3はスムーズに開放する。By the rotation of the door 3, the rotor 16 of the second hinge 10b comprising the hinge with a built-in damper shown in FIG. 3 rotates in the direction shown by the arrow in FIG. At this time, since the circumferential groove 33 formed in the rotor 16 is in a state of communicating the chamber A and the chamber B, the hydraulic oil in the chamber B smoothly flows into the chamber A, and the rotational resistance applied to the rotor 16 is small. The door 3 opens smoothly.

ア3に制動力が与えられる。When the door 3 reaches the terminal region of the opening movement, as shown in FIG. 3 (II), the circumferential groove 33 formed in the rotor 16 blocks the communication between the chamber A and the chamber B. The viscous fluid flows from the leak gap 25 formed between the outer peripheral surface of the damper blade 24 and the inner peripheral surface of the damper chamber 20 to the chamber A. For this reason, the damper blade 2
4 is given a relatively large rotational resistance, and a braking force is applied to the door 3.
【0039】このため、ドア3が勢いよく開放されたと

Is released, the weight of the door 3 is applied to the contact portion between the cam surfaces 46a and 47a in the third hinge 10c, so that the cam surface 46 on the movable hinge member 41 side.
a and 47a are cam surfaces 46a on the fixed hinge member 42 side,
Moving along 47a, the door 3 rotates in the closing direction.

軸方向溝31aの浅溝部に向けて移動する。At this time, the needle valve 32b on the chamber B side shown in FIG. 3 (III) moves to the deep groove portion of the axial groove 31b,
The viscous fluid in the chamber flows from the gap 27 formed between the outer peripheral surface of the rotor 16 and the inner peripheral surface of the protruding portion 26 to the chamber B, and the flow of the viscous fluid causes the needle valve 32a in the chamber A to move in the axial groove 31a. Move toward the shallow groove of.
