ABSTRACT:
An adjusting device for a tread board of a treadmill has an actuating device, a transmission device and a connecting member. The actuating device is pivotally connected to a bottom of the tread board. The transmission device is connected to the actuating device. The connecting member is connected to the transmission device with a first end and has a second end pivotally attached to the tread board. The connecting member has a middle point pivotally attached to a stand. Accordingly, the actuating device and the transmission device can actuate the connecting member to rotate relative to the stand, and the angle of the tread board relative to the ground is adjusted. Because the transmission device can pivotally rotate relative to the tread board, a large force will not be applied to the transmission device. Consequently, the load bearing of the transmission device is reduced.
