Further, the auxiliary rib 49 connects the base end portion on the other side of the flat plate portion 42b of the cylindrical portion 42 and the cap main body portion 41, and has a smaller projecting dimension along the axial direction than the main rib 48. Is formed.

また、対向リブ50は、主としてキャップ本体部41が正面側に凹設された部分で、両側の平板部42a，42cに連続し、各係合部44に対向するように、２枚ずつ合計４枚のリブとして形成されている。 Further, the opposing rib 50 is a portion where the cap body portion 41 is mainly recessed on the front side, and is continuous with the flat plate portions 42a and 42c on both sides, and a total of four opposing ribs 50 so as to face each engaging portion 44. It is formed as a single rib.

また、被取付部21の孔部31の裏面側すなわちカバー体６の内側には、カバー体６をボルトなどの固定具にて取付体あるいは車体に固定する図示しない取付固定部が設けられている。そして、この固着具により、カバー体６が車体に強固に取り付けられ、エアバッグ７の展開時に大きな力が加わった際にもカバー体６が安定して支持される。 An attachment fixing portion (not shown) for fixing the cover body 6 to the attachment body or the vehicle body with a fixing tool such as a bolt is provided on the back side of the hole portion 31 of the attached portion 21, that is, inside the cover body 6. . The fixing member firmly attaches the cover body 6 to the vehicle body, and the cover body 6 is stably supported even when a large force is applied when the airbag 7 is deployed.

次に、このキャップ22の被取付部21への着脱操作を説明する。 Next, the attaching / detaching operation of the cap 22 to the attached portion 21 will be described.

まず、キャップ22を被取付部21に装着する際は、図１(a)及び(b)に示すように、キャップ22の係止部45を孔部31の切欠部33に位置合わせした状態で、被取付部21の表面側から筒状部42を孔本体部32に挿入するとともに係止部45を切欠部33に挿入する。 First, when attaching the cap 22 to the attached portion 21, as shown in FIGS. 1 (a) and 1 (b), the engaging portion 45 of the cap 22 is aligned with the notch 33 of the hole 31. Then, the cylindrical portion 42 is inserted into the hole main body portion 32 from the surface side of the attached portion 21, and the locking portion 45 is inserted into the cutout portion 33.

そして、係止部45が切欠部33を通過した状態で、図１(c)及び(d)に示すように、係止部45と切欠部33との位置がずれるようにキャップ22を所定方向に正規位置まで回動させながらキャップ22をさらに挿入方向に押し込む。この回動については、キャップ22の筒状部42の形状と被取付部21の孔本体部32との形状が相似であることが案内となり、特に、それぞれ略円弧状である辺32dと曲板部42dとが摺接して円滑に案内されるとともに、キャップ22の主リブ47，48が孔本体部32の辺32d，32aに当接することにより、回動範囲が規制される。 Then, with the locking portion 45 passing through the notch 33, the cap 22 is moved in a predetermined direction so that the positions of the locking portion 45 and the notch 33 are shifted as shown in FIGS. The cap 22 is further pushed in the insertion direction while rotating to the normal position. The rotation is guided by the similarity of the shape of the cylindrical portion 42 of the cap 22 and the shape of the hole main body portion 32 of the attached portion 21, and in particular, the side 32d and the curved plate, each of which is substantially arcuate. The portion 42d is slidably contacted and smoothly guided, and the main ribs 47 and 48 of the cap 22 are in contact with the sides 32d and 32a of the hole main body 32, whereby the rotation range is restricted.

