We proposed and designed a shock absorber with magnetorheological fluid that is a material that responds to an applied magnetic field and changes its apparent viscosity. We did a trial production and experiments about this MR shock absorber using a drop test. The drop test has the condition that the mass of a falling body is less than 40kg and the collision speed of the falling body is less than or equal to 2.5m/s. In this paper, result of the examinations of the shock absorber are reported about several subjects on the resisting force of the shock absorber, such as an effect of the applied electric current, an influence of the height of the falling body, an improvement of the resisting force by the applied electric. As the result of this study, it is obvious that this trial shock absorber is a semi-active one which can vary its resisting force corresponding with the variation of the mass of a falling body.
