Latest Patents
One of Sunami's latest patents is the "Elastic bush and method of press-fitting elastic bush." This invention features an outer sleeveless type resilient bush, where a resilient body is fixed to the outer circumference of an inner sleeve. The design allows the resilient body to contact the inside face of a support hole of an article to be supported. The inserted sleeve is embedded in the resilient body, with axial notches and split grooves formed on both components. Flanges that bend in the diametrically outward direction are created at both ends of the inserted sleeve, enhancing the bush's performance by increasing resistance to withdrawal from the support hole.
