PROBLEM TO BE SOLVED: To achieve miniaturization of a door closer device.SOLUTION: A door closer device comprises a planetary gear mechanism 33 including: a sun gear 35 supported on a base plate by a support shaft 34; a planetary gear 36 revolvably engaging with the sun gear 35 while being rotated; a closing lever 38 pivoted by the support shaft 34, pivoting the planetary gear 36, and directly or indirectly linked to a latch 7; and a sector gear 39 pivoted by the support shaft 34, having an external tooth gear 391 engaging with an output gear 322 rotatable by power of a motor on the outside of the periphery of a fan shape, and having an inner tooth gear 392 engaging with the planetary gear 36 on the inside of the periphery. The planetary gear 36 revolves while being rotated and the closing lever 38 swings around the support shaft 34 in conjunction with swinging of the sector gear 39 on the basis of rotation of the output gear 322, thereby moving the latch 7 from a half-latch position to a full-latch position. |
