Title: Spring for suspension device for vehicle
Inventor: OGISO HIROYUKI
IPC: F16F1/12
Filed: 2018-03-07
Abstract: To disclose one embodiment of a spring for a suspension device which can suppress the early damage of a spring part constituted of a metal-made wire rod.SOLUTION: A difference between the hardness of a seat part 3 and the hardness of an adhesive (adhesive layer AD) is larger than a difference between the adhesive (adhesive layer AD) and a coated layer 2B. Normally, since exfoliation is liable to occur at a boundary face having a larger difference of the hardness more than the other boundary face, the boundary face between the seat part 3 and the adhesive layer AD is liable to be exfoliated from the boundary face between the adhesive layer AD and the coated layer 2B. Therefore, even if the adhesive layer AD is exfoliated, the coated layer 2B can be maintained in a state of being coated with the adhesive layer AD, and thereby it can be suppressed that the coated layer 2B is damaged in an early stage. Also, since it is suppressed that a metal-made wire rod 2A is damaged in an early stage, the early damage of a spring part 2 can be suppressed.SELECTED DRAWING: Figure 3
