PROBLEM TO BE SOLVED: To provide a case lock device which improves crime prevention and design. SOLUTION: A control lever handle 20 of the case lock device is provided with an operating handle 22 which is formed in such a shape as to be extended out upward from a leading end of a rotating shaft 21, and a cylinder cover 23. When the operating handle 22 is in a standby position, the operating handle 22 is arrange in a position to face a cylinder lock 15, and a notched portion 23a is provided at the leading end of the cylinder cover 23 in a mutually opposed state in such a manner as to be fitted into the cylinder lock 15. Thus, the operating handle 22 and the cylinder cover 23 make the cylinder lock 15 hardly visible by screening the cylinder lock 15. Consequently, since an inner cylinder with a keyhole of the cylinder lock 15 can be hardly identified, the crime prevention can be enhanced. Additionally, the design of the door can be improved by designing the control lever handle for screening the inner cylinder with the keyhole. COPYRIGHT: (C)2009,JPO&INPIT
