Load transmission mechanism unit for training device, and training device using same

A load transmission mechanism unit for a training device, comprising, in a housing portion:

• a grip shaft portion that rotates with a grip portion, which is configured to be gripped by a user, connected to a first end portion thereof;
• an intermediate shaft portion that rotates in conjunction with rotation of the grip shaft portion;
• a transmission portion suspended between the grip shaft portion and the intermediate shaft portion and transmits a mutual rotation of the grip shaft portion and the intermediate shaft portion;
• and
• a rotation conversion portion provided on a crank shaft portion orthogonal to the intermediate shaft portion and transmits rotation of the intermediate shaft portion;
• wherein the crank shaft portion converts 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,
• the first end portion of the grip shaft portion protrudes from a shaft opening portion formed in the housing portion in a direction orthogonal to the transmission portion, and
• the first end portion of the grip shaft portion is swingably supported by the housing portion, and a second end portion of the grip shaft portion on a side opposite to the first end portion swings within the shaft opening portion.
