PURPOSE: To improve operability and reduce cost in a multi-shaft temporary fastening tool for rotatory-driving plural sockets simultaneously.

CONSTITUTION: A drive sprocket 15 rotated by a handle is journalled to the center of a housing 1, and five driven sprockets 23 connected to sockets are journalled in such a way as to surround the periphery of the drive sprocket 15. An endless chain 33 is then wound on the drive sprocket 15 and driven sprockets 23. A part of the endless chain 33 makes a detour onto the drive sprocket 15 side through intermediate sprockets 32. The drive sprocket 15 and driven sprockets 23 are thereby meshed on the inner peripheral side of the endless chain 33, and the rotating directions of the drive sprocket 15 and driven sprockets 23 can coincide with each other.
