The mechanism of p3He backward elastic scattering is studied. It is found that the triangle diagrams with the subprocesses pd3He\ensuremathπ0, \stackrel\ensuremath→pd*3He\ensuremathπ0, and p(pp)3He\ensuremathπ+, where d* and pp denote the singlet deuteron and diproton pair in the 1S0 state, respectively, dominate in the cross section at 0.3--0.8 GeV, and their contribution is comparable with that for a sequential transfer of a np pair at 1--1.5 GeV. The contribution of the d*+pp, estimated on the basis of the spectator mechanism of the p(NN)3He\ensuremathπ reaction, increases the p3\stackrel\ensuremath→He3Hep cross section by one order of magnitude as compared to the contribution of the deuteron alone. Effects of the initial and final states' interaction are taken into account.
