PROBLEM TO BE SOLVED: To provide a shock absorber capable of utilizing thermal energy obtained by converting vibrational energy.SOLUTION: A shock absorber 1 including an outer tube 2, and a piston rod 3 movably inserted into the outer tube 2, and generating a damping force for suppressing relative displacement of the outer tube 2 and the piston rod 3 includes a thermoelectric conversion element 4 provided on the outer periphery of the outer tube 2. The shock absorber 1 expands and contracts to absorb vibrational energy, which is converted into thermal energy. The thermal energy can be converted into electrical energy that can be utilized by the thermoelectric conversion element 4 in a wide range of devices, and the thermal energy is available. |
