Patent number: 11559116Abstract: A slider includes a slider body part that includes an upper wing plate and a lower wing plate, a stop tab body, a tab elastic member that biases the stop tab body, a base part integrally formed with the upper wing plate, and an operation cover part rotatably attached to the base part. The operation cover part includes a pressing projecting part that projects from an inner surface of a top plate part, and the pressing projecting part has a configuration in which by rotating the operation cover part, a locked state and an unlocked state can be switched therebetween. Accordingly, since a stop mechanism by the rotation of the operation cover part can be provided in the slider with a relatively simple configuration, the manufacturing cost can be reduced and the productivity can be improved.Type: GrantFiled: December 20, 2018Date of Patent: January 24, 2023Assignee: YKK CorporationInventors: Yohei Miyazaki, Koji Yamagishi, Yoshikazu Hamada
