  As shown in FIGS. 1 to 6, the door lock device 1 includes a lock portion 2 and a key rotor portion 3.

<Structure of Locking Part>
The lock portion 2 has the main housing 7 shown in FIGS. 1, 2 and 4, the lock lever 20 shown in FIGS. 2 and 4, and the lock portion body 10 shown in FIGS. 1, 5 and 6. ing.

  The main housing 7 is an injection-molded article of a thermoplastic resin in this embodiment. The main housing 7 is fixed inside the rear end side of a vehicle door (not shown). The main housing 7 is configured to include a first housing 7A and a second housing 7B. A storage chamber (not shown) is formed in the main housing 7 by assembling the lid-shaped second housing 7B to the box-shaped first housing 7A.

  In the storage chamber of the main housing 7, a transmission mechanism (not shown) for transmitting the operation of the transmission rod C1 and the transmission cable C2 shown in FIG. 1 as the displacement of the transmission part 15 shown in FIGS. 5 and 6 is disposed.

  As shown in FIG. 1, the transmission rod C1 transmits the operation of an outer door handle (not shown) provided on the outside of the vehicle door to the transmission mechanism in the main housing 7. The transmission cable C2 transmits the operation of an inner door handle (not shown) provided inside the vehicle door to the transmission mechanism in the main housing 7.

  For example, when the rider operates the outer door handle or the inner door handle, the operation is transmitted to the transmission mechanism via the transmission rod C1 or the transmission cable C2. Then, the transmission mechanism operates to displace the transmission unit 15 from the state shown in FIG. 5 to the state shown in FIG. In addition, since a transmission mechanism is a known link mechanism which consists of a gear, a lever, etc., detailed description is abbreviate | omitted.

  As shown in FIG. 2, the lock lever 20 is swingably supported on a wall surface of the second housing 7 </ b> B facing the vehicle interior. A shaft 23 is formed at the tip of the lock lever 20 so as to protrude inward of the vehicle. On the tip side outer periphery of the shaft portion 23, a claw portion 23A which can be elastically deformed in a radially inward direction is formed.

  The lock lever 20 acts on the transmission mechanism to prohibit or allow the transmission unit 15 to be displaced from the state shown in FIG. 5 to the state shown in FIG. The position of the lock lever 20 shown by a solid line in FIG. 2 is a neutral position. When the lock lever 20 pivots from the neutral position in the counterclockwise direction in FIG. 2 to a position 20U indicated by a two-dot chain line in FIG. 2, the displacement of the transmission portion 15 is allowed to unlock the vehicle door. It will be in the state. On the other hand, when the lock lever 20 pivots from the neutral position shown by the solid line in FIG. 2 in the clockwise direction of FIG. 2 to the position 20L shown by the alternate long and two short dashes line in FIG. Lock the vehicle door. The lock lever 20 is biased by a return spring (not shown) incorporated in a key cylinder 9 described later so as to return to the neutral position shown by a solid line in FIG.

  The lock portion main body 10 includes the mounting member 19 shown in FIGS. 1, 2 and 4 to 6, the fork 11 shown in FIGS. 1, 2, 5 and 6, and the pole 12 shown in FIGS. And is included. The mounting member 19 is assembled to the rear end portions of the first housing 7A and the second housing 7B. The mounting member 19 is a plate-like member made of steel which is press-processed or the like in the present embodiment. The door lock device 1 is fixed to the vehicle door by fastening the mounting member 19 to the rear end side of the vehicle door.

  The mounting member 19 is formed with an entrance 19C which is notched in a groove shape deeply from the inside to the outside of the vehicle. As shown in FIG. 5, when the door lock device 1 is moved with the opening and closing of the vehicle door, the striker S1 fixed to the vehicle body relatively enters the entrance 19C.

