Abstract

The instrument panel reinforcement pipe extends in a width direction of a vehicle, and is formed in a circular tubular shape to support a steering column placed in a front-and-rear direction of the vehicle. The cowl-to brace extends in the front-and-rear direction of the vehicle, has a front end fixed on a cowl panel placed in a farther front side of the vehicle than the instrument panel reinforcement pipe, and includes a joint portion to be joined with the instrument panel reinforcement pipe, between the front end and a rear end. The floor brace extends in an up-and-down direction of the vehicle, and has a lower end fixed on a floor tunnel and an upper end fixed to the rear end of the cowl-to brace. The joint portion of the cowl-to brace is formed in a ring shape to be fitted and inserted into the instrument panel reinforcement pipe.

Claims

1. A steering support structure comprising:

a circular tubular instrument panel reinforcement pipe that extends in a width direction of a vehicle and that supports a steering column placed in a front-and-rear direction of the vehicle;

a cowl-to brace that extends in the front-and-rear direction of the vehicle, that has a front end fixed to a cowl panel placed in a farther front side of the vehicle than the instrument panel reinforcement pipe, and that comprises a joint portion to be joined with the instrument panel reinforcement pipe between the front end and a rear end; and

a floor brace that extends in an up-and-down direction of the vehicle, and that has a lower end fixed on a floor tunnel and an upper end fixed to the rear end of the cowl-to brace, wherein

the joint portion of the cowl-to brace is formed in a ring shape to be fitted and inserted into the instrument panel reinforcement pipe, and is joined over the entire circumference of the instrument panel reinforcement pipe.

2. The steering support structure according to claim 1, wherein

the floor brace comprises a D-seat floor brace placed on a side of a driver seat, and

an upper end of the D-seat floor brace is fixed to the rear end of the cowl-to brace.

3. A steering support structure comprising:

a circular tubular instrument panel reinforcement pipe that extends in a width direction of a vehicle and that supports a steering column placed in a front-and-rear direction of the vehicle;

a floor brace that extends in an up-and-down direction of the vehicle, that has a lower end fixed on a floor tunnel, and that comprises a joint portion to be joined with the instrument panel reinforcement pipe, between the lower end and an upper end; and

a cowl-to brace that extends in the front-and-rear direction of the vehicle, and that has a front end fixed on a cowl panel placed in a farther front side of the vehicle than the instrument panel reinforcement pipe, and a rear end fixed to the upper end of the floor brace, wherein

the joint portion of the floor brace is formed in a ring shape to be fitted and inserted into the instrument panel reinforcement pipe, and is joined over the entire circumference of the instrument panel reinforcement pipe.

4. The steering support structure according to claim 3, wherein

the floor brace comprises a D-seat floor brace placed on a side of a driver seat, and
