POWER TRANSMISSION DEVICE

摘要

A power transmission device having coaxially arranged drive side and driven side rotating members, a connection member for connecting both rotating members, and fixing members for fixing the rotating members and the connection member together. The power transmission member transmits power from the drive-side rotation member to the driven-side transmission member through the connection member, and, when the transmitted power exceeds a preset value, the power transmission member interrupts the power transmission by disengaging either of the fixing members from the connection member. The fixation member disengaged from the connection member is constructed from a columnar fixing member as a separate body from the rotation members and the connection member. The rotation members and the connection member are fixed together by axially staking the columnar fixing member such that the columnar fixing member is disengageable from the connection member. The durability and reliability of power interruption characteristics of the power transmission device are enhanced while preventing an increase in cost and size and impairment of easiness of assembling.