  The fork 11 is swingably supported by a fork swing shaft 11S positioned above the entrance 19C. The fork 11 is biased by a coil spring (not shown) so as to rock in the counterclockwise direction of FIGS. 5 and 6 around the fork rocking shaft 11S.

  The pole 12 is swingably supported by a pole swinging shaft 12S located below the entrance 19C. The pole 12 is biased by a coil spring (not shown) so as to swing clockwise in FIGS. 5 and 6 around the pole swinging shaft 12S, and maintains the posture shown in FIG.

  The portion of the fork 11 located on the entrance 19C side is branched into the inner convex portion 11A and the outer convex portion 11B. And striker S1 which entered into entrance 19C is settled in notch 11C formed between inner side convex part 11A and outer side convex part 11B. In the state shown in FIG. 5, the fork 11 holds the striker S1 at the bottom of the entrance 19C. A latch surface 11D that can abut against a stopper portion 12A described later is formed on the tip side of the inner convex portion 11A facing the pole 12.

  A stopper surface 12A is formed at a portion of the pole 12 located on the bottom side of the entrance 19C. The stopper surface 12A is formed to face the latch surface 11D. The arc forming the stopper surface 12A is interrupted on the fork 11 side, and a sliding surface 12C extending therefrom toward the pole rocking shaft 12S is formed. A receiving portion 12B is formed on the pole 12 on the opposite side of the pole swinging shaft 12S to the stopper surface 12A.

  As shown in FIG. 5, in the state where the fork 11 holds the striker S1 at the bottom of the entrance 19C, as shown in FIG. 5, the stopper surface 12A abuts on the latch surface 11D of the inner convex portion 11A. 5 and fixed so as not to swing counterclockwise in FIG. The position of the fork 11 shown in FIG. 5 is a latch position for holding the striker S1 in the entrance 19C. When the fork 11 is in the latch position, the lock portion 2 holds the vehicle door closed with respect to the vehicle body.

  When the vehicle door is in the unlocked state, when the rider operates the outer door handle or the inner door handle, the operation is transmitted to the transmission mechanism via the transmission rod C1 or the transmission cable C2, and the transmission portion 15 Is displaced from the state shown in FIG. 5 to the state shown in FIG. 6 to push up the receiver 12B. Thereby, as shown in FIG. 6, the pole 12 swings in the counterclockwise direction of FIGS. 5 and 6 around the pole swinging axis 12S while resisting the biasing force of a coil spring (not shown). At this time, since the stopper surface 12A is separated from the latch surface 11D, the pole 12 releases the swing of the fork 11. Then, the unlatch position where the fork 11 swings counterclockwise in FIGS. 5 and 6 around the fork swinging shaft 11S by the biasing force of a coil spring (not shown) and allows the striker S1 to separate from the inside of the entrance 19C. Displace. When the fork 11 is in the unlatched position, the lock unit 2 allows the vehicle door to be opened.

  Conversely, when the striker S1 enters the entrance 19C by the rider trying to close the vehicle door, the striker S1 pushes the outer convex portion 11B, so the fork 11 rotates clockwise in FIGS. 5 and 6. And returns from the unlatched position shown in FIG. 6 to the latched position shown in FIG. At this time, the tips of the outer convex portion 11B and the inner convex portion 11A sequentially slide on the sliding surface 12C. Then, when the inner convex portion 11A separates from the sliding surface 12C, the pole 12 swings clockwise in FIGS. 5 and 6 and returns to the original posture shown in FIG. Therefore, the stopper surface 12A abuts on the latch surface 11D to fix the swing of the fork 11 in the latch position. As a result, the lock unit 2 holds the vehicle door closed with respect to the vehicle body.

  On the other hand, when the vehicle door is in the locked state, the transmission portion 15 of the transmission mechanism can not be displaced from the state shown in FIG. 5 even if the rider operates the outer door handle or the inner door handle. For this reason, the lock portion 2 holds the vehicle door closed with respect to the vehicle body regardless of the rider's steering wheel operation.
