A sunshade apparatus for a vehicle includes a shading sheet, which opens and closes a light transmitting portion of a vehicle roof, a pair of holding members, which retain the shading sheet, a winding member, which winds the shading sheet and the holding members. The shading sheet is retained at edge portions of the shading sheet, which extend in the shading sheet opening-closing directions by the holding members. The holding members are retained to the winding member in a manner so that winding in at one end in turn winds off the other end and movement direction thereof is reversed at a direction change member positioned at a distance from the winding member in the shading sheet opening-closing directions and the winding member includes a biasing member, which balances tensional force acting in the shading sheet opening-closing directions at one end and the other end of each holding member.
