Abstract
An exercise assisting apparatus has a seat with a contact surface of which position is varied within an adjustable range defined by a user's physique in order to successfully adjust the user's knee at a desired bent angle irrespective of the user's height. The seat 21 bears the buttock of the user M with the user's feet resting on a foot supporting surface on top of a foot stand 40. The seat 21 is displaced by a seat driver 50 with a motor in a direction of varying the user's weight acting on the legs of the user M. The seat 21 is driven by an elevator mechanism 60 to move up and down together with the seat driver 50. The elevator mechanism 60 moves the seat 21 in a direction which is restricted to a line inclined rearwardly and upwardly with respect to a vertical direction and deducted by a user of maximum physique and a user of minimum physique.
