',,,: After holding the flange portion 丨3, 丨5, the Q-shaped ring is held on the lower side of the "driven rotating member outside the outer circular cymbal 14" i, and is used as a guide center. 5 Insert the guide inside the inner cylindrical wall i 6 to insert the two fixed support members 21. When the π is inside the disk, the viscous fluid 51 and the air are driven to rotate: the fixed branch member 11 21 ^, 1, 冓 117 enters between the inner cylindrical wall 16 and the central axis. The air moves faster than the viscous fluid 51, so the air enthalpy remains in the accommodating portion 41 of the driven rotating member η and the fixed body. When the lower side of the structural member 11 formed by the support member 21 is inserted into the fixed support member 21, the outer cylindrical wall 23 is inserted in such a manner that the flange portion is rotated in the manner of the core member. π, j ' 〇 裱 31 system seals between the outer soil 23 and the inner cylindrical wall 24, and the workpiece 11 and the fixed support member 21 can be rotated relative to each other (4) and the rotating structure is further As shown in Fig. 4, the inner cylindrical wall 317]12 12 1269845 16 ' is passed through the fastening projection 18, and the front end abuts on the fusion limit. At 19 o'clock, the snap projection 18 enters the buckle surrounding groove 26, and the snap projection 18 is fastened to the buckle circumferential groove 26 as shown in the figure. Then, as shown in Fig. 4, the rotating member will be driven.丨 [Assembled in the shape of the solid-twisted dentate member 21, the current flows through the heating sheet η to heat it, - as shown by the two-point chain line, the upper end portion of the inner cylindrical wall 1 β enters the heating sheet. In the recess c of the crucible, the heating piece η is pushed down, whereby the upper end portion of the inner cylindrical wall Lu 16 is melted and closed, and after the heating sheet n is cooled by gas, the heating sheet is removed, and the heating sheet is removed. The rotation damper of the state shown in Fig. 6 completes the assembly work. Next, one of the installations of the rotary damper will be installed, as shown in Fig. 6, on the hole of the board to be mounted E, that is, in an inch. The bottom wall 22 of the support member 21 has the same circular shape, and the rotary damper D is attached to the mounted plate by using a hole having a notch that can be used to insert the mounting portion 27 into the outer circumferential position of the 18-degree opposite direction. Next, 'the action of the rotary damper D will be explained. First, when the rotating member is driven丨When rotating, the viscous fluid 51 between the driven member U and the fixed branch _ _ is also called the viscous fluid 51, and the brake is driven to rotate the rotating material. The gear L of the driven rotating member n is referred to as a transfer or the like, and the L-wheel and the tooth are gently inclined. (4) The member 11 is placed as described above to be used in accordance with an embodiment of the present invention. The inner cylindrical wall 317112 1269845 16 (opening) that drives the rotating structure to ventilate the central portion of the valley 41 will drive the rotating member u and the fixed supporting member to form a closed inner cylindrical wall 16 (opening) Therefore, the redundant air stays in the accommodating portion 41, making assembly easier, and the air w is viscous in the viscous fluid 51, and the torque is kept constant twice, and then mixed, and then assembled. The driving rotating member n and the fixed supporting member are provided with a space restricting portion (welding limit 19) in the driven rotating member n to restrict the driven rotating member u and the fixed supporting member. ! 1 p The interval between the rotation axis directions of the rotation, because the interval between the driven rotating member core and the = support member 21 does not fluctuate, and the sealing can be used to seal the inner cylindrical wall 16 (opening) The means is sealed so that the inner cylindrical wall 16 (opening) can be surely closed to prevent the viscous fluid 51 from leaking out of the inner cylindrical wall 16 (opening). Further, a center shaft 25 is provided at the center of the fixed support member 21, and the movable rotating member 11 is provided with an inner cylindrical wall 16, which is in the middle of the cylindrical wall 丨β.
