請求の範囲第１項に記載の４点曲げ試験治具。[Claims for Utility Model Registration] (1) Both ends of a longitudinal test piece are parallel to each other.
The outer circumferential surface of two load pins that are parallel to the support pins are supported from the opposite side of the support pins at two locations separated in the longitudinal direction of the middle part of the test specimen. In a jig that performs a bending test by applying force in a direction in which the support pins and load pins are brought into contact with each other by a support device and a load device, respectively, two support pins and two load pins are respectively attached to the support device. four pin positioning grooves that accommodate the test specimen in a substantially immovable manner in the diametrical direction; and four pin positioning grooves that are perpendicular to the pin positioning grooves and that position and accommodate the test specimen in a substantially immovable manner in the width direction thereof; The intermediate pin member is positioned between the support pin and the support and/or the load pin and the load by the test piece positioning groove, and the intermediate member is positioned between the support pin and the load pin. The surface of the intermediate member that contacts at least the support pin or load pin and the intermediate pin is a flat surface, and the load applied from the support or load device to the intermediate pin is transferred to the support pin or load pin by line contact. A four-point bending test jig characterized by transmitting a signal to the user. (2) The four-point bending according to claim 1, wherein one set of the intermediate pin and the intermediate member are independently provided for each of the two support pins or load pins. Test jig.
