Abstract: A method of manufacturing a hollow stabilizer includes a forming step of subjecting an element pipe to a bending process, to form a product shape including bent portions, and a quenching step of quenching the element pipe subjected to the bending process. In the quenching step, a cooling process is performed by immersing the element pipe made of steel in coolant and by spraying the coolant to an outer surface of the bent portion.

Abstract: A circuit member includes a metal base, an insulating layer, a conductor, and a cover layer. A termial portion of the circuit member includes a thick portion formed at a part of the insulating layer, a conductor convex portion which is a part of the conductor, and overlaps the thick portion, and a conductor extending portion. By the conductor convex portion and the conductor extending portion, a stepped side pad is formed. The stepped side gad includes a first surface along the conductor extending portion, and a second surface which rises in a thickness direction of the conductor extending portion. The stepped side pad and an element are connected by a conductive member.

Abstract: A stabilizer including: a main body for generating an elastic restoring force; and connecting portions formed on both ends of the main body and respectively connected to left and right suspension devices. Hardness of the connecting portions is lower than that of the main body. A method for manufacturing the stabilizer includes, in order, an entire body heat treatment process for heat treating an entire stabilizer and increasing hardness of the entire stabilizer, and a connecting portion softening process for heating the connecting portions and reducing the hardness of the connecting portions. The method for manufacturing the stabilizer thereby increases hardness of the main body and reduces the hardness of the connecting portions lower than that of the main body.
