Door latch device

A door latch device comprising:

• a base that has an insertion groove into which a striker is insertable;
• a fork that is mounted on a fork shaft disposed on the base, on one side of the insertion groove, the one side being one side in a direction intersecting with a direction in which the insertion groove extends, that is rotatable between a latching position for holding the striker and an open position at which the striker is releasable, and is biased in a direction from the latching position toward the open position by a biasing member;
• a claw that is pivotally supported by a claw shaft disposed on the base, on another side of the insertion groove in the direction intersecting with direction in which the insertion groove extends, and extending along the fork shaft, that is rotatable between an abutting position where the claw comes into abutment against the fork at the latching position and a non-abutting position where the abutment against the fork is released and the fork is allowed to be rotated by the biasing member;
• an opening lever that includes a fork restricting portion configured to restrict a rotation of the fork toward the open position and a claw actuating portion configured to rotate the claw from the abutting position to the non-abutting position, that is pivotally supported on the base on the other side of the insertion groove, and that is disposed spaced apart from the claw in an axial direction of the claw shaft;
• and
• a driving mechanism that rotates the opening lever from an initial position to a first rotational position spaced apart from the initial position, a second rotational position further away from the initial position than the first rotational position, and a third rotational position further away from the initial position than the second rotational position, wherein
• when the opening lever is at the initial position, the fork restricting portion allows the fork to rotate, and the claw actuating portion keeps the claw at the abutting position,
• a rotation of the opening lever from the initial position to the first rotational position causes the fork restricting portion to restrict rotation of the fork toward the open position,
• a rotation of the opening lever from the first rotational position to the second rotational position causes the claw actuating portion to rotate the claw from the abutting position to the non-abutting position, and
• a rotation of the opening lever from the second rotational position to the third rotational position causes the fork restricting portion to cease to restrict the rotation of the fork toward the open position, while causing the claw actuating portion to restrict rotation of the claw toward the abutting position, wherein
• the fork is mounted on the fork shaft integrally rotatably,
• a fork lever is mounted on the fork shaft integrally rotatably, and adjacently to the opening lever, in a manner spaced apart from the fork in an axial direction of the fork shaft, and
• the fork lever has a restriction receiving portion against which the fork restricting portion butts.
