Abstract: A connection structure includes first and second members disposed facing each other and an elastically deformable damper, where the first and second members are connected via the damper. The damper is made of an elastically deformable material, and includes a cylindrical portion, a flange, a first vibration absorber, and a second vibration absorber. The first member includes a convex support portion and a first contact portion in contact with a first contact surface. The second member includes a concave support portion and a second contact portion in contact with a second contact surface opposite the first contact surface. Each of ribs protrudes radially outward of the cylindrical portion and extends in an axial direction. The ribs are provided alternately on an inner periphery and outer periphery of the cylindrical portion such that positions of the ribs differ from one another in a circumferential direction of the cylindrical portion.
