PROBLEM TO BE SOLVED: To provide a power supply bus connection structure which is easy to mount a power source module and a logic package to a casing. SOLUTION: In a connection structure of a power supply bus 10 used when a power source module and a logic package, etc., 27 are mounted to a device, a stepped shaft 3 having a plurality of large-diametrical portions is provided inside a guide rail 1 of the device into which the power supply bus 10 of the power source module and the logic package, etc., 27 is inserted, and the stepped shaft 3 is moved axially, whereby the large-diametrical portions move a plurality of wedge-like blocks 8 built inside the guide rail 1, and the wedge-like blocks 8 press the power supply bus 10 to the guide rail 1 so as to be connected. The stepped shaft 3 has a screw part and is rotated so as to move itself axially.
