40 While the amount of elastic deformation is small, the rotational force from the handle is transmitted to the axle linkage via the yoke outer cylinder 1, the outer cylinder 12, the rubber stopper 16, the fork Ml (21, the inner cylinder 13, and the shaft 2). At this time, the rotational force of the yoke outer cylinder part 1 in the direction of the arrow X is transmitted to the outer cylinder 12, and as a result, the part of the rubber bushing part 14 on the outer cylinder 12 side between the insertion holes 15 shifts in the direction of the arrow X, and this deviation is transmitted to the fork portion 21 disposed in front, and the rotational force of the rubber stopper 16 in the direction of the arrow X is transmitted to the side surface of the concave groove portion 20 of the fork portion 21. The rotational force transmitted to the shaft 2 is transmitted to the shaft 2 by the engagement between the engagement groove 22 and the protrusion 23.Moreover, as the rubber bushing portion 14 shifts in the direction of the arrow X, the inner cylinder 13 moves in the same direction. The rotational force of the inner cylinder 13 is also transmitted to the shaft 2. As a result, the rotational force of the yoke outer cylinder 10 is quickly and precisely transmitted to the shaft 2, improving rotation response performance. In addition, if the elastic deformation layer in the circumferential direction of the rubber shoe 71 part 140 becomes large, the rotational force from the handle will be 1/-)
