But’ because the rotor rotates in both directions and passes over the resistance part to another resistance part. The cause of the air passing through the shell is due to the "force" mixed into the shell. The reason for the different dull sounds is that when passing through the resistance part, the air ': the mountain compresses because it hits the resistance part. The radon is emitted, and a cracking sound is generated. Abnormal noise :: The higher the viscosity of the viscous fluid, the easier it is to produce the narrower gap between the rotor and the casing, the easier it is to produce the abnormal noise of 316256 5 M266386. This creation During assembly, the air mixed in the casing will not pass through the resistance part, so even if the rotor rotates in two directions, abnormal noise caused by the air mixed in the casing can be prevented. (Solution to solve the problem) It has the following aspects of creation: (1) The square-rotation damper of this creation includes: a casing; a viscous fluid, which is contained in the casing; a rotor, which is contained in the casing, and a part of which protrudes from the casing. The shaft portion is provided with a resistance portion of the above-mentioned viscosity = middle which can be moved inside the casing; the sealing member 'prevents the above-mentioned viscous fluid from leaking from the shaft II; The damper is provided with a plurality of the above-mentioned resistance portions extending radially from the above-mentioned ㈣, and the ㈣-resistance portion is provided with a protruding portion protruding from the circumferential direction of rotation / the front end of the output portion facing each other at a predetermined interval. Q π, M is large (2) The rotation damper as described in (1), 1 The gap between the shells is made larger than the resistance ^ ^. ρ is narrower than the above. 卩 〃 The gap between the shells is more ( 3) If the rotation damping of the (1) or (2) aspect is crying, the gap between the front end and the resistance part is made two. 'The gap between the protruding parts is longer.' Protrude towards it (4) As in the first aspect to the second aspect # The above-mentioned opposite protrusions are placed in front of her and niches, of which, shape. Make a shape that narrows towards the front end (effect of creation) 316256 6 M266386 According to this creation, since a plurality of radial extensions from the shaft part = force ° 卩, and the resistance part is provided with a protrusion toward the rotation circumferential direction = large out part 'simultaneously' the front end of the protruding part Phased at a predetermined interval, so during assembly It can make the air mixed in the casing move at the rear end of the protruding part that generates negative pressure at any time, and it won't go further. Even if the rotor rotates in two directions, it can prevent the air from generating abnormal noise. The gap between the outer part and the case is made narrower than the gap between the resistance part and the second part. Therefore, when the resistance part rotates, the negative pressure is easy to mix with the middle part of the outer part of the rear part of the outer part. The protruding part moves. The milk is concentrated in this case. Even if the rotor rotates in both directions, the air may cause abnormal noise. It prevents the gap between the two front ends of the Γ and the resistance part due to the inward movement of the housing. Larger. The gap between P is even more mixed with the air in the shell. When the rotation of the mouth is reversed, the other side.亀 Easy to move from the-side of the opposite protruding part to * = 吝 Even if the rotor rotates in both directions, it can prevent the occurrence of abnormal noise caused by mixing into the outside and inside. The shape of the front end of the protruding part is narrow when it enters the outside and the inner part is narrow. Therefore, the air volume wA is made to shrink toward the rear end of the protruding part in the rigid direction. The negative pressure part of the mouth P knife (located on the upstream side of the outlet of the resistance king point) is discharged. 316256 7 M266386 on the upstream side of the reversing day π So the rotor reverses the reversing day, and the $ gas mixed into the casing can move smoothly.

In the structure of her example, the bearing portion 16 is provided on the housing η, the recessed portion 33 is provided on the shaft portion 32, and the rotor 31 is rotatably supported; however, if the recessed portion is provided on the housing, the bearing portion is provided on the shaft In the rotary damper of the embodiment, the outer shell includes a housing η, and the housing portion is provided with a silicone oil 21 in the housing U. A shaft of the rotor 31 is provided on the cover 41. The through hole 42 through which the portion 32 penetrates, and then the ring 5 5 prevents the silicone oil 21 from leaking between the cover 41 and the shaft portion 32 However, the structure of the rotary damper can be designed as follows: a t-receiving portion of the oil is provided on the cover, a through-hole penetrating through the shaft portion of the rotor is provided on the casing, and the silicone oil is prevented from passing through the casing and the casing by 0%. The structure leaked between the shaft portions. In addition, in the embodiment, a plurality of resistance portions are provided as two resistance portions, but it may also be set as two or more resistance portions 36, or even three resistance portions 36. The resistance portion 36 and the shaft portion 32 are formed: The shaft portion and the resistance portion can be separately formed, for example, a structure that rotates integrally by utilizing the angular relationship. The viscous fluid used in your known example is silicone. Oil magic, but it can also be used, 'he viscous fluid with the same function, such as lubricating oil, such as [Schematic description], Figure 1 is a cross-sectional view of the rotary damper of the first embodiment of this creation 316256] 3 M266386 Figure 2 is a perspective view of the rotor shown in Figure 1. Fig. 3 is an operation explanatory diagram. Fig. 4 is a plan view of a rotor constituting a rotary damper according to a second embodiment of the present invention. Key component symbols]
