PROBLEM TO BE SOLVED: To provide a gas pressure regulator capable of preventing mutual sticking of a switching lever and a body portion of a gas pressure regulator by freezing, in the gas pressure regulator having the switching lever switching a gas inflow inlet among a plurality of gas inflow inlets and facilitating the operation of the switching lever even though they are frozen. SOLUTION: When the gas pressure regulator 1 is viewed in a plain, a visible outline (a visible outline at a switching lever side) 43a for an edge 43a of an end of the switching lever 43 at a body portion 50 side, and a visible outline (a visible outline at a body portion side) 51a of the surface 51a opposite and adjacent to the edge 43a of the end of the switching lever 43, cross each other on a projected portion formed on the visible outline 43a a switching lever side.
