するゼロラツシユアジヤスタ。[Claims for Utility Model Registration] A cylindrical body, a plunger slidably fitted into the body and having a low pressure chamber, a high pressure chamber constituted by the plunger and the body, and the low pressure chamber In a zero lash adjuster equipped with a check valve that selectively communicates between a chamber and a high pressure chamber, and a plunger spring that biases the plunger in a direction to protrude, the spring characteristics become stronger when the temperature is below the normal operating temperature. A zero lash adjuster characterized in that the plunger spring is formed of a shape memory alloy whose spring characteristics weaken when the temperature is above normal operating temperature.
