It is arranged in a line.

In consideration of the characteristics of the elliptical trainer 1, the plurality of magnetics 23 are magnets having the highest energy common point (25 m50 MGOe), and are highly dependent on temperature (80 ?? ˜200 ??), and have high oxidation power. It is desirable to use this strong neodymium magnetic.

In addition, the present invention has a plate 31, which is fixed to the upper surface of the horizontal base (5) and the wire cable 40 penetrates to one side, as shown in Figure 3, the upper surface of the plate 31 is a rotating disk 50 ) Is provided with a vertical bar 33 vertically adjacent to one side.

Furthermore, one side of the vertical bar 33 is rotated by adjusting the distance between the magnetic portion 20 and the rotating disk 50 by elastically pressing or releasing the pressure to the magnetic portion 20 toward the rotating disk 50 side.

First, in the case of setting the strength of the training intensity level, for example, from 1 to 8 levels, the initial state as shown in FIG. 6, that is, the minimum load is transferred to the rotating disk 50 as shown in FIG. The magnetic portion 20 is located far from the rotating disk 50 to facilitate the rotation of the.

In the initial state, as the rotary knob 13 of the strength setting unit 10 is set to a position corresponding to the first stage of strength, the wire 43 is released to release the first and second tension springs of the tension control unit 30. The second and third connecting frames 320 and 330 and the fourth connecting frame 340 are bent at a predetermined angle by the 313 and 323, and the contact part 361 of the pressing part 360 is the magnetic part 20.
