The elastic support 28 a protrudes through the handle bar 23 to be movable forward/rearward and an elastic member 28 c, such as a spring, is disposed between the front protrusion and the handle bar 23. The fixing member 28 b is formed ahead of the elastic support 28 a and provides operation load by compressing the elastic member 28 c while the handle bar 23 moves forward (see (b) of FIG. 13). In this configuration, as the fixing member 28 b is thread-fastened to a fixing member support 28 d such that the position can be adjusted forward/rearward, it is possible to adjust the intensity of the operation load. That is, as the fixing member 28 b is moved rearward, the operation load is increased, while as the fixing member 28 b is moved forward, the operation load is decreased.
FIGS. 14 and 15 are views illustrating the structure of a safety device of the multifunctional twisting movement apparatus according to the second embodiment of the present invention.
As shown in FIGS. 14 and 15, the multifunctional twisting movement apparatus according to the second embodiment of the present invention includes foot plate caps 32 a, foot plates 32 b, and brakes 32 c to prevent an accident due to rapid turn when a beginner places the feet on the left and right foot plates 32.
The foot plate caps 32 a are the bases where the foot plates 32 b and the brakes 32 c are mounted. The foot plates 32 b are mounted on the foot plate caps 32 a such that the front portions can pivot up/down, such that the rear portions are placed to pivot up/down. The brakes 32 c are fastened to the rear ends of the sides of the foot plate caps 32 a and pivot from the lower portion when the foot plates 32 b come in contact with the foot plate caps 32 a. In detail, the brakes 32 c face down by lower support springs 32 d in a normal state, and when an external force is applied to the foot plates 32 b and the foot plates 32 b come in contact with the foot plate caps 32 a, the fixed brakes 32 c are operated, such that the lower support springs 32 d are compressed and the brakes 32 c pivoted forward from the lower portion.

That is, when the user gets on the foot plates for the first time, the left and right foot plates 32 can be prevented from rapidly turning left and right due to a friction force of a cover plate 21-1 being in contact with the lower portion. As the external force is applied, the brakes 32 c are gradually moved forward, and kept fixed at the front by the weight of the user exercising, without interfering with the exercise.
Further, even though the user gets off the foot plates after finishing exercise and the external force applied to the left and right foot plates 32 is removed, the friction force from the cover plate 21-1 is exerted by the operational features described above, such that the brakes 32 c are operated. Accordingly, it is possible to preclude an accident.
