Description

車両のリレー取付構造Vehicle relay mounting structure
　本発明は、リレースイッチをエンジンに取り付ける車両のリレー取付構造に関する。 The present invention relates to a vehicle relay mounting structure in which a relay switch is mounted on an engine.
　従来、アイドルストップ機構を備える車両において、アイドルストップ後のエンジン再始動を行うためのパワーリレーを有している。このパワーリレーは音振（作動音と振動）が大きいため、インシュレータを介して車体に取り付けられることが知られている。また、車体にエンジンマウントを介して支持されているエンジンのブロック側面に取り付けられることもある（例えば、特許文献１）。このようなエンジンが車両の前方かつ縦置きに設置される場合、前面衝突時にエンジンルームが潰れても、パワーリレーはエンジンの側面に取り付けられているので、パワーリレーが保護される。 Conventionally, a vehicle having an idle stop mechanism has a power relay for restarting the engine after the idle stop. This power relay is known to be attached to the vehicle body via an insulator because of its large sound vibration (operating sound and vibration). Moreover, it may attach to the block side surface of the engine currently supported by the vehicle body via the engine mount (for example, patent document 1). When such an engine is installed in front of the vehicle in a vertical position, even if the engine room is crushed at the time of a frontal collision, the power relay is protected because the power relay is attached to the side of the engine.

　しかしながら、従来の車両にあっては、パワーリレーがエンジンの側面に取り付けていたので、エンジンが車両の前方かつ横置きに設置される前輪駆動車等の場合、エンジンブロック側面が、車両前方側又は後方側を向くことになる。このため、前面衝突時にエンジンルームが潰れることにより、パワーリレーが損傷するおそれがある、という問題がある。 However, in the conventional vehicle, since the power relay is attached to the side surface of the engine, in the case of a front-wheel drive vehicle or the like in which the engine is installed in front and sideways of the vehicle, the engine block side surface is It will turn to the rear side. For this reason, there exists a problem that a power relay may be damaged when an engine room is crushed at the time of a frontal collision.
　本発明は、上記問題に着目してなされたもので、リレーの音振抑制とリレーの保護との両立を図ることができる車両のリレー取付構造を提供することを目的とする。 The present invention has been made paying attention to the above problem, and an object of the present invention is to provide a vehicle relay mounting structure capable of achieving both suppression of relay vibration and protection of the relay.
　上記目的を達成するため、本発明の車両のリレー取付構造は、エンジンルーム内に、エンジンと、バッテリと、バッテリから供給される電力により動作するアクチュエータと、バッテリとアクチュエータとの間にハーネスを介して接続されているリレースイッチと、を備え、エンジンはエンジンマウントインシュレータを介して車体に弾性支持されている。
この車両において、リレースイッチを、エンジンのロッカーカバーに取り付けてある。 In order to achieve the above object, a vehicle relay mounting structure according to the present invention includes an engine, a battery, an actuator operated by electric power supplied from the battery, and a harness between the battery and the actuator. The engine is elastically supported by the vehicle body via an engine mount insulator.
In this vehicle, a relay switch is attached to an engine rocker cover.
　よって、リレースイッチは、エンジンのロッカーカバーに取り付けられている。
即ち、リレースイッチはエンジンに取り付けられているので、リレースイッチもエンジンマウントインシュレータを介して、車体に弾性支持されていることになる。このため、リレースイッチの作動時の音振は、エンジンを介して、エンジンマウントインシュレータに伝搬する。これにより、リレースイッチの作動時の音振は、エンジンマウントインシュレータによって抑制される。
また、リレースイッチはエンジンに取り付けられているので、衝突時にエンジンルームが潰されても、エンジンは周辺部品よりも相対的に強度が高いから潰れにくく、リレースイッチが保護される。
この結果、リレースイッチの音振抑制とリレースイッチの保護との両立を図ることができる。 Therefore, the relay switch is attached to the engine rocker cover.
That is, since the relay switch is attached to the engine, the relay switch is also elastically supported by the vehicle body via the engine mount insulator. For this reason, sound vibration at the time of operation of the relay switch propagates to the engine mount insulator via the engine. Thereby, the sound vibration at the time of the action | operation of a relay switch is suppressed by an engine mount insulator.
In addition, since the relay switch is attached to the engine, even if the engine room is crushed at the time of a collision, the engine is relatively stronger than the surrounding parts and thus is not easily crushed, and the relay switch is protected.
