<p>A covering device (100) of an opening of a building includes two parallel rails (10), a shading member (20), a main member (32), and two adjusting units (36). Each rail (10) has a first side (10a) and a second side (10b). The main member (32) is between the rails 5 (10) and is connected to an end of the shading member (20). The main member (32) has two coupling members (34) to engage the rails (10) at the first sides (10a) thereof. The adjusting unit (36) has a stop member (361) to be moved between a first position and a second position. The stop member (361) touches the second side (10b) of the rail (10) while the stop member (361) is moved to the first position, and is off the second side (10b) 10 of the rail (10) while the stop member (361) is moved to the second position. 10a 364a 364 365</p> |
