Abstract: In a shift lever device (10), due to a tilt shaft (58) being nipped between peripheral surfaces of lower supporting holes (20) of a shift lever plate (12) and peripheral surfaces of upper supporting holes (38A) of a shift lever guide (26), a shift lever (52) is supported so as to be able to tilt around the tilt shaft (58). A shift position of the shift lever (52) is changed due to the shift lever (52) being tiltingly operated while being guided by a guide hole (30) of the shift lever guide (26) and passed within a passage hole (64) of a cover (62). Here, the strength of the shift lever guide (26) is made to be large as compared with that of the cover (62). Moreover, when load is inputted from the shift lever (52) to the shift lever guide (26), rotation of the shift lever guide (26) is stopped by the shift lever plate (12). Therefore, the shift lever (52) can be tiltably supported properly.

Abstract: Certain embodiments provide systems and methods for unlocking, opening, closing and locking a vent sash. The system may include a base configured to attach to one or more of a vent stop and a window frame. The system may include a lever pivotably or slidably attached to the base. The lever may be configured to pivotably attach to a locking mechanism interface of the vent sash. The lever may be configured to pivot substantially ninety degrees in a first direction to an unlocked position. The lever may be configured to pivot substantially ninety degrees in a second direction to an opened position. The lever may be configured to pivot substantially ninety degrees in a third direction to a closed position. The lever may be configured to pivot substantially ninety degrees in a fourth direction to a locked position.

Abstract: A swing lever structure for use in jacks comprises a swing lever including a coupling mechanism extendedly provided on one end thereof and having a stop plane formed on at lease one side thereof, and including a driving stem having a connecting end formed on one end thereof for pivotally connecting with the coupling mechanism of the swing lever, thus enabling a jointed rotation, the connecting end further including a stopping surface affixed on at least one side thereof relative to the stop plane of the swing lever, thereby the swing lever and the driving stem may be relatively rotated to form a preferred included angle therebetween so as to facilitate the operation of a jack in a narrow place.

Abstract: An air cleaner for a portable engine, includes an air cleaner case attached to an upper part of an engine body of the engine. Preferably, the air cleaner case is supported on an upper wall of a shroud covering the engine. Preferably, the air cleaner case is formed integrally with the shroud. Preferably, the air cleaner further includes an air intake structure divided into a plurality of intake passages having inlets displaced relative to each other with respect to an air flow direction in which an intake air flows.

Abstract: A driving apparatus includes a driving gear bidirectionally rotatable by a driving source, at least two driven gears selectively driven by the driving gear, at least two swing gears connected to the driving gear to operate in combination with the driving gear and to transmit a driving force of the driving gear to the driven gears, a swing lever pivotally disposed to support the swing gears, and an adjusting unit to adjust a swing position of the swing lever.

Abstract: A backpack-type working machine comprises an engine on a shouldering frame and a swingable arm on a side thereof. A throttle lever on the arm controls the engine. A base of the arm is connected to a holder by means of an elastic pivot means including a bolt around which the arm swings and a spring. To allow the arm to move on a plane orthogonal to a swing direction (plane including a center line of a pivot means), the holder and the base of the arm are connected such that only parts opposing and oppositely of inclined surfaces thereof are in partial contact with each other.
