Disclosed is a device for turning rotatable rods for folding or unfolding wheels of a carrier, the device comprising: a pair of rotatable rods, each of which comprises one or more helical lines; a cross bar comprising helical line coupling portions coupled to one or more helical lines, and one or more elastic members, which provide restoring forces to the cross bar.
1. A device for turning rotatable rods for folding or unfolding wheels of a carrier, comprising: a pair of rotatable rods, each comprising one or more helical lines;a cross bar, which comprises one or more helical line coupling portions slidably coupled with the one or more helical lines on both sides and connects the pair of rotatable rods to each other;a frame or a body on which the pair of rotatable rods are rotatably installed; andone or more handle bars separated from the cross bar and installed on the frame or the body to be vertically slidable. 2....
