1. A switch-equipped buckle device comprising:
- a tongue plate provided in a seat belt;
a buckle body which has a resin outer case, and to and from which the tongue plate is configured to be attached and detached in an attachment-detachment direction;
an ejector that is provided inside the outer case, the ejector sliding along the attachment-detachment direction of movement defined by the tongue plate from a detachment position where the tongue plate is detached from the buckle body to an attachment position where the tongue plate is attached to the buckle body, and the ejector sliding along the attachment-detachment direction of movement from the attachment position to the detachment position when the attachment of the tongue plate is released; and
a slide switch configured to detect a state of attachment of the tongue plate according to the detachment or attachment position of the ejector, wherein the slide switch includes a movable contact and a fixed contact, the movable contact of the slide switch is coupled to and movable with the ejector in the attachment-detachment direction of movement, the fixed contact of the slide switch is provided integrally within a bottom wall of the outer case and has an upper surface that is exposed at an upper surface of the bottom wall of the outer case, and wherein the upper surface of the fixed contact is flush with the upper surface of the bottom wall.

Abstract
A switch-equipped buckle device capable of accurately detecting an attachment-detachment state of a tongue plate by mounting fixed contacts immovably therein. The switch-equipped buckle device has, inside a buckle body, a slide switch that detects a state of attachment of the tongue plate according to the sliding position of an ejector. A slider of the slide switch is integrated with the ejector, and three fixed contacts of the slide switch are integrated with a lower case by insert molding.
