Grease retainer
Grease retainer for the quickly detachable rear wheel hub, cataloged 1960-1969.
37-1143 is a grease retainer used on the quickly detachable rear wheel setup. It's part of the hub assembly, positioned to keep grease in the bearing area and keep it from migrating where it doesn't belong. This one turns up across catalog listings for the QD rear wheel from 1960 through 1969, including a version specifically noted as not for U.S.A. spec machines, so if you're sourcing this for a US-market bike it's worth double-checking against your parts book before you order.

The older reference for this part is W1143, which is the letter-prefix form you'll see in earlier parts books before the numeric system took over. Same physical piece, just a different way of writing it down.
If you're rebuilding a QD rear hub and this retainer is worn, cracked, or missing, it's a small item but one that matters for keeping the bearing grease where it needs to be. Give us a call if you're not sure which version your hub takes.
