Operation sensation imparting input device

An operation sensation imparting input device comprising:

• a rotatable operating knob;
• a first rotating body that is driven by the operating knob and is rotated coaxially with the operating knob;
• a second rotating body that is driven by the first rotating body, is rotatable coaxially with first rotating body, and transmits a braking force to the first rotating body;
• a friction plate that is rotated integrally with the second rotating body;
• an electromagnetic brake that applies a braking force by magnetically attracting the friction plate when current is applied to the electromagnetic brake;
• and
• a detection mechanism that detects the rotational position of the operating knob,
• wherein cam surfaces are formed on one of the first and second rotating bodies, and driving bodies elastically coming into press contact with the cam surfaces are held by the other thereof,
• while the rotation of the friction plate is prevented by the magnetic attraction of the electromagnetic brake, the first rotating body is rotatable relative to the second rotating body until the first rotating body comes into contact with the second rotating body so that the position of the first rotating body is restricted, and
• the driving bodies slide on the cam surfaces while increasing contact pressure with the relative rotation.
