Description
この発明は、エンジンのシリンダヘッドに固定されるシリンダヘッドカバーに関するものである。 The present invention relates to a cylinder head cover fixed to an engine cylinder head.
シリンダヘッドに固定されるシリンダヘッドカバーには、意匠カバーが取り付けられることがある（例えば、特許文献１）。意匠カバーはシリンダヘッドカバー上に取り付けられるイグニッションコイルなどの部品を覆い隠し、エンジンの見栄えを向上させる。 A design cover may be attached to the cylinder head cover fixed to the cylinder head (for example, Patent Document 1). The design cover covers and conceals parts such as the ignition coil mounted on the cylinder head cover to improve the appearance of the engine.
ところで、意匠カバーはシリンダヘッドカバー上に取り付けられた部品を覆い隠すようにシリンダヘッドカバーの広い範囲を覆うものが一般的である。しかし、その重量やコストを考慮すると、仕様によっては、シリンダヘッドカバーに取り付けられた部品に接続されるワイヤーハーネスの収容部など、機能上必要な一部分のみを覆う小型の収容部カバーを採用することも考えられる。 By the way, the design cover generally covers a wide range of the cylinder head cover so as to conceal parts mounted on the cylinder head cover. However, considering its weight and cost, depending on the specifications, it is possible to adopt a small housing cover that covers only a part that is functionally necessary, such as a housing portion of a wire harness connected to a component attached to the cylinder head cover. Conceivable.
このとき、意匠カバーを取り付ける仕様のエンジンと収容部カバーを取り付ける仕様のエンジンとでシリンダヘッドカバーを使い分けるようにすることが考えられる。しかし、この場合には意匠カバーを取り付けるエンジンに使用するシリンダヘッドカバーと、収容部カバーを取り付けるエンジンに使用するシリンダヘッドカバーとを双方準備しなければならなくなる。 At this time, it is conceivable to use the cylinder head cover separately for an engine with a specification for attaching the design cover and an engine with a specification for attaching the housing cover. However, in this case, it is necessary to prepare both a cylinder head cover used for the engine to which the design cover is attached and a cylinder head cover to be used for the engine to which the housing portion cover is attached.
これに対して、シリンダヘッドカバーを１種類に統一し、意匠カバーを取り付けるための取付ボスに加えて、収容部カバーを取り付けるための取付ボスを設けることも考えられる。この場合には、いずれのカバーも取り付け可能になるものの、意匠カバーを取り付けた際には収容部カバーを取り付けるための取付ボスが無駄になり、収容部カバーを取り付けた際には意匠カバーを取り付けるための取付ボスが無駄になる。すなわち、使用されることのない無駄な取付ボスをたくさん設けることになってしまう。 On the other hand, it is also conceivable to unify the cylinder head cover into one type and provide an attachment boss for attaching the accommodating portion cover in addition to the attachment boss for attaching the design cover. In this case, although any cover can be attached, when the design cover is attached, the mounting boss for attaching the housing portion cover is wasted, and when the housing portion cover is attached, the design cover is attached. Mounting bosses are wasted. That is, a lot of useless mounting bosses that are not used are provided.
この発明は、上記実情に鑑みてなされたものであり、その目的は、無駄な取付ボスの増加を抑制しつつ、意匠カバーと収容部カバーのいずれもが取り付け可能なシリンダヘッドカバーを提供することにある。 The present invention has been made in view of the above circumstances, and an object thereof is to provide a cylinder head cover to which both a design cover and a housing portion cover can be attached while suppressing an increase in useless mounting bosses. is there.
以下、上記課題を解決するための手段及びその作用効果について記載する。
上記課題を解決するためのシリンダヘッドカバーは、部品を取り付ける部品取付部と、前記部品とは別の部品を収容する収容部と、前記収容部の少なくとも一部を覆う収容部カバーの固定に使用される取付ボスと、前記収容部の少なくとも一部に加えて前記部品取付部の少なくとも一部を覆う意匠カバーの固定に使用される複数の取付ボスと、を備え、前記意匠カバーの固定に使用される取付ボスのうち、少なくとも１つの取付ボスが前記収容部カバーの固定に使用される取付ボスを兼ねていることをその要旨とする。
Hereinafter, means for solving the above-described problems and the effects thereof will be described.
