BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for arranging a transmission control cable of a vehicle for connecting a transmission and a change lever of the vehicle.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS.
A mount bracket 102 is mounted on a floor panel 101, and lower ends 103a, 103a of instrument panel floor braces 103, 104 extending downward from an instrument panel (not shown) side to the mount bracket 102.
04a was fastened.

The mount bracket 102 has a substantially rectangular shape in plan view, and has bolt insertion holes 102a at four corners.
Are formed, and bolts 105 are fastened to the upper surface side of 101 using the bolt insertion holes 102a. Further, a brace mounting portion 102b formed to be bent upward and bulging is provided at an intermediate portion in the front-rear direction of the mount bracket 102,
Stud bolts 106 are integrally welded to the brace mounting portion 102b so as to protrude upward. Lower end portions 103a, 104a of instrument panel floor braces 103, 104 are fitted into these stud bolts 106, and nuts are attached to the stud bolts 106. The instrument panel floor braces 103 and 104 were fixed by fastening 107.

A transmission control cable 108 for connecting a change lever (not shown) disposed on the rear side of the mount bracket 102 and a tonsion transmission (not shown) disposed on the front side of the mount bracket 102 is connected to a transmission control cable 108 of the mount bracket 102. The lower surface side of the floor panel 101 corresponding to the lower side, that is, the outdoor side is arranged along the front-rear direction.

As an arrangement structure of this type of transmission control cable 108, see, for example,
There is one disclosed in Japanese Patent No. 9134.

[0006]

However, since an exhaust pipe is usually arranged on the lower surface side of the floor panel 101 along the front-rear direction, the transmission control cable 108 is deteriorated in durability due to heat radiation from the exhaust pipe side. There is a great risk of heat damage.

Therefore, when the transmission control cable 108 is arranged on the upper surface side of the floor panel 101, that is, on the indoor side, there is an advantage that the transmission control cable 108 is less susceptible to heat damage from the exhaust pipe side and the assembling work is easy. is there.

However, in the structure in which the floor panel 101 and the instrument panel floor braces 103 and 104 are fastened to each other by the mount bracket 102, if the transmission control cable 108 is disposed on the upper surface of the floor panel 101, the transmission control cable 108 Mount bracket 102
If the transmission control cable 108 is disposed above the mount bracket 102, the transmission control cable 108 is greatly bent at the position of the brace mounting portion 102b, which increases the operability of the change lever and accelerates the wear of the transmission control cable 108. Disadvantages occur.

In view of the above problems, the present invention provides a vehicle in which the transmission control cable can be disposed indoors while the operability of the change lever is ensured, and the rigidity of the mount bracket is improved. An object of the present invention is to provide a transmission control cable arrangement structure.

[0010]

A technical means for achieving the above object is that a lower end portion of an instrument panel floor brace is fastened to a mounting bracket attached to an upper surface of a floor panel, and is disposed on a rear side of the mounting bracket. In the transmission control cable arranging structure of the vehicle in which the transmission control cable is arranged between the change lever and the transmission arranged on the front side of the mount bracket,
At the center in the left-right direction of the mount bracket, there is provided a cable insertion concave portion which is formed to be bent upward and extends in the front-rear direction, and the transmission control cable is provided through a cable insertion passage surrounded by a floor panel and the cable insertion concave portion. The point is that it is arranged.

[0011]

According to the present invention, the transmission control cable is passed along the front and rear sides of the floor panel, that is, the indoor side, through the cable insertion passage surrounded by the cable insertion concave portion and the floor panel over the entire length of the mount bracket in the front and rear direction. By arranging, the transmission control cable can be effectively prevented from being greatly bent,
Good operability of the change lever can be secured.

Further, since the transmission control cable is disposed in a cable insertion path surrounded by the cable insertion concave portion and the floor panel, the movement of the transmission control cable is effectively restricted by the inner surface of the cable insertion concave portion and the upper surface of the floor panel. It is not necessary to provide a separate cable positioning clamp.

Further, the bent cable insertion concave portion functions as a bead, and the rigidity of the mount bracket is improved.
