Document Type and Number:
Japanese Patent JP5164731
Kind Code:
B2
Abstract:
A damper spring device is provided with a first spring and a second spring retained by a stopper in such a manner that the second spring is compressed by a preload. The preload on the second spring is greater than a preload on the first spring. The first spring and the second spring have load-deflection characteristics such that the first spring deforms when an axial load acting in the direction of compression of the first spring is not greater than a load at which a strand of the first spring is at least partially compacted and that the first spring and the second spring deform when the axial load is greater than the load at which the strand of the first spring is at least partially compacted.
