Title:
POWER TRANSMISSION MECHANISM
Document Type and Number:
Japanese Patent JP2014194230
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress vibration resulting from a rotation variation of a crank shaft, and to enhance durability, in a power transmission mechanism which transmits a rotational force of the crank shaft to a balancer shaft.SOLUTION: A power transmission device 50 which transmits a rotational force of a crank shaft 10 to a balancer shaft 25 has: a first rotating body 51 having an internal peripheral face 68; a second rotating shaft 52 having an external peripheral face opposing the internal peripheral face; an outer magnet group 72 arranged at the internal peripheral face of the first rotating body; and an inner magnet group 76 which is arranged at the external peripheral face of the second rotating body, and magnetically acts with an interval from the outer magnet group 72. Respective magnetic pole faces included in the outer magnet group are larger than respective magnetic pole faces included in the inner magnet group in angle widths with a rotation axial line as a center.
