When the door is open, the rod-shaped projection 29 of the ratchet 11
corresponds to the engagement piece 47 of the operating rod 8 as shown in FIG. The lock lever 9 does not rotate even if the lock lever 9 is tried to move to the counterclockwise direction (in the figure), thereby preventing the key from being left behind.

However, when the door opening handle is operated to open the door, the bar-shaped protrusion 29 and the engagement piece 47 are displaced, and the bar-shaped protrusion 29
faces the gap 48 (Fig. 24), presses the sill knob to rotate the lock lever 9, and moves the operating rod 8 so that the bar-like protrusion 29 is positioned outward through the gap 48. In this state, when the door is closed, , striker 4
and the engagement groove 33 of the latch 10 on the lock body side (FIGS. 16 to 18), and the pawl 34 of the latch 11 engages with the full engagement step 36 to lock the latch 10.
This prevents the door from reversing and allows the door to close in the locked state. At the same time, as shown in FIG.
The locked state is maintained by hitting the ball.

In this state, even if the open lever 7 is rotated clockwise and the operating rod 8 is moved, the abutment piece 22 and the rod-shaped protrusion 29 of the ratchet 11 are out of position, so the ratchet 11 cannot be rotated. figure,
It is locked due to a so-called whiff.

(Effects) In the conventionally known Japanese Patent Application Laid-open No. 50-111724, a synthetic resin body is attached inside the door, and a latch having a full engagement step on the front side of the body is engaged with the engagement step. A latch for preventing the latch from reversing is provided so that the latch is located below the latch, and the latch is attached to a shaft provided at a position farther away in the reversal direction than the engagement step when the door is closed. A bulge is formed on the back side of the body to serve as an entry path for the striker, and a shaft for locking the latch is provided in the bulge to engage with the engagement step in a compressed state. A shaft for fixing the ratchet is located below the bulge and a pawl lever is fixed to the shaft, and the open lever is always fixed to the shaft. One end side is biased by a spring so as to move upward, and the upper end of the open connect lever, which has a rod connected to the door opening handle and an engagement piece for a keyless lock, is connected, and the pole lever is pivoted to another shaft. A keyless lock device for a vehicle lock device coupled to a lock lever is described.

The ratchet of the known keyless lock device is fixed to a shaft provided at a position farther away from the engagement step in the reverse rotation direction when the door is closed, and engages with the engagement step in a compressed state. Since it is provided, it can withstand a strong latch reversal force, but as described in the above-mentioned publication, there is a problem that the structure becomes large, complicated, and heavy.
