There is provided an apparatus for measuring force or hoop expansion force in the radial direction of the product and other SOLVED stent. [SOLUTION] and still one plate, a rotatable force units of one each end of the radially outer ends and the radially inner, at least which can be moved relative to the stationary plate at least (a), as well as a product engagement mechanism comprising connecting portion radially outward and the load elements each having a connecting portion of the radially inner coupling portion of the radially inner side of the load element, pivotally connected to a stationary plate the connecting portion of the radially outer side of the load element, rotatably connected to the force device, the end of the radially inner force devices and, adjacent to the boundary of the opening in the center of the product engagement mechanism But when rotated in a predetermined direction, and product engagement mechanism is adapted to engage with products to be disposed in the opening, a drive mechanism capable of rotating the (b) force unit, (c) a drive mechanism providing a power conversion mechanism for measuring the force required to electrically connect, to rotate the resultant force device. The In measuring the hoop force or expansion force in the radial direction by the device, and that provides a product engagement mechanism having the above configuration, place the product in the opening in the center of the product engagement mechanism, to rotate the resultant force device by, a force is applied to it via the ends of the radially inner segment to engage the product. Is regarded as an alternative to the radial expansion force of the product, the force required force necessary to rotate the force unit, that is to move the respective load element while pressing the product.
