は次式で表わされる。Reference numeral 16 denotes an endless elongated member made of a rope, and reference numeral 17 denotes an energy absorbing device on which the elongated member is mounted. This energy absorbing device has a lid 21 which is detachably attached to the main body 18 with screws 20.
Inside the main body 18, three mounting portions 22 projecting from a circular cross section for bending and mounting the elongated member 16 are formed integrally with the main body. Reference numeral 23 denotes two adjusting screws which are screwed into screw holes 25 formed in the lid 21 and penetrate therethrough. A pressing member 26 rotatably attached to the inner end presses the elongated member 16 with an appropriate force. The initial tension is applied.
By adjusting the initial tension on the side where the elongated member 16 enters the main body 18, it is possible to adjust a resistance force, that is, a tensile force, which is a frictional force between the elongated member 16 and the mounting portion 22. This tensile force becomes exponentially larger than the initial tension with respect to the total angle at which the elongated member 16 is mounted on the mounting portion 22. That is, when the initial tension F 0 , the total angle of the range in which the elongated member 16 is in contact with each of the mounting portions 22 is represented by θ in the arc degree method, and the friction coefficient between the elongated member 16 and each of the mounting portions 22 is represented by μ, the tensile force F

An extension portion 18 extending on both sides of the extension member 28 is a connecting member that connects the distal end portions of the extension portions. Reference numeral 30 denotes an engaging portion formed of a recess formed from the lower surface of each extension portion 27, and is detachably engaged with the hook portion 13. In this state, the main body 18 is supported by the support portion 14 and does not rotate downward by a predetermined amount or more.
The support part 14 may not be formed.

It is possible to exercise by repeating such operations. The movement of pulling out the elongated member 16 is a movement like rowing a boat or tug-of-war, and the pulling force is almost constant. In addition, the user can exercise such that the user pulls out continuously while grasping one side of the elongated member 16 alternately with the left and right hands. Also, the elongated member 16 can reciprocate so as to alternately pull out on both sides. Also,
The user can also use it while sitting on a chair.
