Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a flat handle device in which the whole or the main part of the handle is stored in the front recess of the housing when the handle is not used. [Prior Art] There is known a flat handle device (for example, Japanese Patent Literature 1). When a handle is used, the handle rotates around the lateral pivot of the base end and protrudes from the front recess of the housing. On the other hand, it is not used. When the handle is held, the handle is stored in the front recess of the casing, and is locked in the storage position by a locking mechanism installed on the casing side. Recently, with regard to the flat handle device, it has been reported that improper unlocking has caused the lock mechanism to fail and the handle to protrude to the use position. This criminal method involves inserting the front end of a screwdriver into the gap between the end surface of the front end of the handle and the inner surface of the recess on the front of the housing, while slightly tilting the handle toward the front of the housing, while prying the front end of the screwdriver into the back of the front end of the handle, The screwdriver is pushed down by the principle of the lever, and the handle is forced to be pushed out, which causes the handle buckle part that is engaged with the hook body of the locking mechanism to violently rupture. In order to prevent such criminal methods, the aforementioned clearance may be eliminated or reduced to a minimum so that the front end of the screwdriver cannot be inserted, but in this case, the dimensions must be carefully managed when manufacturing or assembling the components. If the size management fails, the handle cannot be stored in the front recess of the case, or it can be stored but cannot be stored smoothly.
