ABSTRACT:
A spring apparatus has a spring body including a plurality of elastic longitudinal beam members and a coupling beam member for holding the elastic longitudinal beam members at a predetermined interval. The apparatus further has a pair of spring retaining members for supporting the both ends of the spring body, and a rotary member rotatable provided around the central axis of the spring body as a center at least one one spring retaining member. At least one of the elastic longitudinal beam member is provided at one end of the rotary member. This spring apparatus is a tightly wound coil and made of the elastic longitudinal beam members in fully compressed state. When extended, each elastic longitudinal beam member is sequentially spirally deformed at larger pitch from the end. The twisting deformation of the elastic longitudinal beam member is released by rotation of the rotary member.
