The front seat frame portion 12a which is a part of the front seat drive device portion 12 is toggled so that the front seat drive device portion 12 is not detached from the main body frame 11 when the front seat drive device portion 12 is attached to the main body frame 11. Since the pressing mechanism portion 11f that is pressed by the pressing hammer portion 11f1 is provided, the front seat drive unit 12 can be more securely fixed on the main body frame 11.

  In particular, the front seat drive unit 12 includes a drive source 12c. When the drive source 12c is an engine, vibration generated from the drive source 12c is large, and the pressing mechanism unit 11f is not provided. A backlash tends to occur between the main body frame 11 and the front seat drive unit 12. However, when the front seat frame portion 12a is pressed against the main body frame 11 by the toggle-type pressing mechanism portion 11f, the play between the main body frame 11 and the drive device portion 12 with the front seat can be prevented. As a result, in combination with the effect of the tension applying mechanism 11c, even when the automatic track bicycle 1 travels on the rail for the rail, even if a large or small vibration occurs, the drive unit 12 with the front seat is surely provided. The rotation of the drive source 12c can be transmitted to the front wheels 11a1, 11a2 and the rear wheels 11a3, 11a4 via the geared belt 11b3 passed to the drive gear 12c1 and the driven gear 11b2.

  In the description of the above-described embodiment, the geared belt 11b3 passed to the drive gear 12c1 and the driven gear 11b2 of the front seat drive unit 12 is pressed from above and below by the respective rollers 11c1 and 11c2, and the geared belt. The toggle type tension applying mechanism 11c that applies tension to 11b3 has been described. However, the present invention is not limited to this, and FIG. 14 (the state before pressing the geared belt 11b3) and FIG. As shown in the state after pressing the geared belt 11b3), the geared belt 11b3 is pressed from above and below so as to be sandwiched between the two rollers 11c4 to 11c7, and a stronger tension is applied to the geared belt 11b3. Of course, the geared belt 11b3 may be prevented from slipping.

  In this way, the pressing lever portion 11f2 and the geared belt 11b3 are pressed by the two rollers 11c4 and 11c5 and the rollers 11c6 and 11c7 that are spaced apart from each other from above and below to apply tension to the geared belt 11b3. Even when the distance between the drive gear 12c1 of the portion 12 and the driven gear 11b2 is long, it is possible to more reliably prevent the geared belt 11b3 from coming off.
