Abstract: A lubrication structure for an internal combustion engine includes an oil pump, a main gallery, an oil-supply passage, a sub gallery, and an oil-communication passage. The oil pump is installed in a crankcase configured by connecting an upper crankcase on a mating surface of a lower crankcase from above. The main gallery is provided in the lower crankcase for supplying oil from the oil pump to the engine. The oil-supply passage is provided in the lower crankcase and supplies oil from the main gallery to a mating-surface-oil passage of the mating surface. The sub gallery is provided in the upper crankcase for guiding oil to a piston jet that injects oil toward a piston of the engine. The oil-communication passage is provided across the lower and upper crankcases, branches from the oil-supply passage to communicate with the sub gallery, and guides oil in the oil-supply passage to the sub gallery.

Abstract: An electric vehicle that is able to effectively cool the inverter while incorporating the inverter in the swing arm, and enhance the strength of the swing arm. The electric vehicle includes a driving wheel, a hollow swing arm main body for supporting the driving wheel, and an inverter accommodated in the swing arm main body. The swing arm main body includes a plurality of arc-shaped heat radiation fins provided in a wall surface facing a side face of the driving wheel, the heat radiation fins being concentric with the driving wheel. The inverter is in contact with the back face of the wall surface.

Abstract: A lubrication structure for an internal combustion engine includes a crankcase, an oil pump, and a relief valve. The crankcase is configured by connecting an upper crankcase on a mating surface of a lower crankcase, and has an oil pan. The oil pump and the relief valve are installed in the lower crankcase. The oil pump sucks oil in the oil pan through a suction passage, and discharges the oil into a discharge passage. The relief valve performs a valve-opening operation according to pressure of oil in the discharge passage to return surplus oil in the discharge passage to the suction passage through a surplus passage. These passages are formed in the lower crankcase. A relief valve housing section housing the relief valve, and the surplus passage allowing the relief valve housing section and the suction passage to communicate with each other, are provided to communicate with the mating surface.

Abstract: In the oil lubrication structure that supplies lubricating oil to the transmission device, the oil lubrication structure includes an oil passage formed above a transmission device. The oil passage is formed by an oil groove portion and a plate member. The oil groove portion is integrally formed in a crankcase. The plate member is arranged in the crankcase so as to cover the oil groove portion. The plate member has oil dripping holes formed therein, and the oil dripping holes are opened at positions directly above the transmission device.

Abstract: To provide a vehicle that includes a balancer mechanism for reducing vibration of the engine and can leave a space margin for increasing the fuel tank in size and/or arranging equipment or components at the rear of the cylinder and above the crankcase. A vehicle includes: an engine mounted on a body frame. The engine comprises a crankcase with a ceiling wall, a crankshaft provided in the crankcase, and a balancer mechanism for reducing vibration of the engine by power transmitted from the crankshaft. The balancer mechanism comprises an idler gear disposed behind the crankshaft and rotated by power transmitted from the crankshaft, and a first balancer disposed behind the idler gear and rotated by power transmitted from the idler gear. The idler gear and the first balancer are disposed along the ceiling wall.

Abstract: A bearing unit structure includes a bearing and a bearing holding unit. The bearing rotatably supports a drive shaft. The bearing holding unit is provided to a crankcase so as to hold the bearing. A groove portion is formed on an inner peripheral surface α of the bearing holding unit, and the inner peripheral surface α faces the bearing. A thermal expansion correction band made of a resin is integrally formed with the bearing holding unit in a state of being embedded into the groove portion.