As a result, it is possible to achieve both the suppression of the vibration of the relay switch and the protection of the relay switch.

　前記サイドメンバ３は、車両前方位置から車両後方位置まで延びる左右一対のフレーム部材により構成される車体メインフレームである。 The side member 3 is a vehicle body main frame composed of a pair of left and right frame members extending from the vehicle front position to the vehicle rear position.
　前記エンジンマウントインシュレータ４は、エンジン５の音振（振動と音）を抑制する弾性体（例えば、流体やラバー等）である。このエンジンマウントインシュレータ４は、図２に示すように、サイドメンバ３とエンジン５との間に配置されている。エンジンマウントインシュレータ４は、図２に示すように、エンジン５をサイドメンバ３に弾性支持している。 The engine mount insulator 4 is an elastic body (for example, fluid, rubber, etc.) that suppresses sound vibration (vibration and sound) of the engine 5. As shown in FIG. 2, the engine mount insulator 4 is disposed between the side member 3 and the engine 5. As shown in FIG. 2, the engine mount insulator 4 elastically supports the engine 5 on the side member 3.
　前記エンジン５は、図１～図３に示すように、エンジンルーム２内に横置きに配置されている。このエンジン５は、図４に示すように、ロッカーカバー５１とエンジンヘッド５２（シリンダヘッド）とシリンダブロック等から構成されている。前記ロッカーカバー５１は、図４に示すようにエンジン５の上部位置に配置されており、カムシャフトやロッカーアーム等を覆っている。このロッカーカバー５１には、図４に示すように、エンジンヘッド５２に取り付けてなる取付部５１ａが設けられている。この取付部５１ａに、ボルト５３を挿入し、このボルト５３を締め付けることにより、ロッカーカバー５１がエンジンヘッド５２に取り付けられる。前記エンジンヘッド５２は、ロッカーカバー５１とシリンダブロックとの間に配置されている。このエンジンヘッド５２には、インテークマニホールド６から供給される空気を取り入れる吸気ポート５２ａ等が形成されている。前記吸気ポート５２ａは、図４に示すように、車両１の前後方向の前方位置側に配置されている。 The engine 5 is arranged horizontally in the engine room 2 as shown in FIGS. As shown in FIG. 4, the engine 5 includes a rocker cover 51, an engine head 52 (cylinder head), a cylinder block, and the like. The rocker cover 51 is disposed at an upper position of the engine 5 as shown in FIG. 4 and covers a camshaft, a rocker arm, and the like. As shown in FIG. 4, the rocker cover 51 is provided with an attachment portion 51 a that is attached to the engine head 52. The rocker cover 51 is attached to the engine head 52 by inserting the bolt 53 into the attachment portion 51 a and tightening the bolt 53. The engine head 52 is disposed between the rocker cover 51 and the cylinder block. The engine head 52 is formed with an intake port 52a for taking in air supplied from the intake manifold 6. As shown in FIG. 4, the intake port 52 a is disposed on the front position side in the front-rear direction of the vehicle 1.
　前記インテークマニホールド６は、図１～図４に示すように、エンジン５の上部を覆う位置に配置されている。また、インテークマニホールド６は、吸気ポート５２ａに取り付けられている。このインテークマニホールド６は、樹脂からなり、サージタンク６１と一体に形成されている。インテークマニホールド６は、吸気系に配置されているエアダクト６２等と接続されている。このエアダクト６２から供給される空気が、サージタンク６２に溜められる。このサージタンク６２に溜められた空気が、インテークマニホールド６から吸気ポート５２ａへ供給される。 The intake manifold 6 is disposed at a position covering the upper part of the engine 5 as shown in FIGS. The intake manifold 6 is attached to the intake port 52a. The intake manifold 6 is made of resin and is formed integrally with the surge tank 61. The intake manifold 6 is connected to an air duct 62 and the like disposed in the intake system. Air supplied from the air duct 62 is stored in the surge tank 62. The air stored in the surge tank 62 is supplied from the intake manifold 6 to the intake port 52a.
