A snap-fastener having a male member and a female member, respectively having a cap with a rivet shaft piercing through a sheet member and a male part or a female part. The rivet shaft is inserted into an insertion hole so that an inner edge of a hole of the sheet member is sandwiched to have a seal portion. The male part has an engaging projection projecting outwardly at an end of a cylindrical engaging portion. The female part has a resilient engaging member urged axially inwardly and placed outwardly in diameter direction with respect to the engaging portion. The resilient engaging member has at least a locking projection projecting inwardly in diameter direction. The locking projection engages with the engaging projection to lock it so as to restrict its axial movement at the time of engagement between the male part and the female part. In order to disengage this locking, an exclusive device is used for moving the locking projection of the resilient engaging member outwardly in diameter direction.
