PROBLEM TO BE SOLVED: To provide an inexpensive and compact load loading device suitable for inspecting mechanical properties while applying a tensile load to a catheter and performing part of a manufacturing process.SOLUTION: A load loading mechanism 13 is provided that urges a second holding member 12 in a separating direction from a first holding member 11 and loads a tensile load when a catheter 1 is held by both holding members 11 and 12. The load loading mechanism 13 is constituted by a constant load spiral spring 15 capable of biasing the second holding member 12 in a direction separating the first holding member 11 out of a predetermined distance when the catheter 1 is held at both ends and the second holding member 12 is within the predetermined distance from the first holding member 11.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】カテーテルに引張荷重を加えながら機械的性質を検査したり製造工程の一部を実施したりするのに好適な安価でコンパクトな荷重負荷装置を提供する。【解決手段】カテーテル１が両保持部材１１、１２に保持されるとき、第２保持部材１２を第１保持部材１１から離隔方向に付勢し引張荷重を負荷する荷重負荷機構１３を備え、荷重負荷機構１３は、カテーテル１が両端保持され、かつ、第２保持部材１２が第１保持部材１１から所定距離内にあるとき、第２保持部材１２を第１保持部材１１から所定距離外に離隔する方向に付勢可能な定荷重渦巻きばね１５で構成されている。【選択図】図１
