Locking plates 5 and 51 are embedded around the reinforcing plates 4 and 41, and the reinforcing plates are inserted into the locking holes 5a drilled in the locking plates 5 and 51 . Since the bent portions 4a of 4 and 41 are inserted and locked, even if high air pressure acts in the air chamber A of the main body 1 when using the bubble generator E, the main body 1 will not The locking plates 5 and 5 can prevent the shape from deforming and reduce the concentrated stress applied to the bent portion.
1 prevents the rubber from peeling off from the reinforcing plate, and there is no risk of it losing its shape due to water pressure or impact during ship navigation.
また、上述した補強板４及び４1に気泡発生孔
２を穿設する場合には、所定の直径よりも大きい
直径の孔２ａを穿設することが好ましい。 Furthermore, when forming the bubble generating holes 2 in the reinforcing plates 4 and 41 described above, it is preferable to form the holes 2a with a diameter larger than a predetermined diameter.
