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 21):
The camera filter frame according to  claim 19 , wherein the ring has a thick portion, which extends rearward with a constant thickness from a midway position of the annular projection portion in a radial direction,\n the internal thread is provided on a rear side of the thick portion, the thick portion of the ring has an annular rearward surface between the thick portion thereof and the internal thread thereof, the inner ring has a thin ring portion and a thick ring portion in this order toward a rear thereof from a front thereof, the external thread of the inner ring is formed on an outer peripheral surface of the thick ring portion thereof so that an outer peripheral surface of the thick ring portion is positioned so as to be closer to the outer peripheral side than an outer peripheral surface of the thin ring portion, the inner ring has an annular forward surface, which is directed to the front, and provided between the thin ring portion and the thick ring portion, and the annular forward surface of the inner ring and the annular rearward surface of the ring face each other with a gap, or are contact with each other.
