PURPOSE: To obtain a biaxial cross type rotary cam which can keep surely the strength of the top end part of the rotary cam while preventing the interference of the top end parts of the rotary cam to be abutted on each other.

CONSTITUTION: In this biaxial cross type rotary cam, the abutting plane 13 of the other side rotary cam 11 is made in a plane like crossing by a right angle against the center line CL2, the abutting plate 12 of one side rotary cam 10 is made in a plane like abutting closely to the abutting plane 13, and a moving mechanism 42 consisting of a screw part 40 and a nut 41 is installed on the other side rotary cam 11. Therefore, when the rotary cam 11 is rotated in the R2 direction, the rotary cam 11 is moved in the arrow mark C direction by the moving mechanism 42, the anxiety of generating the interference on both rotary cams 10, 11 is eliminated, an outer plate of door 30 is let out easily. Because both abutting planes 12, 13 are the plane like, the strength of the rotary cams 10, 11 can be secured.
