摘要： A power transmission unit (41a) includes a motor (70); and a transmission case (42a) to enclose an input shaft (72), an output shaft (60), and a gear mechanism (80) that transmits driving power between the input shaft (72) and the output shaft (60). A motor case (120) attached to the transmission case (42a) on a side opposite the gear mechanism (80) of the transmission case has a cylindrical shape whose cross section is constant throughout a direction orthogonal to an axial direction of the motor case, and the motor (70) is placed inside the motor case.

摘要： A control system (80) includes at least one continuously variable transmission (30, 31) drivingly connected to two left and right wheels (12, 13), an acceleration instruction unit (22, 23), a parking brake instruction sensor (52), a lawn mower (18), and a control device (40). The control device (40), during the drive of the lawn mower (18), stops the drive of the lawn mower (18) after the revolution speed of each of the two wheels (12, 13) or the revolution speed of the at least one continuously variable transmission (30, 31) has become zero (0) or within a predetermined range near zero (0), and during stop control of the lawn mower (18), drives the lawn mower (18) when a target revolution speed, issued by the acceleration instruction unit (22, 23), of the two wheels (12, 13) or of the at least one continuously variable transmission (30, 31) is not zero (0) and the operation of the parking brake is not instructed.

摘要： In a marine propulsion apparatus 18 that transmits power of at least one of an internal combustion engine (ICE) 16 and a generator motor (GM) 30 mounted on a ship 1 to a propeller 5 via a forward reverse switching mechanism 25, the marine propulsion apparatus 18 can be downsized as a whole. The marine propulsion apparatus 18 includes a connection switching mechanism 37 capable of selectively connecting the GM 30 to an upstream side 24a and a downstream side 24b of the power transmission from the ICE 16 in the forward reverse switching mechanism 25. Then, the forward reverse switching mechanism 25 is interposed between the ICE 16 and the connection switching mechanism 37, and a large torque from the ICE 16 is not directly transmitted to the connection switching mechanism 37. As a result, it is not necessary to increase the capacity of the connection switching mechanism 37, and the connection switching mechanism 37 and thus the marine propulsion apparatus 18 can be downsized.
