Abstract
A semi-automatic sunshade device includes a housing receiving a winding shaft to hold a shading cloth. An upstanding guide rod for operating the shading cloth is inserted into a guide rod case disposed beneath the housing. A buffer support is disposed between the housing and the guide rod case to hold a hollow moving body. The guide rod extends through the hollow moving body and is clamped movably by buffer members that are disposed inside the moving body in rolling contact with the guide rod. The buffer members hinder movements of the guide rod and are able to prevent impact forces when the shading cloth is stretched or un-stretched.
