摘要： PURPOSE:To provide a mold lubricant for hot forging which is excellent in lubrication and mold release characteristics and can be employed in high-speed and high-reduction hot forging, by dissolving or dispersing an alkali (alkaline earth) metal ligninsulfonate in a diluent. CONSTITUTION:A desirable mold lubricant for hot forging is obtd. by dissolving or dispersing at least one alkali (alkaline earth) metal ligninsulfonate (e.g., sodium ligninsulfonate or calcium ligninsulfonate), preferably together with an amine, in a diluent (e.g., water or oil). Examples of the suitable amine include ethanolamine, isopropanolamine, and dimethylethanolamine. The lubricant thus obtd. is applied between a mold and a material to be molded in conducting hot forging. It is excellent in lubricating properties for decreasing the friction therebetween and in mold release properties for decreasing the contact time therebetween.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle drive shaft 10 that is prevented from whirling under a floor of vehicle when an intermediate shaft 12 of the vehicle drive shaft 10 becomes the weakest part in the driving system parts and is broken.SOLUTION: The vehicle drive shaft 10 is configured such that the part 28 weakest in the parts from one end to the other end thereof is positioned in a positioning part inside a differential case 26 of a final reduction gear 22, accordingly the weakest part 28 positioned inside the differential case 26 is to be broken, in the event that an over-torque is exerted thereon. Even in the broken state, an end of the vehicle drive shaft 10 positioned on a vehicle inner side is held in the differential case 26, thereby preferably preventing the vehicle drive shaft 10 from swinging while being rotated and causing collateral damages during traveling of the vehicle.
