ABSTRACT:
A window up-and-down-winding-type shielding apparatus for a conveyance includes: a pair of guide rails that are parallel to each other and that extend in an up-and-down direction; a moving member that is connected to a lower end of a shielding member and that can be moved in the up-and-down direction along the guide rails; a winding mechanism that has a rotation section for retractably winding the shielding member; a biasing force application device that applies a biasing force to the rotation section of the winding mechanism in a direction along which the shielding member is wound; a motion conversion mechanism that converts the movement of the moving member in up-and-down direction along the guide rails to a rotational motion; and an axis member that is coordinated with the motion conversion mechanism to have a rotational motion in accordance with the up-and-down movement of the moving member. The axis member is connected to a mechanism for switching a direction along which the rotative force is transmitted.
