PURPOSE: A haptic actuator using a spacer and rheological fluid and a haptic providing method using the same are provided to offer haptics by transferring a variable resistance applied to a spacer according to changes in the viscosity of rheological fluid. CONSTITUTION: A haptic actuator comprises rheological fluid(100), a standing cylindrical or polygonal barrel-shaped case(200), an application unit(300), a spacer(400), and an elastic unit(500). The viscosity of the rheological fluid changes by a magnetic field or electric field. The case accommodates the rheological fluid. The application unit applies a magnetic field or electric field to diversify the viscosity of the rheological fluid. The spacer, having the same shape as the cross section of the case, is located inside the case and transferred in the case. The elastic unit connects the bottom of the case to the spacer. The resistance of the rheological fluid passing through holes(410) of the spacer, which changes according to the viscosity of the rheological fluid, is delivered to a user.
