A ring insertion groove is formed between adjacent two of circular plates, which are made of a magnetic material and are arranged concentric with each other, and a ring, which is made of a non-magnetic material and has a larger deformation resistance in comparison to the magnetic material of the plates, is press fitted into the ring insertion groove. Thereafter, a peripheral part around an opening of the ring insertion groove is plastically flowed, so that a compression stress is left in the ring.

Electromagnetic clutch and manufacturing method thereof

A nozzle of an ejector depressurizes and injects fluid, which is supplied to the nozzle. The nozzle is received in a receiving space of a body. The nozzle and the body are formed by press working. The nozzle includes nozzle-side ribs, which extend in an axial direction and project radially outward. The body includes body-side ribs, which extend in the axial direction and project radially outward. In a predetermined cross section of each of the nozzle and the body, which is perpendicular to the axial direction and includes the corresponding ribs, the nozzle or the body is formed seamlessly as a continuous single piece member.
