A dial unit having a high operation performance is provided. The dial unit includes a dial member 28 including a shaft 54 and being rotatable around the shaft 54, a detector 27 which detects a rotation amount of the dial member 28, a rotator engaged with the dial member 28 and rotatable together with the dial member 28, a first rotation transmission member interposed between the dial member 28 and the rotator and configured to keep the dial member 28 and the rotator separated from each other before the rotation angle of the dial member 28 reaches a first predetermined angle and to transmit rotation of the dial member 28 to the rotator when the rotation angle of the dial member 28 exceeds the first predetermined angle, and an elastic member which is shaped as a coil-shaped portion and contains the rotator inside the coil-shaped portion and which is configured to apply to the rotator a torque in an opposite direction to a rotational direction of the rotator when the rotator rotates.
