PURPOSE:To reduce heat generation due to longtime energization to a solenoid in a device for connecting and disconnecting a power take-off device through the energization of the solenoid, by energizing, upon completion of power connection, the solenoid with the use of the remaining power which is consumed through a resistor. CONSTITUTION:When a first switch LS1 is turned on by operating a clutch pedal after an oprating switch S is closed, a first relay LS1 is energized to turn on switches (r1), (r1') so that the relay R is self-energized. Further, due to the switch (r1) being turned on, a solenoid SOL is energized through a normally closed switch (r2) so that an actuator element 13 moves to the right. Therefore, a slider 8 is engaged with both intermediate gear 6 and spline 7 by means of a shifter 9, and therefore, rotation is transmitted from a drive gear 15 to an output shaft 3. Simultaneously, a second switch LS2 is turned on by an actuator element 12 to energize a relay R2 so that the switch (r2) is opened. Accordingly, the remaining power which is consumed through a resistor 22, is fed to the solenoid SOL. |
