PROBLEM TO BE SOLVED: To bring each probe positively into contact with underground buried material at the time of two probes penetrating into the ground and easily judges contact with the underground buried material. SOLUTION: A detecting part 2 of a probe penetrating device 1 is fitted to a track 4 through a robot arm 3. An oscillating probe 10 is fixed to a first housing 35 of the detecting part 2, and a vibration receiving probe 11 is fixed to a second housing 36. The respective housings 35, 36 are slidably enclosed in a casing 37. The center part of an oscillating member 46 is connected to the casing 37, and one end part of this oscillating member 46 is connected to the first housing through a first connecting member 47, while the other end part is connected to the second housing through a second connecting member 48. |
