Abstract
A covering device of an opening of a building includes two parallel rails, a shading member, a main member, and two adjusting units. Each rail has a first side and a second side. The main member is between the rails and is connected to an end of the shading member. The main member has two coupling members to engage the rails at the first sides thereof. The adjusting unit has a stop member to be moved between a first position and a second position. The stop member touches the second side of the rail while the stop member is moved to the first position, and is off the second side of the rail while the stop member is moved to the second position.
