Then, insert a spring 8 for compensating the dead weight of the system including the tire bearing 4, etc., and use this spring 8 as appropriate to lift the system until the lower surface of the tire 3 is separated from the upper surface of the sample 2, or approximately. In addition to contacting with zero surface pressure, a pressing load spring 9 is inserted between the movable frame 6 and the lower end head of the piston 5'.

から定格値まで載荷されていく。 In the device of the present invention, the sample 2 and the tire 3 are separated from each other at first, and in this case, the self-weight compensation spring 8 in the load spring mechanism 7 is used to load the moving frame 6, the tire 3, its bearing 4, etc. The system is supported. Next, as the piston 5' is lowered, the weight of the system is gradually applied to the sample 2 as the deflection of the self-weight compensation spring 8 is restored and the pressing load spring 9 is compressed. By further pushing down the piston 5' after the entire weight of the system has been completely applied, the pressing force of the piston 5' is applied to the sample 2 via the pressing load spring, and as a result, the pressing force is applied to the sample 2. The load is 0
The load will be increased from 1 to 2 to the rated value.
