A vibration control structure includes a fixed member, an airbag device that is provided at a front portion thereof with a bag holder having a mounting hole and is disposed at a rear side of the fixed member, a horn switch mechanism that includes a support member supported by the fixed member in a state where the horn switch mechanism is inserted through the mounting hole and a slider disposed between the support member and the mounting hole so as to be slidable in the front-rear direction, and an annular elastic member that is disposed on the rear side of the bag holder while being mounted to the outside of the slider. The airbag device serves as a damper mass of a dynamic damper and the elastic member serves as a spring of the damper mass.
