Abstract

PURPOSE:To offset the expansion force of an expanding body by linking one end of tightly closed container to an upper fixed member, linking the other end and the attaching body with an upper expanding body, linking the attaching body and a lower fixing member with a lower expanding body, and providing communication for both expanding bodies by way of through holes. CONSTITUTION:Upper and lower fixing members 1 and 2 are linked with linking members 12. Two through holes 4 are provided in the member 2. A rising body 13 comprising a rod body 5 and upper and lower attaching bodies 18 and 19 is provided in the vicinity. The rod body 5 is inserted into the hole 4 so that the body is freely moved. A chuck 8 is provided at the tip of a supporting body 3, which is suspended from the member 1. A chuck 9 is provided at the tip of a supporting body 6 protruding from an attaching plate 18. An expanding body 14 is provided in the attaching plate 18 so that a supporting body 6 is contained. A tightly closed spherical container 11 accommodates the supporting bodies 3 and 6 and a test piece 10. The upper end is connected to the member 11, and the lower end is connected to the upper end of the expanding body 14. An expanding body 15 is provided between the lower surface of the attaching body 18 and the upper surface of the member 2. An air hole 17 is penetrated in the expanding body 14. Thus, the sucking forces of both expanding bodies are offset, and the net load of a weight 7 is applied to the test piece 10.
