PURPOSE:To attach and detach a base member and a projecting device to and from each other quickly and easily to improve the workability of assembling, by attaching a permanent magnet and a member to be magnetized to one and the other of them respectively to magnetize the member to be magnetized. CONSTITUTION:When a projecting device 9 is attached to a base member 6, their reference faces 7 and 10 are matched to each other. Then, a member 11 to be magnetized is attracted magnetically by a permanent magnet 8. When the device 9 is detached from the member 6, the device 9 is moved along the reference face 7 to shift the member 11 from the magnet 8. Thus, the device 9 is detached easily from the member 6. |
