PROBLEM TO BE SOLVED: To maintain an operation handle in a stable locking state relative to a handle-attachment part, while locking the operation handle to a usage position.SOLUTION: The operation handle 16 of the walk-behind work machine 10 can be folded about a first linking pin 41 from the usage position to a storage position with respect to the handle-attachment part 17 of a work-machine body 11, and adapted to be locked in the usage position with a second linking pin 51. The second linking pin is present on one of the operating handle and the handle-attachment part, and the distal end part of the second linking pin is formed into a tapered shape. The other of the operating handle and the handle-attachment part has a second pin-fitting hole allowing insertion and retraction of the distal end part. When the tapered face of the distal end part is fit into the second pin-fitting hole, the second pin-fitting hole allows the operating handle to be locked in the usage position. |
