Pedaling exercise device

A pedaling exercise device comprising:

• a rotation mechanism configured to pivotally support a rotation shaft to allow rotation;
• a pair of cranks having first ends connected to both ends of the rotation shaft of the rotation mechanism, respectively, extending in a radial direction of the rotation shaft, and configured to rotate about the rotation shaft;
• a pair of links having first ends rotatably connected to second ends of the cranks, respectively, and having second ends provided with wheels, respectively;
• a pair of pedal portions connected to the links along a longitudinal direction of the links, respectively, and configured to rotate in an elliptical orbit about the rotation shaft, respectively, by feet of a user depressing the pedal portions;
• a rolling surface connected to a first end of the rotation mechanism on a user side, and having an upper surface on which the wheels roll due to rotation of the pedal portions and reciprocation of the second ends of the links;
• and
• a restriction portion configured to restrict separation of the wheels from the upper surface of the rolling surface in a case where the first end of the rotation mechanism is lifted such that the rotation mechanism is erected in a state where a second end of the rotation mechanism is grounded, wherein
• the wheels have a central shaft,
• an extension shaft extending in an axial direction is connected to the central shaft of the wheels, and
• the restriction portion includes a magnet member provided on the upper surface of the rolling surface in a direction of the reciprocation and configured to attract the extension shaft of the central shaft of the wheels by magnetic force.
