Abstract: Provided is an electric pump having an elastic member that is not easily detached, and the housing formation cost is not high. The electric pump includes a pump body with a housing and an elastic member arranged on an outer circumferential surface of the housing. An elastic member arrangement portion is provided on the outer circumferential surface. A protrusion is provided on the elastic member arrangement portion. The protrusion includes a pillar portion and a fastening portion extending from the pillar portion. The fastening portion has a hook part. The elastic member has holes in two opposite ends, and the holes are engaged with the protrusion. The two opposite ends overlap with each.

Abstract: A wind portion of an insulator includes a side surface at the same side as, in a circumferential direction, a second guide surface which is orthogonal to a holding surface capable of holding a coil and which guides a winding in an inner-diameter direction, and an end surface orthogonal to the side surface. A first corner formed at a boundary between the holding surface and the side surface as viewed in the axial direction of a motor stator is located at a guiding-direction side by a first guide surface relative to a second corner formed at a boundary between the first guide surface and the second guide surface. The winding is extended from the second corner to the first corner.

Abstract: An insulator constituting a stator for a motor includes an extension portion that extends from a portion of a circumferential wall portion toward a plurality of terminals conforming to an axis line of the stator. A sealing member includes a cut-out hole in between an adjacent pair of the plurality of terminals, the cut-out hole being a through-hole extending conforming to the axis line. An end of the cut-out hole is blocked by an end surface of the extension portion.

Abstract: An exhaust system for discharging an exhaust gas of an engine includes a tail pipe 39 provided with a pressure control valve 1 which reduces an exhaust amount of the gas at the time of low load of the engine, and other tail pipe 40 not provided with the pressure control valve 1. An exhaust port 39a of the tail pipe 39 provided with the pressure control valve 1 faces downward as compared with an exhaust port 40a of the other tail pipe 40 not provided with the control valve 1.

Abstract: The stator of the electric motor comprises: a stator core; tooth sections being radially extended from the stator core; an even number of slots, each of which is formed between the tooth sections; an insulator covering the tooth sections; and motor coils being wound in the slots. The insulator has guide projections, each of which corresponds to each of the tooth sections so as to guide a magnet wire. The guide projections have guide sections, each of which includes a base end part and a front end part. In each of the guide sections, a radial thickness of at least one part located in the base end part is thin, a radial thickness of the front end part is thicker than that of the base end part. The guide sections are formed in same side faces of the guide projections arranged in the circumferential direction.
