PURPOSE: A spring balance is provided to enable multi-directional confirmation of the weight of an object, thereby allowing different people to use the balance at the same time. CONSTITUTION: A spring balance(100) comprises a body(110), a spring(120), a connection part(130), observation grooves(140), and a measurement scale(150). The spring is installed inside the body to be extended and contracted. The connection part is provided on an end of the spring and connected with an object to be measured. The observation grooves are arranged along the perimeter of the body in order to confirm the extension and contraction of the spring. The measurement scale is formed around each observation groove in order to indicate the weight according to the extension and contraction of the spring.
