PROBLEM TO BE SOLVED: To easily adjust rigidity of an elastic element in diametric and prying directions without enlarging device size. SOLUTION: In a suspension bush 10, a low-friction sheet 22 is applied to an inner surface of a slit-shaped hollow part 20 formed through from one end surface to the other end surface in an axial direction of the elastic element 16 in such a way that a cross sectional form in the diametric direction is extended to be thin and long in the circumferential direction. The low friction sheet 22 forms a pair of slide surfaces 24 of low friction resistance facing each other in the diametric direction in the hollow part 20. When a load is inputted in the prying direction, the hollow part 20 collapses in accordance with deformation of the elastic element 16 to cause the slide surfaces 24 to press each other. As the slide surfaces 24 slide to each other mainly in the axial direction with low friction resistance, outer circumferential parts and inner circumferential parts of the elastic element 16 are deformed to the hollow part 20 relatively in shearing directions (shearing deformation) to absorb the load in the prying direction.
