摘要： PURPOSE:To provide a device for manufacturing a lockup piston, whereby any desired portion of the lockup piston can be hardened without being press tempered, resulting in reduced manufacturing costs. CONSTITUTION:A work rotation means 11 rotates the claw 6 of a lockup piston material 1a to a predetermined position where a partial heating means 12 is located. The claw 6 of the lockup piston material 1a is partially heated by the partial heating means 12. The heated portion of the claw 6 is quenched by a cooling liquid ejected from a cooling liquid ejection means 13, and part of the claw 6 is hardened. As a result, thermal distortion due to the hardening does not occur in the lockup piston material 1a except the part (hardened part) of the claw 6.

摘要： PURPOSE:To prevent the unevenness of strain in the heat stress caused by difference in cooling speed at the time of cooling in high temp. while restraining lowering of the hardness in the inner part, at the time of executing quenching. CONSTITUTION:A material to be quenched is dipped into high temp. coolant of mineral oil at the temp. C just below the starting temp. of martensitic transformation and thereafter, cooled by low temp. coolant of mineral oil at the temp. D lower than the temp. of the high temp. coolant. As the high temp. coolant uses the mineral oil having comparatively small heat capacity and the cooling speed is not so fast, partial temp. difference is small and the unevenness of the strain caused by the heat stress is small. Further, as the temp. of the high temp. coolant is set at the temp. C just below the starting temp. of the martensitic transformation, the cooling speed is not so low and lowering of the hardness can be restrained. Further, as this material is cooled by the low temp. coolant, without receiving the influence from the outer part, the deviation in strain caused by the martensitic transformation is small.

摘要： PROBLEM TO BE SOLVED: To provide a friction pressure welding member whereby both man-hours and component items are reduced in number, while obtaining high bonding strength, and also to provide a differential gear equipped with the member.
SOLUTION: A differential case 3 is fixed in a state that an annular projection 2d of a differential gear 2 and an annular projection 3d of a differential case 3 are brought into pressure contact with each other in an axial direction under a constant pressure, and then the differential gear 2 is rotated. As a result, friction heat is generated by the rotation at a pressure contact part of the annular projections 2d and 3d and the pressure contact part is heated. By increasing the pressure (upsetting) between the annular projections 2d and 3d, a burr 12 including an oxide or the like on a surface of a heated section is generated. The burr 12 is housed and sealed in spaces 10 and 11. Consequently, newly generated surfaces which appear in the heated contact section of the protrusions 2d and 3d are respectively welded by friction pressure.