A cylinder head cover for solving the above problems is used for fixing a component mounting portion for mounting a component, a storage portion for storing a component different from the component, and a storage portion cover for covering at least a part of the storage portion. And a plurality of mounting bosses used for fixing a design cover covering at least a part of the component mounting part in addition to at least a part of the housing part, and used for fixing the design cover. Among the mounting bosses, at least one mounting boss also serves as a mounting boss used for fixing the housing portion cover.
上記構成によれば、意匠カバーの固定に使用される取付ボスの一部が収容部カバーの固定に使用される取付ボスと共通化されているため、意匠カバーの固定に使用される取付ボスと収容部カバーの固定に使用される取付ボスとを全く別々に設ける場合と比較して無駄な取付ボスの増加を抑制することができる。したがって、無駄な取付ボスの増加を抑制しつつ、意匠カバーと収容部カバーのいずれもが取り付け可能なシリンダヘッドカバーにすることができる。 According to the above configuration, since a part of the mounting boss used for fixing the design cover is shared with the mounting boss used for fixing the housing cover, the mounting boss used for fixing the design cover and An increase in useless mounting bosses can be suppressed as compared to a case where mounting bosses used for fixing the housing cover are provided completely separately. Therefore, it is possible to provide a cylinder head cover to which both the design cover and the housing portion cover can be attached while suppressing an increase in useless attachment bosses.
上記シリンダヘッドカバーにおいて、前記意匠カバーの固定に使用される取付ボスは、前記収容部と前記部品取付部の双方を挟む位置に対になって配設された外側取付ボスを含み、前記収容部カバーの固定に使用される取付ボスは、前記収容部と前記部品取付部との間に配設された内側取付ボスを含み、前記外側取付ボスのうち、前記内側取付ボスに対して前記収容部を挟んで位置する前記外側取付ボスが前記収容部カバーの固定に使用される取付ボスを兼ねていることをその要旨とする。 In the cylinder head cover, the mounting boss used for fixing the design cover includes an outer mounting boss disposed in a position sandwiching both the housing portion and the component mounting portion, and the housing portion cover. The mounting boss used for fixing includes an inner mounting boss disposed between the housing portion and the component mounting portion, and among the outer mounting bosses, the housing portion is disposed with respect to the inner mounting boss. The gist of the invention is that the outer mounting boss located between the two also serves as the mounting boss used for fixing the housing cover.
上記構成によれば、外側取付ボスは収容部と部品取付部の双方を挟む位置に対になって配設されている。そのため、外側取付ボスを使用することにより、収容部と部品取付部の双方を覆う意匠カバーを固定することができる。また、内側取付ボスは収容部と部品取付部との間に配設されているため、この内側取付ボスと、該内側取付ボスに対して収容部を挟んで位置する外側取付ボスとを使用することにより、部品取付部を覆わずに収容部を覆う収容部カバーを取り付けることができる。すなわち、上記構成によれば、外側取付ボスの一部に意匠カバーを固定する取付ボスとしての機能に加え、収容部カバーを固定する取付ボスとしての機能を具備させ、取付ボスの一部を共通化することができる。 According to the above configuration, the outer mounting bosses are arranged in pairs at positions sandwiching both the housing portion and the component mounting portion. Therefore, by using the outer mounting boss, the design cover that covers both the housing portion and the component mounting portion can be fixed. Further, since the inner mounting boss is disposed between the housing portion and the component mounting portion, the inner mounting boss and the outer mounting boss positioned with the housing portion interposed between the inner mounting boss and the inner mounting boss are used. Thereby, the accommodating part cover which covers an accommodating part, without covering a component attaching part can be attached. That is, according to the above configuration, in addition to the function as the mounting boss for fixing the design cover to a part of the outer mounting boss, the function as the mounting boss for fixing the housing cover is provided, and a part of the mounting boss is shared. Can be
上記シリンダヘッドカバーにおいて、前記外側取付ボスは、前記収容部の長手方向に離間させて複数設けられ、前記内側取付ボスは、前記長手方向において、離間させて設けられた前記外側取付ボスの間に配設されているのが好ましい。 In the cylinder head cover, a plurality of the outer mounting bosses are provided apart from each other in the longitudinal direction of the housing portion, and the inner mounting bosses are arranged between the outer mounting bosses provided apart from each other in the longitudinal direction. It is preferable to be provided.
