In the supporter for high-jumping competition, on one side of the main body attached to a pole to freely move up and down, a supporting part is provided while having a planar bar placing stage on an upper surface thereof and on the side symmetric with the supporting part, a lock part is provided while presenting a slope on one face and having a spring on an upper surface thereof. This lock part incorporates an operating button having a slope facing the said slope, having a long hole provided through a position parallel with the said slope and equipped with a half hole for fitting the spring on the eaves above the slope.
