Provided is a rotating electric machine, including: a rotary shaft rotatably supported by a front bearing and a rear bearing; a field core firmly fixed to the rotary shaft; and a pulley fitted over the rotary shaft on one end side so as to be rotatable integrally with the rotary shaft. In the rotating electric machine, the pulley, the front bearing, and the field core are arranged in a stated order from the one end side of the rotary shaft toward another end side of the rotary shaft. The pulley is fastened to the rotary shaft with use of a male thread formed on the one end side of the rotary shaft and a nut to be mounted to the male thread. The rotary shaft has a flange portion, which projects radially outward, and is arranged to a position between the front bearing and the field core in an axial direction of the rotary shaft.

Rotary electric machine

A movable body that has a cylinder and a valve apparatus is accommodated inside an accommodating chamber of a pump body so as to cover a discharging orifice. A piston sucks a fluid into the movable body, and discharges the fluid from inside the movable body to the discharging orifice by being slid reciprocally through a piston sliding aperture of the cylinder. A relieving passage that communicates between a suction volume space of the accommodating chamber and the discharging orifice is formed between an inner surface of the accommodating chamber and the movable body by the movable body moving away from the discharging orifice in opposition to a force from a forcing body.

Electric-powered pump

The present invention attains downsizing of a permanent magnet with a simple structure to reduce a manufacturing cost thereof. Provided is a rotation angle detection device, including: a cylindrical magnetic circuit mounted to a shaft; and non-contact sensors provided in an inner void of the magnetic circuit, in which the magnetic circuit is composed of a first yoke and a second yoke formed of a magnetic material and having a pair of flat portions parallel and opposed to each other, and a pair of permanent magnets whose magnetic poles are aligned in the same direction so that magnetic fields whose magnetic fluxes are parallel to each other are generated in the void between the flat portions, and the non-contact sensor detects a rotation angle of the shaft by detecting a change in the direction of the magnetic fluxes.

Rotation angle detection device

A fuel supply apparatus particularly for the outboard motor is capable of decreasing the need to change the layout, etc., according to the specification of an engine to reduce the cost of production by preventing vapor from being discharged into an intake pipe. A low pressure fuel pump has its discharge flow rate adjusted to be greater than that of a high pressure fuel pump, and surplus fuel accumulating in a volumetric chamber is caused to circulate through the volumetric chamber, a first return passage, fuel piping, and an inflow passage under the action of the low pressure fuel pump, a check valve and a relief valve, whereby fuel remaining in the volumetric chamber is prevented from being locally warmed.
