A vibration-proof structure for axle beam of a motor vehicle has an axle beam composed of a long cylindrical body of a letter U-shaped section opening downwards, which is disposed in the width direction of the motor vehicle. Axles are provided at both ends of the long cylindrical body, a stabilizer bar is disposed in the center of an interior of the long cylindrical body so as to connect the both ends of the long cylindrical body, and at least one vibration-proof rubber body is interposed between an inner wall of the axle beam and the stabilizer bar from the underside thereof in elastic contact therewith. The vibration-proof rubber body has an engaging member for engaging the vibration-proof rubber body with the axle beam or the stabilizer bar. The vibration-proof rubber body can be easily installed within the axle beam after the assembling of the axle beam and the stabilizer bar. The vibration-proof rubber body inserted between the axle beam and the stabilizer bar can be certainly engaged with the axle beam or the stabilizer bar by means of the engaging member. Accordingly, the vibration-proof rubber body is prevented from dropping due to vibration or the like.
