ント板１１に垂直な前後方向に案内されることになる。Further, since the rear end of the trigger bolt 63 slidably penetrates the guide member 64 having an L-shaped cross section, which is fixedly provided in the lock box 1, the trigger bolt 63 is eventually attached to the front plate 11. You will be guided in the vertical direction.

してラッチボルト３が前方に突出する。With the above-mentioned structure, in the silencer for the latch bolt according to the present invention as defined in claim 2, the front end of the trigger bolt 63 at the time of closing the door engages with the door frame and is pushed into the lock box by the wedge action. As the engaging protrusion 66 moves the front end of the trigger body 5 rearward, and as a result, the trigger body 5 rotates counterclockwise, the locking lever 42 is released from the trigger body 5. Then, in the same manner as described above, the latch bolt 3 projects forward.

でも無い。Also at this time, since the torque shaft 81 and the torque bearing 86 rotate relative to each other with the high-viscosity substance 9 sandwiched therebetween, the biasing force of the latch bolt is attenuated by that amount and loses momentum, and the latch bolt is lost. Needless to say, is decelerated and buffered.

音を著しく低減させるという効果を奏する。According to the silencer for the latch bolt in the lock of the present invention described above, when the door is closed and the latch bolt is automatically projected, the biasing force is transmitted to the pinion through the rack tooth row. In the path, it is damped by the high-viscosity substance applied to the fitting part of the torque shaft and torque bearing, so the collision noise when the latch bolt contacts the strike plate or when the latch bolt stopper collides is significantly reduced. There is an effect of making it.

んど垂れない状態で密封できるなどの効果を奏する。Further, when the torque shaft and the torque bearing are made of a synthetic resin material, the conduction of the sound from the pinion to the lock box can be prevented, the sound reducing effect can be further enhanced, and the fitting between the torque shaft and the torque bearing is possible. This has the effect of sealing the highly viscous substance applied to the part with almost no dripping.
