To make a fan easy to hold and to compactly house it by forming a key groove in the center of the lower part of the fan leaf of a single body, inserting a key piece provided at the upper part of a grip into this groove so as to connect the fan leaf and the grip to match a grip winding holding line to the edge of the fan leaf to connect fold/bend so as to fix the grip by role in by the lower part of the fan leaf.

The fan leaf 1 is provided by a single body by forming a fan- shape, the key groove 3 is formed by a vertical and straight notch in the center of the lower part and a folding line 5 equally divided in the state of a fan is formed. The grip 2 is divided into three rooms 8 by forming a picture winding folding line 5 being a radial mountain-folding line and a notch is formed in the shape of the nose of an eagle at the upper part of an inner room 9 to segment a key piece 4. By inserting the piece 4 to the groove 3, the grip 2 is connected to the leaf 1 in the state of hanging and the line 5 is folded in this connecting state to wind to the lower part of the leaf 1 in the order of a center room 14 and an external room 10. After winding the grip 2 to the lower part of the leaf 1, the inserting piece 13 of the room 10 is inserted to the fixed groove 11 of the room 9 to fix the wound state of the grip 2.
