PURPOSE: An umbrella stand installed to a heat duct for a bus is provided to prevent air and noise from flowing inside by opening a hole only when an umbrella puts into the umbrella stand and installing a drain cap. CONSTITUTION: A hole cover(10) is installed to a hole(3) of an umbrella stand to open only when an umbrella puts into. A drain rail(20) is installed along a heat duct(2) under the hole of the umbrella stand to collect water falling from the umbrella. A drain hole is formed to the drain rail.
