In this study, damping force properties of damping force variable damper using magnetic functional fluid which consists of nanometer-size and micrometer-size magnetic particles, poly-alpha-olefine, smectite and alpha-cellulose are investigated experimentally. It is shown that the magnetic functional fluid becomes light by containing the alpha-cellulose. Then the damping force of the damper using the magnetic functional fluid becomes large by containing the alpha-cellulose.
