前記金属ブラシを、前記固定筒の外周に周方向に巻き付け固定されたパターン電極に摺動させ、前記金属ブラシと前記パターン電極との位置関係を電気信号として検出する構成を備えたレンズ位置検出装置において、
前記回転力伝達部材は、前記固定筒と対向する方向に向けられた突起部を有し、
前記突起部と前記固定筒との間隔が、前記回転力伝達部材を前記固定筒側に変形させた際、前記金属ブラシが前記固定筒に押しつけられて塑性変形を生じない間隔に設定されていることを特徴とするレンズ位置検出装置。 A fixed barrel that holds a holding barrel that holds the lens , a rotational force transmitting member that is disposed on the outer peripheral side of the fixed barrel and transmits rotational force to the holding barrel , and the position of the rotational force transmitting member can be adjusted. With mounted metal brush,
A lens position detection device comprising a configuration in which the metal brush is slid on a pattern electrode wound and fixed in the circumferential direction around the outer periphery of the fixed cylinder, and a positional relationship between the metal brush and the pattern electrode is detected as an electric signal. In
The rotational force transmission member has a protrusion directed in a direction facing the fixed cylinder,
An interval between the protrusion and the fixed cylinder is set to an interval at which the metal brush is pressed against the fixed cylinder and does not cause plastic deformation when the rotational force transmitting member is deformed to the fixed cylinder side. A lens position detection device characterized by the above.
前記突起部と前記固定筒との間隔が、前記回転力伝達部材を前記固定筒側に変形させた際、前記回転力伝達部材の突起部と前記突起受け部とが係合し、光軸回りの回転が規制されることを特徴とする請求項１に記載のレンズ位置検出装置。 The fixed cylinder has a protrusion receiving portion provided on an outer periphery of the fixed cylinder that engages with a protrusion of the rotational force transmitting member,
Distance between the fixed cylinder and the protrusion, when the rotational force transmitting member is deformed to said fixed barrel side, the protrusion of the torque transmitting member and the front Ki突 force receiving portion is engaged, the light The lens position detection device according to claim 1, wherein rotation about an axis is restricted.
