Further, the support roller 30 is rotatably attached to the peripheral surface portion of the fixed support member, and is rotatably supported on the rim 26 to thereby rotatably support the rim 26. The rim 26 may be rotatably supported by rotatably mounting a large number of rollers and rollingly attaching the rollers to the peripheral surface of the support member.
Further, the front wheel is composed of the tire 25 and the rim 26 similarly to the rear wheel and is attached to the frame by the fixed supporting member, but the front wheel may be composed of a wheel having a conventional spoke or hub. Furthermore, the motor 37 may be attached to the front wheels to serve as driving wheels. Further, instead of using the motor 37 as the prime mover, an internal combustion engine may be used. In this case, when the weight of the internal combustion engine itself is larger than the weight of the fuel tank containing the fuel of the internal combustion engine, it is desirable to arrange the internal combustion engine below the fixing member.

Also, since the prime mover is mounted on a fixed support member, the mounting mechanism of the prime mover can be simplified, and the drive transmission mechanism from the prime mover to the wheels can also be simplified as compared with the case where the prime mover is mounted in a rotating hub. it can. Furthermore, since the support member does not rotate, a battery or the like when a motor is used as a prime mover can be attached to the support member.

きる。Further, according to the invention of claim 2, the second drive transmission member of the second drive transmission mechanism for transmitting the power from the pedal is used for the first drive of the first drive transmission mechanism for transmitting the power from the prime mover. Since it can be arranged at a free position independent of the arrangement of the transmission member, for example, by setting the second drive transmission member at a position relatively close to the pen, the member such as the chain of the second drive transmission mechanism can be made compact. Is possible. Further, since the first drive transmission member can also be arranged at a free position independently of the arrangement of the second drive transmission member, in order to enable stable traveling with a low center of gravity, a relatively heavy weight such as a battery for a motor is used. Even when the large member is arranged at a relatively low position of the support member, the motor can be mounted at a relatively high position of the support member where a space remains.

In a two-wheeled or three-wheeled vehicle with a prime mover, a shock absorber interposed between the support member and the frame absorbs at least a part of the vibration of the prime mover attached to the support member, and the vibration of the prime mover is transmitted to the frame. Since it is made harder, damage to the frame due to vibration of the prime mover can be further reduced.
