle in the front-rear direction around the operating end portion 181 of the outside lever 18, and the urging force of the spring 23 acting between the first lift lever 13 and the second lift lever 14. Within the range, the first lift lever 13 is moved integrally to the unlock position shown in FIG. 8 and the lock position shown in FIG.

  The second lift lever 14 is provided with a release portion 141 that can contact the open lever 71 in the rotational direction. When the opening end of the outside lever 18 rotates, the operating end 181 moves upward, and when the second lift lever 14 moves together with the first lift lever 13 from the unlock position to the opening direction, the release portion 141 rotates the open lever 71. The open lever 71 can be rotated in the open direction by contacting the moving end portion from below, and the ratchet 7 can be detached from the latch 6 to open the door. However, when the second lift lever 14 moves together with the first lift lever 13 from the locked position in the open direction, the release portion 141 simply moves so as to cross the front of the open lever 71, and the opening lever 71 rotates. The door cannot be opened by swinging against the moving end.

  The child proof lever 17 is pivotally supported in the housing 8 by a shaft 814 facing inward and outward of the vehicle, and a manual operation portion 172 provided at the rear end and protruding inward of the vehicle is operated, thereby opening the door of the inside handle. 8 and 9 are turned to the lock position shown in FIGS. 8 and 9 and turned to the lock position shown in FIG. Only when the door is opened, the manual operation unit 172 is exposed from a long hole 827 provided in the lower portion of the cover 82 and a long hole (not shown) provided in the inner panel of the door so that manual operation is possible.

  A hooked floating pin 24 is slidably engaged in the front-rear direction in a longitudinal hole 171 provided in the front part of the child proof lever 17.

  The inside lever 15 is pivotally supported in the housing 8 by a shaft 811 and is bent in a crank shape toward the inside of the vehicle so as to be exposed to the outside of the cover 82 through an arc-shaped opening 821 provided on the upper side of the cover 82. The formed connecting portion 151 and a substantially T-shaped control hole 152 into which the floating pin 24 is slidably engaged are provided. By connecting the terminal of the operating force transmission member 20 composed of a Bowden cable or the like capable of transmitting the operating force of the inside handle to the connecting portion 151, the inside lever 15 is operated based on the door opening operation of the inside handle, for example, FIG. Is rotated by a predetermined angle in the open direction (counterclockwise) from the standby position shown in FIG.

  The linkage lever 16 is pivotally supported in the housing 8 by a shaft 811 and has an elongated hole 161 in which the floating pin 24 is slidably engaged in the vertical direction, and an open operation (clockwise from the position shown in FIGS. 8 to 10). And a pushing portion 162 that can come into contact with the turning end 183 of the outside lever 18 from below.

  As shown in FIGS. 8 and 9, when the child proof lever 17 is in the unlocked position, the floating pin 24 is positioned below the control hole 152 of the inside lever 15 so that the opening operation of the inside lever 15 is performed. In addition, as shown in FIG. 10, when the child proof lever 17 is in the locked position, it is positioned above the control hole 152 so that the opening operation of the inside lever 15 cannot be transmitted to the linkage lever 16. To do.

  As shown in FIG. 8, when both the lock lever 12 and the child proof lever 17 are in the unlocked position, when the inside lever 15 is opened based on the door opening operation of the inside handle, the opening operation is floating. It is transmitted to the linkage lever 16 via the pin 24. As a result, the linkage lever 16 is opened together with the inside lever 15, and the pushing portion 162 abuts against the turning end 183 of the outside lever 18 in the turning direction from below, so that the outside lever 18 is moved. Turn in the open direction. When the outside lever 18 rotates in the open direction, the second lift lever 14 moves upward, and the release portion 141 contacts the rotation end of the open lever 71, thereby rotating the open lever 71 in the open direction. Thus, the ratchet 7 can be detached from the latch 6 to open the door.

  As shown in FIG. 10, when the lock lever 12 is in the unlocked position and the child proof lever 17 is in the locked position, the floating pin 24 is positioned above the control hole 152 and the inside lever 15 and the linkage lever 16. The connection relationship with is disconnected. Accordingly, even if the inside lever 15 is opened based on the door opening operation of the inside handle, the opening operation is not transmitted to the linkage lever 16, so that the door of the inside handle is not affected even when the lock lever 12 is in the unlocked position. The door cannot be opened by opening operation.

  Next, the housing 8 and the water proof cover 9 will be described. An arc-shaped opening 821 centering on the rotation center of the inside lever 15 is formed in the upper side surface of the cover 82, and an opening 826 in the front-rear direction is formed in the lower part of the side surface of the cover 82.

  The opening 821 exposes the connecting portion 151 of the inside lever 15 pivotally supported in the housing 8, so that the terminal of the operating force transmission member 20 is connected to the connecting portion 151 in a state where the inside lever 15 is pivotally supported in the housing 8. It is for making it connectable to. Further, the opening 826 exposes the connecting portion 121 of the lock lever 12 pivotally supported in the housing 8, thereby connecting the terminal of the operating force transmission member 21 in a state where the lock lever 12 is pivotally supported in the housing 8. This is to allow connection to the part 121.

