PURPOSE: A roller-type skylight opening and closing apparatus is provided to easily adjust temperature and to ventilate the air in the green hose to open and close a plurality of skylights in one direction or either direction with a chain, a towing rod, and a towing roller. CONSTITUTION: A drive sprocket(11) and an orientation sprocket(12) are installed on either end of a greenhouse structure. A skylight(5) is opened and closed by reciprocating a towing roller vehicle(2) through a chain(13) and a towing rod(14). An opening and closing motor makes rotating force in a longitudinal direction of the greenhouse. A driving shaft(15) transfers the rotating force of the opening and closing motor to the sprocket. The chain converts rotation movement to reciprocating linear motion. A chain(13a) and a towing rod(14a) offer force from the orientation sprocket to the drive sprocket.
