Abstract
It is an object of the invention to improve utility in a suspension apparatus for a vehicle having an electromagnetic actuator and a hydraulic damper. In the suspension apparatus, a hydraulic damper is disposed between an electromagnetic actuator and a wheel-holding portion, and a cover tube is provided for accommodating a seal provided between a piston rod and a housing of the hydraulic damper. In the suspension apparatus according to the present invention wherein the hydraulic damper is disposed between the wheel-holding portion and the electromagnetic actuator, it is possible to effectively mitigate not only transmission of vibrations to the vehicle body from the wheel via the electromagnetic actuator but also transmission of vibrations to the electromagnetic actuator. Further, owing to the presence of the cover tube, entry of dust and the like into the hydraulic damper through the seal can be effectively prevented.
