Abstract: The present invention relates to a stand for an outdoor unit of an air-conditioner. The stand has a support unit and a stand unit coupled by one touch to markedly reduce installation (assembly) time to greatly improve workability. Specifically, a plurality of movable fixtures made of ABS, a synthetic resin, or a metallic material are formed on the stand unit to stably fix brackets of an outdoor unit. Also, the movable fixtures can flexibly fix fixing different positions of outdoor units by manufacturer (manufacturing company) or product specification (can fix outdoor units on desired positions) to guarantee much better mountability and workability than conventional techniques by variable compatibility. Since the movable fixtures on which the outdoor unit is fixed can be slid on the stand unit, a work space can be easily secured to improve workability even if a coupling part of the outdoor unit fixed on the brackets is not loosened even if the outdoor unit is arranged in a small space to make after-service work difficult.
