Abstract
An opening/closing device for detachably coupling a closure member to the open edge portion of a body includes a locking shaft provided upon the side of the body, a bracket secured to the closure member and having a notch defined therein, an operating lever having an end portion provided with a pawl portion for engaging the locking shaft within the open end region of the notch, and spring means provided upon the operating lever for biasing the pawl portion in the direction of engagement with the locking shaft. When the closure member is set upon the body, the notch is engaged with the locking shaft. The closure member is closed relative to the body by the engagement of the notch and pawl portion with the locking shaft. When the closure member is opened in a cantilevered state, this device serves as a hinge. By operating the operating lever against the biasing force of the spring means so as to disengage the pawl portion from the locking shaft, the closure member is separated from the body.
