Control device for automatic transmission

An automatic transmission control device for a vehicle comprising:

• a housing for including the transmission control device;
• a first rotary shaft supported on the housing and extended in a substantially widthwise direction of a vehicle body;
• a third rotary shaft extended substantially perpendicularly to a longitudinal direction of the first rotary shaft;
• a select lever being rotatable around both the first rotary shaft and the third rotary shaft for selecting one of range positions for an automatic transmission mode;
• a gate provided in the housing containing the range positions including a series of a parking position, a reverse position, a neutral position and a driving position for defining a selective operation of the select lever;
• and
• a shift lock system for prohibiting the selective operation of the select lever, the shift lock system comprising:
• a lock pin extending substantially in parallel with the first rotary shaft, the lock pin being movable in a lengthwise direction of the vehicle body with response to a rotation of the select lever;
• a second rotary shaft supported on the housing and extended substantially in parallel with the first rotary shaft;
• and
• a lock member with a base part having substantially semidisc shape and with a lock part configured along an edge of the base part and extending substantially in parallel with the second rotary shaft, the lock member supported on the second rotary shaft so as to rotate around the second rotary shaft to have one of a lock position and an unlock position, the lock position for prohibiting the selective operation of the select lever by bringing the lock part into contact with a periphery of the lock pin.

• second rotary shaft supported on the housing and extended substantially in parallel with the first rotary shaft;
• and
• a lock member which is rotatably supported on said second rotary shaft so as to rotate around said secondary rotary shaft to assume one of a lock position and an unlock position, and said lock member, which is rotatable about said second rotary shaft, being dimensioned and arranged to prohibit a plurality of improper selective operations of the select lever by bringing a lock part of said secondary rotary shaft into contact with a periphery of the lock pin.
