Road stud

A road stud, comprising:

• a base in which a coupling part is formed through a center of a body with an inner space formed, a mounting step is formed to protrude on an inner edge of the body, a locking step is formed to protrude inward in a state in which an outer upper end of the mounting step protrudes upward, a drainage path is provided in an outer direction of the body from an inner surface between the mounting step and the locking step, and a drain is provided in the form of a groove radially on a lower surface;
• a fixing portion in which an upper end is inserted and screwed into the coupling part of the base and a lower end is inserted into a groove formed at an installation part of a road so that the base is fixed to the installation part by curing a fixing member injected into the groove;
• a cap that has elastic restoring force and has a dome shape in which a flange is formed on an outer circumference so that the flange is fitted and fixed in the groove between the mounting step and the locking step of the base to generate air pressure by external pressure;
• a light reflection portion that is adhesively fixed to a height surface of the base and reflects ambient light;
• and
• a sound generation portion that directly radiates sound to the outside by air pressure generated while the cap is pressed while being fitted and fixed in a path passing through the inner space of the base from an outside of the light reflection portion and while pressing and fixing the light reflection portion to an outer surface of the base.
