Abstract
A wrist band for a device main body containing communication circuits, having a first wrist band at least partially covering a first antenna plate, a second wrist band at least partially covering a second antenna plate, and a clasp device including a contact mechanism for electrically connecting the first antenna plate and the second antenna plate to form a loop-like antenna when the second wrist band and first wrist band are clasped. The clasp device is releasable and has a three-fold stricture. The clasp device includes a clasp lower plate having a base end portion fixed to the first wrist band, a clasp intermediate plate connected to the clasp lower plate, a clasp upper box connected to the clasp intermediate plate and fixed to the second wrist band and a clasping lock mechanism that fixes the clasp upper box to the clasp lower plate when the clasp intermediate plate is rotated and overlapped onto the clasped lower plate. The contact mechanism includes a bare portion of the second antenna plate on an inner peripheral surface of the second wrist band and a projecting contact portion projecting from a top surface of the clasp lower plate and electrically connected with the first antenna plate, the projecting contact portion contacting the bare portion of the second antenna plate when the first wrist band and the second wrist band are clasped.
