掘削方向制御装置に送信している。2. Description of the Related Art Conventionally, an excavator having a built-in inclinometer is known. In this case, an inclinometer, a battery, a transmitter and the like are generally housed in a drill rod at the tip of the excavator.
Then, the output of the transmitter is transmitted to the drive and excavation direction control device of the excavation rod by being connected in the connected excavation rod by a cylinder or a transmission pipe having a coaxial cable and a non-contact resonance connection coil.

２２６１６８号）である。The inclinometer accommodated in the excavation rod at the tip of such an excavator is appropriately fixed to a storage portion of the inner cylinder, and the inner cylinder itself is excavated at a flange or the like provided at the upper end thereof. In general, the lower end of the storage portion is fixed to the end of the rod, and the lower end of the storage portion is supported in the lower end portion of the drilling rod via a spacer or the like (for example, Japanese Patent Application No. Hei 8-8300).

内端部に確実に固定することが重要となっている。By the way, since the transmission inner cylinder fixed and supported at the upper end of the excavation rod by such means is vibrated greatly by violent forward / reverse operation during excavation work, it is inserted and fixed near the inner lower end thereof. Since the inclinometer itself vibrates greatly and receives rapid acceleration, the mounting direction tends to be out of order, and the accurate mounting operation is not easy. For this reason, it is important to securely fix the inclinometer and the inner cylinder of the portion for storing the inclinometer to the inner end of the excavation rod using the spacer.

削方向に対して正しく設置されたことになる。Also, as shown by arrows in FIGS. 1 and 2, for example, the installation direction of the inclinometer must be correctly set in the X direction, which is the direction in which the auger is excavated, and in the Y direction, which is orthogonal thereto. In general, the inner cylinder accommodating the inclinometer or the like is fixedly supported in the lowermost excavation rod by spacers or the like in the upper end fixing portion and the lower end supporting portion. And since the support part and the spacer etc. of such an inner cylinder are originally created accurately, the inclinometer is accurately positioned in the storage part of the inner cylinder with respect to the support part of the inner cylinder including these spacers etc. If fixed, the inclinometer would inevitably be installed correctly in the direction of the auger excavation.

It has been extremely difficult to surely set and fix the supporting portions and the inclinometer supporting means fixed therein at the same angle. That is, when the inclinometer support means is fixed in the inner cylinder and the support portion is screwed into the inner cylinder, it is inevitable that some deviation occurs.
