In addition, the restoring force of the spring acts in the direction of the opening of the lid, so that it can be easily lifted, but when fully lifted, rocking can be generated with a "click" sound.

Conventionally, in the case of the AXIS DAMPER type with a variable torque / one-way function, there is no device that reduces the weight in the direction of lifting the lid, making it difficult to open the lid as well as lifting the lid. When released, that is, the damper effect is insufficient when the switch from the lifting direction to the closing direction has a problem that a "click" sound occurs in the final closing portion (CLOSE END).

Conventionally, the method of using the compression spring and the shaft damper, respectively, has a problem that the torque distribution management becomes difficult when the elastic force of the compression spring and the damping force of the shaft damper are not united. Is composed of a single housing, the housing is large in order to withstand the internal pressure because it accepts a lot of force values in one housing. There was a problem such as being done.
