とから重量が重くなるばかりか、コストも高価と
なる問題があつた。 However, conventionally, when the gear unit is attached to the saddle body, the bracket of the gear unit is attached to the lower surface of the saddle body located below the axes of the first and second drive wheels so that the bracket protrudes downward. Therefore, the entire gear unit protrudes below the saddle body, and since the transmission shaft supported by the bracket is located at a lower position away from the saddle body, the transmission gear unit is interlocked with the first and second drive wheels. The body has a large diameter, and as a result, there is a risk that foreign objects may come into contact with the gear unit that protrudes below the saddle body, causing an accident.Furthermore, the large diameter of the transmission body increases the weight. Not only that, but there was also the problem of high costs.

護することができるのである。(Effects of the invention) As described above, the present invention has a rectangular shape and has a pair of opposing side walls with flanges on the upper and lower sides. a saddle body formed by supporting two running wheels in an opposing manner;
A motor for driving the first drive wheel, a reduction gear mechanism for transmitting the power of the motor to the first wheel, a pair of brackets, and a pair of transmission bodies rotatably supported between these brackets. in the saddle of a traveling crane comprising a transmission shaft having a transmission shaft and a gear unit for transmitting the power transmitted to the first drive wheel to the second drive wheel, the saddle of the traveling crane comprises a transmission shaft having and forming window holes extending from the lower part of the side wall to the middle part of the lower flange, and attaching brackets of the gear unit to these window holes to support the gear unit between the side walls; Since a guard portion extending downward from the lower part of the outer periphery of the transmission body is formed, the gear unit can be supported between the side walls while using a pair of rectangular side walls, and the structure is simple. , and the dimensions of the transmission body of the gear unit can also be reduced;
Weight reduction and cost reduction can be achieved. Further, since window holes are formed extending from the lower part of the side wall to the middle part of the lower flange, and the bracket of the gear unit is attached to these window holes to incorporate the gear unit, the strength of the side wall may be reduced. This means that the gear unit can be incorporated without having to do so. Furthermore, while supporting the gear unit between the side walls, the transmission body of the gear unit can be protected by the guard member formed on the bracket.