　前記12Vバッテリ７は、車両電装品（例えば、スタータモータ８）の電源として用いられる二次電池であり、例えば、鉛バッテリが用いられる。この12Vバッテリ７は、車両左右（車幅）方向の左側位置（エンジン５の左側位置）に配置されている。 The 12V battery 7 is a secondary battery used as a power source for vehicle electrical components (for example, a starter motor 8), for example, a lead battery. The 12V battery 7 is disposed at a left side position (left side position of the engine 5) in the vehicle left-right (vehicle width) direction.
　前記スタータモータ８は、図２に示すように、エンジン５の側面に配置されており、12Vバッテリ７側に配置されている。このスタータモータ８は、エンジン５のクランクシャフトに設けられたエンジン始動用ギヤに噛み合うギヤを持ち、12Vバッテリ７を電源とし、エンジン始動時や再始動時にクランクシャフトを回転駆動するクランキングモータである。 As shown in FIG. 2, the starter motor 8 is arranged on the side surface of the engine 5 and is arranged on the 12V battery 7 side. The starter motor 8 is a cranking motor that has a gear that meshes with an engine start gear provided on a crankshaft of the engine 5, uses a 12V battery 7 as a power source, and rotationally drives the crankshaft when the engine is started or restarted. .
　ICRリレー９は、図１～図４に示すように、ロッカーカバー５１に取り付けられている。このICRリレー９は、図２示すように、12Vバッテリ７とスタータモータ８との間にハーネス１０を介して接続されている。即ち、ICRリレー９は、12Vバッテリ７の電力をスタータモータ８へ供給するリレーである。なお、図２に示すように、12Vバッテリ７とICRリレー９とを繋ぐハーネスを第１スタータハーネス１０ａとし、スタータモータ８とICRリレー９とを繋ぐハーネスを第２スタータハーネス１０ｂとする。これらのスタータハーネス１０ａ，１０ｂは、エンジン５始動時や再始動時の大電流に対応するように構成されている。また、これらのスタータハーネス１０ａ，１０ｂは、車両衝突時にスタータハーネス１０ａ，１０ｂが引っ張られ、このスタータハーネス１０ａ，１０ｂに過大なテンションが掛かると、スタータハーネス１０ａ，１０ｂが断線してしまう可能性があるので、通常、スタータハーネス１０ａ，１０ｂは余分な長さを持って、つまり弛みを持って設けられている。 The ICR relay 9 is attached to the rocker cover 51 as shown in FIGS. As shown in FIG. 2, the ICR relay 9 is connected between a 12V battery 7 and a starter motor 8 via a harness 10. That is, the ICR relay 9 is a relay that supplies the power of the 12V battery 7 to the starter motor 8. As shown in FIG. 2, the harness connecting the 12V battery 7 and the ICR relay 9 is referred to as a first starter harness 10a, and the harness connecting the starter motor 8 and the ICR relay 9 is referred to as a second starter harness 10b. These starter harnesses 10a and 10b are configured to cope with a large current when the engine 5 is started or restarted. In addition, when the starter harnesses 10a and 10b are pulled when the vehicle collides, and the starter harnesses 10a and 10b are excessively tensioned, the starter harnesses 10a and 10b may be disconnected. Therefore, the starter harnesses 10a and 10b are usually provided with an extra length, that is, with a slack.
　また、ICRリレー９には、図５と図６に示すように、抵抗体９ａ（ICR内部抵抗体）とリレー９ｂが並列に内蔵されている。ICRリレー９は、エンジン５の始動直後や再始動直後の過大電流（突入電流）を抑制し、12Vバッテリ７の長寿命化、スタータモータ８の瞬停（瞬時電圧低下、再起動）防止を担っている。例えば、車両１がアイドルストップ後のエンジン５再始動時、スタータモータ８が始動する。このエンジン５再始動初期（例えば、0msec～約200ｍsec）のとき、図５に示すように、リレー９ｂをオープンとし、12Vバッテリ７の電力は抵抗体９ａを介してスタータモータ８へ供給される（図５の矢印）。これにより、抵抗体９ａにて過大電流を抑制する。また、エンジン５始動初期（例えば、約200ｍsec～）では、図６に示すように、リレー９ｂをクローズとし、12Vバッテリ７の電力はリレー９ｂを介してスタータモータ８へ供給される（図６の矢印）。なお、図５と図６に示すように、12Vバッテリ７・スタータモータ８・ICRリレー９は、アースされている。 Also, as shown in FIGS. 5 and 6, the ICR relay 9 includes a resistor 9a (ICR internal resistor) and a relay 9b built in parallel. The ICR relay 9 suppresses an excessive current (rush current) immediately after the engine 5 is started or restarted, thereby extending the life of the 12V battery 7 and preventing the starter motor 8 from being momentarily stopped (instantaneous voltage drop or restart). ing. For example, the starter motor 8 is started when the engine 1 is restarted after the vehicle 1 is idle stopped. At the initial stage of restart of the engine 5 (for example, 0 msec to about 200 msec), as shown in FIG. 5, the relay 9b is opened and the power of the 12V battery 7 is supplied to the starter motor 8 via the resistor 9a ( Arrow in FIG. 5). Thereby, an excessive current is suppressed by the resistor 9a. Further, at the initial start of the engine 5 (for example, about 200 msec or more), as shown in FIG. 6, the relay 9b is closed and the power of the 12V battery 7 is supplied to the starter motor 8 via the relay 9b (FIG. 6). Arrow). As shown in FIGS. 5 and 6, the 12V battery 7, the starter motor 8, and the ICR relay 9 are grounded.

