<P>PROBLEM TO BE SOLVED: To provide a skylight window opening and closing device which can perform ventilation and smoke exhaustion without being so influenced by wind direction, can reliably hold a skylight window body, and can stably and smoothly separate the skylight window body from a skylight window frame body. <P>SOLUTION: This skylight window opening and closing device 1 includes: the skylight window frame body 5 disposed so as to surround a skylight window opening 4; the skylight window body 6 disposed on the skylight window frame body 5 in a freely approaching/separating manner in a V-direction orthogonal to the skylight window opening 4 so as to open and close the skylight window opening 4; an approaching/separating means 7 allowing the skylight window body 6 to approach and separate from the skylight window frame body 5 in the V-direction; an operation means 8 for operating the approaching/separating means 7 so as to allow the skylight window body 6 to approach and separate from the skylight frame body 5 in the V-direction by the approaching/separating means 7; and a guide coupling means 9 coupled to the skylight window frame body 5 and the skylight window body 6 so as to guide the skylight window body 6 for approaching and separating from the skylight window frame body 5 in the V-direction by the approaching/separating means 7. <P>COPYRIGHT: (C)2011,JPO&INPIT |
