Document Type and Number:
Japanese Patent JP7124684
Kind Code:
B2
Abstract:
To sufficiently reduce vibration of an engine.SOLUTION: A crank shaft device comprises a rotation sensor including a sensor plate rotating integrally with a crank shaft of an engine, and a detector for detecting a position from the sensor plate. In the crank shaft device, a mass body is provided at an outer peripheral part of the sensor plate, and the sensor plate and the mass body are configure to have a dynamic damper function with a resonance frequency almost identical to a bending resonance frequency of the crank shaft. The mass body is provided at the outer periphery part of the sensor plate, so that the sensor plate and the mass body can be made to function as a dynamic damper using a spring action in a face-titling direction of the sensor plate.SELECTED DRAWING: Figure 1
