Each pressing piece 62 is used for pressing the track plate 52 and making the running belt 51 close to the supporting plate 42 of the supporting unit 4 so as to prevent the arc running surface 500 from deforming. Preferably, the pressing sheet 62 of each position-limiting pressing bar 6 has a buffer layer 621 for contacting the caterpillar board 52, a shock-absorbing layer 622 connected to the buffer layer 621, and a metal layer 623 opposite to the buffer layer 621 and connected to the shock-absorbing layer 622, in the first embodiment, the buffer layer 621 is made of bakelite, which has the advantages of smoothness, low friction and low hardness, so that the friction force when contacting the caterpillar board 52 can be reduced, and the abrasion can be further reduced. The shock absorbing layer 622 is made of foam and has the shock absorbing effect.
In detail, each of the limiting beads 6 has a pressing section 63 for pressing against the running section 501, and at least one raising section 64 connected to the pressing section 63, and a gap is maintained between the raising section 64 and the running section 501. As shown in fig. 5, each of the limiting beads 6 of the first embodiment has two raising sections 64, and the raising sections 64 are respectively formed at the front end and the rear end of the pressing section 63. The movement of the shoe 52 can be made smoother by the raised section 64.
Referring to fig. 8 and 9, a second embodiment of the present invention is shown, which is similar to the first embodiment, with the difference that:

The handle 204 has two connecting sections 206 respectively pivoted to the pivoting seats 201, and a holding section 207 connected to the connecting sections 206. The knob 205 is used to abut against the connecting section 206 of the handle 204 so that the handle 204 can be fixed to the pivot seat 201.
The armrest 204 is rotatable relative to the front upright 21 between a first position (see fig. 8) and a second position (see fig. 9), when the armrest 204 is in the first position, the grip section 207 of the armrest 204 is away from the rear upright 22, and the connecting section 206 abuts against the front bezel 202 to position the armrest 204. When the armrest 204 is in the second position, the grip section 207 of the armrest 204 is close to the rear pillar 22, and the connecting section 206 abuts against the rear baffle 203 to position the armrest 204, so that the second embodiment can be used for the user to run forward or backward.
In summary, the unpowered track type treadmill of the present invention uses the supporting unit 4 to support the tread section 501 of the track unit 5, and presses the track plate 52 through the limiting pressing bar 6 to maintain the profile of the arc-shaped tread 500, so that the overall structure is simple, the manufacturing cost can be reduced, and the purpose of the present invention can be achieved.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
