Abstract
From the “face” side of the base (12) of the male part (4), an engagement protrusion (18) extends directly upwards in the direction of the engagement socket (18). On the surface of the engagement socket (14) side of the base (12), a slanting surface (12a) parallel with the protrusion-forming slanting surface (18b) is formed. From the “face” side of the base (20) of the male part (8), an engagement protrusion (23) extends diagonally downwards in the direction of the engagement socket (21). On both sides of the step (23c), a wall (23e) is provided. On the “face” side of the engagement socket (21) of the base (20), a slanting surface (20a) parallel with the protrusion-forming slanting surface (23b) is formed. The snap fastener has directionality in respect not only of disengagement but also of engagement.
