Abstract
Abstract A sound insulating arrangement for a vehicle including a gear shift lever extending upward into the passenger compartment of the vehicle through an aperture formed in the floor panel thereof is disclosed. The arrangement comprises a shift lever boot having a bottom opening larger than the aperture and a top opening in fitting engagement with the gear shift lever and secured to the floor panel so as to cover the aperture. The arrangement also comprises a sound insulating plate having a center hole for penetration of the gear shift lever and a number of slits radially extending from the center hole for freedom of movement of the gear shift lever. The shift lever boot is provided at least partially with a bellows portion in one fold of which the sound insulating plate is fitted.
