Abstract
PURPOSE: To prevent swing or distorsion of a long bellows by disposing internal and external cylinders around the bellows and providing on the upper side of the internal cylinder, a waved guide which is loosely slidable up and down along the interiorly grooved external cylinder.
CONSTITUTION: A cylindrical guide 7 loosely encloses a bellows 4 slidable up and down along the inner face of an external cylinder 6. The upper end of the guide 7 is fixed to keep plate 5a. Several protrusions 7a on the outer face of the guide 7 are slidably put in a depression way 6c of the external cylinder 6. Under said construction, the bellows 4 having a tendency of swingingly contracting down when a rod 3 is pushed down is narrowly enclosed by the outer face of the internal cylinder 5 and the inner face of the guide 7, thereby preventing swinging of the bellows. Protrusions 7a on the guide 7 prevent its distorsion. Note that, to obtain stiffness of the bellows as high as withstanding a specific frequency defined by the Building Standards Act, thickness and length of the guide 4 are adjusted.
