Damper mechanism of bicycle frame

Abstract

In order to improve a running condition of a bicycle by absorbing shocks caused during the running and to reduce a manufacturing cost with a simplified structure, a damper mechanism for a bicycle frame comprises: a damper member interposed between connecting portions of a seat lug and a mono-seat lug, which damper member includes a base element facing to the mono-seat lug, and first and second hinge portions at an upper end of the base element, the first hinge portions being projected from a rear side of the base element so as to be movably pivotally connected to the connecting portion of the seat lug and the second hinge portion being projected from a front side of the base element so as to be movably pivotally connected to the upper portions of the mono-seat lug; and an elastic device disposed between the base element and the mono-seat lug.
