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
