Abstract
A photographic film cassette comprises a locking member pivotally movable into engagement with a spool to inhibit rotation of the spool. The locking member is moved by a light-shielding door member through a cam. A cam follower surface of the locking member is brought into contact with the cam in the closed position of the light-shielding door member, such that force biasing the light-shielding door member toward the closed position is applied from the locking member to the light-shielding door member in the closed position. The locking member is provided with a hook for engagement with a recessed portion formed in an inner wall of a cassette shell. The hook is engaged with the recessed portion when the locking member is placed in an initial assembled position. Thereafter, the locking member is rotated about the hook from the initial assembled position into a final assembled position where a smaller clearance is provided between the hook and the recessed portion compared with the initial assemble position.
