るスイングギヤ装置。a drive gear driven by a motor; an intermediate gear meshed with the drive gear; a pair of reel base gears with which the intermediate gear is selectively meshed; and a rocking lever configured to be able to swing freely around the same shaft center as the shaft center, and in the FWD mode, the intermediate gear is held at an intermediate position between the two reel base gears, and the rotation direction of the drive gear is In the swing gear switching device, the swing gear switching device is configured to switch between the FF mode and the REW mode by swinging the swing lever and selectively meshing the intermediate gear with both the reel base gears. , the intermediate gear is attached to a support shaft provided on the swing lever so as to be rotatable around the shaft center and slidable in the axial direction of the support shaft, and the intermediate gear is attached to one side in the axial direction. A spring is provided that is slidably energized to constantly mesh with the drive gear, and in conjunction with switching to the FWD mode, the intermediate gear is slid in the other direction in the axial direction against the spring, so that the drive gear is engaged with the drive gear at all times. and release the meshing state with F.
A swing gear device comprising a switching mechanism that causes the intermediate gear to slide in one axial direction by the spring and mesh with the drive gear in conjunction with switching to F mode or REW mode.
