Claims

[Scope of utility model registration request]

A spring made of a normal spring material and a spring made of a shape memory alloy are interposed to connect and support a bumper protruding from the front of the vehicle body to the front surface of the vehicle body, and a front obstacle object disposed at a predetermined position on the vehicle body. A sensor that detects the relative speed and distance of and a sensor that compares and calculates the detection output of the sensor and the setting output set by the setting device, and outputs a signal when the detection output of the sensor exceeds the setting output. A shock absorber for use in automobiles, etc., comprising a comparator, and means for heating the shape memory alloy spring to return the spring to its shape based on a signal from the comparator.
