Abstract

A work vehicle is disclosed that includes an elastic support mechanism for supporting an exhaust muffler. The elastic support mechanism includes a support platform member, an elastic cylindrical members and an bar-shaped member. The support platform member is supported by a rear-linking frame bar to adjust a position of the support platform member along one of lateral and longitudinal directions of the body frame. An elastic cylindrical member supported by one of the support platform member and the exhaust muffler. The elastic cylindrical member has an axis extending along the other of the lateral and longitudinal directions, and is supported at a single position, in a direction of the axis, of said one of the support platform member and the exhaust muffler. A bar-shaped member supported by the other of the support platform member and the exhaust muffler is fitted into the elastic cylindrical member to be supported by the elastic cylindrical member.

First claim

What is claimed is:

1. A work vehicle, comprising:
a body frame;
an engine;
an exhaust muffler associated with the engine;
a support structure provided in the body frame for supporting the engine; and
an elastic support mechanism interposed between the support structure and the exhaust muffler for supporting the exhaust muffler on the support structure, the elastic support mechanism including:
a support platform member supported by the support structure, the support platform member being configured to adjust a position of the support platform member along one of lateral and longitudinal directions of the body frame,
an elastic cylindrical member supported by one of the support platform member and the exhaust muffler, the elastic cylindrical member having an axis extending along the other of the lateral and longitudinal directions, and the elastic cylindrical member being supported at a single position, in a direction of said axis, of said one of the support platform member and the exhaust muffler, wherein a longitudinal axis of the elastic cylindrical member extends substantially parallel to a longitudinal axis of an adjusting member that is provided to permit adjustment of the position of the support platform member, and
a bar-shaped member supported by the other of the support platform member and the exhaust muffler, the bar-shaped member being fitted into the elastic cylindrical member to be supported by the elastic cylindrical member.

2. The work vehicle according to claim 1 , wherein
the elastic cylindrical member is supported by the support platform member, and
the bar-shaped member is supported by the exhaust muffler.

3. The work vehicle according to claim 1 , wherein
a pair of the elastic cylindrical members are arranged side by side in said one of the lateral and longitudinal directions, and
a pair of the bar-shaped members are inserted and fitted into the respective elastic cylindrical members in the same direction as each other.

4. The work vehicle according to claim 1 , further comprising:
a travel mechanism;
an exhaust pipe connecting the engine and the exhaust muffler; and
a transmission for transmitting power of the engine to the travel mechanism,
wherein the body frame includes a first body frame section and a second body frame section detachably attached to the first body frame section, the second body frame section supporting the engine, the exhaust pipe and the transmission, and
wherein the support structure forms the second body frame section.
