We present the spatially resolved optical spectroscopy of the 12 arcsec × 24 arcsec Crab pulsar neighbourhood in the range λ λ 4600 - 5700 Å made with the Multipupil Fiber Spectrograph at the 6 m telescope of the SAO RAS. The spectra exhibit blue- and red-shifted strong [O III] and weaker Hβ and He II emission lines with the shifts and intensities varying with the position in the field. They hint the presence of a cone-like rotating structure centered at the pulsar position and oriented along the symmetry axis of the compact, torus-like pulsar nebula seen in optical continuum and soft X-rays. The kinematic structure is most likely associated with the pulsar nebula. If so, the compact nebular rotates counter-clockwise with respect to its symmetry axis, or the pulsar spin axis, and the estimated rotational velocity within cylindrical radii of several thousand AU from the pulsar is ~ 2000-3000 km/s.
