Abstract
A coupling device comprises a drive portion formed on a drive shaft and having a drive wall surface extending in the direction of a rotation axis; a driven portion formed on a driven shaft and having a driven wall surface extending in the direction of the rotation axis; a convex curved portion formed on one of the drive wall surface and the driven wall surface and extending along the rotation axis at a position spaced from the rotation axis as viewed in the direction of the rotation axis; and a concave curved portion having a smaller curvature than that of the convex curved portion and formed on the other of the drive wall surface and the driven wall surface to contact the convex curved portion and extending along the rotation axis at a position spaced from the rotation axis as viewed in the direction of the rotation axis.
