PROBLEM TO BE SOLVED: To provide an explosion-proof constant angle turning device having improved durability and a reduced size for turning a rotated object accurately on a constant angle basis. SOLUTION: The explosion-proof constant angle turning device comprises a sliding table 58a to be reciprocatingly moved in a linear direction by air supplied thereto and having a pair of guide pins 59, an intermittent turn cam 60 arranged between the pair of guide pins 59 and adapted to be intermittently turned in a fixed direction with the reciprocating movement of the sliding table 58a, and the rotated object 52 to be linked with the turning motion of the intermittent turn cam 60. The intermittent turn cam 60 has a plurality of inclined faces 60a on a constant angle basis in the peripheral direction, on which the guide pins 59 abut to turn the intermittent turn cam 60. When the guide pin 59 thrusting the inclined face 60a is reversely moved, the turning motion of the intermittent turn cam 60 is stopped and the other inclined face than the inclined face 60a has attitude of facing the other guide pin 59.
