PURPOSE: To get a guard lever, whose substantial length increases in operation and which is folded in writing and gets in compact condition by constituting it of the three parties of a main body member, which has a hook part and a pressing part, an arm member, which transmits torque, and a stopper member, with which the arm member can rotate between the extensive position and the retreat position.
CONSTITUTION: This comprises a main body member 1, an arm member 10, and a stopper member 20, and in the condition that the mounting part of the arm member 10 is set freely inside the slit of the main body member 1, the arm member 10 is born to the main body member 11 by the pin through pin holes 5 and 14. The card lever being assembled this way is attached, being born by the pin 7 through the pin hole 6, to corner of the front end of the printed board. And the arm member 10 rotates between the curvature position A, where it is folded to the main body member 1, and the extensive position B, where it has rotated in the direction of an arrow. Hereby, the arm member 10 can be shortened, being folded in the curvature position in nonoperation, and can be extended only in operation and can be drawn out effectively.