上記構成によれば、収容部の長手方向に離間させて設けられた複数の外側取付ボスのうちの２つと、収容部を挟んで反対側に位置する１つの内側取付ボスとの少なくとも３点で収容部カバーを固定することができるため、少ない取付ボスで効果的に収容部カバーを固定することができる。 According to the above configuration, at least three points of two of the plurality of outer mounting bosses provided apart from each other in the longitudinal direction of the housing portion and one inner mounting boss located on the opposite side across the housing portion. Since the accommodating portion cover can be fixed, the accommodating portion cover can be effectively fixed with a small number of mounting bosses.
上記シリンダヘッドカバーにおいて、前記内側取付ボスの高さが前記外側取付ボスの高さよりも低いことが好ましい。
部品取付部と収容部との間に配設される内側取付ボスの高さが外側取付ボスの高さよりも高い場合には、部品取付部と収容部との双方を覆う意匠カバーを取り付ける際に内側取付ボスが邪魔になる。これに対して上記構成では、内側取付ボスの高さが、外側取付ボスの高さよりも低いため、意匠カバーを取り付ける際に内側取付ボスが邪魔になりにくい。
In the cylinder head cover, it is preferable that a height of the inner mounting boss is lower than a height of the outer mounting boss.
When the height of the inner mounting boss disposed between the component mounting portion and the housing portion is higher than the height of the outer mounting boss, when attaching the design cover that covers both the component mounting portion and the housing portion The inner mounting boss gets in the way. On the other hand, in the said structure, since the height of an inner side attachment boss is lower than the height of an outer side attachment boss, when attaching a design cover, an inner side attachment boss does not become obstructive.
上記シリンダヘッドカバーにおいて、前記取付ボスが、いずれも同じ形状の係合部を有しているのが好ましい。
上記構成によれば、シリンダヘッドカバーの構成を簡素化することができる。
In the cylinder head cover, it is preferable that each of the mounting bosses has an engaging portion having the same shape.
According to the above configuration, the configuration of the cylinder head cover can be simplified.
以下、上記課題を解決するシリンダヘッドカバーの一実施形態について、図１及び図２を参照して説明する。

また、ヘッドカバー本体１１０の外面側には、シリンダヘッドカバー１００に選択的に取り付けられるカバー４００，５００の固定に使用される複数の取付ボス１２０（１２０ａ，１２０ｂ，１２０ｃ）が設けられている。複数の取付ボス１２０には、短手方向Ｘにおいて収容部１１２と部品取付部１１１の双方を挟む位置に対になって配設された外側取付ボス１２０ａ，１２０ｂと、短手方向Ｘにおいて収容部１１２と部品取付部１１１との間に配設された内側取付ボス１２０ｃとが含まれている。 A plurality of mounting bosses 120 (120a, 120b, 120c) used for fixing covers 400, 500 that are selectively mounted on the cylinder head cover 100 are provided on the outer surface side of the head cover main body 110. The plurality of mounting bosses 120 include outer mounting bosses 120a and 120b disposed in pairs in positions in which both the housing portion 112 and the component mounting portion 111 are sandwiched in the short direction X, and the housing portion in the short direction X. An inner mounting boss 120c disposed between 112 and the component mounting portion 111 is included.
短手方向Ｘにおいて、内側取付ボス１２０ｃは対になって配設された外側取付ボス１２０ａ，１２０ｂの間に位置する。なお、短手方向Ｘの第１端側に配置された外側取付ボス１２０ａと短手方向Ｘの第２端側（図１では右端側）に配置された外側取付ボス１２０ｂとは、高さが等しい。これに対して、内側取付ボス１２０ｃの高さは、この内側取付ボス１２０ｃを挟んで対になって配設されている外側取付ボス１２０ａ，１２０ｂの高さよりも低い。 In the lateral direction X, the inner mounting boss 120c is located between the outer mounting bosses 120a and 120b disposed in pairs. The outer mounting boss 120a disposed on the first end side in the lateral direction X and the outer mounting boss 120b disposed on the second end side in the lateral direction X (right end side in FIG. 1) equal. On the other hand, the height of the inner mounting boss 120c is lower than the heights of the outer mounting bosses 120a and 120b disposed in pairs with the inner mounting boss 120c interposed therebetween.
