Description of the Related Art In general, in a female member made of a synthetic resin of this type, the inner diameter of the female fitting portion at the opening end side is made to protrude from an inner peripheral surface of the female member. Is smaller than the outer diameter of the tip side. When the protrusions of the male member are fitted and disengaged from each other, the protrusions are pressed radially outward by the protrusions. It is configured to be deformed to have a large diameter.

(Snap action) with the projections tends to be tight. Therefore, if there is a slight manufacturing error in the inner diameter of the open end side of the female fitting portion or the outer diameter of the distal end side of the protrusion of the male member, the fitting becomes impossible or the fitting is impossible. As a result, fitting and disengaging may become difficult.

た開口部を形成したことを特徴とている。The technical means adopted by the present invention to achieve the above object are as follows. That is, the synthetic resin female member for the snap fastener according to the present invention is inclined so as to become lower toward the outside, and then, in the center of the annular substrate that hangs down, is recessed on the back side and is formed on the inner peripheral surface on the upper end side. A female fitting portion is formed in which a raised portion for locking the projection of the male member is formed with a small gap in the circumferential direction, and at the center of the bottom wall of the female fitting portion, A through hole is formed for inserting a projection of a rivet member driven from one side of the flexible film body and caulking, and a groove formed between the back surface of the annular substrate and the female fitting portion is provided with the protrusion. A synthetic resin female member for a snap fastener having a plurality of ribs connecting the female fitting portion and the annular substrate at positions corresponding to the small gaps between the raised portions and the annular substrate. While forming a thinner portion than the annular substrate, One between the ribs to each other, and the feature that it has an opening which opens radially.

とを防止できるのである。According to the above construction, when the male member is snapped with the projection, the portion of the female fitting portion that resists the elastic deformation, that is, the raised portion of the conventional synthetic resin female member is formed. Since a radially open opening is formed in a portion corresponding to the cylindrical peripheral wall portion located below, the ridge is easily elastically deformed in the radial direction, and furthermore, the ridge is formed. By the fact that the connection portion between the and the annular substrate is formed thin, and the opening is formed below the raised portion, the raised portion is not only in the radial direction,
It is also possible to elastically deform in the vertical direction (axial direction). Therefore, even if there is some manufacturing error in the inner diameter at the open end of the female fitting portion or the outer diameter at the tip end of the projection of the male member, fitting becomes impossible or fitting and disengaging becomes difficult. It can be prevented from becoming dull.
