To provide an aid for preventing slippage of a cap-type oxygen mask to which an existing oxygen mask is attached directly, and that can be attached and removed quickly, safely and securely without the oxygen mask being slipped even if one's head is moved with lying on one's back or even if one lies on one's stomach by being turned.
After cutting out a planar member to form H-shape, concavity and convexity for connection disposed at both ends of a front arm and a rear arm are configured to be adjusted according to the size of a head, a fixture for an rubber string being attached to each end of the rear arm, thus configuring the aid for preventing the slippage of the cap-type oxygen mask that is a three-dimensional structure independently assembled from an H-shaped flat surface without being integrated into an oxygen mask 11. To easily attach it to the existing oxygen mask 11 and remove from it, rubber strings 12 and 12' attached to both sides of the oxygen mask 11 are pulled and secured to the fixtures for the rubber strings disposed on the aid for preventing the slippage of a cap-type oxygen mask that is the three-dimensional structure assembled from the H-shaped flat surface, thereby preventing the slippage of the oxygen mask 11 without tampering with the oxygen mask 11.
