PROBLEM TO BE SOLVED: To provide a vehicular door latch device which alleviates contact point failure due to silicone pollution.SOLUTION: A vehicular door latch device includes: a door opening mechanism 31 for opening a latch unit; a main lock mechanism 32 for switching the door opening mechanism 31 between a lock position and an unlock position by the power of a motor 45; a switch base 35 including a conducting circuit with respect to the motor 45 and a state detection switch 53 of the main lock mechanism 32; and a housing 24 having a mechanism storage part 30 for storing the door opening mechanism 31, the main lock mechanism 32, an actuator mechanism 34 and the switch base 35. Grease to be coated in the mechanism storage part 30 is equal to or less than silicon 100 ppm, and the grease is not coated in the neighborhood of the switch base 35 and the motor 45.SELECTED DRAWING: Figure 2
【課題】シリコーン汚染による接点不良を軽減させる車両ドアラッチ装置を提供する。【解決手段】ラッチユニットを解放する開扉機構３１と、モータ４５の動力で開扉機構３１をロック位置とアンロック位置に切り替えるメインロック機構３２と、モータ４５に対する通電回路やメインロック機構３２の状態検知スイッチ５３を備えたスイッチ基盤３５と、開扉機構３１とメインロック機構３２とアクチュエータ機構３４とスイッチ基盤３５とを収納する機構収納部３０を有するハウジング２４とを備え、機構収納部３０内に塗布するグリスはシリコン１００ｐｐｍ以下とすると共に、スイッチ基盤３５およびモータ４５の近傍にはグリスを塗布しない構成とした。【選択図】図２