複数の取付ボス１２０のうち、内側取付ボス１２０ｃは、収容部１１２の少なくとも一部を覆うカバーである収容部カバー４００の固定に使用される。これに対して、外側取付ボス１２０ａ，１２０ｂは、収容部１１２の少なくとも一部に加えて部品取付部１１１の少なくとも一部を覆うカバーである意匠カバー５００の固定に使用される。なお、意匠カバー５００の固定に使用される外側取付ボス１２０ａ，１２０ｂのうち、外側取付ボス１２０ａは、収容部カバー４００の固定に使用される取付ボス１２０を兼ねている。 Among the plurality of mounting bosses 120, the inner mounting boss 120 c is used for fixing the housing portion cover 400 that is a cover that covers at least a part of the housing portion 112. On the other hand, the outer mounting bosses 120 a and 120 b are used for fixing the design cover 500 that is a cover that covers at least a part of the component mounting part 111 in addition to at least a part of the housing part 112. Of the outer mounting bosses 120 a and 120 b used for fixing the design cover 500, the outer mounting boss 120 a also serves as the mounting boss 120 used for fixing the housing portion cover 400.
複数の取付ボス１２０（１２０ａ，１２０ｂ，１２０ｃ）は、その先端側に、いずれも同じ形状の係合部１３０を有している。係合部１３０は、例えば収容部カバー４００の取付軸４１０の先端に形成された係合凹部４２０及び意匠カバー５００の取付軸５１０の先端に形成された係合凹部５２０の両方に係合可能な拡径部である。 The plurality of mounting bosses 120 (120a, 120b, 120c) each have an engaging portion 130 having the same shape on the tip side. For example, the engaging portion 130 can be engaged with both an engaging recess 420 formed at the tip of the mounting shaft 410 of the housing cover 400 and an engaging recess 520 formed at the tip of the mounting shaft 510 of the design cover 500. It is an enlarged diameter part.
図２に示すように、収容部１１２及び収容部カバー４００は、ヘッドカバー本体１１０の短手方向Ｘが短手方向になっているとともに、ヘッドカバー本体１１０の長手方向Ｙが長手方向となっている。また、部品取付部１１１は長手方向Ｙに沿って所定の間隔をあけて並ぶように複数設けられている。 As shown in FIG. 2, in the housing portion 112 and the housing portion cover 400, the short direction X of the head cover body 110 is the short direction, and the long direction Y of the head cover body 110 is the long direction. A plurality of component mounting portions 111 are provided so as to be arranged at predetermined intervals along the longitudinal direction Y.
外側取付ボス１２０ａ，１２０ｂは、いずれも長手方向Ｙに離間させて複数設けられている。一方、内側取付ボス１２０ｃは、長手方向Ｙにおいて、離間させて設けられた外側取付ボス１２０ａ，１２０ｂの間に配設されている。 A plurality of outer mounting bosses 120a and 120b are provided apart from each other in the longitudinal direction Y. On the other hand, the inner mounting boss 120c is disposed between the outer mounting bosses 120a and 120b that are spaced apart in the longitudinal direction Y.
意匠カバー５００は、平面視において略長方形状をなすヘッドカバー本体１１０の外縁沿いであって、その四隅に対応する位置に配置された４つの取付ボス１２０（１２０ａ，１２０ｂ）によって固定される。一方、長尺状をなす収容部カバー４００は、長手方向Ｙに並ぶように配置された２つの外側取付ボス１２０ａと、内側取付ボス１２０ｃとによって、すなわち３つの取付ボス１２０（１２０ａ，１２０ｃ）によって固定される。 The design cover 500 is fixed by four mounting bosses 120 (120a, 120b) arranged along the outer edge of the head cover main body 110 having a substantially rectangular shape in plan view and at positions corresponding to the four corners. On the other hand, the housing cover 400 having a long shape is composed of two outer mounting bosses 120a and inner mounting bosses 120c arranged in the longitudinal direction Y, that is, three mounting bosses 120 (120a, 120c). Fixed.
