The device comprises an ear portion protruding from the movably connected side of the lid, a cover member cooperating with the ear portion to define a hollow space therebetween, a shaft member longitudinally extending between the ear portion and cover member in the hollow space, and a torsion spring fitted to and surrounding the shaft. The torsion spring has a helical portion with first and second endmost turns. Each endmost turn has an arm extending from the shaft including a straight portion and a bending portion. The bending portion of each endmost turn each has a bent portion and a tip opposite the bent portion. When the lid moves towards the casing, the bending portions are compressed in opposing directions by the ear portion and cover member, thereby controlling the lid's motion with respect to the casing.
