摘要： Provided is a male snap button (10) including a metal male snap body (20), and a fixing member (30) for fixing the male snap body (20) to a fabric (1). The male snap body (20) includes: a male-side engagement part (21) in annular shape capable of being removably engaged with a female-side engagement part (60) of a female snap button (40); and multiple claws (27). The male-side engagement part (21) defines an opening (28) that exposes the fabric (1) inside in a radial direction thereof. A diameter (D1) of the opening (28) is greater than a length (W1) in the radial direction from an outside edge of the opening (28) in the radial direction to an outside edge of the male snap body (20) in the radial direction. The fixing member (30, 30a) includes claw accommodation parts (33) to receive the claws (27).

摘要： An upper structure of a female snap button includes a post holding member for holding a post of a male snap button, and a receiving member for receiving the post holding member. The receiving member includes a surrounding wall that extends in an up and down direction to surround the post holding member, a bottom portion that is coupled to a lower end of the surrounding wall and provided inward of the surrounding wall, and a peripheral portion that is coupled to an upper end of the surrounding wall and provided outward of the surrounding wall. An opening is defined by a rim between the upper end of the surrounding wall and the peripheral portion.

摘要： A button back which makes it possible to form the front surface of a button to be a circular shape; a shell cap hard to be rotated; and an umbrella part hard to be deformed. The button back is made of metal, including a cylindrical part and an umbrella part extending radially outward from one axial end of the cylindrical part. The umbrella part includes a first bending part which extends radially outward from the one axial end of the cylindrical part and then bends on the opposite side of the cylindrical part. An outer periphery, including a radially outer end, of the first bending part has a polygonal shape including at least three corners and sides which extend between two circumferentially adjacent corners. The umbrella part includes flat plates extending radially outward from the radially outer end, corresponding to the sides, of the first bending part.

摘要： A snap button includes a female snap body and a socket ring. The female snap body includes a bottom portion and a side wall rising from a peripheral edge of the bottom portion, the side wall provided with a holding portion for holding the socket ring. The socket ring includes a flange portion arranged radially outward and held by the holding portion and an engaging portion arranged radially inside the flange portion. The engaging portion protrudes downwardly toward the bottom portion side of the female snap body and below the flange portion, in the axial direction of the socket ring. An inner diameter of the socket ring may be gradually increased from an intermediate point in the axial direction of the engaging portion to one end and other end in the axial direction of the engaging portion. The engaging portion of the socket ring may be provided with a plurality of slits along the radial direction in the circumferential direction.

摘要： There is provided an end stop. A male member and a female member are configured to sandwich opposing side edge portions of a pair of fastener tapes from both sides thereof in an upward and downward direction. The male member includes a circular disk-shaped male base member and an inserting male portion. The female member includes a circular disk-shaped female base member and a receiving female portion. A facing surface of at least one of the male base portion and the female base portion is provided with a protrusion group. The protrusion group is configured so that a plurality of protrusions protruding to come at least in contact with each fastener tape are arranged to be spaced from each other at predetermined angles over the entire circumference of the facing surface along a circumferential direction thereof
