In left rotation (forward rotation), as shown in FIG. 3, the ratchet for full
The metal pawl 19 of the slot 12 and the full latch engagement step 15 open.
The metal claws 19
Although but are full latch engages fully latched engagement step 15, the conventionally known ones, when vigorously door closing as the full-latch, the latch 8 is forward rotated at a considerable speed by the engagement of the striker 2 And therefore, necessarily,
The excess rotation amount also increases. Therefore, the rotation speed at the time of reverse rotation of the latch 8 (backward rotation) is also faster in proportion, when a full latch engagement step 15 of the engagement of the metal claw 19, thereby considerably generate large metallic sound.

Is, for example, full so that the above relationship is satisfied
When the latch engagement step 15 is at the lower position, the half latch engagement step
The part 14 is on the upper side, and the half ratchet 10 is on the side therebetween.
Is provided on the side.

When the door is vigorously closed, the striker 2 on the vehicle body engages with the engagement groove 13 of the latch 8 of the lock body 1 on the door side, and vigorously rotates the latch 8 counterclockwise in FIG . However, the present invention
Also , when the door is being rotated as shown in FIGS. 1 and 2 , as shown in FIG. 2, the projecting member 17 formed on the latch 8 and the projecting member 18 formed on the half ratchet 10 are mutually opposed. And the rotation of the latch 8 is decelerated. For this reason,
Excess amount of rotation beyond the full latch position of the latch 8 as shown in FIG. 3 will be reduced.

The full metal claw 19 of the full-latch engagement step 15 and the full ratchet 12 of metal to collide with each other
But of being Ruratchi, just before the full-latch, again,
The protruding member 17 and the protruding member 18 come into contact with each other to reduce the rotation speed of the latch 8. Therefore, mutual collision noise with the metal of full <br/> Le latch engaging step portion 15 and the metal claw 19 is significantly mitigated.

The claws are provided with a synthetic resin coating layer to ensure that the latch
A synthetic resin coating layer is provided on the back of the latch engagement step.
Therefore, when the synthetic resin coating layers collide with each other,
Effect of reducing the rotational speed can be expected. However, the ratchet
Is one, the over-rotated latch returns and full latch
Reduces abnormal noise when contacting the metal part of the engaging step
I can't do that . However, the present invention is, half the vehicle door
Forming latch engaging step 14 and full latch engaging step 15
Latch 8 and the half latch engagement step 14
Half ratchet 10 and full latch engagement step 15
And a full ratchet 12 for engaging the
The half ratchet 10 projects in the direction of the latch 8
A projection 18 made of synthetic resin is provided.
Projecting in the radial direction, and when the door is closed, the synthetic resin projection
Abuts against the material 18 to reduce the rotational speed of the latch 8;
Further, the latch 8 that has excessively rotated returns to the full latch position.
When the full ratchet 12 is engaged with the engagement step portion 15,
At the time of road rotation, it comes into contact with the synthetic resin
Synthetic resin projecting member 17 for reducing the rotation speed of the switch 8
Since it is obtained by a locking sound reduction device for a vehicle locking device provided with, when closing, protruding formed in the latch 8
Projection member formed on member 17 and half ratchet 10
18 to contact each other to reduce the rotation of the latch 8
Therefore, the excessive rotation amount of the latch 8 beyond the full latch position is reduced.
Latch 8 can be reduced even if it rotates excessively.
The repulsive force of the rubber seal provided between the door and the vehicle body, and
Reversing by the elasticity of the latch reverse rotation spring and returning rotation,
Full-latch engagement step 15 of metal and ratchet 12 for full
Metal claws 19 collide with each other and are fully latched ,
Immediately before the full latch, the projecting member 17 and the projection
The rotation speed of the latch 8 is reduced by contact with the member 18.
You. Therefore, the metal full latch engagement step 15 and the metal
Of each other with the claws 19 is considerably reduced .
