EuYMnO
shows an antiferromagnetic transition below 
K. A spontaneous ferroelectric polarization 
along 
appears below 
K. The direction of then switches to 
below 
K. To investigate the relation between and the magnetic structure (MS), we have performed a neutron diffraction study using EXCED diffractometer installed at KENS spallation neutron facility of KEK. Magnetic Bragg peaks with a wave vector (0,0.31,1) were observed. By comparing a magnetic Bragg peak whose scattering vector 
is almost parallel to 
and that with almost parallel to , we have succeeded in observing the change of the MS at the temperature (
) where appears and at where changes its polarization direction. Our observations can be interpreted as formation of a spiral spin structure and change of its easy plane in response to the change of the dielectric properties.
