はかれる利点がある。 In other words, in order to switch between a mode in which the drive is performed only in one direction and a mode in which the drive is possible in a state where the forward and reverse rotations can be performed, a horizontal shaft that is incorporated and supported in the rotary case and a bevel gear that is rotatably supported on the horizontal shaft are incorporated and supported in the rotary case. Since this is intended to be done by replacing the connector and the forward/reverse switching device between the The desired purpose can be achieved with a structure that allows easy switching operations, which is of great practical advantage. In particular, the input/output shaft for the forward/reverse switching device is
A bevel gear loosely fitted on the horizontal shaft and the horizontal shaft connect the inner and outer sides.
Since it has a heavy shaft configuration, for example, a bevel gear that is interlocked with the input shaft is fixed to the horizontal shaft,
Then, the output from the horizontal shaft protruding from the rotary case is appropriately passed through a bevel gear type forward/reverse switching device, and then returned to the rotary case via a shaft parallel to the horizontal shaft that is interlocked with the horizontal shaft. The transmission structure is simplified compared to the rotary case, and the boss hole for the input/output shaft formed in the rotary case is
This has the advantage of simplifying the manufacturing process of the rotary case.

化を図れる利点がある。 Furthermore, since the forward/reverse switching device is installed in an auxiliary case that is separate from the rotary case, the work of assembling the forward/reverse switching device and the various transmission mechanisms inside the rotary case can be done separately. This has the advantage of simplifying the overall assembly work.
