Abstract

See full text

A spring drive device is for use with a sunshade assembly which includes a coupling shaft coaxial to and rotatable with a winding shaft and formed with a guided path. The spring drive device includes a spring member disposed in and connected to a shell unit. A connecting shaft is formed with a guideway which has an initial region engaged with the spring member, such that when the connecting shaft is moved along a coupling route, the guideway is kept in slidable engagement with the spring member until a relay region of the guideway reaches the spring member. The connecting shaft is engageable with the coupling shaft to align the guided path with the guideway such that when the movement of the connecting shaft is continued after the relay region reaches the spring member, the guided path is brought to take over the slidable engagement with the spring member.
