We investigate the kinematical properties of the L1521F-IRS in Taurus Molecular Cloud region using observations in HCN(J=1-0) hyperfine lines. 12m telescope of Arizona Radio Observatory was used. Observing coverage is about 3.7’×3.7’ area around the center of the target with 5×5 grid mapping. L1521F which harbors the faint infrared L1521F-IRS, displays a strong central concentration of integrated intensity in HCN without serious molecular depletion. We find that blue asymmetric and red asymmetric profiles are distributed in East-West direction, and that this distribution of HCN line profiles is well coincident with the conic shape of the Spitzer’s image of L1521F-IRS, confirming the existence of gaseous bipolar outflows emanating from L1521F-IRS.
