PURPOSE: To make an assembling work easy, by forming a magnetic core in a shape such that magnetic poles project from the inner surfaces of both U-shaped leg portions of the core, and defining a gap between both magnetic pole surfaces of the magnetic poles for inserting a movable element thereinto.
CONSTITUTION: Diaphragms 3 are connected to both reciprocative ends of a movable element 2, and suction and exhaust operations are conducted by the displacement of the diaphragms 3. A core 11 of an electromagnet 1 is formed in a shape such that magnetic poles 14 project from the inner surfaces of both U-shaped leg portions of the core 11. There is defined a gap 15 between magnetic pole surfaces 13 formed at respective inside ends of both the magnetic poles 14. With this arrangement, the movable element 2 preliminarily connected to the diaphragms 3 may be inserted into the gap 15, thereby improving the workability of assembling.
