In order to further understand the function, technical means, and expected effects of the various elements of the present invention, the following description is further described, and it is believed that the present invention will have a deeper and more specific understanding.

As shown in FIG. 1, FIG. 2, and FIG. 4, when the assembling of the treadmill with a built-in motor according to the present invention is completed, the output shaft 241 of the driving unit 20 is used to drive the front rotation shaft 12 to rotate, and the front rotation shaft 12 is rotated again. The running belt 30 can be driven to run relative to the chassis unit 11 and can provide an operator for brisk walking or running to achieve fitness purposes.

As shown in FIG. 4, the base 23 of the motor 21 is fixed on the beam 114, and the output shaft 241 of the main body 24 is interposed between the front rotation shaft 12 and the cross beam 114, and the main body 24 is interposed on the top. The function between the surface 116 and the bottom surface 115 can reduce the volume of the chassis unit 11 and reduce the space occupied by the chassis unit 11 in packaging, handling, and storage. efficacy.

In addition, as shown in FIG. 4, the bolts 235 are respectively inserted in the lock holes 234 and the long grooves 118, and the socket 232 can be operated along with the bolts 235 loosened. The longitudinal axis X slides with respect to the cross beam 114, the wheel distance between the second axis L2 of the output shaft 241 and the first axis L1 of the front rotating shaft 12 can be adjusted, and the tension of the transmission member 22 can be adjusted. After adjustment, these bolts 235 are tightened.

In summary, according to the present invention, the treadmill with a built-in motor can reduce the volume of the chassis unit 11 by using the configuration of the driving unit 20 and the beam 114, which can indeed achieve the purpose of the present invention.

However, the above are only examples of the present invention.
