Input device

An input device comprising:

• a rotating member that rotates about a predetermined rotation axis;
• and
• a mover that includes a protrusion and moves in a direction different from a rotation direction of the rotating member along with rotation of the rotating member, the protrusion protruding toward an inner peripheral surface of the rotating member, wherein
• the rotating member includes a first projection and a second projection that project from the inner peripheral surface toward the mover,
• the protrusion of the mover is inclined with respect to the predetermined rotation axis and disposed between the first projection and the second projection,
• the first projection and the second projection each include a spherical portion that contacts the protrusion, and
• the first projection includes:
• a first column member that projects from the inner peripheral surface of the rotating member toward the mover;
• and
• a first sphere member at a distal end of the first column member, the first sphere member having a diameter longer than a diameter of the first column member, and
• the second projection includes:
• a second column member that projects from the inner peripheral surface of the rotating member toward the mover;
• and
• a second sphere member at a distal end of the second column member, the second sphere member having a diameter longer than a diameter of the second column member.

• the protrusion of the mover is inclined with respect to the predetermined rotation axis and disposed between the first projection and the second projection, and
• the protrusion tapers toward both ends of the protrusion in a direction inclined with respect to the predetermined rotation axis, as viewed from a protruding direction of the protrusion.
