Electronic device comprising strap including structure to be detachably coupled to housing

Abstract

An electronic device includes: a housing including a pin; and a strap detachably coupled to the housing. The strap includes: a coupling groove that includes a first end that surrounds the pin and a second end that is open toward a first surface of the strap; and a button including an inclined surface that is inclined with respect to the first surface of the strap and slidable relative to the pin. A first portion of the button is movable into or out of the coupling groove, wherein a gap between the first portion of the button and an inner surface of the coupling groove is expanded as the button moves in a first direction toward a second surface of the strap opposite to the first surface of the strap, and wherein the gap is reduced as the button moves in a second direction opposite to the first direction.
