摘要： An autonomous travel work machine includes a main body and a wheel, and is configured to execute a predetermined operation on an operation target while causing the main body to autonomously travel with the wheel. The autonomous travel work machine includes: an operation unit having a shape projecting from an upper face of the main body, the operation unit being operated by being pressed from an upper face side; and a protection unit located at a front side in a traveling direction of the main body relative to the operation unit, the protection unit being disposed at a height equal to or higher than an upper end of the operation unit.

摘要： A centrifugal pump includes an impeller rotatably disposed in a volute case for forcing a fluid to flow along a volute internal flow channel formed in the volute case, and first to fourth flow-channel recessed portions opening to the volute internal flow channel. The first and fourth flow-channel recessed portions are formed so as to be recessed in a direction substantially orthogonal to a direction of flow of the fluid. In a self-priming operation, the fluid is introduced into the first and fourth recessed portions whereupon the prime fluid is stirred within internal spaces of the first and second flow-channel recessed portions.

摘要： A mower capable of reducing noise generated by rotation of a cutter blade is provided. A mower is provided with an upper cutter blade and a lower cutter blade (15) inside a housing. The lower cutter blade has a wing portion (42) and a wing chamfered portion (51). The wing portion overhangs upward from a second rear end portion (47) of the lower cutter blade on an opposite side in a rotational direction, at both end portions (45) in a longitudinal direction. The wing chamfered portion is chamfered so that a wing outer end portion (53) of the wing portion is inclined from an upper surface to a lower surface.
