Abstract: A vehicle steering wheel structure which, while having a configuration in which small damper masses are arranged in a distributed manner, can secure the same highly efficient vibration reducing effect as when a large damper mass is arranged, without increasing the required installation space and the cost. The vehicle steering wheel structure includes a plurality of damper masses arranged so as to be distributed in an inner region of a rim portion of a steering wheel; a connection member that connects these damper masses; and a damper module disposed in the inner region of the rim portion.

Abstract: A steering wheel device that can absorb an applied impact load. A steering wheel device includes a lower cover that covers a steering column side of the steering wheel. The lower cover includes: a bottom member facing the steering column; an open portion which at a center of the bottom member and through which a steering shaft passes; slit portions formed on both sides, the slit portions being bent and curved in predetermined shapes; buffer portions formed in the bottom member and outlined by the slit portions, the buffer portions having a free end formed on a vehicle front side and a stationary end formed on a vehicle rear side; and bridge members that can be broken and bridge each of slit portions on the free end side of each of the buffer portions.
