Abstract

A steering device includes: a steering handle; an upper shaft to which the steering handle is connected; a lower shaft that is disposed below the upper shaft; a universal joint that connects the upper shaft with the lower shaft; a column tube that covers an outer periphery of the upper shaft; and a parking brake release lever. The column tube has a lever backing bracket that supports the parking brake release lever swingably around an axis orthogonal to an axial direction of the upper shaft, and the parking brake release lever is disposed under the column tube.

First claim

What is claimed is:

1. A steering device comprising:
a steering handle;
an upper shaft to which the steering handle is connected;
a lower shaft that is disposed below the upper shaft;
a universal joint that connects the upper shaft with the lower shaft;
a column tube that covers an outer periphery of the upper shaft;
a parking brake release lever;
a cable that is connected to a parking brake device;
a cable holding member that holds the cable; and
a link mechanism that links the parking brake release lever with the cable holding member,
wherein the column tube has a lever backing bracket that supports the parking brake release lever swingably around a horizontal axis orthogonal to an axial direction of the upper shaft, and the parking brake release lever is disposed under the column tube, and
wherein the column tube has a cable backing bracket that supports the cable holding member swingably around an axis parallel to the horizontal axis, and the cable holding member is disposed on a side of the column tube.

2. The steering device according to claim 1 , wherein the link mechanism has a configuration in which a swing angle of the cable holding member is larger than a swing angle of the parking brake release lever.

3. The steering device according to claim 1 , further comprising:
a column cover that covers the column tube,
wherein the parking brake release lever has a metal main lever member and a resin exterior member that covers the main lever member, and
wherein the column cover and the exterior member house the link mechanism and the cable holding member.

4. A cargo handling vehicle comprising:
a main vehicle body;
a parking brake device that inhibits traveling of the main vehicle body;
a steering handle;
an upper shaft to which the steering handle is connected;
a lower shaft that is disposed below the upper shaft;
a universal joint that connects the upper shaft with the lower shaft;
a column tube that covers an outer periphery of the upper shaft;
a parking brake release lever;
a cable that is connected to the parking brake device;
a cable holding member that holds the cable; and
a link mechanism that links the parking brake release lever with the cable holding member,
wherein the column tube has a lever backing bracket that supports the parking brake release lever swingably around a horizontal axis orthogonal to an axial direction of the upper shaft, and the parking brake release lever is disposed under the column tube, and
wherein the column tube has a cable backing bracket that supports the cable holding member swingably around an axis parallel to the horizontal axis, and the cable holding member is disposed on a side of the column tube.

5. The cargo handling vehicle according to claim 4 , wherein the link mechanism has a configuration in which a swing angle of the cable holding member is larger than a swing angle of the parking brake release lever.

6. The cargo handling vehicle according to claim 4 , further comprising:
a column cover that covers the column tube,
wherein the parking brake release lever has a metal main lever member and a resin exterior member that covers the main lever member, and
wherein the column cover and the exterior member house the link mechanism and the cable holding member.

7. The cargo handling vehicle according to claim 4 , further comprising:
a parking brake pedal that operates the parking brake device,
wherein the parking brake device in a state of permitting the traveling of the main vehicle body starts to inhibit the traveling of the main vehicle body by an operation of the parking brake pedal, and
wherein the parking brake device in a state of inhibiting the traveling of the main vehicle body cancels the inhibiting of the traveling of the main vehicle body by simultaneous operations of both the parking brake release lever and the parking brake pedal.