次に、本実施形態にかかるシリンダヘッドカバー１００の作用について説明する。
シリンダヘッドカバー１００には、その仕様によって、収容部カバー４００か意匠カバー５００のいずれか一方が取り付けられる。ここで、収容部カバー４００と意匠カバー５００とは、ヘッドカバー本体１１０を覆う範囲の広さが異なるため、シリンダヘッドカバー１００には、収容部カバー４００を取り付けるための取付ボスと、意匠カバー５００を取り付けるための取付ボスとが必要になる。
Next, the operation of the cylinder head cover 100 according to the present embodiment will be described.
Either one of the housing cover 400 and the design cover 500 is attached to the cylinder head cover 100 depending on the specifications. Here, since the accommodating portion cover 400 and the design cover 500 are different in the size of the range covering the head cover main body 110, the cylinder head cover 100 is attached with an attachment boss for attaching the accommodating portion cover 400 and the design cover 500. Mounting bosses are required.
ここで、外側取付ボス１２０ａは、収容部カバー４００と意匠カバー５００の両方の取り付けに使用できるように、その配置及び形状が共通化されている。そして、取付ボス１２０ａ，１２０ｃの係合部１３０に収容部カバー４００の係合凹部４２０が係合することにより、シリンダヘッドカバー１００に対して収容部カバー４００が取り付けられる。あるいは、取付ボス１２０ａ，１２０ｂの係合部１３０に意匠カバー５００の係合凹部５２０が係合することにより、シリンダヘッドカバー１００に対して意匠カバー５００が取り付けられる。 Here, the arrangement and shape of the outer mounting boss 120a are made common so that the outer mounting boss 120a can be used for mounting both the housing cover 400 and the design cover 500. And the accommodating part cover 400 is attached with respect to the cylinder head cover 100 when the engaging recessed part 420 of the accommodating part cover 400 engages with the engaging part 130 of the mounting boss | hub 120a, 120c. Alternatively, the design cover 500 is attached to the cylinder head cover 100 by engaging the engagement recesses 520 of the design cover 500 with the engagement portions 130 of the attachment bosses 120 a and 120 b.
すなわち、シリンダヘッドカバー１００の外面側のほぼ全域を覆う大型の意匠カバー５００は、４つの取付ボス１２０（１２０ａ，１２０ｂ）によって固定される。一方、意匠カバー５００よりも小型の収容部カバー４００は、３つの取付ボス１２０（１２０ａ，１２０ｃ）によって固定される。したがって、少ない取付ボス１２０で収容部カバー４００と意匠カバー５００のいずれもがシリンダヘッドカバー１００に対して取り付け可能になる。 In other words, the large design cover 500 that covers almost the entire outer surface of the cylinder head cover 100 is fixed by the four mounting bosses 120 (120a, 120b). On the other hand, the housing cover 400 that is smaller than the design cover 500 is fixed by the three mounting bosses 120 (120a, 120c). Therefore, both the housing cover 400 and the design cover 500 can be attached to the cylinder head cover 100 with a small number of mounting bosses 120.
以上説明した実施形態によれば、以下の効果が得られる。
（１）意匠カバー５００の固定に使用される取付ボス１２０の一部である取付ボス１２０ａが収容部カバー４００の固定に使用される取付ボス１２０と共通化されているため、意匠カバー５００の固定に使用される取付ボスと収容部カバー４００の固定に使用される取付ボスとを全く別々に設ける場合と比較して、無駄な取付ボス１２０の増加を抑制することができる。したがって、無駄な取付ボス１２０の増加を抑制しつつ、意匠カバー５００と収容部カバー４００のいずれもが取り付け可能なシリンダヘッドカバー１００にすることができる。
According to the embodiment described above, the following effects can be obtained.
(1) Since the mounting boss 120a which is a part of the mounting boss 120 used for fixing the design cover 500 is shared with the mounting boss 120 used for fixing the housing cover 400, the design cover 500 is fixed. As compared with a case where the mounting boss used for fixing and the mounting boss used for fixing the housing cover 400 are provided completely separately, an increase in the useless mounting boss 120 can be suppressed. Therefore, it is possible to make the cylinder head cover 100 to which both the design cover 500 and the accommodating portion cover 400 can be attached while suppressing an increase in the useless attachment boss 120.
