Abstract:
1. A device for supplying snap rings, the device comprising: a magazine for containing C-shaped snap rings piled together, each of the snap rings being held in the magazine such that the gap is directed forward in a conveying direction; a conveying base having a conveying path on a surface thereof, the magazine being provided on the conveying base; an extrusion member that pushes out a snap ring occupying a lowest position in the magazine forward in the conveying direction along the conveying path; an oscillating member that is protractible and retractable with respect to a conveying surface of the conveying path at an area in front of the magazine in the conveying direction, the oscillating member being capable of entering the gap of the snap ring being pushed out so as to direct the gap forward in the conveying direction; a projection-strip guide wall that is defined between a pair of concave parts extending in the conveying direction in a termination area of the conveying path of the conveying base, the projection-strip guide wall being formed so as to stand upwardly in the substantially vertical direction, wherein the projection-strip guide wall has a width that permits the projection-strip guide wall to enter the gap of the snap ring; and a cover member provided on the conveying base in the termination area of the conveying path so as to cover the pair of concave parts and the projection-strip guide wall from above, wherein: the cover member has a pair of guide parts formed so as to protrude downwardly at positions whereat the pair of guide parts opposes the pair of concave parts; and each of the pair of guide parts has a contact surface that is curved so that a projection amount thereof increases toward a front in the conveying direction.
