shock load can be smoothly absorbed by a simple structure in addition since the shock load f can be absorbed only by the control lever unit 3 and the shaft 7 supporting the control lever unit 3 it is possible to substantially reduce the space to be prepared for displacement of the structural components as compared with the case in which whole transmission control apparatus should be displaced in order to absorb the shock load as in the prior art it is preferable to set the direction of the slots 5 a and 6 a i e the direction u201c a u201d at a direction of the lever of the control lever unit 3 extends while the vehicle is running forward and can be determined in consideration of positions the steering wheel or seats based on the vehicle according to the preferred embodiment of the present invention since the initial shock load is absorbed by the breakage of the structural parts and the second shock load is absorbed by the deformation of the structural parts it is possible to easily adjust the shock absorbing characteristics furthermore since the secondary shock load can be absorbed continuously over a predetermined stroke it is possible to smoothly perform the absorption of the secondary shock load although preferred embodiments are illustrated and described above it should be noted that the present invention is not limited to these embodiments for example it will be applied to a transmission control apparatus for a manual transmission arranged at an instrument panel of a vehicle in addition.
