Abstract: An electric pump includes a housing having a bottom portion and an opening portion provided at an opposite side to the bottom portion, a motor rotor rotatably accommodated in the housing, a field coil, a pump rotor configured to transmit fluid by being rotated by a driving force of the motor rotor, and a control substrate provided at an outside of the bottom portion. The bottom portion includes a heat conduction wall formed of material including heat conductivity which is higher than heat conductivity of the housing. The housing includes a space portion formed with a flow path configured to allow the fluid to flow into the space portion and flow out of the space portion after the fluid is in contact with an inner surface of the heat conduction wall.

Abstract: A waterproof cover includes: a lid unit having a vent hole which allows an inner surface and an outer surface to communicate with each other, and configured to cover an electronic component; and a filter fixed to the inner surface of the lid unit in a state of facing an inner open end portion of the vent hole, and configured to block flow of a liquid while allowing air to flow therethrough, in which the outer surface of the lid unit has a surface area including a surface in which an outer open end portion of the vent hole is exposed, and the surface area has a region formed at a position adjacent to the vent hole and having a height different from a height of the surface.

Abstract: A pump includes a closed pump rotor being rotatably housed about a rotational axis in a pump space in a casing and including a shroud, a seal ring being shiftably provided, along the rotational axis, being coaxial with the rotational axis with respect to a cylindrical portion in a center of the shroud, and a shift mechanism configured to exert a shift force in a direction along the rotational axis with respect to the seal ring with rotation of the pump rotor and bring the seal ring into contact with an inner wall of the pump space.

Abstract: An electric pump includes: a pump main body that accommodates a pump unit and a motor; and a plate-shaped elastic member that is wound around an outer circumference of the pump main body such that a longitudinal direction of the elastic member extends along a circumferential direction of the pump main body, in which the elastic member is provided with a pair of first locking portions on both end portions in the longitudinal direction, and the outer circumference of the pump main body is provided with a pair of first locking target portions that are locked to the first locking portions.

Abstract: An electric pump includes a shaft, a rotor provided outward in a radial direction of the shaft, and to be rotated to the shaft, an impeller fixed to the rotor, and a cylindrical cap attached to a tip end portion of the shaft. A pump housing includes a suction port provided in an extending direction of the shaft, and a discharge port provided at one side of the impeller and in a direction crossing an extending direction of the shaft. The shaft includes an exposed portion at a tip end side further than a portion to which the cap is attached in the tip end portion. The cap is held by the shaft, prevents the rotor from moving toward a tip end side of the shaft, and includes, on an outer peripheral portion, a first taper portion being decreased in diameter toward the tip end side of the shaft.