FIG. 8 is a schematic diagram of a vehicle relay mounting structure according to the first embodiment in a state where a harness is removed from an ICR relay.

　ICRリレー９は、図４に示すように、ロッカーカバー５１の上面５１ｂかつ角部５１ｃ近傍かつ取付部５１ａ近傍に、ブラケット９１を介して取り付けられている。即ち、エンジン５を車両１の上方から下方に向かって見たとき、図１～図４と図７～図８に示すように、ICRリレー９がエンジン５と重なり合う状態に配置されている。言い換えると、ICRリレー９は、エンジン５の外周よりも内側の範囲に配置されている。このICRリレー９は、図１～図３に示すように、インテークマニホールド６の車両前後方向の後方位置へ配置されている。また、ICRリレー９は、12Vバッテリ７側に配置されている。
  なお、ICRリレー９は、図７や図８に示すように、ブラケット９１にボルト９２とナット９３により取り付けられている。また、ICRリレー９の第１端子９ｃ（図８参照）は、図７に示すように、第１スタータハーネス１０ａと接続されている。ICRリレー９の第２端子９ｄ（図８参照）は、図７に示すように、第２スタータハーネス１０ｂと接続されている。ICRリレー９のアース９ｅは、図７に示すように、ブラケット９１に取り付けられている。 As shown in FIG. 4, the ICR relay 9 is attached to the upper surface 51 b of the rocker cover 51, in the vicinity of the corner portion 51 c and in the vicinity of the attachment portion 51 a via a bracket 91. That is, when the engine 5 is viewed from above the vehicle 1 downward, the ICR relay 9 is disposed so as to overlap the engine 5 as shown in FIGS. 1 to 4 and FIGS. 7 to 8. In other words, the ICR relay 9 is arranged in a range inside the outer periphery of the engine 5. As shown in FIGS. 1 to 3, the ICR relay 9 is disposed behind the intake manifold 6 in the vehicle longitudinal direction. The ICR relay 9 is disposed on the 12V battery 7 side.
The ICR relay 9 is attached to a bracket 91 with bolts 92 and nuts 93 as shown in FIGS. Moreover, the 1st terminal 9c (refer FIG. 8) of the ICR relay 9 is connected with the 1st starter harness 10a, as shown in FIG. As shown in FIG. 7, the second terminal 9d (see FIG. 8) of the ICR relay 9 is connected to the second starter harness 10b. The ground 9e of the ICR relay 9 is attached to a bracket 91 as shown in FIG.
　前記ブラケット９１は、図７や図８に示すように、２本のボルト９１ａにより、ロッカーカバー５１に取り付けられている。 The bracket 91 is attached to the rocker cover 51 by two bolts 91a as shown in FIGS.
　次に作用を説明する。
実施例１の車両のリレー取付構造における作用を、「アイドルストップ後の再始動時におけるICRリレー作動時の音振伝搬作用」と、「車両のリレー取付構造の特徴的作用」に分けて説明する。 Next, the operation will be described.
The operation of the vehicle relay mounting structure according to the first embodiment will be described by dividing it into “a sound vibration propagation operation when the ICR relay is activated at the time of restart after idling stop” and “characteristic operation of the vehicle relay mounting structure”. .
