摘要： A vehicle door latch apparatus is provided that shortens the time to switch the locking lever between the locked position and the unlocked position. A vehicle door latch apparatus according to the present invention comprises a latch that is engaged with a striker in order to keep a vehicle door in a half-latched state or a full-latched state; a ratchet that is engaged with the latch in order to keep the latch engaged with the striker; an opening link 27 that abuts against the ratchet in order to release the ratchet from the latch when the opening link is moved in a door opening direction in an door opening operation of an outer door opening handle; a locking lever 28 that can be switched between a locked position that prevents the ratchet from being released by the opening link and an unlocked position that allows the ratchet to be released; and a locking actuator 39 that switches the locking lever between the locked position and the unlocked position. The locking actuator includes a motor 40 and an output wheel 42 that is driven by the motor, and the output wheel has a protruding or recessed first connecting part 45 and the locking lever has a recessed or protruding second connecting part 46 that is connected to the first connecting part.

摘要： A door closing apparatus includes a latching mechanism including a latch, a closing mechanism configured to shift the latching mechanism from a half latching state to a fully latching state, and a driving source configured to operate the closing mechanism. The closing mechanism includes a closing lever that is rotated by power of the driving source, a closing arm that is translated in response to a rotation of the closing lever to be linked with the latch and a cancelling lever that rotates in response to an operation of a door opening operation source. The closing lever has a closing lever shaft that is supported by the cancelling lever, and the supporting of the closing lever shaft by the cancelling lever is cancelled by a rotation of the cancelling lever in response to an operation of the door opening operation source.

摘要： Provide a door latch apparatus with a childproof lock mechanism that is only a projecting portion of the childproof lock mechanism is movable in the release direction interlocked with an opening operation of an inside lever, so that the degree of freedom of arrangement and design of several kinds of parts assembled in a housing can be increased. A release actuating member is supported movably in an elongated guide hole of a childproof lever from a standby position to a release position. When the childproof lever is in a childproof unlocking position and when an inside lever is carried out the opening operation, a projecting portion contacts to the inside lever and moves in the opening direction, so that the release actuating member moves to the release position against a biasing unit.

摘要： A latch device for a vehicle includes: a latch configured to hold and engage with a striker; and a latchet configured to maintain an engagement condition between the striker and the latch by meshing with the latch. Between a meshing surface of the latch and a meshing surface of the latchet that mesh with each other, one meshing surface is formed narrower than the other meshing surface. A supporting member is arranged at a side of the latch or the latchet having the one meshing surface narrower than the other meshing surface with a gap provided between a side face of the latch or the latchet and the supporting member. A periphery of the supporting member including the end face is covered with a resin material and the gap is filled up with the resin material.

摘要： In a vehicle door latch apparatus, a one-motion operation can be allowed. Switching element is in a double unlocked state when it is in the connected position and is in a double locked state when it is in the disconnected position. The double unlocked state enables a one-motion operation, in which switching element is linked to the release operation of first inside lever in order to switch the locking mechanism from the locked state to the unlocked state and in which the release operation of first inside lever is transmitted to second inside lever in order to open the door, and in the double locked state, switching element is not linked to the release operation of first inside lever, prevents the release operation of first inside lever from being transmitted to second inside lever and prevents the locking mechanism from being switched from the locked state to the unlocked state.
