To provide an ultrasonic flaw detection device capable of performing a correct flaw detection even on a tongue rail having an inclination portion.SOLUTION: An ultrasonic flaw detection device 10 performs a flaw detection of a tongue rail 2 having a top area part 2f and a first inclined surface 2g moving proximally toward a basic rail 1 continuous to the top area part 2f. The ultrasonic flaw detection device includes: a transmission probe T1 for irradiation with an ultrasonic wave from an irradiation part T1a formed approximately in a surface shape; a reception probe T2 for receiving the ultrasonic wave from a reception part T2a similarly formed approximately in the surface shape; and an attachment part 15 provided on either the transmission probe T1 or the reception probe T2, and having a first contact part 15a formed in the shape corresponding to the irradiation part T1a or the reception part T2a and a second contact part 15b formed in the shape corresponding to the side surface 2h of the top area part 2f and the first inclined surface 2g.SELECTED DRAWING: Figure 2
【課題】傾斜部を有するトングレールについても正確な探傷を行うことが可能な超音波式探傷装置を提供する。【解決手段】頭頂部２ｆとこの頭頂部２ｆに連続して基本レール１に向かって近接する第１の傾斜面２ｇを有する傾斜部２ｃとを有するトングレール２の探傷を行う超音波式探傷装置１０であって、略平面状に形成された照射部Ｔ１ａから超音波を照射する送信用探触子Ｔ１と、同様に略平面状に形成された受信部Ｔ２ａにより超音波を受信する受信用探触子Ｔ２と、送信用探触子Ｔ１及び受信用探触子Ｔ２のいずれか一方に設けられ、照射部Ｔ１ａまたは受信部Ｔ２ａに対応した形状に形成された第１の接触部１５ａ、及び頭頂部２ｆの側面２ｈ及び第１の傾斜面２ｇに対応した形状に形成された第２の接触部１５ｂを有するアタッチメント１５とを有する。【選択図】図２
