Simple passage structure of a lock-up torque converter is disclosed. With this passage structure an output shaft without any circumferential groove can be used. The output shaft has an axial passage and a radial passage communicating with the axial passage. A first spacer is mounted within an annular space between the output shaft and a stationary sleeve to divide the annular space into a first annular chamber and into a second annular chamber. The first annular chamber communicates with the inside of a turbine runner, while the second annular chamber communicates with the radial passage of the output shaft and with a control valve. A second spacer is mounted axially spaced from the first spacer and forms with the first annular spacer the second annular chamber. The second annular chamber and the radial and axial passages of the output shaft provide communication between the control valve and a clutch chamber of a direct drive clutch.
