<P>PROBLEM TO BE SOLVED: To provide a load measuring device capable of accurately measuring a load even if an eccentric load is applied, when measuring a highly accurate tensile load or a compressive load at deformation speed of a wade range including high-speed deformation. <P>SOLUTION: A load measuring device includes: a columnar load detector 2 for measuring a tensile load or a compressive load; a load measuring member 1 which has a contacting part 5 provided on one end side in an axial direction of the load detector 2 to apply the tensile load or the compressive load, and a supporting part 6 provided on the other end side; a cylinder part 3 which covers the load measuring member 1 around an axis of the load detector 2 without contacting with the load measuring member 1; and a plurality of rolling pieces 4 interposed between an inner peripheral surface of the cylinder part 3 and an opposite surface of the inner peripheral surface of the cylinder part 3 in the contacting part 5 and the supporting part 6 of the load measuring member 1. The rolling pieces 4 are arranged so as to roll in a direction for guiding the contacting part 5 and the supporting part 6 which are displaced by the load along the inner peripheral surface of the cylinder part 3 in the axial direction of the load detector 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
