Treadmill

A treadmill comprising:

• a frame;
• a deck having a plate shape and supported by the frame;
• a track belt rotating in an infinite orbit in a plate surface direction of the deck;
• and
• a shock absorbing portion located between the deck and the frame and configured to absorb a shock applied to the deck,
• wherein the shock absorbing portion comprises:
• a first anti-vibration rubber portion having a first surface and a second surface, the first surface being fixed to the frame, the second surface being fixed to the deck, and the first and second surfaces being parallel with the plate surface direction of the deck;
• and
• a second anti-vibration rubber portion having a third surface and a fourth surface, the third surface being fixed to the frame, the fourth surface being fixed to the deck, and the third and fourth surfaces being perpendicular to the plate surface direction of the deck,
• wherein the second anti-vibration rubber portion comprises:
• a first anti-vibration sub-rubber having the third surface;
• a second anti-vibration sub-rubber having the fourth surface;
• and
• a plate located between the first anti-vibration sub-rubber and the second anti-vibration sub-rubber, the plate having a greater hardness than the first and second anti-vibration sub-rubbers, and
• wherein the first anti-vibration sub-rubber, the plate and the second anti-vibration sub-rubber are arranged in order along a horizontal direction parallel to the deck,
• wherein the second anti-vibration rubber portion comprises:
• a first fixture coupled to the frame;
• and
• a second fixture coupled to the deck,
• wherein the plate is interposed between the first fixture and the second fixture,
• wherein the first anti-vibration sub-rubber is interposed between the first fixture and the plate, and
• wherein the second anti-vibration sub-rubber is interposed between the second fixture and the plate.
