Abstract:
A camera filter unit ( 10 ) includes a front ring ( 4 ) for holding a polarization filter ( 2 ) and a rear ring ( 5 ) for rotatably holding the front ring ( 4 ). The front ring ( 4 ) includes a rear annular wall portion ( 18 ) extending in a radial direction (R), a rear annular plate portion ( 19 ) extending rearward from the inner peripheral end of the rear annular wall portion ( 18 ), and an annular projection portion ( 20 ) projecting for a short distance from the rear end of the rear annular plate portion ( 19 ) toward the outer peripheral side. The rear annular wall portion ( 18 ), the rear annular plate portion ( 19 ), and the annular projection portion ( 20 ) form an annular recess ( 21 ) on the outer peripheral surface of the front ring ( 4 ). The rear ring ( 5 ) includes an annular protrusion ( 45 ) protruding to the inner peripheral side. The annular protrusion ( 45 ) is inserted into the annular recess ( 21 ) of the front ring ( 4 ).

Claim (Index 16):
A camera filter frame comprising:\n a ring having an annular projection portion, which project toward an inner peripheral side; an inner ring, which is held in the inner peripheral side of the ring; wherein the inner ring has an annular frame for holding an optical element on the inner peripheral side, and a rear stopper, which projects from a rear end of the annular frame toward the inner peripheral side thereof and restricts a rearward movement of the optical element, wherein an inner peripheral surface of the annular frame which extends from a front end thereof to the rear stopper thereof functions as a holding surface, which holds the optical element coaxially, the front end of the annular frame is in contact with the annular projection portion of the ring, and the annular projection portion is abuttable with the optical element from a front side thereof.
