Claims

[Scope of utility model registration request]

(1) A vertical flaw detection probe 7 that is brought into close contact with the end surface 1a of the axle 1 as an object to be inspected, either directly or through a spacer 10, and a beveled probe 7 that is brought into close contact with the end surface 1a of the axle 1 either directly or through the spacer 10. The flaw detection probe 8, the vertical flaw detection probe 7, and the oblique flaw detection probe 8 are connected to the end face 1 of the axle 1.
a single or common elastic body 11 that applies a biasing force in the direction of the end face 1a of the axle shaft 1; a portion 12 that holds the elastic body 11 so as to apply a biasing force in the direction of
a holder 12 having a portion 12C facing the outer peripheral surface of the axle 1 or the member 2 surrounding the axle; A measuring head for an ultrasonic flaw detector for an axle, comprising: an engaging body 13 which has elasticity and is removably attached to a side surface of a member 2 surrounding the body.

(2) The engaging body 13 includes a ball 13a that engages with a side surface of the axle 1 or a side surface of a member 2 surrounding the axle, and a core ball 1
a spring 13 that applies a biasing force in the radial direction of the axle 1 to 3a;
A measuring head for an ultrasonic flaw detector according to claim 1, which comprises: (b).
