Claims

[Scope of utility model registration request]

A bottom plate carrying a sample and a push rod vertically erected above the sample and connected to a displacement detector at its upper end, and the bottom plate supported upward so as to be thermally expandable and suspended vertically in a heating chamber. a plurality of support rods, at least one of the push rods and the bottom plate is made of a material with a coefficient of thermal expansion greater than the coefficient of thermal expansion of the support rods, and the vertical direction of the one with the larger coefficient of thermal expansion is provided. A push rod type thermal dilatometer, characterized in that the dimension in the direction is large enough to offset the difference in thermal expansion with the support rod within the heating chamber.
