To curb an increase in back pressure in an exhaust pipe and to further reduce an impact on a passenger cabin.SOLUTION: A combustion type heater is arranged at a side section below a front passenger seat of a vehicle and supplies warm air from a front lower side of the passenger seat or a front lower side of a driver seat. An exhaust pipe structure of the combustion type heater has an exhaust pipe of a combustion type heater posteriorly extended along a side face below the passenger seat and an exhaust pipe outlet arranged in a direction toward the side face of the passenger seat between front and rear wheels. Because the exhaust pipe outlet is arranged between the front and rear wheels, a length of the exhaust pipe can be shortened compared to a case of arranging the same at a rear section of the vehicle and thereby curbing an increase in back pressure in the exhaust pipe. Additionally, arranging the exhaust pipe outlet so as to direct toward the side face of the passenger seat enables an impact of exhaust on a passenger cabin to be reduced.SELECTED DRAWING: Figure 1

    【課題】排気管の背圧が大きくなるのを抑制すると共に乗員室に影響をより小さくする。【解決手段】燃焼式ヒータは、車両の前方の助手席下方の側部に配置され、助手席前方下側や運転席前方下側から温風を供給する。燃焼式ヒータの排気管構造としては、焼式ヒータの排気管を助手席下方の側面に沿って後方に延出し、前輪と後輪の間で助手席側面方向に向けて排気管出口を配置する。前輪と後輪の間に排気管出口を配置するから、車両後部に排気管出口を配置するものに比して、排気管の長さを短くすることができ、排気管の背圧が大きくなるのを抑制することができる。また、助手席側面方向に向けて排気管出口を配置するから、排気の乗員室への影響をより小さくすることができる。【選択図】図1
