Claims

[Scope of claim for utility model registration] (1) In a part of the vehicle body close to the accessory drive belt,
A pivot device is provided in which the tip portion of the pivot device is rotatable in a direction toward and away from the belt, and the tip portion of the pivot device is provided with an engagement pulley that is able to freely rotate while in contact with the belt; A belt biasing force device is provided between the fixing device coaxially provided with the pivot device and the pivot device, which biases the pivot device to give a constant tension to the belt, and prevents load fluctuations of the auxiliary equipment. In order to forcibly alleviate belt vibrations caused by, for example, a vibration absorbing device comprising a movable member movable in the axial direction and an absorbing member is provided in the fixing device portion. Tension adjustment device. (2) A belt biasing device or a vibration absorbing device is provided on the outside of a housing that is integrally provided with the pivot device, and a vibration absorbing device or a belt biasing device is provided on the inside of the housing. A tension adjusting device for an auxiliary drive belt according to claim 1 of the utility model registration claim. (3) The tension adjustment device for an auxiliary drive belt according to claim 1, wherein the absorption member of the vibration absorption device is a compression spring or a viscous fluid.
