PURPOSE: An apparatus for checking a slope of a waist is provided to maintain a correct posture of a waist by encircling an apparatus having a horizontal principle and sensing the state of a slope of a waist. CONSTITUTION: A closure(110) equips a detection sensor(112) in a center floor side of an internal space. A detecting part(120) informs a sensing state according to a variable slope of the closure to the outside. The detection sensor is made of a metal thin film. A control part(140) generates alarm or vibration when a horizontal state is released. The detecting part is formed to be rolled and rotated inside the closure.
