摘要 <p><P>PROBLEM TO BE SOLVED: To provide a door closing device capable of suppressing rapid rotation of a door by exerting braking force earlier than ever in the closing of the door, without causing upsizing of the device. <P>SOLUTION: When a door 3 is closed, a body-to-be-captured 31 of a device-to-be-captured 7 provided on the door 3 is captured by a door arm 20 provided in a door frame 2 and drawn to forcedly guide the door 3 to a door-closed state. A guide groove 22 is formed in the undersurface portion of the door arm 20. The guide groove 22 comprises a linear acceptance portion 22a for accepting the body-to-be-captured 31, a terminal end 22b where the body-to-be-captured 31 is positioned in the closing of the door 3, and an intermediate portion 22c which is smoothly curved from the acceptance portion 22a and elongated to the terminal end 22b. The acceptance portion 22a is positioned on the side of the door 3 with respect to the terminal end 22b in the rotational direction of the door arm 20. <P>COPYRIGHT: (C)2012,JPO&INPIT</p>
