| description | To provide a lens barrel having a switching mechanism with aperture click feeling, which is space saving despite simple configuration, has no adverse effect on the feeling when switched and is excellent in appearance quality.SOLUTION: The lens barrel includes: a changeover switch 40; a switch base 41 fixed to the changeover switch; a rotatable cylindrical ring member; and a hold-down spring 45 fixed to a fixed cylinder. The ring member includes: an uneven part along the circumferential direction of an inner peripheral part; and a flat part adjacent to the uneven part. The switch base has a through-hole. An urging member whose one end is in contact with a spherical member 46 and other end is in contact with the hold-down spring is inserted into the through-hole.SELECTED DRAWING: Figure 3
【課題】簡易な構成ながら径方向に省スペースであり、切り替え時の感触に悪影響がなく、外観の品位に優れた絞りクリック感の切り替え機構を有するレンズ鏡筒を提供する。【解決手段】切り替えスイッチ４０と、前記切り替えスイッチと固定されたスイッチベース４１と、回転可能な円筒状のリング部材と、固定筒に固定された抑えバネ４５と、を有し、前記リング部材は内周部の周方向に沿って凹凸部と、前記凹凸部と隣接する平坦部とを有し、前記スイッチベースは貫通穴を有し、前記貫通穴には一端が球状部材４６と接し、他方の一端が前記抑えバネと接する付勢部材が挿入されていることを特徴とした。【選択図】図３ |
