Claim:
1. A slider assembly comprising: a slider which comprises upper and lower plates which are provided with teeth guides and a pillar which connects the upper plate and the lower plate, the slider moving forward along teeth arranged at regular intervals on sides of first and second tapes, respectively, to engage the teeth with each other and moving backward to disengage the teeth from each other; a locking unit which is disposed at the first tape and limits the backward movement of the slider; a bottom unit which is disposed at the second tape, elastically coupled to the locking unit by a force that presses the bottom unit and the locking unit in an up and down manner in the thickness direction of the tape, and separated from the locking unit by a force that moves the slider backward; wherein one of the locking unit and the bottom unit comprises a coupling protrusion which is formed to protrude from an opposing surface and the other comprises a protrusion receiving portion to which the coupling protrusion is elastically inserted and coupled by a force that presses the bottom unit and the locking unit in an up and down manner; and wherein the protrusion receiving portion comprises: a through hole into which the coupling protrusion is inserted; an elastic body; and a shutter which is coupled to the elastic body, moves in a direction that opens the through hole during the elastic deformation of the elastic body such that the coupling protrusion can be inserted into and separated from the through hole, and moves in a direction that at least partially closes the through hole during the elastic restoration of the elastic body such that the coupling protrusion is confined in the through hole.