（２）外側取付ボス１２０ａ，１２０ｂは収容部１１２と部品取付部１１１の双方を挟む位置に対になって配設されている。そのため、外側取付ボス１２０ａ，１２０ｂを使用することにより、収容部１１２と部品取付部１１１の双方を覆う意匠カバー５００を固定することができる。また、内側取付ボス１２０ｃは収容部１１２と部品取付部１１１との間に配設されているため、この内側取付ボス１２０ｃと、内側取付ボス１２０ｃに対して収容部１１２を挟んで位置する外側取付ボス１２０ａとを使用することにより、部品取付部１１１を覆わずに収容部１１２を覆う収容部カバー４００を取り付けることができる。すなわち、外側取付ボス１２０ａに意匠カバー５００を固定する取付ボス１２０としての機能に加え、収容部カバー４００を固定する取付ボス１２０としての機能を具備させ、取付ボス１２０の一部を共通化することができる。 (2) The outer mounting bosses 120a and 120b are arranged in pairs at positions sandwiching both the housing portion 112 and the component mounting portion 111. Therefore, the design cover 500 that covers both the housing portion 112 and the component mounting portion 111 can be fixed by using the outer mounting bosses 120a and 120b. Further, since the inner mounting boss 120c is disposed between the housing portion 112 and the component mounting portion 111, the inner mounting boss 120c and the outer mounting located between the inner mounting boss 120c and the housing portion 112 therebetween. By using the boss 120a, the housing portion cover 400 that covers the housing portion 112 without covering the component mounting portion 111 can be attached. That is, in addition to the function as the mounting boss 120 for fixing the design cover 500 to the outer mounting boss 120a, the function as the mounting boss 120 for fixing the housing cover 400 is provided, and a part of the mounting boss 120 is made common. Can do.
（３）収容部１１２の長手方向Ｙに離間させて設けられた２つの外側取付ボス１２０ａと、収容部１１２を挟んで反対側に位置する１つの内側取付ボス１２０ｃとの少なくとも３点で収容部カバー４００を固定することができるため、少ない取付ボス１２０で効果的に収容部カバー４００を固定することができる。 (3) The accommodating portion at at least three points of two outer mounting bosses 120a provided to be separated in the longitudinal direction Y of the accommodating portion 112 and one inner mounting boss 120c located on the opposite side across the accommodating portion 112 Since the cover 400 can be fixed, the accommodating portion cover 400 can be effectively fixed with a small number of mounting bosses 120.
（４）部品取付部１１１と収容部１１２との間に配設される内側取付ボス１２０ｃの高さが外側取付ボス１２０ａ，１２０ｂの高さよりも高い場合には、部品取付部１１１と収容部１１２との双方を覆う意匠カバー５００を取り付ける際に内側取付ボス１２０ｃが邪魔になる。その点、上記実施形態では、内側取付ボス１２０ｃの高さが、外側取付ボス１２０ａ，１２０ｂの高さよりも低いため、意匠カバー５００を取り付ける際に内側取付ボス１２０ｃが邪魔になりにくい。 (4) When the height of the inner mounting boss 120c disposed between the component mounting portion 111 and the housing portion 112 is higher than the height of the outer mounting bosses 120a and 120b, the component mounting portion 111 and the housing portion 112 are used. When attaching the design cover 500 that covers both, the inner mounting boss 120c becomes an obstacle. In that respect, in the above embodiment, since the height of the inner mounting boss 120c is lower than the height of the outer mounting bosses 120a, 120b, the inner mounting boss 120c is unlikely to become an obstacle when the design cover 500 is mounted.
（５）取付ボス１２０（１２０ａ，１２０ｂ，１２０ｃ）が、いずれも同じ形状の係合部１３０を有しているので、シリンダヘッドカバー１００の構成を簡素化することができる。 (5) Since the mounting bosses 120 (120a, 120b, 120c) all have the engaging portions 130 having the same shape, the configuration of the cylinder head cover 100 can be simplified.
なお、上記実施形態は、これを適宜変更した以下の形態にて実施することもできる。
・収容部カバー４００は、必ずしも収容部１１２の全体を覆う大きさでなくてもよいし、あるいは、収容部１１２に隣接する他の部品等を一緒に覆うようにしてもよい。
In addition, the said embodiment can also be implemented with the following forms which changed this suitably.
-The accommodating part cover 400 does not necessarily need to be the magnitude | size which covers the whole accommodating part 112, or you may make it cover the other components etc. which adjoin the accommodating part 112 together.
