    Abstract: An end turn portion of a coil spring includes a first portion, a second portion, and a third portion. The first portion is always in contact with a spring seat irrespective of the magnitude of a load applied to the coil spring. The second portion contacts the spring seat when the load applied to the coil spring is large, and is separated from the spring seat when the load is small. The third portion is always separated from the spring seat irrespective of the magnitude of the load. An insulating sheet made of a material having rubber elasticity is attached to a lower surface of a wire at the end turn portion by means of adhesive bonding. The insulating sheet is provided on a lower surface of a region including at least the second portion.

    Abstract: Provided is a stator core for a motor capable of facilitating an assembly work and parts management without increasing the number of components while suppressing leakage of magnetic flux passing through a flange to a coil. A stator core has an annular yoke portion and tooth portions inwardly protruding from an inner periphery of the yoke portion in a radial direction, wherein at a front end of the tooth portion inwardly protruding in the radial direction, a flange portion is provided so as to face a coil wound around the tooth portion and wherein to the flange portion, a compressive residual stress portion M is provided.

    Abstract: A coil spring includes a wire shaped to be helical, and is compressed between an upper spring seat and a lower spring seat. The coil spring includes an upper portion and a lower portion. A positive pitch winding end portion is formed on the upper portion of the coil spring. A terminal-point-strong-abutting-portion is formed at a distal end of the winding end portion. The terminal-point-strong-abutting-portion is in contact with the upper spring seat at one point at a position deviated to an inner side of a vehicle with respect to a coil central axis. On the lower portion of the coil spring, an end turn portion which contacts the lower spring seat is formed.
