ELASTIC SHEET AND SUSPENSION APPARATUS

摘要

An elastic sheet includes: a seating portion by which the coil spring is supported and which has a circular arc shape in a view from the axial direction, one circumferential side of the seating portion being a side of entry of the coil spring; and a pair of sidewall portions extending from respective width-wise opposite ends of the seating portion toward the coil spring side, at least one of the sidewall portions has a wire contact surface that contacts a wire forming the coil spring and an inclined surface inclined so as to approach the spring bearing as the inclined surface extends widthwise outward from the wire contact surface, and a radius of curvature of the wire contact surface at least at a side closest to the inclined surface is smaller than a radius of the wire.

1. An elastic sheet interposed between a coil spring that is provided in a suspension apparatus and that extends in an axial direction of the suspension apparatus and a spring bearing that supports the coil spring,
the elastic sheet comprising: a seating portion by which the coil spring is supported and which has a circular arc shape in a view from the axial direction, one circumferential side of the seating portion being a side of entry of the coil spring; and a pair of sidewall portions extending from respective width-wise opposite ends of the seating portion toward the coil spring side, wherein at least one of the sidewall portions has a wire contact surface that contacts a wire forming the coil spring and an inclined surface that is inclined so as to approach the spring bearing as the inclined surface extends widthwise outward from the wire contact surface, and a radius of curvature of the wire contact surface at least at a side closest to the inclined surface is smaller than a radius of the wire.
