<p>PROBLEM TO BE SOLVED: To provide a door closer which is set in a hinge door, and generates a necessary door closing force.SOLUTION: This door closer has: a reciprocation body (12) which is continuously arranged at a hinge (A), and reciprocates in a horizontal direction accompanied by the opening motion and the closing motion of a door; a first rack (14) attached to the reciprocation body; a rotating shaft (16) which is attached to the door so as to be rotatable, and has a first pinion (18) which is engaged with the first rack; and door-closing energization force accumulation means (23) which is continuously arranged at the rotating shaft, pressed accompanied by the rotation of the rotating shaft accompanied by the reciprocation motion of the first rack, and accumulates a door-closing energization force. The door-closing energization force accumulated in the door-closing energization force accumulation means is transmitted to a hinge via the rotating shaft, the first pinion and the reciprocation body, and the hinge is driven to a door-closing direction.</p> |
