<P>PROBLEM TO BE SOLVED: To prevent return rotation of a cum mechanism in a filter apparatus. <P>SOLUTION: A rotation member 31 having a cum mechanism is disposed on the back surface of a filter unit 12, and a lever 50 is attached to the rotation member 31. The lever 50 is attached with a stopper 51 slidable in the longitudinal direction of the lever. The rotation member 31 presses the filter unit 12 forward through upward rotation made by the lever 50 so as to fix the filter unit 12 to the casing 11. The rotation of the lever 50 brings the stopper 51 into contact with the top surface 11C of the casing 11. After rotation of the lever 50, the stopper 51 is moved left so as to pass partially through the shaft portion 34B, leading to prevention of return rotation of the rotation member 31. <P>COPYRIGHT: (C)2013,JPO&INPIT |
