摘要:
A door closer device includes an active lever which, when it is in an abnormal state-with respect to a latch lever, automatically returns a door to a normal state by means of a door closing operation. An active latch which is pivotably supported by an active lever is freely rotatable in one direction, but is rotation regulated by an arm of an active pawl, i.e. a cancel lever, in the other direction. This prevents the latch lever from jumping over the active latch and causing an abnormal state in which the active latch swings wide with respect to the latch lever.
