This Letter theoretically discusses quasiparticle states and nuclear spin relaxation rates T_1^-1 in the quasi-one-dimensional superconductor (TMTSF)2PF6 under a magnetic field applied parallel to the conduction chains. We study the effects of Josephson-type vortices on T_1^-1 by solving the Bogoliubov– de Gennes equation for p-, d- or f-wave pairing interactions. In the presence of line nodes in pairing functions, T_1^-1 is proportional to T in sufficiently low temperatures because quasiparticles induced by vortices at the Fermi energy relax spins. We also try to identify the pairing symmetry of (TMTSF)2PF6.
