Abstract
Official abstract text for this publication.
In a rotary connector where a moving body turning with the rotation and revolution of planetary gears and flat cables including inverted portions at middle portions thereof are received in a receiving space between outer and inner cylindrical bodies, a bottom plate of a stationary-side housing is provided with an annular protrusion that comes into contact with lower surfaces of the planetary gears and a hollow portion that is positioned outside the annular protrusion in a radial direction, and the hollow portion is positioned directly below in a vertical direction when the stationary-side housing is mounted on an installation portion of a vehicle. Accordingly, a foreign matter entering the receiving space falls down onto the bottom plate and is accumulated in the hollow portion. Therefore, the hindrance to the rotation of the planetary gears, when the planetary gears catch a foreign matter, can be prevented.
First claim
Opening claim text (preview).
What is claimed is: 1. A rotary connector comprising: a stationary-side housing where an outer cylindrical body is erected from an outer peripheral edge of a bottom plate; a movable-side housing that includes an inner cylindrical body facing the outer cylindrical body and is disposed coaxially with the stationary-side housing; flat cables which are received in a receiving space defined between the outer cylindrical body and the inner cylindrical body so that winding directions…
