Abstract: A base plate of a motor includes an inner bottom plate portion and an elevated portion. A land portion is arranged on an upper surface of a portion of a circuit board which overlaps with the inner bottom plate portion in a plan view, or on a portion of the circuit board which overlaps with the elevated portion in the plan view. A conducting wire extending from a coil is electrically connected to the land portion. This structure enables the conducting wire to be connected to the land portion on the circuit board without the conducting wire being drawn outward beyond an outer circumferential end portion of the base plate. The axial position of the conducting wire connected to the land portion and the axial position of the base plate at least partially overlap with each other.

Abstract: A heat dissipation device includes a radiator, a first tank, and a pump assembly. The radiator cools liquid and extends in a first direction. The first tank is connected to the radiator, and the liquid passes through the first tank. The pump assembly is connected to the first tank and circulates the liquid flowing in from the first tank. The radiator includes a pipe through which the liquid passes. The pipe extends along the first direction. The pump assembly is located on one side in the first direction of the radiator. The pump assembly includes a first pump, a second pump, and a flow path portion. The first pump feeds and circulates the liquid. The second pump feeds and circulates the liquid. The flow path portion guides the liquid fed from the first pump and the second pump toward an outside of the pump assembly.

Abstract: A liquid feeder switches a flow path of a liquid having flowed in from an inflow port to one of a flow path communicating with a first base communication port and a bypass outflow path. When a pump is attached to a base, the bypass outflow path is closed to allow the liquid having flowed in from the inflow port to flow to the pump. When the pump is removed from the base, the bypass outflow path is opened to allow the liquid having flowed in from the inflow port to flow from the bypass outflow path to the outflow port. The liquid feeder is able to prevent liquid leakage when a pump of a liquid feeder is replaced or repaired.

Abstract: A gas dynamic pressure bearing includes a shaft centered on a central axis extending in an up-down direction, and a sleeve that faces at least a portion of the shaft in a radial direction. The portion in which the sleeve and the shaft face each other in the radial direction includes a first dynamic pressure portion at each of both ends in the axial direction, and a second dynamic pressure portion between the first dynamic pressure portions. In the first dynamic pressure portion, one of the sleeve and the shaft includes dynamic pressure grooves arranged in a circumferential direction. A sum of center angles of groove widths of the dynamic pressure grooves in a cross-section cut along a plane orthogonal to the central axis is about 144° or more and about 216° or less.
