1. A low-profile air-conditioning register, comprising:
a retainer including an air passage having an outlet port at a downstream end of the retainer in a flow direction of air-conditioning air; and
an upstream fin and downstream fins located upstream of the outlet port in the air passage, wherein
the downstream fins include:
two facing first downstream fins extending in a longitudinal direction, and
two facing second downstream fins extending in the longitudinal direction of the first downstream fins on an upstream side of the first downstream fins,
each of the first downstream fins includes a fin shaft,
each of the second downstream fins includes a fin shaft,
a flow direction of the air-conditioning air that has passed through the upstream fin and has not passed through the second downstream fins is defined as an inflow direction,
the two first downstream fins and the two second downstream fins are each tiltable about a corresponding one of the fin shafts between a neutral position along the inflow direction and a tilt position tilted with respect to the inflow direction that approaches an inner side of the air passage toward a downstream side, and
the low-profile air-conditioning register further comprises a downstream gearing, wherein when one of the first downstream fins is tilted toward the tilt position, the downstream gearing holds, at the neutral position, an other one of the first downstream fins and one of the second downstream fins located at a diagonal position with respect to the other one of the first downstream fins and tilts, toward the tilt position, one of the second downstream fins located at a diagonal position with respect to the one of the first downstream fins.
