Further, since the front end portion 700fe is shaped such as the circular arc along the trajectory T when the front wheel 20 is traveling, the lower protection is fixed thereto as compared with the case where the front end portion 700fe is shaped as a straight line The lower 134087.doc •13- 200932603 cover of the device 700 can be configured further. Therefore, the length of the two pedals 40 in which the main knight has placed the foot in the front and rear directions can be extended. In this embodiment, in the plan view of the lower protector 7〇〇, the front end 4 is shaped as a circular arc which is recessed toward the rear of the locomotive. Further, in the front view of the lower protector 7 该, the front end portion 700fe is shaped as an arc which is recessed toward the lower side of the locomotive 1 . Therefore, the front end portion 7 of the lower protector 700 can approach the front wheel 20 while avoiding contact with the front wheel 2〇. In other words, according to the lower protector 700, the lower cover 35 can be more reliably protected. In this embodiment, the gap G is formed between the lower cover 35 and the lower protector 700. Therefore, even when the sand and the like rolled up by the front wheel 2 are hit by the lower protector 700, the vibration transmitted to the lower cover 35 can be reduced. In other words, the lower cover 35 can be more surely protected. Further, since the vibration transmitted to the lower cover 35 is reduced, the vibration transmitted to the feet of the main knight placed on the footboard 40 can be reduced. Moreover, in this embodiment, when the screws 760 are locked to the nuts 77, a portion of the rubber covering the outer surfaces of the nuts 770 is located in the through holes (not shown). The vibration of the lower protector 700 can be prevented from being transmitted to the lower cover 35 while the lower protector 700 can be securely fixed to the lower cover 35. In this embodiment, the lower protector 700 has the raised portions 720 to 722 formed in the front portion 700f thereof. Further, each of the convex portions 720 to 722 has respective curved portions 72A to s formed therein, and the curved portions 720a to 722a are formed by bending the lower protector 7''. Therefore, the front portion 700f of the 134087.doc -14·200932603 which is easily hit by the sand and the like which is rolled up by the boring wheel 20 can be reinforced in rigidity. In this embodiment, the lower protector 700 extends to the side portions 35b, 35b of the bottom portion 35b of the lower portion of the lower cover 35. Further, the widest of the lower protector 700 A portion 73 is formed in the intermediate portion 700A of the lower protector 700, specifically, the center 700c in the front-rear direction. Therefore, the outer side portion of the lower cover 35 can be surely protected in the vehicle width direction.