　［アイドルストップ後の再始動時におけるICRリレー作動時の音振伝搬作用］
  ICRリレー９が作動時に発する音振（ICRリレー９の音振）の伝搬について、図９を用いて説明する。図９は、実施例１の車両のリレー取付構造が適用されたFFアイドルストップ車両のエンジンルームの概略正面図を示し、ICRリレーが作動時に発する音振の伝搬経路を示している説明図である。 [Sound vibration propagation when ICR relay is activated after restart after idle stop]
Propagation of sound vibration generated when the ICR relay 9 operates (sound vibration of the ICR relay 9) will be described with reference to FIG. FIG. 9 is a schematic front view of the engine room of the FF idle stop vehicle to which the vehicle relay mounting structure of the first embodiment is applied, and is an explanatory diagram illustrating a propagation path of sound vibrations generated when the ICR relay is activated. .
　実施例１では、ICRリレー９がロッカーカバー５１に取り付けられていることにより、ICRリレー９から発せられる音振は、図９の矢印Ａで示すように、ブラケット９１からエンジン５（ロッカーカバー５１、エンジンヘッド５２）へ伝搬し、エンジン５の途中から図９の矢印Ｂと矢印Ｃのように分れて伝搬する。
  図９の矢印Ｂは、エンジン５の端から端へすなわち車両１の車幅方向中央側の端（フライホイール側）から車幅方向右側の端へ伝搬して、エンジン５からエンジンマウントインシュレータ４を介してサイドメンバ３へ伝搬する。そして、サイドメンバ３等から車室内へと伝搬する。
  また、図９の矢印Ｃは、エンジン５（エンジンヘッド５２、シリンダブロック、フライホイール）から変速機１００へ伝搬して、変速機１００からエンジンマウントインシュレータ４を介してサイドメンバ３へ伝搬する。そして、サイドメンバ３等から車室内へと伝搬する。 In the first embodiment, since the ICR relay 9 is attached to the rocker cover 51, sound vibrations emitted from the ICR relay 9 are transmitted from the bracket 91 to the engine 5 (the rocker cover 51, It propagates to the engine head 52) and propagates from the middle of the engine 5 as shown by arrows B and C in FIG.
The arrow B in FIG. 9 propagates from the end of the engine 5 to the end, that is, from the end of the vehicle 1 in the vehicle width direction (flywheel side) to the right end of the vehicle width direction. It propagates to the side member 3 via. And it propagates from the side member 3 etc. to the vehicle interior.
Further, an arrow C in FIG. 9 propagates from the engine 5 (engine head 52, cylinder block, flywheel) to the transmission 100, and propagates from the transmission 100 to the side member 3 via the engine mount insulator 4. And it propagates from the side member 3 etc. to the vehicle interior.
　このように、実施例１のICRリレー９からエンジンマウントインシュレータ４までの伝搬経路の長さによる音振の減衰と、エンジンマウントインシュレータ４の消音・制振効果によってICRリレー９の音振が抑制される。このため、実施例１では、ICRリレー９の作動時の音振は、車室内において緩和される。なお、実施例１の伝搬経路の長さは、例えばエンジンの側面にリレースイッチを設けた場合の伝搬経路の長さよりも長いため、音振の減衰効果は実施例１の方が大きくなる。
  加えて、ICRリレー９の音振は、エンジン５や変速機１００等の剛性が高い部品を通って、ICRリレー９からエンジンマウントインシュレータ４まで伝搬するので、その音振が増幅されることを抑制することができる。 As described above, the sound vibration of the ICR relay 9 is suppressed by the attenuation of the sound vibration due to the length of the propagation path from the ICR relay 9 to the engine mount insulator 4 of Example 1 and the silencing and damping effect of the engine mount insulator 4. The For this reason, in Example 1, the sound vibration at the time of the action | operation of the ICR relay 9 is relieved in a vehicle interior. In addition, since the length of the propagation path of Example 1 is longer than the length of the propagation path when a relay switch is provided on the side surface of the engine, for example, the attenuation effect of sound vibration is larger in Example 1.
In addition, the sound vibration of the ICR relay 9 propagates from the ICR relay 9 to the engine mount insulator 4 through highly rigid parts such as the engine 5 and the transmission 100, so that the sound vibration is suppressed from being amplified. can do.
