PROBLEM TO BE SOLVED: To reduce the risk that the driver's body accidentally comes into contact with an operation tool or the like when visually confirming the rear of the machine body from a driving section. SOLUTION: In a canopy 17 which covers the upper part of a driving part, a roof part 41 located above the driving part, left and right columns 42 supporting the roof part 41, and a roof part 41 with respect to the left and right columns 42 are separated. Left and right support portions 43 that support the holding portion 50 in a state in which the angle can be changed around the horizontal axis are provided, and the support portion 43 is provided with a holding mechanism 50 that holds the angular position of the roof portion 41. Further, a manual operation tool 62 that can be switched between a moving state in which the angular position can be changed by a manual operation and a position holding state in which the angular position is held is provided. The manual operation tool 62 is provided between the left and right columns 42. It is provided in the state of being located at.
