In an optical head device in which a lens holder ( 3 ) for mounting an objective lens ( 2 ) therein is formed integral with a housing ( 1 ) via a connecting part ( 5 ), a coil holder ( 6 ) having driving coils wound thereon is mounted, a movable part of an actuator is assembled by combining the lens holder ( 3 ) with the coil holder ( 6 ), an elastic support member ( 11 ) elastically supporting the movable part of the actuator on the housing ( 1 ) is strung to a support member ( 12 ) formed integral with the housing ( 1 ) and also strung to mounting parts ( 3 a, 3 b) formed integral with the lens holder ( 3 ), and, as the movable part of the actuator is supported on the housing ( 1 ) by the elastic support member ( 11 ), the lens holder ( 3 ) is detached from the housing ( 1 ) by removing a connecting part ( 5 ).
