A suspension device for vehicles, the suspension device comprising: a damper disposed between a wheel of a vehicle and a vehicle body of the vehicle and configured to extend and retract between the wheel and the vehicle body, a knuckle configured to support the wheel; a trailing arm connected to the knuckle and extending in a vehicle's longitudinal direction; and a connecting part configured to connect a front portion of the trailing arm in the vehicle's longitudinal direction to the vehicle body; a shaft configured to pivotably support an end of the damper; and a bush including a cylindrical elastic member fitted onto an outer circumference of the shaft and interposed between the shaft and the damper, wherein the bush is fitted onto the outer circumference of the shaft that connects a lower end of the damper to a rear portion of the trailing arm in the vehicle's longitudinal direction, characterized in that an axis of the damper is inclined relative to the vertical direction when viewed in the vehicle's longitudinal direction and an axis of the bush is disposed along a line of intersection between an imaginary first plane and an imaginary second plane, or along a line parallel to the line of intersection, the first plane being orthogonal to the axis of the damper when a stroke position of the wheel is a first position relative to the vehicle body in a vertical direction of the vehicle body, the second plane being orthogonal to the axis of the damper when the stroke position of the wheel is a second position different from the first position, wherein the axis of the damper is inclined inward in a vehicle width direction toward a top of the vehicle and the axis of the bush is inclined frontward in the vehicle's longitudinal direction toward an inside in the vehicle width direction or the axis of the damper is inclined outward in a vehicle width direction toward a top of the vehicle and the axis of the bush is inclined rearward in the vehicle's longitudinal direction toward an inside in the vehicle width direction. a damper disposed between a wheel of a vehicle and a vehicle body of the vehicle and configured to extend and retract between the wheel and the vehicle body, a knuckle configured to support the wheel; a trailing arm connected to the knuckle and extending in a vehicle's longitudinal direction; and a connecting part configured to connect a front portion of the trailing arm in the vehicle's longitudinal direction to the vehicle body; a shaft configured to pivotably support an end of the damper; and a bush including a cylindrical elastic member fitted onto an outer circumference of the shaft and interposed between the shaft and the damper, wherein the bush is fitted onto the outer circumference of the shaft that connects a lower end of the damper to a rear portion of the trailing arm in the vehicle's longitudinal direction, an axis of the damper is inclined relative to the vertical direction when viewed in the vehicle's longitudinal direction and an axis of the bush is disposed along a line of intersection between an imaginary first plane and an imaginary second plane, or along a line parallel to the line of intersection, the first plane being orthogonal to the axis of the damper when a stroke position of the wheel is a first position relative to the vehicle body in a vertical direction of the vehicle body, the second plane being orthogonal to the axis of the damper when the stroke position of the wheel is a second position different from the first position,
