The large-diameter portion 4 2 and the small-diameter portion 4 4 are provided at their centers with through-holes 4 5 ′, and the supporting shafts 16 of the external body 12 are rotatably penetrated. Therefore, since the width of the protrusion 41 is narrower than the width of the receiving groove 34, the protrusion 41 can move in the axial direction with respect to the rotating body 31, and can rotate a predetermined angle with respect to the rotating body 31. Next, an example of a method of assembling the damper D will be described. First, the middle-diameter portion 36 is inserted into the small-diameter portion 37 of the rotating body 31 through the O-ring 71 'and the hole 2 3 of the outer cover 21 is simultaneously inserted, so that the 0-ring 71 is abutted on the middle-diameter portion. 3 6 The large-diameter portion 3 2 on the outside, and the outer cover 21 is brought into contact with the large-diameter portion 3 2 through the 0-ring 7 1, and the O-ring 7 丨 and the outer cover 2 丨 are mounted on the rotating body 3 Next, a predetermined amount of the viscous liquid 61 is poured into the receiving recess 14 of the housing body 12, and then the through-hole 45 is penetrated through the support shaft 6, and the cam body 41 is inserted into the receiving recess 14. Then, the coil spring 51 is inserted into the accommodating recessed portion 14 so that one end (lower) side thereof abuts against the large-diameter portion 42 of the small-diameter portion 4 4 of the cam body 41.

Description of the invention (5) The diameter portion 32 is inserted into the receiving recess 14. When the large-diameter portion 32 is inserted into the receiving recess 14 in this way, it is inserted in a manner corresponding to the protrusion 4 3 corresponding to each receiving groove 34, so that the protrusion 43 of the cam body 41 can be inserted (received in). Containment trench 34. Then, after the fastening portion 2 2 of the outer cover 21 corresponds to the fastening hole 18 of the housing body 12, the outer cover 21 is stacked toward the housing body 12 side, and each fastening portion 2 2 is buckled. It can be assembled as shown in Figure 4 by matching the way with the corresponding buckle holes 18. When assembled in this manner, the air in the receiving recess 33 of the rotating body 31 is discharged through the through hole 35, and the air that has not been exhausted remains in the receiving recess 33 or the through hole 35. The thus-assembled damper D is sealed between the outer cover 21 and the rotating body 31 by the 0-ring 71, and the seal between the housing body 12 and the rotating body 31 is formed by fitting. However, the viscous liquid 61 may leak from between the housing body 12 and the rotating body 31. If the liquid body 1 is to be more completely sealed, the housing body 12 and the outer cover 2 1 may be heat-sealed or sealed. A 0-ring seal is arranged between the housing body 12 and the outer cover 21. Next, the operation will be described. It is explained that the damper D is used to brake the opening and closing of the door lintel, and the door lintel is turned from the closed state to the open state by rotating from the vertical state to the horizontal state. Then, in the closed state of the lintel, the coil spring 51 is brought into a state of maximum extension, and the two cam surfaces 15a and 42a are brought into full contact with each other.

Description of the invention (6) First, the closed state of the lintel when it is locked is released, and then when the lintel is turned, there will be a gap (gap) between the side wall of the receiving groove 34 and the protrusion 43. The door lintel is not braked, but rotates while accelerating by its own weight, so that the protrusion 4 3 is abutted to the side wall of the receiving groove 34. Then, when the protrusion 43 abuts against the side wall of the receiving groove 34, the lintel, the body 3 1 ^ 3 1 and the cam body 4 1 all start to rotate, so a viscous liquid 6 1 between the housing body 12 and the rotation occurs. Viscous resistance. And rotates by the cam body 41 along the cam surface 42a along the cam surface 51a of the cam surface 51a and * compresses the helical spring yellow 5 1 '. Therefore, the compression coil spring opening force is generated. By its own weight, while accelerating, it is opened while being braked as described above. Slowly open the bumps. According to one embodiment of the present invention, because the cam portion is accommodated in the rotation, Zhao 41, Spiral Elite 51 (made of elastic members) The power-giving mechanism) is closed in Zhao 31, and the damper D can be miniaturized. The cam body 41 can be rotated by a predetermined angle with respect to the rotating body 31. Therefore, the light η β is opened and the brake is accelerated after the opening speed is accelerated. Therefore, self-jealousy can be turned on even by the self-weight. 42 technology, so that the cam portion 15 and the cam body 41 are provided with two cam surfaces 1 5 a, and the force_outside cam body 41 does not tilt the cam portion 15, that is, because no additional knowledge is required . Shili can make the cam body 41 turn, so the braking torque can be the same as above. In the form of the turtle, it is explained that the coil spring 5 1 can be used as the elastic member for other elastic members that can perform the same function, such as plate jing. .
577963 五、發明說明(7) 上述說明係為使凸輪體4 1可相對於轉動體3 1轉動預定 角度之例,但亦可使凸輪體4 1不能相對於轉動體3 1進行轉 動,而在當轉動體3 1對外殼1 1開始轉動時,直接施加制 動。 上述說明係凸輪部1 5及凸輪體4 1分別設有兩嗰凸輪面 1 5 a、4 2 a之例,但凸輪面1 5 a、4 2 a亦可為一個,亦可為三 個以上。 [發明之功效] 如上述,依據本發明,由於轉動體中收容有凸輪部、 凸輪體、彈壓構件(彈壓構件制動賦予機構),而使阻尼器 得以小型化。 然後,由於使凸輪體可相對於轉動體轉動預定角度, 故可藉由在門扉之開啟速度加速之後施加制動,因此自體 重量較輕的門扉,亦可藉由該自體重量開啟。 而且,由於凸輪部及凸輪體分別設有二個以上之凸輪 面,故藉由凸輪體不會對凸輪部形成傾斜,而可使制動扭 矩同樣地增加。577963 V. Description of the invention (7) The above description is an example of enabling the cam body 41 to rotate a predetermined angle with respect to the rotating body 31, but it is also possible to prevent the cam body 41 from rotating relative to the rotating body 31, and When the rotating body 31 starts to rotate against the housing 11, the brake is directly applied. The above description is an example in which the cam portion 15 and the cam body 41 are provided with two cam surfaces 15 a and 4 2 a, respectively. However, the cam surfaces 15 a and 4 2 a may be one or more than three. . [Effect of the Invention] As described above, according to the present invention, the cam body, the cam body, and the urging member (the urging member brake applying mechanism) are contained in the rotating body, so that the damper can be miniaturized. Then, since the cam body can be rotated by a predetermined angle with respect to the rotating body, the brake can be applied after acceleration of the opening speed of the lintel, so the lintel with a lighter weight can also be opened by the self weight. In addition, since the cam portion and the cam body are provided with two or more cam surfaces, the cam body does not incline the cam portion, and the braking torque can be increased similarly.
