Abstract: A joining structure of a power source and a transmission includes a joining portion joining a power source and a transmission to each other, the joining portion includes a first fitting portion centering a first housing and a second housing with each other, a second fitting portion where a rotary portion of the transmission is fitted to an output shaft portion of the power source, a housing spacer fixed to the first housing, and a third fitting portion including a protruding portion and a recessed portion, the recessed portion fitted to the protruding portion and centering the second housing and the housing spacer with each other, wherein in a case where the transmission is at a position where the protruding portion and the recessed portion start fitting to each other, the rotary portion is away from a position at which the rotary portion starts fitting to the output shaft portion.

Abstract: A control system of a power take-off (PTO) apparatus for taking off power from an automatic transmission by meshing PTO gear with drive gear of the automatic transmission includes a control unit, to which are inputted ON signal from PTO switch and vehicle-speed signal from vehicle speed detecting unit, for outputting actuating signal to actuating unit of the PTO apparatus. The control unit actuates the PTO apparatus by outputting the actuating signal to the actuating unit of the PTO apparatus in response to input of the ON signal from the PTO switch, and stops output of the actuating signal when a vehicle speed greater than a predetermined speed is detected during output of the actuating signal.
