Abstract:
A cord reel configured in such a manner that the position of a cord reel body can be easily adjusted when the cord reel body is located at an intermediate portion of cords. A cord reel is provided with a first bobbin (4) and a second bobbin (5) on which respective cords (2) are wound, bobbin impelling means (6) for always impelling both the bobbins (4, 5) in the take-up direction, and a bobbin interlock means (7) for interlocking both the bobbins (4, 5) together, the bobbin interlock means (7) being configured in such a manner that, when both the cords (2) are not being operated in the pay-out direction, the bobbin interlock means (7) restricts rotation of both the bobbins (4, 5) in the take-up direction, that, when the cords (2) are operated in the pay-out direction by an operating force not greater than a preset value, the bobbin interlock means (7) allows one of the bobbins to rotate in the pay-out direction and allows the other bobbin to rotate in the take-up direction in association with the rotation of said bobbin, and that, when a cord (2) is operated in the pay-out direction by an operating force greater than the preset value, the bobbin interlock means (7) releases the interlock between both the bobbins (4, 5) to cause only the operated bobbin to rotate in the payout direction.
