  • Patent number: 11152782
    Abstract: A drive device (9) drivably controls linear solenoid valves (SL1 to SL5) by inputting respective drive signals to one-side ends (5a) of the linear solenoid valves (SL1 to SL5) via a connector (Co) and wires (Ha). Other-side ends (5b) of the linear solenoid valves (SL1 to SL5) are connected to respective wires (56). The wires (56) are connected to the connector (Co) while being integrally commonalized by the common wire (57). This allows reducing the number of ground terminals gt of the connector (Co), whereby the connector (Co) can be downsized.
