Abstract: An external power feeding apparatus is portable and mountable in a vehicle, incorporating a power supply unit, and capable of supplying power to outside. A pair of frameworks is arranged on both sides of the power supply unit to face each other at a predetermined interval and formed into a substantially rectangular frame shape. A first connecting member connects first sides of the pair of frameworks and is formed into a substantial U shape. A second connecting member connects second sides of the pair of frameworks, which are provided to intersect one end sides of the first sides and is formed into a substantial U shape. A third connecting member connects third sides of the pair of frameworks, which are provided to intersect other end sides of the first sides and is formed into a substantial U shape.

Abstract: A power conversion apparatus includes: a cooling air passage defined with cooling fins of upper and lower converters and cooling fins of an inverter opposed to each other; upper and lower blowing fans provided upstream of the cooling air passage; and upper and lower sucking fans provided downstream of the cooling air passage and at positions offset from the converters. The blowing fans are provided for supplying cooling air from upstream of the cooling air passage, and the sucking fans are provided for discharging air from within a casing of the apparatus to the outside.

Abstract: An engine generator movable on left and right wheels. The wheels are provided on a rear section of a bottom cover via an axle. A cylinder of an engine is disposed so as to incline upwards towards the direction of the axle. Inclining the cylinder lowers the center of gravity of the engine and disposes the axle positioned below the cylinder at a high position, thereby reducing the height of the engine generator. The orientation of the engine generator during travel is stabilized.

Abstract: An engine generator accommodating an engine and a generator inside a case. A first stationary handle that extends in the width direction is mounted in the rear section of the case. A second stationary handle is mounted on the upper front part of the case. A draw handle is provided so as to swing in the vertical direction in relation to the second stationary handle. The second stationary handle is manually grasped and the engine generator is moved. The first and second stationary handles are grasped and the engine generator is lifted. The draw handle is pulled to move the engine generator.

Abstract: An engine generator having a high-rigidity rigid skeletal member. A bottom cover supports the engine/generator unit. A wall-shaped vertical frame is disposed transversely of the engine generator in a front section of the bottom cover and rising from the bottom cover front section. A T-shaped center frame extends between a rear section of the bottom cover and the vertical frame. The skeletal member includes the bottom cover, the vertical frame and the center frame.

Abstract: A lawn mower comprises a power source for rotatably driving an output shaft, a housing having an interior space having a generally spiral-shaped portion, and a cutting blade disposed in the interior space of the housing and connected to the output shaft for rotation therewith to cut grass. The rotating cutting blade coacts with the spiral-shaped portion of the interior space to generate a swirling air flow that causes the cut grass to swirl within the interior space. A grass discharge passage communicates with the interior space of the housing and discharges therethrough grass cut by the cutting blade and swirling within the interior space of the housing. A pivotal shutter is pivoted about a generally vertical axis by manual operation of a control member to open and close the grass discharge passage. The pivotal shutter comprises a pivotal shaft and a unitary shutter member mounted on the pivotal shaft to undergo pivotal movement therewith for opening and closing the grass discharge passage.

Abstract: A lawn mower has a power source for rotationally driving an output shaft. A housing has an interior space having a generally spiral-shaped portion. A cutting blade is disposed in the interior space of the housing and is connected to the output shaft for rotation therewith to cut grass while the spiral-shaped portion of the interior space generates a swirling airflow allowing the cut grass to swirl within the interior space. An enclosure is connected to the housing and has a grass discharge passage having an inlet opening disposed in communication with the interior space of the housing for discharging grass cut by the cutting blade and swirling within the interior space of the housing. A guiding member is disposed in the interior space of the housing for gradually changing a direction of the swirling airflow and the swirling cut grass and for guiding the swirling airflow and the swirling cut grass toward the grass discharge passage of the enclosure.

Abstract: A cutter blade for lawn mowers having an airlift curved from a cutting edge formed on a rotationally leading edge toward a rotationally trailing edge. The trailing edge of the airlift is shaped in a waveform comprising a plurality of protrusions and a plurality of depressions. The protrusion closest to an outer end where the centrifugal force is greatest during the rotation of the cutter blade, is greatest in width so as to improve the discharging capability of grass clippings. The depressions limit negative pressure generated rotationally behind the airlift. A plurality of vent holes formed in the airlift is arranged radially in lines.

Abstract: A lawn mower has a scroll portion for allowing grass clippings to swirl within a housing while guiding them to a grass discharge passage. A guide provided beneath a top plate of the housing is placed along the scroll portion. A rear guide end of the guide is opposed to a passage opening facing the housing of the grass discharge passage. The direction of a swirling flow is gradually changed and guided toward the passage opening by the guide.

Abstract: An electric vehicle body has a curved portion provided with an opening. A storage compartment communicates with an inside of the body through the opening. A lid is disposed along the curved surface of the body to pivot about hinges to open and close the storage compartment. In one embodiment, each hinge includes a hinge pin provided on a side wall of the lid and a slotted aperture formed in a side wall of the storage box. The hinge pin is fitted into the long aperture in such a manner as to rotate and slide within the slotted aperture. As the lid is being opened, an edge of the rear cover proximate the lid comes into abutment with an edge of the lid to push the lid and hinge pin along a longitudinal direction of the long aperture.
