Abstract
A watercraft propulsion device includes an engine, a drive shaft, a propeller shaft, a shift mechanism, an operation force transmitting mechanism, and a magnetostrictive sensor. The drive shaft transmits power from the engine. The propeller shaft is rotationally driven by power transmitted from the drive shaft. The shift mechanism changes a rotation direction of power transmitted from the drive shaft to the propeller shaft. The operating force transmitting mechanism connects to the shift mechanism and transmits a shift operation force to the shift mechanism to cause the shift mechanism operate. The magnetostrictive sensor detects a load acting on the operation force transmitting mechanism.
Claims7
A watercraft propulsion device comprising:
- an engine;
- a drive shaft that transmits power from the engine;
- a propeller shaft rotationally driven by power transmitted from the drive shaft;
- a shift mechanism that changes a rotation direction of the propeller shaft;
- an operation force transmitting mechanism that is connected to the shift mechanism and transmits a shift operation force to the shift mechanism to cause the shift mechanism to operate;
