る。2. Description of the Related Art Generally, a damper device relating to a toilet seat / toilet lid has a large difference in weight between a toilet seat covered with a toilet seat cover and a toilet lid, which is a simple cover, with a built-in heater. Therefore, regarding opening / closing of the toilet seat / toilet lid, each hinge is provided with an independent rotating shaft and separately connected, and the rotating speed is controlled separately. As these damper devices, a pressure oil damper that utilizes a braking force generated by an oil resistance that is pressurized when passing through an orifice,
There is a grease shearing damper that utilizes the braking force by the shear resistance of high viscosity grease applied to the outer surface of the rotor and the inner surface of the case.

い。The pressure type oil damper requires a strong seal structure that can withstand the force of the forced closing operation of the toilet seat / toilet lid, while oil leaks occur when oil leakage occurs. The damper action does not work, and the toilet seat / toilet lid that rotates in the closing direction collides with the toilet bowl, which causes an unpleasant sound and causes damage to the toilet bowl. Therefore, a strong structure is required for oil leakage, and the structure is complicated, the number of parts is increased, and the cost is inevitable.

ストアップを招く。On the other hand, the grease shearing type damper does not need to pressurize the grease, has a simple structure, and has a simple sealing structure against leakage of grease. Further, even if there is some leakage of grease, since it is not pressurized, the damper function is not suddenly lost unlike the pressure oil damper, and there are few factors that affect the product life. Therefore, as a usual solution, it is possible to use independent grease shearing type dampers for the toilet seat and the toilet lid, respectively.
The number of parts, the installation space, the installation work, etc. increase, which leads to an increase in cost.

The cylindrical case 12 is fixed to a toilet (not shown) by inserting a bolt into the bolt hole 19a. The outer diameter of the bearing boss 18, which is the connecting shaft of the outer insertion rotor 15, is coupled and fixed to the hinge of the toilet seat. The connecting portion 20c of the insertion rotor 20 is fixed to the hinge of the toilet lid. When the outer seat rotor 15 is rotated by rotating the toilet seat around the hinge, the grease enclosed in the gap between the cylindrical case inner wall 12b and the braking outer surface 17a and the outer surface 13b of the fixed cylinder 13 are opposed to each other. The shearing resistance is generated in the grease enclosed in the gap between the braking inner surface 17b and the braking force, and the toilet seat can be slowly closed by its own weight.

Shear resistance is generated in the grease enclosed in the gap between the outer surface of the braking shaft portion 20a, which acts as a braking force, and the toilet lid can be slowly closed by its own weight.

トルクを得る手段として径方向の腕の長さの違いによる
トルク差を利用することができる。Since the toilet seat has a built-in heater and the like, it is heavier and has a larger turning torque than the toilet lid. In order to cope with this torque difference between the toilet seat and the toilet lid, the toilet seat is connected to an extrapolation rotor 15 in which a braking cylinder 17 having a large surface area and exerting a strong braking action by grease shearing resistance is provided in series. On the other hand, an insertion rotor 20 in which a braking shaft portion 20a, whose surface area is set smaller than that of the braking cylinder 17 to reduce the braking force, is continuously provided, is connected to the toilet lid. As a result, the closing speed due to the own weight of the toilet seat / toilet lid can be made approximately the same. Further, in such a double shaft concentric structure, since the outer insertion rotor 15 for the toilet seat performs the braking action on the outer side and the inner insertion rotor 20 for the toilet lid acts on the center side, different rotational torques are generated. As a means for obtaining it, a torque difference due to a difference in the length of the radial arm can be used.

The same members as those in the first embodiment are designated by the same reference numerals. And the description is omitted. Since the grease shearing type damper device utilizes the adhesive property of high-viscosity grease, the braking force increases as the surface area of the portion where the cylindrical case and the rotor face each other increases.

From the above, a fixed cylinder 33 and a hollow shaft 34 are projected, and a hollow portion 40e is recessed in the center of the braking shaft portion 40a of the insertion rotor 40, and the outer surface of the hollow shaft 34 and the inner surface of the insertion rotor hollow portion 40e are The gap 14 is filled with grease 14. As a result, the surface area involved in grease shearing is increased, and the braking force on the toilet lid can be increased. Similar to the first embodiment, the outer wall 32a of the cylindrical case 32 is provided with a mounting seat 19 having a fixing bolt hole 19a.
