PROBLEM TO BE SOLVED: To attain with a simple structure enough displacement in a direction perpendicular to an axial direction, with respect to an input in an axial direction. SOLUTION: A toe collect bush 1 has an inner cylinder 2, an outer cylinder 3 and an elastic body 4 that is integrated with an intermediate ring 5 embedded therein. The inner cylinder 2 has a large diameter part 6 formed at an intermediate part and having slant surfaces 7 at both ends in the axial direction. The intermediate ring 5 has an approximately semi arc shape in a section diagram perpendicular to the axial direction, and forming an inward projection 10 at one end side of a body part 8 parallel to the axial direction. A pair of the intermediate rings are arranged at both ends of the inner ring 2, facing each other in opposite directions, and respective slant surfaces 11 are arranged opposite to the slant surfaces 7 at the both sides of the large diameter part 6. If the outer cylinder 3 tries to move to either side in the axial direction by a lateral force F, spring of the elastic body 4 is increased by the intermediate ring 5 and a large reaction force is generated by a gap filling part 12 which is compressed between the slant surfaces 7 and 11, thereby generating a large displacement in the direction perpendicular to the axial direction.
