<P>PROBLEM TO BE SOLVED: To provide a suspension device capable of preventing rapid variation of attenuation force when it is switched from rugged vibration suppression control to gate suppression control. Ž<P>SOLUTION: After control of a variable throttling mechanism 30 by a rugged vibration suppression control mode is completed, control of the variable throttling mechanism 30 by a rugged vibration suppression continuation control mode is started. In the control by the rugged vibration suppression continuation control mode, during when the variable stage number D<SB>a</SB>is coincident with the rugged vibration suppression stage number D<SB>g</SB>after the rugged vibration suppression control is completed, the variable throttling mechanism 30 is controlled such that the setting stage number D becomes the rugged vibration suppression stage number D<SB>g</SB>. Accordingly, when the control by the gate suppression control mode is performed after the control by the rugged vibration suppression continuation control mode is completed, the setting stage number D of the shock absorber 20 is already coincident with the variable stage number D<SB>a</SB>. Thereby, rapid variation of the attenuation force is not generated. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
