A treadmill includes a horizontal frame, an upright frame disposed upwardly on a front portion of the horizontal frame, and a horizontal deck laid over the horizontal frame and having a front portion connected pivotally to the front portion of the horizontal frame so that the deck can be turned upwardly on the horizontal frame to a folded position, where the deck abuts against the upright frame. A locking device includes a front tube having a front end connected pivotally to the rear portion of the horizontal frame, and a front positioning hole formed in a rear end thereof. A rear tube has a rear end that is connected pivotally to the rear portion of the deck, a front end that is connected telescopically to the rear end of the front tube so that the deck can be folded on the upright frame, and a rear positioning hole formed therein such that rotation of the deck to the folded position causes the rear tube to move away from the front tube. A spring-biased lock pin is disposed on one of the front and rear tubes, and is biased to extend through the front and rear positioning holes in the front and rear tubes when the deck is rotated to the folded position.
