Abstract
An object of the present invention is to provide a durometer enabling a contact portion in contact with an object to perform smooth piston motion. The durometer includes a main body unit including a movable unit pressed continuously against an object to be measured, a first sensor outputting acceleration information corresponding to an acceleration of movement of a contact part of the object to be measured in contact with the movable unit in a pressing direction, a second sensor outputting reactive force information corresponding to a reactive force at the contact part of the object to be measured in contact with the movable unit, a motor, a crank mechanism driven by the motor and causing the main body unit and the movable unit to perform piston motion, and at least one buffering member disposed on a periphery of the main body unit.
