Abstract:
In a coil spring of closed-end type, the coil spring is characterized in that a coupler is fixedly mounted between: an outer peripheral surface of a terminal convolution of a coil element rod; and, an outer peripheral surface of a subsequent convolution subsequent to the terminal convolution of the coil spring of closed-end type, whereby an amount of initial deflection is decreased.
