A rotary input device includes: a rotary operating unit which has an operating tubular portion formed from a first material and rotationally operated, and a gripper formed from a second material which has more elasticity than the operating tubular portion, the gripper covering an outer surface of a one-end side of the operating tubular portion; a casing which has the rotary operating unit disposed therein rotatably about an axis of the rotary operating unit, and which has a locking portion for restricting a rotational range of the rotary operating unit; and an input unit which transmits a predetermined signal with the rotation of the rotary operating unit. The operating tubular portion further includes, on the other-end side thereof, a portion to be locked that has a rotational range restricted to a predetermined rotational angle by the locking portion. The operating tubular portion is provided with an extension portion that is formed from the second material integrally with the gripper, and that extends toward the other end of the operating tubular portion from the gripper. The extension portion has an abutting portion that covers at least a portion of the portion to be locked and abuts against the locking portion.
