PROBLEM TO BE SOLVED: To prevent the generation of noise.SOLUTION: A motor shaft 78 is inserted in a center hole 83 of a worm 80 and fitted in a direction around an axis. A tip end portion 80a of the worm 80 is stored in a bearing recessed portion 93. A worm wheel 50 is engaged with the worm 80. Rotations of the worm wheel 50 are transmitted to a visually confirming device rotating portion 15 to move the visually confirming device rotating portion 15 between a developing position and a retracting position. Between the motor shaft 78 and the center hole 83 of the worm 80, a clearance g1 in a diametrical direction and play r in a rotating direction are provided. Between the tip end portion 80a of the worm 80 and the bearing recessed portion 93, a clearance g3 in the diametrical direction is provided. The clearance g3 is provided to have size with which an outer peripheral surface 80b of the tip end portion 80a of the worm 80 and an inner peripheral surface 93a of the bearing recessed portion 93 are not contacted with each other when the work 80 rotates.SELECTED DRAWING: Figure 1

    【課題】異音の発生を防止する。【解決手段】ウォーム80の中心穴83にはモータシャフト78が差し込まれて軸周り方向に嵌合する。ウォーム80の先端部80aは軸受凹部93に収容される。ウォーム80にはウォームホイール50が噛み合う。ウォームホイール50の回転は視認装置回転部15に伝達されて視認装置回転部15を展開位置と格納位置に移動させる。モータシャフト78とウォーム80の中心穴83との間には径方向の隙間g1および回転方向の遊びrが構成されている。ウォーム80の先端部80aと軸受凹部93との間には径方向の隙間g3が構成されている。隙間g3は、ウォーム80が回転しているときにウォーム80の先端部80aの外周面80bと軸受凹部93の内周面93aとが接触しない大きさに構成されている。【選択図】図1
