Slide fastener slider

A slide fastener slider, comprising:

• a slider body in which an element passage allowing linear elements to pass therethrough is formed between an upper plate and a lower plate by connecting the upper plate and the lower plate with a connecting post;
• a pair of flanges which are erected extending from a rear mouth side toward a shoulder mouth side of the slider body along both right and left sides of the lower plate;
• and
• pressing faces which are formed on inner side faces of the flanges along a longitudinal direction of the flanges, for guiding the linear elements passing through the element passage while pressing inverted portions of the linear elements, wherein
• the slide fastener slider further comprises:
• projecting portions which are formed so as to extend in a direction to the shoulder mouth side from shoulder mouth side end portions of the flanges, in which
• the projecting portions comprise stepped portions having a smaller height than top faces of the flanges;
• and
• downward slopes formed from the stepped portions to a top face of the lower plate, the downward slopes being formed in a continuous shape from the inner side faces of the flanges to outer side edges of the lower plate on the shoulder mouth side while being continuous to the pressing faces.
