Abstract: A load transmission mechanism unit for training device includes, in a housing portion: a grip shaft portion that rotates with a grip portion, which is gripped by a user, connected to a first end portion thereof; an intermediate shaft portion that rotates in conjunction with the rotation of the grip shaft portion; a transmission portion that is suspended between the grip shaft portion and the intermediate shaft portion and transmits the mutual rotation of the grip shaft portion and the intermediate shaft portion; a rotation conversion portion that is provided on a crank shaft portion orthogonal to the intermediate shaft portion and transmits the rotation of the intermediate shaft portion; and the crank shaft portion that converts the rotation of the crank shaft portion into a vertical movement of a sliding shaft portion disposed at a position parallel to the intermediate shaft portion.

Abstract: A sole and footwear provided with such soles are capable of properly controlling the movement of a foot pressure center, using a simple configuration. This sole includes: a sole body (41) which forms each bottom part of the footwear; and a foot pressure protrusion portion (43) which is provided in this sole body (41), and guides a foot pressure center corresponding to the center of a pressure applied to the bottom of each foot that moves when a person walks or runs, along a predetermined foot pressure center route from the heel toward the vicinity of the root of the fourth toe.
