CLAIMS
1. A fan comprising:
a boss having
a first end and a second end in an axial direction,
an inclined surface inclined, in a direction from the second end to the first end, toward an axial center extending in the axial direction, and
an outer peripheral surface located between the inclined surface and the second end, the boss being rotatable about the axial center;
a first blade member connected to the outer peripheral surface of the boss; and a second blade member connected to at least one of
the inclined surface or
the outer peripheral surface located between the inclined surface and a connecting portion where the first blade member is connected to the outer peripheral surface.
2. The fan according to claim 1, wherein
the second blade member has a centrifugal vane shape.
3. The fan according to claim 1, wherein
the second blade member has a propeller blade shape disposed on the inclined surface.
4. The fan according to claim 1, wherein
the second blade member continues to the inclined surface and the outer peripheral surface.
5. The fan according to claim 1, wherein
the second blade member continues to the outer peripheral surface.

6. The fan according to any one of claims 1 to 5, wherein
the boss comprises:
a central portion;
an outer peripheral portion located outward of the central portion and separated by a space from the central portion in a radial direction transverse to the axial direction of the boss; and
a rib located in the space and connecting the central portion to the outer peripheral portion in the radial direction.
7. The fan according to any one of claims 1 to 6, wherein
an edge of the first blade member is located away from a position of the first end of the boss toward the second end of the boss, with respect to the direction from the second end to the first end.
8. An outdoor unit comprising:
the fan according to any one of claims 1 to 7; and
a heat exchanger to exchange heat with air guided by the fan.
9. A refrigeration cycle apparatus comprising:
a compressor to suck in, compress, and discharge refrigerant;
a condenser to exchange heat with the refrigerant discharged from the compressor and thereby condense the refrigerant;
a throttle device to reduce pressure of the refrigerant condensed by the condenser; and
an evaporator to evaporate the refrigerant by exchanging heat with the refrigerant whose pressure is reduced by the throttle device,
the compressor, the condenser, the throttle device, and the evaporator being connected together by a pipe to form a refrigerant circuit,

the outdoor unit as recited in claim 8 being either the condenser or the evaporator.
