<P>PROBLEM TO BE SOLVED: To inexpensively provide an epoch-making hanging hook easily holdable even at a predetermined angle, while smoothly performing the rotary operation of a suspending bolt suspending body, only by roughly and firmly fastening the fastening condition of a fastening bolt, in the hanging hook constituted of a fixing body fixed to an installation object plate and the suspending bolt suspending body for threadably attaching a suspending bolt, and rotatably journaling the suspending bolt suspending body. <P>SOLUTION: This hanging hook is provided with a projecting friction part for reducing rotational frictional resistance in rotary operation, under a pressure contact state of a plane and a point from a conventional pressure contact state of a plane and a plane, in a sandwiching interface of bringing the fixing body and the suspending bolt suspending body into pressure contact with each other. <P>COPYRIGHT: (C)2011,JPO&INPIT |
