A suspension gear of a vehicle, such as an all terrain vehicle, has a structure with which an increase in the weight of a strut damper can be suppressed. A strut damper axis is disposed to be along an imaginary line formed by imaginarily interconnecting an intersection at which a vertical line passing through a grounding point of a wheel intersects an extension line of a lower arm and a connection point at which the strut damper is connected to a vehicle body. A reaction force from a road surface is input to the strut damper substantially along the strut damper axis. Since no bending force is exerted on the strut damper, the strut damper can be made smaller in size, and the strut damper can be made lighter in weight.