　［車両のリレー取付構造の特徴的作用］
  例えば、アイドルストップ機構を備える車両において、アイドルストップ後のエンジン再始動を行うためのパワーリレーを有している。このパワーリレーは音振（作動音と振動）が大きいため、インシュレータを介して車体に取り付けられる。また、車体にエンジンマウントを介して支持されているエンジンのブロック側面に取り付けられることもある。このようなエンジンが車両の前方かつ縦置きに設置される場合、前面衝突時にエンジンルームが潰れても、パワーリレーはエンジンの側面に取り付けられているので、パワーリレーが保護される。 [Characteristic operation of vehicle relay mounting structure]
For example, a vehicle having an idle stop mechanism has a power relay for restarting the engine after the idle stop. Since this power relay has a large sound vibration (operation sound and vibration), it is attached to the vehicle body via an insulator. Moreover, it may be attached to the block side surface of the engine supported by the vehicle body via the engine mount. When such an engine is installed in front of the vehicle in a vertical position, even if the engine room is crushed at the time of a frontal collision, the power relay is protected because the power relay is attached to the side of the engine.
　しかし、パワーリレーがエンジンの側面に取り付けている車両では、エンジンが車両の前方かつ横置きに設置される前輪駆動車等の場合、エンジンブロック側面が、車両前方側又は後方側を向くことになる。このため、前面衝突時にエンジンルームが潰れることにより、パワーリレーが損傷するおそれがある。 However, in a vehicle in which the power relay is attached to the side surface of the engine, the engine block side surface faces the front side or the rear side of the vehicle when the engine is a front-wheel drive vehicle or the like installed in front and sideways of the vehicle. . For this reason, there is a possibility that the power relay may be damaged by collapsing the engine room at the time of a frontal collision.
　これに対し、実施例１では、ICRリレー９を、エンジン５のロッカーカバー５１に取り付けてある構成とした（図１～図４と図７～図９）。
即ち、ICRリレー９はエンジン５に取り付けられているので、ICRリレー９もエンジンマウントインシュレータ４を介して、サイドメンバ３に弾性支持されていることになる。このため、ICRリレー９の作動時の音振は、エンジン５を介して、エンジンマウントインシュレータ４に伝搬する。これにより、ICRリレー９の作動時の音振は、エンジンマウントインシュレータ４によって抑制される。
また、ICRリレー９はロッカーカバー５１に取り付けられているので、衝突時にエンジンルーム２が潰されても、エンジン５は周辺部品よりも相対的に強度が高いから潰れにくく、ICRリレー９が保護される。
この結果、ICRリレー９の音振抑制とICRリレー９の保護との両立が図られる。 In contrast, in the first embodiment, the ICR relay 9 is configured to be attached to the rocker cover 51 of the engine 5 (FIGS. 1 to 4 and FIGS. 7 to 9).
That is, since the ICR relay 9 is attached to the engine 5, the ICR relay 9 is also elastically supported by the side member 3 via the engine mount insulator 4. For this reason, sound vibration when the ICR relay 9 is activated propagates to the engine mount insulator 4 through the engine 5. Thereby, the sound vibration at the time of the operation of the ICR relay 9 is suppressed by the engine mount insulator 4.
In addition, since the ICR relay 9 is attached to the rocker cover 51, even if the engine room 2 is crushed at the time of a collision, the engine 5 is relatively harder than the surrounding parts, so that the ICR relay 9 is protected. The
As a result, both the vibration suppression of the ICR relay 9 and the protection of the ICR relay 9 can be achieved.
　加えて、エンジン５もICRリレー９もエンジンマウントインシュレータ４を介して、サイドメンバ３に弾性支持されているので、エンジンマウントインシュレータ４を共通化することができる。このため、リレースイッチを車体に取り付けるための高価なインシュレータが不要となる。
従って、ICRリレー９をロッカーカバー５１に取り付けることにより、部品点数が削減されると共に、コストが低減される。 In addition, since both the engine 5 and the ICR relay 9 are elastically supported by the side member 3 via the engine mount insulator 4, the engine mount insulator 4 can be shared. For this reason, an expensive insulator for attaching the relay switch to the vehicle body becomes unnecessary.
Therefore, by attaching the ICR relay 9 to the rocker cover 51, the number of parts is reduced and the cost is reduced.
