PROBLEM TO BE SOLVED: To facilitate assembling work by solving the problem of being difficult for tension spring hooking work for a return between a chute and a chute guide; and to improve silence by solving the problem of resonating in the tension spring extended between the chute and the chute guide. SOLUTION: This snowplow has the chute 43 discharging removed snow to a distant place, first and second chute guides 61 and 62 determining the discharging snow direction by being bendably installed on the tip of this chute 43, and a return means returning these chute guides 61 and 62 to an initial position. This return means is a torsion spring 64 having one end extended to the chute 43 side and having the other end extended to the first chute guide 61 side. Collars (vibration reducing members) 71 and 71 reducing vibration of the torsion spring 64 are arranged in a coil part 93 of this torsion spring 64. COPYRIGHT: (C)2007,JPO&INPIT
