PROBLEM TO BE SOLVED: To provide a cushion spring lock structure of a vehicle seat which can properly prevent an anxiety that a resin coating of an end part of a cushion spring is easily exfoliated, and noise is generated at the elongation and contraction of the cushion spring by means which is simple in a constitution.SOLUTION: In a cushion spring lock structure A of a vehicle seat, at least a pair of opening parts 32 is formed in alignment at a frame 1 of the vehicle seat, a region between a pair of the opening parts 32 is made to serve as a spring lock part 30, and an end part 2a of a cushion spring 2 is locked to the spring lock part 30 so as to pass a pair of the opening parts 32. The cushion spring lock structure comprises a spring regulation salient part 31 which is protrusively formed at the spring lock part 30, and abuts on the end part 2a of the cushion spring 2 so as to regulate the deformation of the end part 2a of the cushion spring 2 to a longitudinal center part side of the cushion spring 2.SELECTED DRAWING: Figure 1

    【課題】クッションバネの端部の樹脂被覆が容易に剥離してクッションバネの伸縮時に異音が発生するような虞を、構成が簡易な手段によって適切に防止することが可能な車両用シートのクッションバネ係止構造を提供する。【解決手段】車両用シートのフレーム1には、少なくとも一対の開口部32が並んで形成され、かつこれら一対の開口部32の相互間領域がバネ用係止部30とされており、クッションバネ2の端部2aは、一対の開口部32を通過するようにしてバネ用係止部30に係止されている、車両用シートのクッションバネ係止構造Aであって、バネ用係止部30に突設され、かつクッションバネ2の端部2aがクッションバネ2の長手方向中央部側に変位することを規制可能にクッションバネ2の端部2aに当接するバネ規制用突出部31を、さらに備えている。【選択図】 図1
