There is provided a slide fastener slider. A front mounting portion and a rear mounting portion are respectively provided with receiving grooves for receiving a lock member. The receiving grooves have right and left side walls. Protrusions are respectively provided on upper end edges of the side walls of the front mounting portion. When the upper end portions of the side walls of the front mounting portion are inclined in a direction of approaching each other, the protrusions approach each other, and the protrusions cover the lock member more largely relative to portions of the side walls other than the protrusions.

There is provided a slider for a slide fastener. The slider includes a body, a pull tab, a shaft member, and a coil spring. The pull tab has a base portion, a gripper and a claw portion protruding from the base portion. The shaft member is configured to rotatably support the pull tab relative to the body. The coil spring is attached around the shaft member to urge the gripper to be laid down toward the body. A claw guide portion allows a tip end of the claw portion to protrude into the guide groove. A restricting portion of the body restricts rotation of the pull tab when the pull tab is raised by a predetermined angle from the body. A restricted portion of the pull tab comes in contact with the restricting portion when the pull tab is raised by the predetermined angle from the body.

A method includes: agitating base members that has been immersed in an electrolytic solution inside of an electroplating tank so as to flow in a circumference direction along an inner wall of the electroplating tank; and electroplating the base members flowing along the circumference direction in the electrolytic solution inside of the electroplating tank. The flow of the base members along the circumference direction is caused by a flow of magnetic media along the circumference direction in the electrolytic solution inside of the electroplating tank or is caused by rotation of an agitation unit provided at a bottom side of the electroplating tank. At least one of the base members touches a bottom cathode, and a base member positioned upward relative to the base member touching the bottom cathode is electrically connected to the bottom cathode via at least the base member touching the bottom cathode.

A cap structure includes a cap body and an elastic piece. The cap body has at least two first inner concave grooves corresponding to each other, at least two first retaining blocks corresponding to each other and respectively extended outwardly from the at least two first inner concave grooves, and at least two first through holes corresponding to each other and respectively adjacent to the at least two first retaining blocks. The at least two first inner concave grooves are disposed on the inner surface of the cap body, and the at least two first through holes pass through the cap body to form two breach holes between the inner and the outer surfaces of the cap body. The elastic piece is disposed on the inner surface of the cap body, and the at least two first retaining blocks contact the elastic piece for retaining the elastic piece.

The present device provides a slide assembly for a zipper, and a method for manufacturing a zipper slide assembly. The slider assembly is formed in a single die cast operation to include the slider and the pull member being formed simultaneously. Whereby the bridge and pull loop are formed with their full geometric shape and without converging flat surfaces caused by tooling limitations found in the prior art.

There is provided a slider cover for a slide fastener. An upper member and a lower member are spaced apart from each other in an upward and downward direction and arranged in parallel to each other. A connecting post connects the upper member with the lower member. The upper member includes a receiving portion configured to receive at least a part of an upper blade of a slider.
