Abstract
A coupling apparatus is provided with a first coupling member, a second coupling member and a damper member. The damper member is arranged between the first coupling member and the second coupling member. At least one of the first coupling member and the second coupling member has a tubular circumferential wall surrounding the outer circumference of the damper member. Accordingly, it is easy to control the diameter of an accommodating hole accommodating the coupling apparatus.
