1. A fluid discharge device for discharging a fluid, comprising:
a duct defining a fluid flow passage and having an opening at a downstream end of the fluid flow passage; and
a grill portion disposed in the fluid flow passage to adjust a flow direction of the fluid blown from the opening, wherein
the grill portion includes a plurality of adjustment fins rotatably arranged on individual axes such that each fin of the plurality of fins rotates on a different axis in the fluid flow passage, and is provided with a plurality of sub-frame bodies defining a plurality of corresponding auxiliary flow passages that guide a part of the fluid flowing through the fluid flow passage to the opening, as an auxiliary flow, wherein each sub-frame body is directly attached to an end portion of a corresponding adjustment fin that is closer to the duct than a central portion in a longitudinal direction of the corresponding adjustment fin,
the auxiliary flow passages are configured with the adjustment fins to cause a flow direction of the auxiliary flow discharged from the auxiliary flow passages to be aligned with the flow direction of the fluid flowing through the fluid flow passage, and
the auxiliary flow passages overlap each other in a circumferential direction of the main frame body.
