Vehicular door lock device
A vehicular door lock device includes: a base portion rotatably supporting a latch holding a vehicle door in a closed state by engaging with a striker; a switching mechanism switching between a lock state where releasing of the engagement between the latch and the striker during a door opening operation of a door operation handle provided on the vehicle door is prohibited and an unlock state where releasing of the engagement between the latch and the striker during the door opening operation of the door operation handle is allowed; an electric mechanism capable of electrically switching the switching mechanism between the lock state and the unlock state; a housing accommodating the switching mechanism and the electric mechanism and connected to the base portion; and a blocking member disposed in the housing. An opening through which an operation tool is insertable is provided on the base portion.
1. A vehicular door lock device comprising:
a base portion rotatably supporting a latch holding a vehicle door in a closed state by engaging with a striker;
a switching mechanism switching between a lock state where releasing of the engagement between the latch and the striker during a door opening operation of a door operation handle provided on the vehicle door is prohibited and an unlock state where releasing of the engagement between the latch and the striker during the door opening operation of the door operation handle is allowed;
an electric mechanism capable of electrically switching the switching mechanism between the lock state and the unlock state;
a housing accommodating the switching mechanism and the electric mechanism and connected to the base portion; and
a blocking member disposed in the housing, wherein
an opening through which an operation tool is insertable from an outside of the base portion into the housing is provided at a part of the base portion facing the switching mechanism,
the blocking member allows an operation for inserting the operation tool from an outside of the housing into the housing through the opening and an operation for switching the switching mechanism from the unlock state to the lock state by means of the operation tool inserted in the housing as a result of the operation, and blocks the opening when the operation tool is not inserted through the opening,
the blocking member is made of rubber and has a blocking portion having a shape blocking the opening, and
a slit allowing the operation tool to be inserted therein is formed in the blocking portion.
2. The vehicular door lock device according to claim 1 , wherein
the blocking portion has a pair of guide surfaces provided at positions sandwiching the slit, and
the pair of guide surfaces are shaped so as to approach each other from the outside of the housing toward an inside of the housing.
3. The vehicular door lock device according to claim 1 , wherein
the base portion has a holding portion holding the blocking member at a position where the blocking portion blocks the opening.
4. The vehicular door lock device according to claim 1 , further comprising
a sub-base connected to the base portion from an inner side of the housing and fixing the latch to the base portion, wherein
the sub-base has a pressing portion pressing the blocking member against the base portion.
5. The vehicular door lock device according to claim 1 , wherein
the base portion has a groove portion allowing the striker to enter therein,
the opening is formed in the groove portion, and
a dimension of the opening in a latch engagement direction parallel to a direction in which the latch engages with the striker is larger than a dimension of the opening in a direction orthogonal to both an insertion direction of the operation tool and the latch engagement direction.
6. The vehicular door lock device according to claim 1 , further comprising
a sub-base connected to the base portion from an inner side of the housing and fixing the latch to the base portion, wherein
the blocking portion has a pair of guide surfaces provided at positions sandwiching the slit, and
the sub-base has a pressing portion contacting a side of the blocking member opposite a side of the blocking member having the pair of guide surfaces to press the blocking member against the base portion.
