Latch device

1. A latch device, comprising:

a base plate;

an open lever rotatably attached to the base plate;

a biasing unit; and

an electric release unit to be installed in an electric release type latch device in which the open lever is operated by power and a manual release unit to be installed in a manual release type latch device in which the open lever is manually operated are configured to be selectively installed in the base plate, wherein

the open lever includes an action end portion configured to press a ratchet engaged with a latch and disengaging the ratchet from the latch,

the biasing unit biases the open lever in a direction in which the action end portion and the ratchet are away from each other, and

the manual release unit is provided with a manual release stopping unit to abut against a driven portion provided in the open lever in a case where the unit is installed in the base plate, so as to stop the open lever at a standby position,

the latch device is configured to be attached to any one of a trunk main body or a trunk lid forming a trunk room in a vehicle,

an operation handle facing an interior of the trunk room in a state that the trunk lid is closed is provided in the open lever,

a support member to abut against the operation handle at least in a state that the open lever is placed at the standby position and in a case where a pressing load is applied to the operation handle from the side of the trunk room, so as to support the operation handle is provided,

the operation handle is provided so as to move along a surface facing the trunk room in a case where the open lever is operated by the power or manually,

the operation handle is placed on a side of the trunk room with respect to the support member, and

the support member is provided so as to overlap with the operation handle in a direction orthogonal to the moving direction of the operation handle.

2. The latch device according to claim 1 , wherein the driven portion is provided between the action end portion and an operation portion and pressed by the electric release unit in a case where the electric release unit is installed, so as to operate the open lever by the power.

3. The latch device according to claim 1 , wherein the manual release stopping unit is provided in a case that constitutes the manual release unit.

4. The latch device according to claim 3 , wherein the case includes a connector configured to output a conduction signal.

5. The latch device according to claim 1 , wherein the electric release unit includes a worm wheel configured to press the driven portion so as to operate the open lever by the power, and

the worm wheel serves as an electric release stopping unit that stops the open lever at the standby position in a case where the worm wheel stops at a stop position.

6. The latch device according to claim 1 , wherein the operation handle includes a fitting portion to be fitted to the operation portion of the open lever, and a display portion extending in a operation direction of the open lever from the fitting portion, and

the display portion and the support member overlap with each other.

7. The latch device according to claim 1 , wherein the support member is a case that constitutes the electric release unit or a case that constitutes the manual release unit.

8. The latch device according to claim 7 , wherein the case includes a rib on a surface facing the operation handle.

9. The latch device according to claim 1 , further comprising:

a protector cover configured to cover the open lever in a state that the operation handle is exposed to an exterior, wherein the protector cover includes:

a reference surface configured to regulate a reference position serving as a border from the trunk room;

a protector surface extending along a periphery of the operation handle and protruding toward the inside of the trunk room with respect to the reference surface; and

an inclined surface connecting the reference surface and the protector surface.
