Abstract
A control device case is disclosed which is comparatively small in size and is safe and easy to operate. The control device case includes a case body in the form of a rectangular hollow pipe having a substantially rectangular cross section. The case body has a printed circuit board holding structure formed on an inner periphery thereof for holding a printed circuit board on which an element which may generate heat is mounted. The case body has a plurality of cooling fins formed in an axial direction of the pipe on an outer periphery thereof for radiating heat generated from the element on the printed circuit board. The opposite ends of the case body in the axial direction are formed such that the length of a first wall of the case body is shorter than the opposing second wall of the case body. A pair of covers are mounted on the opposite end portions of the case body in such a manner as to cover over the opposite ends of the case body in the axial direction and each has an opening formed therein such that a member mounted on the printed board may be manually operated therethrough. The covers may be interconnected into a single cover.
