Claims

[Scope of utility model registration request]

Fluid torque converter, planetary gear mechanism,
In an automatic transmission equipped with a plurality of frictional engagement members for switching a power transmission path of a planetary gear mechanism, and a fluid-type actuator for operating on/off of the frictional engagement members, supplying and discharging fluid to the fluid-type actuator. a drive member that rotates the spool of the select valve; and a drive member that rotates the spool of the select valve; and a drive member that rotates the spool of the select valve; a vehicle speed sensor that detects that the vehicle speed is below a set vehicle speed; a stop operation detection sensor that detects the operation of a device to be stopped; and a condition that causes all of the outputs from the two sensors to be generated to drive the drive member. 1. A neutral control device for an automatic transmission, comprising: a controller that issues a signal to put the automatic transmission into a neutral state.
