1. A continuous finishing apparatus for a slide fastener, the apparatus comprising:
a slider introduction portion for successively introducing a slider by intermittently running a slide fastener chain in which a meshed engaging element row and a space portion having no engaging element are disposed alternately in a longitudinal direction;
a positioning opening and closing member capable of thrusting into and departing from the space portion of the slide fastener chain, the positioning opening and closing member opening and closing the space portion;
a slider holding member which is disposed in a downstream of the slide fastener chain relative to the positioning opening and closing member and which advances to and retreats from the space portion opened by the positioning opening and closing member; and
a slider introduction member disposed in a downstream of the slide fastener chain relative to the slider holding member, the slider introduction member being capable of thrusting into and departing from the opened space portion; being reciprocated between a first position in the space portion and a second position in the downstream portion of the slide fastener chain; when it goes forward, supporting an engaging element disposed at a second end portion in the downstream portion of the slide fastener chain of the space portion and moving up to the second position while pulling the slide fastener chain so that the engaging element row disposed at a first end portion in an upstream of the slide fastener chain of the space portion is inserted into the slider held by the slider holding member.
