    摘要: The invention relates to a boring element of a ground boring device, comprising a housing and a transmitter arranged in a receiving element of the housing, said transmitter being mounted in the receiving element in such a way that it can move in the longitudinal axial direction of the boring element, and is connected to the housing by a front-side buffer in such a way that the transmitter, when there is a rear percussive impulse on the boring element, moves towards the rear in the receiving element, as a result of a deformation of the buffer, without the transmitter coming directly into contact with another part of the boring element.
