<P>PROBLEM TO BE SOLVED: To provide a shock absorbing structure which does not easily affect frequency characteristics of external input transmitted to a sensor when the same is used as a support structure of a sensor, which easily restores shock absorbing function when the shock absorbing mechanism operates, and which can be miniaturized. Ž<P>SOLUTION: A friction generating surface 20 is formed on an inner wall of a cylindrical part of a sleeve shaft 2 by surface roughening treatment. A fixed shaft 1 and a sleeve shaft 2 are retained at an initial position by static friction force of the friction generating surface 20. When shock exceeding the static friction force is applied, the fixed shaft 1 and the sleeve shaft 2 relatively move from the initial position and stops movement at a position corresponding to elasticity of a spring 3. During the movement, dynamic friction force is applied on the friction generating surface 20, energy of shock is consumed in a period in which the dynamic friction force is applied, and the shock is absorbed.
