The present invention relates to a toggle clamp, and more specifically, to a toggle clamp which reduces friction during operation and prevents iron powder due to abrasion of metal. According to the present invention, the toggle clamp comprises: a rod unit (110); a handle unit (150); and a link unit (130). The link unit (130) has a plurality of hinge coupling portions (133) in a rotational coupling portion. At least a portion among the rod unit (110) and the hinge coupling portions (133) does not generate the iron powder caused by abrasion of metal during operation and has a special material of which friction coefficient is lower than the friction coefficient of steel.
