Helmet

A helmet, comprising:

• a helmet body;
• a pad coupled to an inside of the helmet body;
• and
• a coupling member that separably couples the helmet body and the pad,
• wherein the coupling member comprises:
• a male coupling member disposed in one of either the inside of the helmet body or the pad, and
• a female coupling member disposed in the other of either the inside of the helmet body or the pad and the male coupling member is inserted and fixed into the female coupling member,
• wherein the male coupling member has a first inclined surface at a portion inserted and fixed into the female coupling member, and the female coupling member has a second inclined surface corresponding to the first inclined surface, and
• when an external force is applied to the pad in a first direction so that the male coupling member is separated from the female coupling member in a state in which the male coupling member and the female coupling member are coupled, the first inclined surface moves along the second inclined surface, and the pad is separated from the helmet body,
• wherein the male coupling member comprises:
• a base portion fixed to either the inside of the helmet body or the pad;
• an extension portion that protrudes and extends from one side of the base portion and has the first inclined surface on one side thereof;
• and
• an expansion end portion provided at an end of the extension portion in an extension direction, at least a portion thereof extending outward than the extension portion in a direction perpendicular to the extension direction,
• wherein the female coupling member comprises:
• a body having a receiving space to receive at least a portion of the extension portion and the expansion end portion and having the second inclined surface on one side of an inner wall of the receiving space, and
• an opening formed in the body in communication with the receiving space,
• wherein the expansion end portion passes through the second inclined surface and is inserted into the receiving space and is surrounded by the inner wall of the receiving space.
