<P>PROBLEM TO BE SOLVED: To prevent disconnection, by reducing stress applied to a lead wire, in a data transmission device of an internal combustion engine for transmitting measuring data detected by a sensor arranged in a piston. <P>SOLUTION: This data transmission device of the internal combustion engine includes: the piston 18 rotatably connected via a piston pin 47 to a connecting rod 21 connected to a crankshaft; the sensor 51 arranged in a predetermined position of the piston 18; a telemeter 52 arranged in the connecting rod 21 and transmitting the measuring data detected by the sensor 51; and the lead wire 53 for connecting the telemeter 52 with the sensor 51. The data transmission device includes a connecting rod side guide member 82 rotatably supported to the piston 18 on one end of a piston pin hole 46B for supporting the piston pin 47 and a piston side guide member 81 integrally supported by the piston 18 on the another end of the piston pin hole, and the guide members respectively support the lead wire 53. <P>COPYRIGHT: (C)2013,JPO&INPIT |