  A synthetic resin lid member 19 capable of opening and closing the opening 826 is connected to the front and rear connecting portions 828 and 828 provided in the lower portion of the cover 82 so as to be rotatable about an axis in the front-rear direction. The cover member 19 covers the connecting portion 121 of the lock lever 12 exposed from the opening 826, thereby preventing the connecting portion 121 of the lock lever 12 from attacking illegally and improving the anti-theft property. It prevents rainwater from entering and improves water resistance. The lid member 19 is closed after the end of the operating force transmission member 21 is connected to the connecting portion 121 of the lock lever 12.

  Most of the rain water dripping on the upper portion of the housing 8 is received by the water proof cover 9 attached to the upper portion of the housing 8, but when the amount of rain water is large, a gap between the housing 8 and the water proof cover 9 is used. In some cases, it may penetrate. Therefore, in order to prevent rainwater that has entered the gap between the housing 8 and the water proof cover 9 from entering the housing 8 from the opening 821, the rainwater that has entered the side of the cover 82 is received near the opening 821. First, second, and third horizontal flange portions 822, 823, and 824 and a flange portion 825 that can be guided in a predetermined direction are formed.

  The first recumbent portion 822 is located above the opening 821 and extends obliquely forward and downward in a form protruding by a predetermined amount toward the inside of the vehicle. The first recumbent portion 822 enters the gap between the water proof cover 9 and the upper surface of the housing 8 and hangs down. The rainwater is received and guided forward and obliquely downward to flow forward from the opening 821.

  The second recumbent part 823 is below the first recumbent part 822 and above the opening 821, and extends obliquely forward and downward with a predetermined amount protruding toward the vehicle interior, and hangs down in the middle of the first recumbent part 822. The rainwater is received and guided obliquely forward and downward to flow forward from the opening 821.

  The third recumbent part 824 is provided below the second recumbent part 823 and along the upper edge of the opening 821, receives rainwater dripping in the middle of the second recumbent part 823, and guides it forward and obliquely downward. Flow down to the front of 821.

  The collar portion 825 is formed from the rear end (top portion) of the first lateral collar portion 822 so as to shield the rear of the opening 821 so that rainwater dripping from the upper surface of the rear portion of the housing 8 does not flow into the opening 821 in particular. Extend downward.

  The rainwater received by the first recumbent portion 822 and guided obliquely downward to the front follows the flow path A indicated by the arrow in FIG. 3 and falls from the lower end of the housing 8. Rainwater received by the second and third recumbent portions 823 and 824 and guided obliquely forward and downward follows the flow path B indicated by an arrow in FIG. 3 and falls from the lower end of the housing 8. Further, the rainwater guided to the collar portion 825 falls from the lower end of the housing 8 along the flow path C indicated by the arrow in FIG. Note that walls a to e (see FIG. 3) are formed on the side surface of the cover 82 so as to flow rainwater along the flow paths A, B, and C.

  The water proof cover 9 is made of synthetic resin, is fixed to the upper portion of the housing 8, and covers an upper surface cover portion 91 that obliquely tilts forward and covers the upper surface of the housing 8, and an upper side surface of the case 81 outside the vehicle. A lid portion 93 that can be bent with respect to the vehicle outer side covering portion 92 and the upper surface covering portion 91 and that can open and close the upper side surface including the opening 821 of the cover 82, and the lid portion 93 with respect to the upper surface covering portion 91. A downward reinforcing wall portion 95 that is provided along a fold line 941 (see FIG. 13) of the fold portion 94 that is foldably connected and abuts on the upper side surface of the cover 82 is integrally formed. The bent portion 94 is continuously formed in a thin shape along the boundary portion of the corner portion connecting the lid portion 93 and the reinforcing wall portion 95.

  The lid portion 93 can be bent from the bending portion 94 so that the opening 821 can be opened and closed. For example, as shown in FIG. 3, the lid portion 93 is opened to expose the terminal of the operating force transmission member 20 from the opening 821. The connecting portion 151 of the lever 15 can be connected, and for example, as shown in FIG. 2, the opening 821 and the connecting portion 151 of the inside lever 15 are covered so as not to be illegally attacked. It is intended to improve the water resistance by improving the anti-theft property and preventing rainwater from entering the opening 821. Moreover, in order to be able to bend the cover part 93 with respect to the upper surface cover part 91, the notch and the joint are not formed in the boundary part of the cover part 93 and the upper surface cover part 91, ie, the bending part 94, at all. Therefore, a reliable waterproof effect can be obtained.

