  • Patent number: 11236533
    Abstract: The present invention aims to reduce the operation noise of a latch device for a vehicle trunk lid when the lid is opened. A latch device for a vehicle trunk lid includes: latch 16 that is engaged with a striker; ratchet 18 that is engaged with latch 16; opening lever 43 that causes ratchet 18 to rotate in a direction in which ratchet 18 is disengaged from latch 16; output member 39 that rotates opening lever 43 in the release direction. Opening lever 43 is rotatable between an unblocked position where it is rotatable in the release direction and a blocked position where it is prevented from rotating in the release direction by colliding with the output member. When driven and rotated, output member 39 abuts against opening lever 43 that is in the unblocked position and rotates opening lever 43 in the release direction to the blocked position, and opening lever 43 is further rotated a predetermined angle by colliding with output member 39 in the blocked position.
