Abstract: An elastic abutting device disposed on one link of a two link mechanism includes a base member, a bearing member, a latch member, and an elastic member. The base member has an accommodating groove. The bearing member is disposed in the accommodating groove, wherein the bearing member has a first propping portion, a second propping portion, and a through hole. The latch member defines a central axis, and the latch member has an abutting portion which is partly exposed out of the through hole and a retaining portion which is disposed correspondingly to the abutting portion. The elastic member is disposed between the first propping portion and the second propping portion, wherein two opposite terminal ends of the elastic member respectively have a first side end portion and a second side end portion disposed correspondingly to the first side end portion.

Abstract: A multi-stage sunshade device includes two fixed frames, two first operable frames, two second operable frames, multiple first operable blades, a first lined module, a second linked module, and multiple second operable blades. The two fixed frames, two first operable frames, and two second operable frames cooperatively define a main window plane, a first window plane, and a second window plane. The first operable blades and the second operable blades selectively cover the first and the second window planes via the two first and two second linked modules. Two first operable frames and two second operable frames each having two ends, one end of each is coupled to one another, while the other end of each is coupled to the guiding rails on the two fixed frames, so that the two first and two second operable frames can be proximate to or distal from one another.