・シリンダヘッドカバー１００に意匠カバー５００及び収容部カバー４００以外の別のカバーを取り付ける場合には、意匠カバー５００の固定に使用される取付ボス１２０のうち、少なくとも１つの取付ボス１２０がその別のカバーの固定に使用される取付ボス１２０を兼ねるようにしてもよい。なお、別のカバーとしては、例えば収容部１１２に収容されないワイヤーハーネス３００やヘッドカバー本体１１０に取り付けられる部品などを覆う部品カバーなどが挙げられる。 When attaching another cover other than the design cover 500 and the housing cover 400 to the cylinder head cover 100, at least one mounting boss 120 of the mounting bosses 120 used for fixing the design cover 500 is the other cover. You may make it serve as the attachment boss | hub 120 used for fixation of. In addition, as another cover, the components cover etc. which cover the components etc. which are attached to the wire harness 300 which is not accommodated in the accommodating part 112, the head cover main body 110, etc. are mentioned, for example.
・意匠カバー５００は、全ての部品取付部１１１及び収容部１１２の全体を覆う大きさでなくてもよい。例えば、ヘッドカバー本体１１０から大きく突出する部品がシリンダヘッドカバー１００に取り付けられる場合や、開閉等の操作を行う部品が配置されている場合などには、その部品やその部品を取り付ける部品取付部１１１が意匠カバー５００によって覆われなくてもよい。 The design cover 500 does not have to be large enough to cover all the component attachment portions 111 and the housing portions 112. For example, when a part that largely protrudes from the head cover main body 110 is attached to the cylinder head cover 100, or when a part that performs operations such as opening and closing is arranged, the part and the part attachment part 111 that attaches the part are designed. The cover 500 may not be covered.
・部品取付部１１１は、イグニッションコイルを取り付けるための挿通孔に限らず、例えばエンジン制御に関連する各種センサを取り付ける取付ボスや、電子部品を実装した基板等を取り付けるフレームなどであってもよい。 The component mounting portion 111 is not limited to the insertion hole for mounting the ignition coil, and may be a mounting boss for mounting various sensors related to engine control, a frame for mounting a board on which electronic components are mounted, or the like.
・ワイヤーハーネス３００はイグニッションコイルに接続されるものに限らず、例えばインジェクタや各種センサなど、エンジン制御に関連する各種部品に接続される電線等が対象となる。 -The wire harness 300 is not limited to the one connected to the ignition coil, but includes, for example, electric wires connected to various parts related to engine control such as an injector and various sensors.
・収容部１１２に収容される部品はワイヤーハーネス３００に限らず、例えばインジェクタや各種センサなど、エンジン制御に関連する各種部品を収容部１１２に収容してもよい。 -The components accommodated in the accommodating part 112 are not restricted to the wire harness 300, For example, you may accommodate various parts relevant to engine control, such as an injector and various sensors, in the accommodating part 112. FIG.
・外側取付ボス１２０ａ，１２０ｂの設置数や配置は任意に変更することができる。例えば、外側取付ボス１２０ａ，１２０ｂを１つずつ１対のみ配設してシリンダヘッドカバー１００の構成を簡素化してもよいし、外側取付ボス１２０ａ，１２０ｂを３対以上設けて意匠カバー５００を固定するようにしてもよい。 -The number and arrangement of the outer mounting bosses 120a and 120b can be arbitrarily changed. For example, only one pair of outer mounting bosses 120a and 120b may be provided one by one to simplify the configuration of the cylinder head cover 100, or three or more outer mounting bosses 120a and 120b may be provided to fix the design cover 500. You may do it.
なお、外側取付ボス１２０ａを複数設ける場合には、そのうちの少なくとも１つを収容部カバー４００の固定に使用する一方、収容部カバー４００の固定に使用しない外側取付ボス１２０ａがあってもよい。この構成によれば、外側取付ボス１２０ａ及び収容部１１２の配置の自由度を向上させることができる。 When a plurality of outer mounting bosses 120a are provided, at least one of them may be used for fixing the housing portion cover 400, while there may be an outer mounting boss 120a that is not used for fixing the housing portion cover 400. According to this structure, the freedom degree of arrangement | positioning of the outer side mounting boss | hub 120a and the accommodating part 112 can be improved.
