Creation Instructions (5) and insert each engaging protrusion 18 into the corresponding engaging recess 丨 4. Next, the rotary shaft 21 is inserted into the ring 41 and the ring 41 is placed on the main rotor 12. Then, the rotary shaft 21 is inserted into the insertion hole 8 of the cover body 7 in which the annular groove 9 is located on the lower side, and the peripheral wall 4 is inserted into and fitted into the 瓖 -shaped groove 9. When the peripheral wall 4 is inserted and fitted into the annular groove 9 as described above, the O-ring 41 is deformed by being pressed by the cover body 7, thereby sealing the space between the cover body 7 and the rotating shaft 2 1. In this state, a state in which the viscous fluid 3 丨 is filled is formed in the area (receiving recess 3) formed by the housing body 2, the lid body 7, and the ring 41. As described above, in a state where the cover body 7 is covered with the housing body 2, for example, the peripheral wall 4 and the cover body 7 are heat-sealed, and the space between the peripheral wall 4 and the cover body 7 is sealed. D is mounted in the state shown in Figure 1. Next, a method of attaching the gear 61 to the rotation shaft 21 will be described. In a state where the rotating shaft 21 of the slewing damper D assembled as described above is positioned on the upper side, the inner side surfaces of the engaging claws 6 3 of the gear 61 are gradually narrowed from the lower side to the upper side, and When the insertion hole 6 2 is inserted into one end of the rotary shaft 2, each of the engaging claws 6 3 is fastened to the rotary shaft 2 1, but the gear 6 1 is opened due to its elasticity, so the rotary shaft 2 1 can face the insertion hole. 6 2 Insert ° Furthermore, when the upper end of each engaging claw 6 3 is lowered to a position corresponding to the upper end of the notch 2 3, the gear 6 1 will be contracted due to its own elasticity.

Creation instructions (6) 1 As shown in the figure, each protruding engaging claw 63 will be inserted into the corresponding notch 23 and abut the upper edge of the notch 2 3, so that the The gear 61 is mounted on the rotation shaft 21 without falling off. Next, the operation will be described. Assemble by the method shown in FIG. 1, then use the mounting hole 6 a of the fixed arm portion 6 to install the swing damper D ′, and for example, engage the rack of the door leaf with the gear 61 to open the door leaf in an upright state. Next, the positional relationship between the engaging recesses 14 and the engaging protrusions 18 is in the state shown in FIG. 2. In addition, in FIG. 2, the direction in which the rotor 11 rotates clockwise is the closing direction of the door, and the direction in which the rotor 11 rotates counterclockwise is the opening direction of the door. As described above, when the door leaf is closed when the door leaf is opened, the door leaf starts to rotate in the closing direction due to its own weight. In the $ state in which the door leaf starts to rotate in the closing direction due to its own weight, the engaging protrusion 18 will enter the engaging recess 14, and the braking torque will be smaller than the braking torque of the main rotor 12, so The door leaf is turned in the closing direction while being braked, and the rotation speed is increased. And "in a state where the door leaf is closed by a predetermined angle (40 degrees) to accelerate the rotation of the door leaf", the engaging protrusion 18 will be engaged with the peripheral edge of the engaging recess Η, so that the sub-rotor 15 and the main rotor 12 rotate together. Therefore, the braking torque becomes larger, the sum of the braking torque of 1 and the braking torque of the auxiliary rotor 15 is closed, so the door leaf will be turned in the closing direction while being braked, and the engagement recess when the door leaf is opened is engaged with Position of protrusion 丨 8

Creation Note (7) The relationship is opposite to that when the door is closed, that is, in the second picture, the rotor 11 rotates counterclockwise. Therefore, 'the same as when the door is closed, the braking torque at the beginning of opening the door is small', and the door torque is increased after the door is opened by a predetermined angle (40 degrees). As described above, according to the first embodiment of the present invention, the main rotor i2 is made to rotate the rotor 11 by rotating with the rotating shaft 21 as a whole; and after the main rotor 12 is rotated by a predetermined angle, it is engaged with the main rotor 12 Since the sub-rotor 15 is integrally rotated with the main rotor 12, the initial braking torque when the housing i and the rotor are relatively rotated can be reduced. In this way, it is possible to slow down the movement of the braked body such as the door leaf without making it sound.

Creation instructions (9) Then, insert the rotation shaft 21 into the insertion hole 8 of the cover 7 with the annular groove 9 on the lower side, and insert the peripheral wall 4 Inserted and fitted into the annular groove 9. When the peripheral wall 4 is inserted and fitted into the annular groove 9 as described above, the O-ring 41 is deformed by being pressed by the cover body 7, thereby sealing the space between the cover body 7 and the rotating shaft 2 1. In this state, a region (receiving recessed portion 3) formed by the case body 2, the lid body 7, and the O-ring 41 is filled with the viscous fluid 31. As described above, in a state where the cover body 7 is covered on the housing body 2, for example, the peripheral wall 4 and the cover body 7 are heat-sealed, and the space between the peripheral wall 4 and the cover body 7 is sealed. Install it in the state shown in Figure 4. In addition, since the operation of the swing damper d of the second embodiment is the same as that of the swing damper D of the first embodiment, the description of the operation is omitted. According to the second embodiment of the present creation, except that the same effect as the slewing damper D of the first embodiment is obtained, the main rotor 12A and the sub-rotor 15A are arranged on a plane orthogonal to the axis of the rotation shaft 21 Therefore, this embodiment can be described as an example in which the main rotor 1 2, 12 and the secondary rotor 15 are formed by the protrusions (engagement protrusions 14A, 18) and the recesses (engagement recesses 14, = engagement). For explanation, it is also possible to provide protrusions at a predetermined interval in the circumferential direction of the main rotor and the sub-rotor, and move between the protrusions on the other side of the main rotor to engage with the aforementioned * main rotation; After rotating at a predetermined angle, the sub-rotor and the rotor are engaged to rotate integrally with the main rotor.

Creation Description (Effects of the Invention) As explained above, according to this creation, since the rotor is a main rotor that rotates integrally with the rotating shaft according to this creation; and the main rotor is scheduled to rotate here After the angle, the sub-rotor, which is engaged with the main rotor and rotates integrally with the main rotor, can reduce the initial braking torque when the housing and the rotor start relative rotation. Therefore, the movement of the braked body such as a door leaf can be slowed down without stopping it. Further, since the main rotor and the sub-rotor are disposed on a surface orthogonal to the axis of the rotation shaft, the swing damper can be made thin.
