The present invention relates to a bicycle pedal and shoe coupling device using magnetic force capable of effectively performing an exercise while increasing and increasing safety in a dangerous situation while driving.

In general, as modern people spend more time traveling by car, their walking or moving time gradually decreases, resulting in an extremely insufficient amount of physical exercise, resulting in aging and stiffness of muscles and easy fatigue, which causes adult diseases of modern people. being the main cause of it.

Therefore, by exercising regularly to train muscles and sweating, blood circulation and metabolism of the human body are promoted, while waste products are removed from the body to prevent muscle aging and stiffness, and high blood pressure, diabetes, Adult diseases such as heart disease and obesity must be prevented.

As interest in health has recently increased, the number of people who want to keep their health through exercise is rapidly increasing. Accordingly, the population using bicycles, which are not only an eco-friendly means of transportation but also a means of leisure, is rapidly increasing.

In general, when riding a bicycle, since the feet of a cyclist are not fixed to the pedals of the bicycle, they are prone to slip from the pedals and rotational force according to the foot motion of the rider is not sufficiently transmitted to the pedals.

In order to solve this problem, a technology has been developed that enables a rider to combine a bicycle shoe and a bicycle pedal with each other to increase a bonding force between the shoe and the pedal and to apply force to the pedal even when the bicycle pedal is raised upward.

As a prior art that has been disclosed in relation to a coupling device for coupling between bicycle pedals and shoes as described above, Korean Registered Patent Publication No. 1043323 (2011.06.15.) discloses a pedal shoe coupling device for coupling bicycle pedals and shoes with each other. The bicycle pedal includes a pedal body provided to be coupled to a pedal shaft of a bicycle, the shoe includes a shoe sole contacting the pedal body, and the pedal shoe coupling device includes the pedal body and the shoe sole.
