設けられている。In the dehydration operation,
When the rotation speed at startup increases and the rotation speed at stop decreases,
Parallel mode (in which the inner tub and outer tub of the washing machine are in phase and almost rigid translational motion) and conical mode (in which the inner tub and outer tub of the washing machine are almost rigid and sesame rubbing motion) Pass through two critical speeds. In particular, when the spin-drying operation is started after the washing or rinsing operation, the laundry is likely to be entangled and unevenly distributed in the inner tub, and there is often a large unbalance. Since this resonance causes a large resonance amplitude phenomenon, there is a problem that the conical mode having a high frequency is particularly difficult to pass due to its vibration form. In addition, in order to increase the capacity of the inner tank, it is necessary to narrow the gap between the outer frame and the outer tank in order to increase the size of the inner tank. For this purpose, there is a problem that the resonance amplitude needs to be reduced. In order to solve these problems, a damper for providing damping for reducing the resonance amplitude is provided.

Incidentally, in order to obtain a frictional force, the sliding member is provided with some pressing force against the hanging bar. In general, the pressing force is such that the inner diameter of the sliding surface is set to be slightly smaller than the outer diameter of the sliding surface of the mating member, and the pressing force is often caused by the elastic deformation of the sliding member. For this reason, there is a problem that the influence of wear due to sliding cannot be avoided, and it is difficult to maintain a constant pressing force in long-term use.

定力を保持できる。At the start of the spin-drying operation after the washing or rinsing operation, the laundry is easily entangled and tends to be unevenly distributed in the inner tub, and there is often a large unbalance due to the offset. For this reason, lowering the resonance amplitude by attenuation is indispensable for passing the resonance point, and the conical mode of the resonance phenomenon that is a problem is a vibration mode that performs miso-sliding motion commonly called,
The cylindrical body 2h performs a periodic up and down movement with respect to the spring receiver 2b. At this time, the sliding member included in the cylindrical body 2h also performs a vertical sliding motion with respect to the suspension rod, and the magnetic attraction between the lubricant containing the magnetic powder-containing lubricant and the suspension rod, which is a magnetic substance, is performed. Due to the pressing force of the sliding member against the hanging rod caused by the force, a sliding friction force is generated between the outer peripheral surface of the hanging rod and the inner peripheral surface of the sliding member, and acts as a vibration damping force. At this time, the pressing force is not caused by the tightening force caused by the elastic deformation of the sliding member but by the magnetic attractive force. Can hold.

Further, since the sliding surface is constantly lubricated by the lubricant contained in the sliding member in accordance with the sliding, the lubrication does not occur and the appropriate slidability is maintained.

In a cylindrical member having an internal groove, this stamping process is often difficult. However, since the sliding member of the present embodiment has a configuration divided in the axial direction of the hanging rod, it is not necessary to pay attention to the dimensional difference between the outer diameter of the hanging rod and the inner diameter of the sliding member, and it is easy to remove the shape. In addition, the design and manufacture are facilitated, and the cost can be reduced.
