Abstract

This invention relates to a handle device, in particular to one provided on a switchboard casing having such configuration that the engagement of a handle and a casing is not released even by the action of a raising spring and capable of forming a substantially large length of the handle to be gripped stably for the opening and closing operations of the handle. A pushbutton and a locking member are arranged at the most tip and an elastic body for locking, a connection member, and a lock member are arranged in a storage part at a tip of a handle rising due to the energization of a raising spring. Since the connection member is retracted in an unlock condition of the lock member, the locking member can be retracted against the energization of the elastic body for locking by pressing the pushbutton. Consequently, the engagement of the locking member and a casing with an engaging part is released so that the handle rises by a force of the raising spring. Since the connection member is retracted in a lock condition, the locking member cannot be retracted, the release of the engagement with the engaging part becomes impossible, and the handle cannot rise.
