Hisato IMAEDA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A bellows (2) of a dust boot (1, 30) having large diameter parts (3) and small diameter parts (4) disposed alternately covers a piston rod (R) projecting from a cylinder (C). A bump stopper (B) fixed to the cylinder (C) projects into the bellows (2) as a projecting portion. The bellows (2) comprises a first section (M) which passes a projecting end of the projecting portion according to the elongation and contraction of the piston rod (R) and a second section (L) located therebelow. By making the small diameter parts in the second section (L) have a smaller inner diameter than the small diameter part located at a boundary between the first section (M) and the second section (L), the bellows (2) can be made slim without interfering with the bump stopper (B).
