Patent attributes
It is an object of the present invention to provide a winding device that can correctly and separately rotate and drive two winding units by changing a rotation direction of a handle. The present invention is a winding device (10) including a first rotation shaft (11) that rotates and drives a first string winding unit (D1), a second rotation shaft (12) arranged coaxially with the first rotation shaft (11) to rotate and drive a second string winding unit (D2), a first gear (G1) coupled to the first rotation shaft (11), a second gear (G2) coupled to the second rotation shaft (12), a sliding gear member (40) arranged between the first and second gears (G1, G2) and including a third gear (G3) and a fourth gear (G4) respectively engaged with the first gear (G1) and the second gear (G2), a handle (50) including a gear accommodation portion (51) that accommodates the first to fourth gears (G1 to G4), an inclined groove (55) formed in an inner surface of the gear accommodation portion (51), and an engagement projection (45) that is formed on an outer surface of the sliding gear member (40), engages the inclined groove (55), and is slidable in the inclined groove (55).
