An anti-harmful impact input device has one or more than one housing space formed in its main body. Each housing space accommodates at least one gravity buffer, and an elastic buffer is intercalated between the gravity buffer and the inner wall of the housing space. The gravity buffer is made of weights, lead beads, or other massive substance, and the elastic buffer is formed of two springs, rubber, cotton, foam cotton, or thermoplastic elastomer. Each of the two ends of the gravity buffer is connected to one end of the spring, whereas the other end thereof is mated to the inner wall surface of the housing space so as to suspend the gravity buffer in the housing space with the tensile force of the spring.