  In addition, since the reinforcing wall portion 95 that contacts the side surface of the housing 8 is formed along the fold line 941 of the fold portion 94, the rigidity in the vicinity of the fold portion 94 can be improved. Thereby, when performing the operation | work which connects the terminal of the operating force transmission member 20 to the connection part 151 of the inside lever 15, the lid | cover part 93 is held in the open state in a stable state without shaking, and the operation force transmission member 20 can be easily connected to the connecting portion 151 of the inside lever 15. Furthermore, when the lid portion 93 is closed, deformation due to secular change in the vicinity of the bent portion 94 is suppressed by the reinforcing wall portion 95, so that the gap between the back surface of the water proof cover 9 and the front surface of the housing 8 is suppressed. As a result, the intrusion of rainwater can be more reliably prevented.

  On the surface of the lid portion 93, an identification mark 932 representing the type of the door latch device 1, and a mesh-like ridge portion that exhibits an anti-slip effect for assembly work on the operator, as shown in particular in FIGS. 934 is formed. The identification mark 932 is provided at a position where it can be surely seen from the closing direction of the lid portion 93 (the arrow direction shown in FIG. 12) when the operator closes the lid portion 93. Thereby, when the operator closes the lid portion 93, the identification mark 932 is confirmed, so that erroneous assembly of the door latch device 1 to the vehicle can be surely prevented. Note that the side surface of the case 81 is also provided with a mesh-like ridge 815 having the same shape as the ridge 934 formed on the surface of the lid portion 93 in order to ensure a non-slip effect.

  That is, the door latch device 1 includes an internal structure having a function corresponding to each vehicle type. However, in order to promote the common use of automobile parts, the appearance shape is very similar even if the functions of the internal structure are different from each other. In general, the door latch device 1 is manufactured by a parts manufacturer and delivered to a car manufacturer. The worker of the car manufacturer then attaches the terminals of the operation force transmitting members 20 and 21 to the inside lever immediately before assembling the door latch device 1 to the door in the vehicle assembly process in order to assemble the delivered door latch device 1 to the vehicle door. 15 and the connecting portions 151 and 121 of the lock lever 12 are connected to each other to attach the door latch device 1 to the door. Conventionally, the correct door latch device 1 to be attached is properly attached before the assembly operation is completed. It was difficult to confirm.

  On the other hand, in the present invention, the end portions of the operating force transmission members 20 and 21 are connected to the connecting portions 151 and 121 of the inside lever 15 and the lock lever 12, respectively, and the lid portion 93 and the lid member 19 are closed. The operator confirms the identification mark 932, and accordingly, if it is different from the door latch device 1 to be assembled due to erroneous conveyance or the like, the operator attaches the terminal of the operating force transmission member 20 to the connecting portion 151 of the inside lever 15. It is possible to confirm the correctness of the door latch device 1 by confirming the identification mark 932 at the stage of a series of assembly operations for connecting and closing the lid portion 93. As a result, erroneous assembly of the door latch device 1 to the vehicle can be reliably prevented. Further, since the surface of the lid portion 93 is provided with a mesh-like ridge portion 934 that has an anti-slip effect, the lid portion 93 is attached after the operating force transmission member 20 is coupled to the coupling portion 151 of the inside lever 15. It can be easily closed. Furthermore, since the protrusions 815 that provide the anti-slip effect are also provided on the side surface of the case 81, the operator can reliably grasp the operation unit 3 and can improve the work efficiency.

  On the back surface of the lid portion 93 that faces the side surface of the cover 82, the lateral side surface that protrudes toward the side surface of the cover 82 and that slopes down forward and contacts the side surface of the cover 82 along the upper side of the first lateral surface portion 822. The part 931 is integrally formed. As a result, even if rainwater enters the gap between the upper surface cover portion 91 of the water proof cover 9 and the upper surface of the housing 8, the rainwater that has entered is received by the recumbent portion 931 and guided diagonally forward and downward. , It can be made to flow forward from the opening 821. Further, the rain water flowing from the middle of the recumbent portion 931 is received by the first, second and third recumbent portions 822, 823, and 824 provided on the cover 82 and follows the flow paths A and B from the lower end of the housing 8. Drop it. Further, the back surface of the lid portion 93 that faces the side surface of the cover 82 is engaged with an engagement hole 829 provided in the cover 82 when the lid portion 93 is closed, so that the lid portion 93 is held in a closed state. The elastic claw portion 933 is integrally formed.

16 and 17 show another embodiment of the water-proof cover 9 according to the present invention.
The water proof cover 90 according to another embodiment is suspended from an upper surface cover portion 901 that covers the upper surface of the housing 8 and an end of the upper surface cover portion 901 on the vehicle outer side (left side in FIGS. 16 and 17). A side cover (not shown) that covers the upper side of the housing 8 and a side cover 906 that hangs down from the end of the top cover 901 on the vehicle inner side (right side in FIGS. 16 and 17) and covers the upper side of the housing 8 inside the vehicle. And a lid portion 903 that can be bent with respect to the side surface covering portion 906 and can open and close the opening 821 of the housing 8, and the lid portion 903 that can be bent with respect to the side surface covering portion 906 in the same manner as in the above-described embodiment. A downward reinforcing wall portion 905 that is provided along the bent portion 904 formed on the inner side of the housing 8 and abuts against a side surface of the housing 8 on the vehicle inner side is integrally formed.
