PROBLEM TO BE SOLVED: To provide a transducer protector capable of making welding strength at welding places of two housings uniform and preventing an occurrence of liquid leak.SOLUTION: An outer diameter 4OD of a first housing is formed so as to be smaller than an outer diameter 24OD of a second housing 22. The first housing 2 includes a first welding part 9 and a first stair part K1, and the second housing 22 includes a second welding part 29 and a second stair part K2. An outer peripheral edge part of a filter F is disposed between the first stair part K1 and the second stair part K2. A corner part D1R of the first welding part 9 and the second welding part 29 are welded by an ultrasonic wave so as to sandwich and fix the filter F.SELECTED DRAWING: Figure 1 【課題】二つのハウジングの溶着箇所の溶着強度を均一にでき、液体リークが発生することがないトランスデューサープロテクタを提供すること。【解決手段】第一ハウジングの外径４ＯＤは、第二ハウジング２２の外径２４ＯＤよりも小さく形成している。第一ハウジング２は第一溶着部９と第一階段部Ｋ１を有し、第二ハウジング２２は第二溶着部２９と第二階段部Ｋ２を有する。フィルターＦの外周縁部を第一階段部Ｋ１と第二階段部Ｋ２との間に配置し、超音波により、第一溶着部９の角部Ｄ１Ｒと第二溶着部２９とを溶着し、フィルターＦを挟持固定した。【選択図】図１
