<p>A pipe joint structure for an exhaust gas treatment device for an industrial vehicle that can absorb an external force and that can facilitate a fine adjustment of a gap formed at the pipe joint part for introducing the outside air into the pipe joint part. A diesel particulate filter (or an exhaust gas treatment device) 1 is provided with an exhaust pipe 5. A tapered distal end portion 5a of the exhaust pipe 5 is inserted into an opening portion 4a of the tail pipe 4 and a gap is formed of a tapered cross sectional shape between the distal end portion 5a of the exhaust pipe 5 and the opening portion 4a of the tail pipe 4. The exhaust pipe 5 has first bracket members 11, 11' and the tail pipe 4 has a second bracket member 12. Attachment bolts 13, 13' are inserted through the first bracket members 11, 11' and the second bracket member 12. Coil springs 15, 15' are fitted around the outer peripheries of the attachment bolts 13, 13' between the first bracket members 11, 11' and the second bracket member 12. The distal end portion 5a of the exhaust pipe 5 is elastically supported relative to the opening portion 4a of the tail pipe 4 in the longitudinal direction of the pipe.</p> |
