Description
以下の説明では、ユーティリティビークルの車体1に関し、図1に示される矢印Fの方向を「車体前方」、矢印Bの方向を「車体後方」、紙面表側の方向を「車体右方」、紙面裏側の方向を「車体左方」とする。
原動部10は、図2,3に示されるように、エンジン11、エンジン用の排気マフラー12、エンジン11の動力が入力され、入力された動力を前車輪2及び後車輪3に向けて出力する走行ミッション9などを備えている。
エンジン11で発生したブローバイガスがブローバイガス還流路21によって吸気路16に還流され、吸気路16によって燃焼室14に還流されて燃焼室14で燃焼される。
接続管22は、図2に示されるように、エンジン11の排気部11cから前方に延びるエンジン側前後向き部22a、排気マフラー12の吸気部12aから前方に延びるマフラー側前後向き部22b、マフラー側前後向き部22bの前端部とエンジン側前後向き部22aの前端部とを接続する横向き部22cを備えている。
これにより、連結ボルト35の締め込みストロークが設定以上にならないように締込み規制部材36によって規制され、防振材34が弾性(緩衝機能)を損なうまで締め付けられることを防止される。
(1)上記した実施形態では、第2の遮熱カバー27の前後向き車体フレーム13への支持に防振材が採用されていない例を示した、防振材を採用して実施してもよい。
