Control device for automatic transmission

A control device for an automatic transmission, comprising;

• a base member for mounting on a vehicle body;
• a shift lever pivotably supported at one of its ends by said base member,
• a positioning member movable substantially parallel to the longitudinal axis of said shift lever;
• a guide structure for guiding said shift lever, comprising a guide member having a parking position part and a moving position part for engaging said positioning member so as to guide said positioning member, said guide member provided at the moving position part with a buffer member for absorbing a shock when coming in contact with said positioning member, said guide member mounted on said base member;
• a check structure for moderating motion of said shift lever, comprising a check member and a check arm contacting said check member, said check member mounted on said base member, said check arm pivotably mounted on said shift lever and urged to said check member;
• and
• a shift-locking device for locking said shift lever, comprising a rotary bushing for blocking disengagement of said positioning member from said parking position part, said rotary bushing pivotably mounted on a fixed member other than said shift lever, and a shift-lock solenoid for pivoting said rotary bushing when releasing said shift lever from a locked condition, said shift-lock solenoid being mounted on a fixed part on said base member,
• wherein said guide member includes a plate member, and said buffer member is made of synthetic resin and is positioned on a contact side with said positing member in said moving position part.