また、対をなして設けられた外側取付ボス１２０ａ，１２０ｂに加えて、対をなさない外側取付ボス１２０を補助的に設けてもよい。この場合には、意匠カバー５００が平面視矩形状でない形状を有している場合にも、その意匠カバー５００をシリンダヘッドカバー１００に対して効率的に固定することができる。 Further, in addition to the outer mounting bosses 120a and 120b provided in pairs, the outer mounting bosses 120 that do not form a pair may be supplementarily provided. In this case, even when the design cover 500 has a shape that is not rectangular in plan view, the design cover 500 can be efficiently fixed to the cylinder head cover 100.
・内側取付ボス１２０ｃの設置数や配置は任意に変更することができる。例えば、収容部１１２や収容部カバー４００の大きさに応じて、内側取付ボス１２０ｃを複数設けてもよい。この場合には、収容部カバー４００をより強固に固定することができる。 -The number and arrangement of the inner mounting bosses 120c can be arbitrarily changed. For example, a plurality of inner mounting bosses 120c may be provided according to the size of the accommodating portion 112 or the accommodating portion cover 400. In this case, the accommodating portion cover 400 can be more firmly fixed.
・取付ボス１２０ａ，１２０ｂ，１２０ｃの高さは任意に変更することができる。例えば、外側取付ボス１２０ａの高さが外側取付ボス１２０ｂよりも高い場合などには、内側取付ボス１２０ｃの高さを外側取付ボス１２０ｂと等しくしてもよい。この構成によれば、意匠カバー５００を取り付ける際に内側取付ボス１２０ｃが邪魔になりにくい。 -The height of mounting boss | hub 120a, 120b, 120c can be changed arbitrarily. For example, when the height of the outer mounting boss 120a is higher than that of the outer mounting boss 120b, the height of the inner mounting boss 120c may be equal to the outer mounting boss 120b. According to this configuration, when the design cover 500 is attached, the inner attachment boss 120c is less likely to get in the way.
・取付ボス１２０の係合部１３０の形状は任意に変更することができる。例えば、係合部１３０は係合凹部、係止孔、係止爪、ねじ穴あるいはヒンジなどでもよい。また、取付ボス１２０ａ，１２０ｂ，１２０ｃの形状が互いに異なってもよいし、長手方向Ｙに並ぶように複数設けられた外側取付ボス１２０同士の形状が互いに異なってもよい。さらに、内側取付ボス１２０ｃが複数設けられる場合には、それらの形状が互いに異なってもよい。この構成によれば、カバー４００，５００を取り付ける向きを規定することができる。 -The shape of the engaging part 130 of the attachment boss | hub 120 can be changed arbitrarily. For example, the engaging portion 130 may be an engaging recess, a locking hole, a locking claw, a screw hole, or a hinge. Moreover, the shapes of the mounting bosses 120a, 120b, 120c may be different from each other, and the shapes of the plurality of outer mounting bosses 120 provided so as to be aligned in the longitudinal direction Y may be different from each other. Further, when a plurality of inner mounting bosses 120c are provided, their shapes may be different from each other. According to this configuration, the direction in which the covers 400 and 500 are attached can be defined.
・収容部１１２の形状や配置は任意に変更することができる。例えば、収容部１１２を収容凹部とした場合には、取付ボス１２０ａ，１２０ｃの高さを低くすることができる。
・１つの収容部１１２に対して、複数の収容部カバー４００を取り付けるようにしてもよい。
-The shape and arrangement | positioning of the accommodating part 112 can be changed arbitrarily. For example, when the accommodating portion 112 is an accommodating recess, the height of the mounting bosses 120a and 120c can be reduced.
-You may make it attach the some accommodating part cover 400 with respect to the one accommodating part 112. FIG.
・収容部１１２を複数設けてもよい。この場合には、複数の収容部１１２を１つの収容部カバー４００で覆ってもよいし、収容部１１２毎に別個の収容部カバー４００を取り付けてもよい。あるいは、１つの収容部カバー４００が複数の収容部１１２にまたがるようにしてもよい。 -A plurality of accommodating portions 112 may be provided. In this case, the plurality of accommodating portions 112 may be covered with one accommodating portion cover 400, or a separate accommodating portion cover 400 may be attached to each accommodating portion 112. Alternatively, one storage unit cover 400 may extend over a plurality of storage units 112.
