Provided is a sacrum-pressing implement that can improve the transmission function between the upper half of the body and the lower half of the body and improve movement function by stabilizing the sacrum itself during exercise, including during rest. The sacrum-pressing implement (X) has a solid pole-shaped base (21) and a pair of protruding sections (22) that protrude with left-right symmetry from the two sides of the base (21). The distance between the respective outside surfaces (22b) of the pair of protruding sections (22) is configured to be smaller than the distance between a pair of posterior superior iliac spines (13), and the pressing surfaces (22a) of the pair of protruding sections (22) press only the sacrum (11).本發明,是提供一種藉由包含於安靜時也於運動時,使薦骨本身安定,而可改善上半身與下半身之間的傳達功能,並使運動功能提昇的薦骨推壓具。薦骨推壓具(X),具備有:實心柱狀的基部(21)、及從基部(21)的兩側部左右對稱突出之一對突出部(22);一對突出部(22)之各別的外側面(22b)彼此間的寬幅,構成得比一對髂後上棘(13)之間的寬幅還小,一對突出部(22)的推壓面(22a),僅推壓薦骨(11)。