　実施例１では、ICRリレー９を、ロッカーカバー５１の角部５１ｃ近傍に取り付けてある構成とした（図４）。
即ち、ICRリレー９は、ロッカーカバー５１の中でも相対的に剛性が高い角部５１ｃの近傍に取り付けられているので、ICRリレー９の作動時の音振が伝搬時に増幅されにくい。
従って、ICRリレー９の作動時の音振がより抑制される。 In the first embodiment, the ICR relay 9 is configured in the vicinity of the corner 51c of the rocker cover 51 (FIG. 4).
That is, since the ICR relay 9 is attached in the vicinity of the corner portion 51c having a relatively high rigidity in the rocker cover 51, the sound vibration during the operation of the ICR relay 9 is not easily amplified during propagation.
Therefore, the sound vibration during the operation of the ICR relay 9 is further suppressed.
　実施例１では、ICRリレー９を、ロッカーカバー５１をエンジン５のエンジンヘッド５２に取り付けてなる取付部５１ａ近傍に取り付けてある構成とした（図４）。
即ち、取付部５１ａにより、ロッカーカバー５１はエンジンヘッド５２に固定されている。また、ICRリレー９は、その取付部５１ａ近傍に取り付けられている。このため、ICRリレー９の作動時の音振が伝搬時に増幅されにくい。
従って、ICRリレー９の作動時の音振がより一層抑制される。 In the first embodiment, the ICR relay 9 is configured to be mounted in the vicinity of the mounting portion 51a formed by mounting the rocker cover 51 on the engine head 52 of the engine 5 (FIG. 4).
That is, the rocker cover 51 is fixed to the engine head 52 by the attachment portion 51a. The ICR relay 9 is attached in the vicinity of the attachment portion 51a. For this reason, the sound vibration during operation of the ICR relay 9 is difficult to be amplified during propagation.
Therefore, the sound vibration during the operation of the ICR relay 9 is further suppressed.
　実施例１では、ICRリレー９を、ロッカーカバー５１の上面５１ｂに取り付けてある構成とした（図１～図４と図７～図８）。
即ち、ICRリレー９は、ロッカーカバー５１の上面５１ｂに取り付けられているので、衝突時にエンジンルームが潰されても、エンジン５が先あたり部品となると共に、エンジンは周辺部品よりも相対的に強度が高いから潰れにくく、ICRリレー９が保護される。
従って、エンジン５を縦置きに設置しても横置きに設置しても、衝突時のエンジンルーム２圧壊によるICRリレー９の損傷が抑制される。 In Example 1, the ICR relay 9 is configured to be attached to the upper surface 51b of the rocker cover 51 (FIGS. 1 to 4 and FIGS. 7 to 8).
That is, since the ICR relay 9 is attached to the upper surface 51b of the rocker cover 51, even if the engine room is crushed at the time of a collision, the engine 5 becomes the first component and the engine is relatively stronger than the peripheral components. Since it is high, it is difficult to be crushed and the ICR relay 9 is protected.
Therefore, whether the engine 5 is installed vertically or horizontally, damage to the ICR relay 9 due to the collapse of the engine room 2 at the time of collision is suppressed.
　加えて、車両１への衝突が、前面衝突でも前面オフセット衝突でも側面衝突であっても、ICRリレー９はロッカーカバー５１の上面５１ｂに取り付けられているので、上述したとおり、衝突時のエンジンルーム２圧壊によるICRリレー９の損傷が抑制される。
  また、衝突時、ICRリレー９がエンジン５の先あたりにより保護されるので、従来必要であったリレースイッチを強固に保護するプロテクタが不要となる。従って、ICRリレー９をロッカーカバー５１に取り付けることにより、部品点数が削減されると共に、コストが低減される。 In addition, whether the collision with the vehicle 1 is a frontal collision, a frontal offset collision or a side collision, the ICR relay 9 is attached to the upper surface 51b of the rocker cover 51. Damage to the ICR relay 9 due to two collapses is suppressed.
Further, since the ICR relay 9 is protected by the tip of the engine 5 at the time of a collision, a protector that strongly protects the relay switch that has been conventionally required becomes unnecessary. Therefore, by attaching the ICR relay 9 to the rocker cover 51, the number of parts is reduced and the cost is reduced.
