ABSTRACT:
A sealing structure for an automatic transmission shift control device comprises a boot interposed between a vehicle floor and a support member, which is a single piece resinous molding, of the transmission shift control device for providing a seal therebetween, and having on the lower side thereof a first seal projection in contact with the vehicle floor. A looped groove of a trapezoidal cross section is formed on the bottom of the support member. A second looped seal projection of a trapezoidal cross section and fittingly engageable in the groove in the boot is formed in the boot on the upper side of the boot. The first seal projection and the second seal projection are similar in loop shape and are located correspondingly on opposite sides of the boot.
