The subject innovation relates to a clamp coupled to the conveyor frame. The subject innovation will be provided at one side of the holding portion body so as to support the mounting object on the conveyor, the clamp being provided with a coupling to be coupled to the frame of the other conveyor side of the body portion, the one side of the coupling portion body the support surface is formed to be stepped to be in contact with the frame is formed, the support surface has a detent projection is formed by the end of the frame so that it rests, the back surface of the support surface in surface contact with the frame to be mounted to the end teokjin part of the body through a support block for the support blocks have to be in contact with and bonded to the support surface provides a support surface and supporting the clamp to be coupled to the conveyor frame, characterized in that configured to include a fastening member which allows to narrow the distance between the block do. Thus, the subject innovation will to clamp the eliminated product is generated real number of working, as well as due to a mistake by allowing the operator whether doeeotneun stationary on a frame of the conveyor can be recognized reliably defect, of the conveyor frame even if the width becomes large, which would have the effect of increasing compatibility with the width of the frame, it is possible to combine in response.
