Abstract:
Provided is a connection member for connecting a first member and a second member, wherein a line that links a first point, which is located on the central axis passing through a first location on the first member side and a second location on the second member side, and a second point, which is located at a location separated from the central axis, is integrally formed as a whole and has at least one spiral section having a shape that is thickened at a spiral surface and is formed by a spiral-shaped trajectory which is rotated about the central axis so as to be centered on the first point while the first point moves in one direction along the central axis. Through this, it is possible to reduce the number of components and to simplify assembly steps as compared to a ball joint or universal joint.
