To miniaturize a clutch device and achieve low cost thereof.
A multiple-plate automatic centrifugal clutch device 37 includes: a plurality of drive plates 90 integrally rotatable to the side of a driven shaft 64; a plurality of driven plates 91 integrally rotatable to the side of a first reduction gear 75A; a clutch housing 87 housing the drive plates 90 and the driven plates 91 therein so that they can be overlapped alternately; and a centrifugal roller 88 which presses the drive plates 90 and the driven plates 91 to frictionally connect each other by the effect of centrifugal force generated by the rotation of the driven shaft 64, in which motive power is transferred from the driven shaft 64 to the first reduction gear 75A by the frictional connection of the drive plates 90 and the driven plates 91. The maximum movement restricting position for the centrifugal roller 88 which moves in the clutch radial direction by the centrifugal force is set to the outer side in the clutch radial direction than an inner circumferential surface 103A of an outer circumferential wall 103 of the clutch housing 87.
