Title:

STRUCTURE FOR ATTACHING ELECTRIC DEVICE TO RAIL

Document Type and Number:

WIPO Patent Application WO/2011/021335

Kind Code:

A1

Abstract:

First engagement portions (9a, 9b) and second engagement portions (9c, 9d), which are opposite to each other and which have a hook shape, are provided on a housing bottom surface (3a). A rail edge portion (2a) on one side in the width direction of a rail (2) is hooked by and engaged with the first engagement portions, and a rail edge portion (2b) on the other side is hooked by and engaged with the second engagement portions. Further, a wire spring (10) which is angled is provided on the housing bottom shape. When the wire spring abuts against the end face of the rail edge portion on one side which is engaged with the first engagement portions, the wire spring is elastically deformed so that the inclination angle of the angled portion is reduced, and the biasing force of the wire spring is applied to rail. Thus, the rail edge portion on the other side is pressurized by the second engagement portions.
