A dust cover strike plate in a suspension mechanism having a dust cover disposed about a shock absorber and arranged radially inward of a coil spring, and being superimposed on an inner portion of an upper face of a lower spring support member, and includes an abutting face opposite to a lower end of the dust cover in an axial direction. The abutting face has an axial projection height from the lower spring support member that is varied in a circumferential direction corresponding to an incline angle of the lower spring support member to the center axis of the shock absorber so that the abutting face is arranged on a plane substantially perpendicular to the center axis of the shock absorber, with which the lower end of the dust cover comes into contact. A suspension mechanism equipped with the dust cover strike plate is also enclosed.
