摘要： A walk-behind work machine having a foldable operating handle is disclosed. The operating handle is swingable and foldable about a first linking pin relative to a handle-attachment part of a work-machine body from a usage position to a storage position and can be locked in a usage position by a second linking pin. 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 in 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 distal end part is fit into the second pin-fitting hole, no gap is present in the second pin-fitting hole due to the tapered surface of the distal end part, and the operating handle is locked in the usage position.
