Further, as shown in FIG. 1, a shaft-like support member 81 extending in the vehicle width direction is attached to the bracket 8. The support member 81 is inserted into the inner cylinder 42 of the engine mount body 4.

なお、実際には、パワーユニット３と車体前部構造の間には、リアエンジンマウント１とは別に、フロントエンジンマウント、およびサイドエンジンマウントが介在している。   Actually, a front engine mount and a side engine mount are interposed between the power unit 3 and the vehicle body front structure in addition to the rear engine mount 1.

次に、作用について説明する。   Next, the operation will be described.

本実施の形態に係るエンジンマウント構造は、エンジンマウント本体４を構成している外筒４１の内周部と内筒４２の外周部の間に、弾性体としてのラバーマウント４３を介在させているため、従来のものと同様に、パワーユニット３の振動をボディへ伝わりにくくすることができる。   In the engine mount structure according to the present embodiment, a rubber mount 43 as an elastic body is interposed between the inner peripheral portion of the outer cylinder 41 and the outer peripheral portion of the inner cylinder 42 constituting the engine mount body 4. Therefore, the vibration of the power unit 3 can be made difficult to be transmitted to the body, as in the conventional case.

さらに、本実施の形態に係るエンジンマウント構造は、エンジンマウント本体４を構成する外筒４１の外周部に、車両前方側部材５、および車両後方側部材６の上端部を固定し、車両前後方向に延びる連結部材７の上部に、車両前方側部材５、および車両後方側部材６の下端部を固定し、サスペンションメンバ２に、連結部材７を介して車両前方側部材５、および車両後方側部材６を締結している。   Further, in the engine mount structure according to the present embodiment, the vehicle front side member 5 and the vehicle rear side member 6 are fixed to the outer peripheral portion of the outer cylinder 41 constituting the engine mount main body 4, and the vehicle front and rear direction is fixed. The lower ends of the vehicle front side member 5 and the vehicle rear side member 6 are fixed to the upper part of the connecting member 7 extending to the suspension member 2, and the vehicle front side member 5 and the vehicle rear side member are connected to the suspension member 2 via the connection member 7. 6 is concluded.

サスペンションメンバ２は、車両前方側部材５、車両後方側部材６、および連結部材７により補強されるため、この結果、サスペンションメンバ２の剛性が高くなって、車両の走行性や乗り心地を向上させることができる。   Since the suspension member 2 is reinforced by the vehicle front side member 5, the vehicle rear side member 6, and the connecting member 7, as a result, the rigidity of the suspension member 2 is increased and the running performance and riding comfort of the vehicle are improved. be able to.

車両前方側部材５、および車両後方側部材６の断面形状を、チャンネル材のように構成して、これら車両前方側部材５、および車両後方側部材６の剛性を高くすることや、連結部材７の中間部７３を、車両前方側部材５における車両前方側主支持部５１の車両後方側縁部、および車両後方側部材６における車両後方側主支持部６１の車両前方側縁部に溶接により固定することも、連結部材７の強度を増加させ、サスペンションメンバ２の剛性を高めることに寄与している。   The cross-sectional shape of the vehicle front side member 5 and the vehicle rear side member 6 is configured like a channel material so that the rigidity of the vehicle front side member 5 and the vehicle rear side member 6 is increased, or the connecting member 7 is used. Are fixed to the vehicle rear side edge portion of the vehicle front side main support portion 51 in the vehicle front side member 5 and the vehicle front side edge portion of the vehicle rear side main support portion 61 in the vehicle rear side member 6 by welding. This also contributes to increasing the strength of the connecting member 7 and increasing the rigidity of the suspension member 2.

また、連結部材７は、車両前方側部材５と車両後方側部材６の間で、上側に向けて凸状に湾曲するよう形成されているため、エンジンマウント本体４とサスペンションメンバ２の間にある図示されていないギヤボックス等の部材に、連結部材７が干渉することがない。   Further, since the connecting member 7 is formed between the vehicle front side member 5 and the vehicle rear side member 6 so as to be convexly curved upward, it is located between the engine mount body 4 and the suspension member 2. The connecting member 7 does not interfere with members such as a gear box (not shown).

なお、本実施の形態では、車両前方側部材５、および車両後方側部材６を、連結部材７を介してサスペンションメンバ２に締結しているが、車両前方側部材５、および車両後方側部材６を、直接、サスペンションメンバ２に締結するような構成としてもよい。   In the present embodiment, the vehicle front side member 5 and the vehicle rear side member 6 are fastened to the suspension member 2 via the connecting member 7, but the vehicle front side member 5 and the vehicle rear side member 6 are connected. May be directly fastened to the suspension member 2.
