PROBLEM TO BE SOLVED: To provide a position verification device installable in a reduced space by miniaturizing and assemblable easily. SOLUTION: This position verification device comprises: a pressure detection part S built in a pressure detection block B; a supply passage 1 connected to an air supply source for guiding compressed detection air; a blow passage 3 for guiding compressed blow air higher in pressure than the compressed detection air; a detection passage 5 communicating with the supply passage 1 and connected to the pressure detection part S; and a solenoid selector valve A allowing one of the detection passage 5 and the blow passage 3 to communicate with a jet hole formed in a table, and cutting off the other from the jetting hole. The pressure detection block B and the solenoid selector valve A are fixed to each other through a connection member X. The detection passage 5 is formed in the connection member X, and the pressure detection part S is connected to the port of the solenoid selector valve A through the connection member X.
