<p><P>PROBLEM TO BE SOLVED: To accurately detect the friction force between a dummy road surface constituting body and a rubber testing body. <P>SOLUTION: In this rubber testing machine 1 equipped with the rubber testing body 3 and the dummy road surface constituting body 2 both of which come into contact with each other, the dummy road surface constituting body 2 or rubber testing body 3 is equipped with a detection means (sensor 5) directly detecting the force applied to the contact surface (peripheral surface 6) of the dummy road surface constituting body 2 with the rubber testing body 3. The detection means is installed in the installation hole formed to at least one contact surface formed to an uneven surface, and the detection surface of the detection means positioned so as to face the contact surface is preferably positioned so as not to protrude from the apex of a protruded part. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
