A tunnel playing facility (10) has multiple unit bodies (14) and a base part (12). Each of the unit bodies has a pair of columns (14a) and a dome (14b), wherein the columns and the dome are mutually connected by a proper method such as sewing. The unit bodies shaped into arches respectively and connected to each other form a tunnel by being arranged in parallel forward and backward. The base part having the unit bodies arranged thereon allows the respective unit bodies to maintain the tunnel stably. The unit body has an air hole (16) through which air is injected into the unit body or air inside the unit body is discharged. The tunnel playing facility further has a water supply apparatus (20). The water supply apparatus has a tube (22) with multiple water spray holes (24). One end of the tube is closed, and the other end of the tube is connected to a hose (28) by a band (26), wherein the hose allows water to flow from a water supply such as an external water supply source to the inside of the tube. The water supplied into the tube is sprayed into the tunnel, which is formed by the unit bodies of the tunnel playing facility, through the water spray holes (24). |
