回転可能に支持されるねじ状の第１の部材と、該第１の部材のねじ山に噛み合い、該第１の部材の回転により該第１の部材の軸方向に移動するねじ状の第２の部材とによって構成される移動装置を備え、前記第２の部材の移動に連動して、光学系を光軸方向に移動させる光学機器において、
前記第１の部材の軸方向断面に現れる前記ねじ山の山形状は、前記ねじ山の根元側にある第１の斜面、前記ねじ山の先端側にある第２の斜面、の２つの異なる頂角を有する斜面からなり、前記第１の斜面の頂角は前記第２の斜面の頂角より小さく、
前記第２の部材の軸方向移動の限界を定めるために設けられるストッパ手段に、前記第２の部材を前記第１の部材の外径方向に移動させる案内部を設けたことを特徴とする光学機器。 A screw-shaped first member that is rotatably supported, and a screw-shaped second member that meshes with the thread of the first member and moves in the axial direction of the first member by the rotation of the first member. In an optical device that includes a moving device configured to move the optical system in the optical axis direction in conjunction with the movement of the second member ,
The thread shape appearing in the axial section of the first member has two different apex angles: a first slope on the root side of the thread and a second slope on the tip side of the thread. The apex angle of the first bevel is smaller than the apex angle of the second bevel,
An optical device characterized in that a guide portion for moving the second member in the outer diameter direction of the first member is provided in a stopper means provided to determine the limit of the axial movement of the second member. Equipment .
