  • Publication number: 20190112847
    Abstract: In a door closed state, a first locking section of a first pole abuts a latch, and the latch is kept in a full-latch position. In addition, a second locking section of a second pole abuts the first pole, and the first pole is kept in an abutting state against the latch. When a door handle is operated, the second pole pivots, the first pole and the latch are unlocked, and a door opening operation is thereby permitted. An arm of moment that is generated around a first pole axis by a force exerted on the first locking section from the latch is shorter than an arm of moment around the first pole axis that generates a force exerted on the second locking section from the first pole.
