Abstract
A front section of a hook point member, relative to a rotating direction, of a rotating hook assembly is replaceable. The member can be replaced with a new one when a hook point is worn. Also, the replaceable member is made of a material of high hardness, such that burr-like edges will not be formed, thereby making it possible to obtain good sewing performance for a long period of time. The hook point and a claw may be formed integrally and can be replaced when the hook point and/or the claw is worn.
