Abstract
A slider provided with a stopping mechanism has a press molded slider body and a stopping pawl body. The stopping pawl body has a main body, a pawl portion extending from one end side of the main body, an extending portion extending from the other end side of the main body, and a projecting portion projecting from a tip portion of the extending portion, and the extending portion has a rotation support part of the stopping pawl body. A contact surface with which the rotation support part of the upper blade is in contact is formed into a flat surface. According to this constitution, a defect and failure of the stopping mechanism hardly occur in the slider, so that the stopping mechanism can be stably operated for a long period of time.
