摘要:
A lawnmower including a cut grass storage container for storing cut grass. The lawnmower also includes a cutting blade, a downwardly-opening housing, and a cut grass conveyor passage. The cut grass storage container is provided to the cut grass conveyor passage. Grass that has been cut is delivered to the cut grass conveyor passage while revolving about a shaft inside the housing. A guide member is provided inside the housing. The guide member guides the revolving grass to the cut grass conveyor passage while guiding the grass to the outer periphery of the housing.

An electrode assembly of an alkaline secondary battery includes positive and negative electrodes disposed to face each other via a separator sandwiched therebetween. The separator has a dual-layer structure composed of a main-fiber nonwoven layer and an aromatic-polyamide-fiber nonwoven layer that are laminated in the thickness direction. The main-fiber nonwoven layer contains nylon as main fiber and does not contain aromatic-polyamide-fiber. In the electrode assembly, the separator is so disposed that the aromatic-polyamide-fiber nonwoven fabric layer faces toward the negative electrode.

The present invention aims to provide a sealed battery having superior performance due to favorable welding of a terminal of a seal cover and a current collector body provided below the seal cover, and a manufacturing method for the sealed battery. In the sealed battery, one of a positive-electrode plate and a negative-electrode plate is electrically connected, via a current collector body, to a terminal of a seal cover which seals an outer can. The current collector body is a single-piece plate member that has a main body and a tab extending from the main body. The tab passes through an insulating ring and bends back such that part of the insulating ring lies between a tip of the tab and the main body of the current collector body. The main body is resistance welded to the electrode assembly, and the bent back tab is resistance welded to the terminal.

A rotary lawnmower includes a shutter for switching a location to which grass cut by the blade is to be discharged, and a shutter operating mechanism for operating the shutter. The shutter operating mechanism has a first shaft, a second shaft, a first link arm, and a second link arm, a third link arm, and an operating lever. The first shaft is positioned on the housing. The first link arm is capable of swinging about the first shaft and has the operating lever. The second shaft is positioned adjacent to and parallel to the first shaft, is rotatably attached to the housing, and is linked to the shutter via the third link arm. The second link arm is attached to the second shaft in such a manner as to be restricted in relative rotation but capable of swinging about the second shaft, and is swing-driven by the first link arm.

A riding lawn mower having covers for covering the side part of a cutter deck and the side part of a transmission section. The covers have a plurality of small holes formed in a portion facing the side part of the cutter deck. The accumulation of grass clippings on the upper surface of the cutter deck and the transmission section is reduced, and the state of accumulation of grass clippings is confirmed via the small holes.
