<p>A tilting and folding device of a treadmill includes a base 1 and a track bed 2 is pivotably connected to the base] by an arm 3, a support device 4 and an actuator 6. The arm 3 is pivotably connected between the base 1 and the track bed 2. The actuator 6 is pivotably connected between the base 1 and a pivotal portion 33 located between the first and second pivotal ends 31, 32. The support device 4 is pivotably connected to the base 1 and the track bed 2. When the arm 3 is pivoted about the second pivotal end 32 and driven by the actuator 6, the front end of the track bed 2 is lifted and stopped after being traveled to a pre-set stroke. When the actuator 6 continuously drives the arm 3, the rear end of the track bed 2 is supported by the support device 4 and pivoted until the track bed 2 is located upright.</p> |