そして、さらにキャップ22を挿入方向すなわち軸方向に沿って押し込むことにより、変形部52の付勢力に抗して、傾斜縁部53aが孔本体部32の外縁部に摺接し係合部44が筒状部42の内側方に一旦弾性的に押し込まれ、さらに、孔本体部32を通過した状態で、弾性的に変形した係合部44が外周側に復帰変形する。この状態で、図１(e)及び(f)に示すように、係合部44の係止縁部53bが孔本体部32の裏面側の外縁部に当接するとともに、キャップ本体部41あるいは裏面側の対向リブ50が基板部24の表面側に当接し、両側一対の係合部44とキャップ本体部41あるいは対向リブ50との間に基板部24が弾性的に挟持された状態で、被取付部21へキャップ22ががたつくことなく取り付けられる。 Further, by pushing the cap 22 along the insertion direction, that is, the axial direction, the inclined edge portion 53a is in sliding contact with the outer edge portion of the hole body portion 32 against the urging force of the deformable portion 52, and the engaging portion 44 is cylindrical. The engagement portion 44 that has been elastically deformed once is elastically deformed into the outer peripheral side in a state in which it is once elastically pushed into the inside of the shaped portion 42 and has passed through the hole main body portion 32. In this state, as shown in FIGS. 1E and 1F, the locking edge portion 53b of the engaging portion 44 abuts the outer edge portion on the back surface side of the hole main body portion 32, and the cap main body portion 41 or the back surface. The opposed rib 50 on the side abuts against the surface side of the substrate portion 24, and the substrate portion 24 is elastically sandwiched between the pair of engaging portions 44 on both sides and the cap body portion 41 or the opposed rib 50. The cap 22 is attached to the attachment portion 21 without rattling.

このように、キャップ22を被取付部21に取り付けた状態で、固着具及び孔部31及び孔部31の周辺部の表面側は、キャップ22のキャップ本体部41により覆われ、外観を向上できるとともに、乗員などが固着具を誤って操作することを防止できる。 In this way, in the state where the cap 22 is attached to the attached portion 21, the fixing tool, the hole portion 31, and the surface side of the peripheral portion of the hole portion 31 are covered with the cap body portion 41 of the cap 22, and the appearance can be improved. In addition, an occupant or the like can be prevented from operating the fixing tool by mistake.

また、キャップ22を被取付部21から取り外す際は、装着の手順とは逆に、係止縁部53bを孔本体部32の縁部に摺接させ、変形部52の付勢力に抗して係合部44を変形させて、キャップ22を表面側に引き上げるとともに、キャップ22を回動させて係止部45と切欠部33との位置を合わせ、係止部45を切欠部33に通過させることにより、キャップ22を被取付部21から取り外すことができる。ここで、係止縁部53bの角度は、傾斜縁部53aの角度より大きく設定されているため、キャップ22に装着時よりも大きい力を加えない限り、キャップ22が外れることはない。 Also, when removing the cap 22 from the attached portion 21, the locking edge portion 53b is slidably contacted with the edge portion of the hole main body portion 32 in reverse to the mounting procedure to resist the urging force of the deformable portion 52. The engaging portion 44 is deformed, the cap 22 is pulled up to the surface side, and the cap 22 is rotated to align the positions of the locking portion 45 and the notch portion 33 so that the locking portion 45 passes through the notch portion 33. As a result, the cap 22 can be removed from the attached portion 21. Here, since the angle of the locking edge 53b is set to be larger than the angle of the inclined edge 53a, the cap 22 will not come off unless a larger force is applied to the cap 22 than when the cap 22 is attached.

このように、キャップ22を被取付部21から取り外した状態で、孔部31を介して固着具の着脱操作が可能にり、例えば、固着具を取り外してカバー体６を取り外すなどの保守作業を行うことが可能になる。 In this manner, the fixing tool can be attached / detached through the hole 31 with the cap 22 removed from the attached portion 21. For example, maintenance work such as removing the fixing tool and removing the cover body 6 can be performed. It becomes possible to do.

