A vehicle shock absorber includes a first shock absorbing unit and a second shock absorbing unit. The first shock absorbing unit is able to reduce the generation of the damping force and quickly replenish oil through a first one-way valve during the compression operation, and generate sufficient tensile side damping force when performing the stretching operation. The second shock absorbing unit is able to generate a sufficient compression side damping force through a second one-way valve during the compression operation, and reduce the generation of the damping force during the stretching operation to quickly replenish oil. Because the second shock absorbing unit provides sufficient compression side damping force, it is unlikely to encounter a bottoming situation and thus there is no need to configure a stop block, thereby not only saving the cost, but also avoiding the generation of cupping sound. In addition, the second shock absorbing unit is able to quickly replenish oil when performing the stretching ope