　実施例１では、ICRリレー９を、樹脂製のインテークマニホールド６の車両前後方向の後方位置に配置してある構成とした（図１～図３）。
例えば、前面衝突時のエンジンルームの潰れによって、リレースイッチの車両前後方向の前方位置に配置される部品がリレースイッチの端子に接触すると、短絡が発生するおそれがある。
これに対し、実施例１では、ICRリレー９が、樹脂製のインテークマニホールド６の車両前後方向の後方位置に配置されている。
即ち、前面衝突時にエンジンルーム２が潰され、ICRリレー９よりも車両前後方向の前方位置に配置された部品が、ICRリレー９の端子（第１端子９ｃ若しくは第２端子９ｄ、又は両方の端子９ｃ，９ｄ）に接触することがあっても、その部品は樹脂製のインテークマニホールド６である。
従って、ICRリレー９の端子９ｃ，９ｄと樹脂製のインテークマニホールド６との接触による短絡の発生が抑制される。 In the first embodiment, the ICR relay 9 is arranged at the rear position in the vehicle front-rear direction of the resin intake manifold 6 (FIGS. 1 to 3).
For example, there is a possibility that a short circuit may occur if a component arranged in a forward position in the vehicle front-rear direction of the relay switch comes into contact with the terminal of the relay switch due to the collapse of the engine room at the time of a frontal collision.
On the other hand, in the first embodiment, the ICR relay 9 is disposed at the rear position in the vehicle front-rear direction of the resin intake manifold 6.
That is, the engine room 2 is crushed at the time of a frontal collision, and the parts arranged at a position ahead of the ICR relay 9 in the vehicle front-rear direction are the terminals of the ICR relay 9 (the first terminal 9c or the second terminal 9d, or both terminals). 9c, 9d), the part is a resin intake manifold 6.
Accordingly, occurrence of a short circuit due to contact between the terminals 9c and 9d of the ICR relay 9 and the resin intake manifold 6 is suppressed.
　実施例１では、エンジン５の12Vバッテリ７側に、スタータモータ８とICRリレー９とを配置してある構成とした（図２）。
即ち、12Vバッテリ７の近接位置に、スタータモータ８とICRリレー９とが配置される。
このため、その他の位置にスタータモータ８とICRリレー９とを配置する場合に比べて、12Vバッテリ７からICRリレー９までの第１スタータハーネス１０ａの長さと、ICRリレー９からスタータモータ８までの第２スタータハーネス１０ｂの長さとを短くすることができる。これにより、大電流に対応した太いハーネス１０であっても、電圧降下や電流低下が抑制される。
従って、12Vバッテリ７の近接位置にスタータモータ８とICRリレー９とが配置されることにより、電圧降下や電流低下が抑制される。 In the first embodiment, the starter motor 8 and the ICR relay 9 are arranged on the 12V battery 7 side of the engine 5 (FIG. 2).
That is, the starter motor 8 and the ICR relay 9 are disposed in the proximity of the 12V battery 7.
For this reason, compared with the case where the starter motor 8 and the ICR relay 9 are arranged at other positions, the length of the first starter harness 10a from the 12V battery 7 to the ICR relay 9 and the distance from the ICR relay 9 to the starter motor 8 are increased. The length of the second starter harness 10b can be shortened. Thereby, even if it is the thick harness 10 corresponding to a large current, a voltage drop and a current fall are suppressed.
Therefore, by arranging the starter motor 8 and the ICR relay 9 in the proximity position of the 12V battery 7, the voltage drop and the current drop are suppressed.
　加えて、スタータハーネス１０ａ，１０ｂの長さを短くすることができるので、その他の位置にスタータモータ８とICRリレー９とを配置する場合に比べて、衝突時、エンジン５の周辺部品の損傷等によって受けるテンションが低減される。このため、12Vバッテリ７とスタータモータ８とのそれぞれとICRリレー９を接続するハーネス断線の危険性が低下される。 In addition, since the length of the starter harnesses 10a and 10b can be shortened, compared to the case where the starter motor 8 and the ICR relay 9 are arranged at other positions, damage to peripheral parts of the engine 5 at the time of a collision, etc. The tension received by is reduced. For this reason, the danger of the harness disconnection which connects each of the 12V battery 7 and the starter motor 8, and the ICR relay 9 is reduced.

However, the relay switch is not limited to such an ICR relay 9, but may be a power relay, or a winch relay attached to the front end of the vehicle front-rear direction such as a pickup truck or a four-wheel drive (4WD) vehicle.
