1. A cooling apparatus for a hydrostatic transmission, comprising:
a cooling body to be coupled with a hydrostatic transmission;
a sidewall member configured to protrude from the cooling body to surround a cooling flow path which cools a working fluid supplied from the hydrostatic transmission and then discharges the working fluid into the hydrostatic transmission or a storage tank;
an installing member configured to protrude from the cooling body at a position spaced apart from the sidewall member to be disposed inside the sidewall member;
a detour member connected to the installing member and configured to protrude from the cooling body to extend in a first axial direction to allow the working fluid, which flows along the cooling flow path, to make a detour; and
a plurality of protruding members configured to protrude from the cooling body to be spaced apart from each of the sidewall member, the installing member, and the detour member in the cooling flow path,
wherein the protruding members are arranged in positions spaced apart from each other to form a through groove to allow the working fluid to pass therethrough.
