Claims

[Scope of utility model registration request]

In a center rotary in which a driven shaft at the center of the rotary shaft is driven by a bevel gear via a universal joint shaft and an intermediate drive shaft, there are mutually connected A mating cylindrical portion is formed to fit the two cylindrical portions, and a retaining member is engaged with the fitting portion to integrally and rotatably join the two divided portions. 1 drive shaft around the intermediate drive shaft
A forward/reverse conversion structure for a center rotary, which is characterized by being able to rotate the rotary by 80 degrees to enable forward/reverse conversion.
