PROBLEM TO BE SOLVED: To buffer a shock and prevent a bound of a door when it stops at its stationary position with the shock. SOLUTION: The door (1) is provided with a pin (3). A braking device body (2) is mounted on a position opposite to the pin (3) in the stationary position of the door (1). The braking device body (2) is provided with a spindle (5) which rotates while being braked by receiving a fluid resistance, and is provided with an arm (8) fixed to the spindle (5). A holding groove (19) opening toward the front end of the arm (8), and locking pieces (20), (21) are provided at the front end of the arm (8). When the door (1) comes closer to the stationary position, the pin (3) hits the locking piece (21) and enters into the holding groove (19) while rotating the arm (8). At this time, since the rotation of the arm (8) is braked by the spindle (5), the shock is buffered. Further, since the pin (3) enters into the holding groove (19) of the arm (8), the bounce of the door is prevented. COPYRIGHT: (C)2004,JPO&NCIPI
