Claims

[Scope of utility model registration request]

In a multi-layer cylindrical bearing, which is formed by winding a coated bearing material in which a sliding material is integrally applied on a steel plate into a cylindrical shape, and joining the abutting portions of both ends at a joint formed at the abutting portion, the joint portion comprises at least a pair of horn-shaped protrusions formed on the end surface of one abutting part, the tips of which are oriented in a direction that gradually moves away from each other; At least one pair of concave portions and at least one pair of horn convex portions whose tips formed on the end surface corresponding to the concave portion of the other abutting portion are oriented in a direction gradually approaching each other, and an inner surface of the convex portions are continuous with each other. The compound is composed of at least a pair of recesses whose bottom portions are oriented in directions gradually moving away from each other, and the horn-shaped projections and the recesses are engaged with each other and are plastically deformed to be integrally connected. Layer cylindrical wound bearing.
