A vehicle spat device includes; a variable support mechanism configured to support a spat serving as an aerodynamic member at an expanded position in front of a wheel and a retracted position separated from the expanded position; an impact relaxation mechanism configured to allow retreating operation accompanied by displacement of the spat based on input of an external force to the spat; and a drive mechanism configured to apply a drive force to the variable support mechanism to cause the spat to operate between an expanded position and a retracted position as an operating range. The impact relaxation mechanism allows the retreating operation of the spat supported at the retracted position to a retreating position positioned further closer to a vehicle body side than the retracted position.

A separation element is configured to separate a working chamber from a compensation chamber of a hydraulic anti-vibration module for mounting an engine on a vehicle body. The separation element includes a first duct extending between a first mouth and a second mouth. In embodiments, the first mouth is provided in a first face of the separation element and is configured to be fluidically connected to the working chamber, and the second mouth is provided in a second face of the separation element and is configured to be fluidically connected to the compensation chamber. In embodiments, the first mouth includes a plurality of openings.
