Abstract
Official abstract text for this publication.
A connecting shaft including a first shaft made of metal, a second shaft made of resin, and a collar made of metal including a first fitting portion fitting on an outer peripheral surface of the first shaft and a second fitting portion fitting on an outer peripheral surface of the second shaft. A gap between the outer peripheral surface of the second shaft and an inner peripheral surface of the second fitting portion is filled with an adhesive agent, and the adhesive agent is applied to an outer peripheral surface of the collar to cover an end face of the second fitting portion in an axial direction.
First claim
Opening claim text (preview).
What is claimed is: 1. A connecting shaft, comprising: a first shaft made of metal, the first shaft including a serration formed on an outer peripheral surface at an end part thereof, the serration including a first region and a second region; a second shaft made of resin, the second shaft including an inner peripheral surface fitting on the first region of the serration at an end part thereof; and a collar made of metal, the collar including a first fitting portion fitting on the second region of the serration and a second fitting portion fitting on an outer peripheral surface of the second shaft, wherein a gap between the outer peripheral surface of the second shaft and an inner peripheral surface of the second fitting portion is filled with an adhesive agent, wherein the collar includes a projection projected radially outward from an outer peripheral surface of the collar over a whole circumference thereof, and wherein the adhesive agent is applied from the gap up to the outer peripheral surface of the collar between an end face of the second fitting portion in an axial direction and the projection to cover the end face of the second fitting portion. 2. The connecting shaft according to claim 1 , wherein a diameter of an outer peripheral surface of the adhesive agent at the outer peripheral surface of the collar is equal to a diameter of the projection. 3. The connecting shaft according to claim 1 , wherein the projection is a first projection, the collar includes a second projection projected radially outward from the outer peripheral surface of the collar over the whole circumference, and the second projection is axially between the first projection and the first fitting portion. 4. The connecting shaft according to claim 3 , wherein an interfacing edge of the adhesive agent is located at a top of the first projection. 5. The connecting shaft according to claim 1 , wherein an anticorrosion coating is applied from the outer peripheral surface of the collar to the outer peripheral surface of the second shaft to cover the adhesive agent applied up to the outer peripheral surface of the collar. 6. The connecting shaft according to claim 1 , a diameter of an inner peripheral surface of the collar is expanded up to the end face of the second fitting portion.
