Claim 5:
6. A delivery vehicle comprising a rack, wherein:
the rack has:
a casing;
M pairs of supports, with M being an integer not less than three, that are provided inside the casing so as to extend in a depth direction and arrayed in M tiers at regular intervals in a predetermined direction that is one of an up-down direction and a left-right direction; and
a lock mechanism that locks returnable containers housed by being supported so as to be slidable along the respective M pairs of supports,

the rack being able to house all the returnable containers of one or more prespecified sizes;
the lock mechanism includes N shafts, with N being an integer not less than two and meeting N<M≤2N−1, that are movable in the predetermined direction and each have a stem that is provided so as to extend across all the M pairs of supports and M branches that branch off from the stem so as to correspond to the respective M pairs of supports;
moving each of the N shafts in the predetermined direction enables switching between engagement and disengagement between the branches of the N shafts and N holes provided in each of the returnable containers housed on the respective M pairs of supports; and
the branches are provided on the N shafts such that a combination of engagement and disengagement between the branches and the holes is different in each of the returnable containers housed on the respective M pairs of supports.
