PURPOSE:To improve lubricating efficiency by making an oil hole of a main shaft and an oil hole of an intermediate section member communicate with each other via an oil groove which is provided on a slider, in a device which has the intermediate section member that has a pin part for connecting a connecting rod and the main shafts that are connected to both end sides of the intermediate section member via sliders. CONSTITUTION:An intermediate section member 1, which corresponds to an intermediate section of an Oldam's coupling, is composed of a pin part 2 with which a big end part of a connecting rod 8 is connected and a pair of disk parts 3, 4 that are formed to both end surfaces of the pin part 2. Guiding grooves 5, 6 which extend in the direction of rectangularly crossing with each other are formed on surfaces of the respective disk parts 3, 4. The first and the second main shafts 11, 26 are provided on the disk parts 3, 4 sides of the intermediate section member 1. The respective main shafts 11, 26 are composed of disk parts 12, 17, which slidingly touch the respective disk parts 3, 4 via sliders 16, 31 that are slidably engaged with the respective guiding grooves 5, 6, and shaft parts 13, 28. And oil holes 15, 9, which are formed to the first main shaft 11 and the intermediate section member 1, are communicated with each other by an oil groove 18 that is formed on the slider 16. |
