Provided is a dial unit with improved operability. The dial unit includes a dial member 28 having a shaft 54 and being rotatable about a shaft 54, a detecting portion 27 for detecting the amount of rotation of the dial member 28, and a dial member 28 engaged with the dial member 28 A dial member interposed between the dial member and the rotor and separating the dial member and the rotor from each other until the rotation angle of the dial member reaches a first predetermined angle, A first rotation transmitting member that transmits the rotation of the dial member to the rotor when the rotation angle of the member exceeds the first predetermined angle And an elastic member capable of applying a rotational force to the rotor in a direction opposite to the rotational direction of the rotor when the rotor rotates.操作性を向上したダイヤルユニットを提供する。 ダイヤルユニットは、軸54を有するとともに軸54を中心に回転可能なダイヤル部材28と、ダイヤル部材28の回転量を検出する検出部27と、ダイヤル部材28と係合してダイヤル部材28と一緒に回転可能な回転子と、ダイヤル部材28と前記回転子との間に介在され、ダイヤル部材28の回転角度が第1の所定角度に至るまではダイヤル部材28と前記回転子とを分離し、ダイヤル部材28の回転角度が前記第1の所定角度を超えた際にダイヤル部材28の回転を前記回転子に伝達する第1回転伝達部材と、コイル形状をなして当該コイル形状の内側に前記回転子を位置させ、前記回転子が回転した際に前記回転子に対して前記回転子の回転方向とは逆方向に回転力を付与可能な弾性部材と、を備える。