さらに、自動車の衝突時にエアバッグ装置５が作動してエアバッグ７が展開した場合など、極めて大きな力がキャップ取付部25に加わり、変形部52の付勢力に抗して係合部44が孔本体部32から外れてしまった場合には、係止部45が基板部24の裏面側に当接し、キャップ22を脱落することなく保持できる。さらに、係合部44の係合が外れてキャップ22が傾こうとすると、筒状部42の先端部を延設した延設部46が孔本体部32の外縁部に当接することにより、キャップ22の傾きが抑制され、係止部45が基板部24の裏面側に当接した状態を保持し、キャップ22を被取付部21に確実に保持できる。 Further, when the airbag device 5 is activated and the airbag 7 is deployed at the time of the collision of the automobile, an extremely large force is applied to the cap mounting portion 25, and the engaging portion 44 has a hole against the urging force of the deforming portion 52. When it comes off from the main body 32, the locking portion 45 comes into contact with the back side of the substrate portion 24, and the cap 22 can be held without dropping. Further, when the engagement of the engaging portion 44 is disengaged and the cap 22 is inclined, the extended portion 46 extending from the distal end portion of the cylindrical portion 42 comes into contact with the outer edge portion of the hole main body portion 32, so that the cap The inclination of 22 is suppressed, the state in which the locking portion 45 is in contact with the back surface side of the substrate portion 24 is maintained, and the cap 22 can be reliably held on the attached portion 21.

このように、本実施の形態によれば、キャップ22を被取付部21に取り付けた状態で、固着具及び孔部31及び孔部31の周辺部の表面側をキャップ22で覆い、外観を向上できるとともに、乗員などが固着具を誤って操作することを防止できる。 Thus, according to the present embodiment, with the cap 22 attached to the attached portion 21, the surface of the fixing tool and the hole 31 and the peripheral portion of the hole 31 are covered with the cap 22 to improve the appearance. In addition, it is possible to prevent an occupant or the like from operating the fixing tool by mistake.

また、装着作業及はキャップ22を回動させながら押し込むのみで、作業性良く取り付けできる。特に、回動については、キャップ22の筒状部42の形状と被取付部21の孔本体部32との形状が案内となり、さらに、キャップ22の主リブ47，48が孔本体部32の辺32d，32aに当接することにより、回動範囲が規制され、容易に正規の位置まで回動できる。 In addition, the mounting operation can be performed with good workability simply by pushing the cap 22 while rotating it. In particular, with respect to rotation, the shape of the cylindrical portion 42 of the cap 22 and the shape of the hole main body portion 32 of the attached portion 21 serve as a guide, and the main ribs 47 and 48 of the cap 22 further By abutting on 32d and 32a, the rotation range is restricted, and it can be easily rotated to the normal position.

また、装着作業と反対の動作で、かつ、装着動作時よりも大きな力を加えることにより、キャップ22を取り外し、保守作業などを行うことができる。 Further, the cap 22 can be removed and maintenance work can be performed by applying the force opposite to that during the mounting operation and greater than that during the mounting operation.

さらに、自動車の衝突時にエアバッグ装置５が作動してエアバッグ７が展開した場合など、極めて大きな力が被取付部21あるいはキャップ取付部25に加わり、変形部52の付勢力に抗して係合部44が孔本体部32から外れた場合には、切欠部33とはずれた位置にある係止部45が基板部24の裏面側に当接し、キャップ22を脱落することなく保持できる。さらに、係合部44の係合が外れてキャップ22が傾こうとすると、筒状部42の先端部を延設した延設部46が孔本体部32の外縁部などに当接することにより、キャップ22の傾きが抑制され、係止部45が基板部24の裏面側に当接した状態を保持し、すなわち、係止部45と延設部46とが孔部31に確実に引っ掛かるようにして、キャップ22を被取付部21に確実に保持できる。さらに、キャップ22に直接大きな力が加わった際は、延設部46が変形して孔部31に引っ掛かり、キャップ22を被取付部21に確実に保持できる。 Furthermore, an extremely large force is applied to the mounted portion 21 or the cap mounting portion 25 when the airbag device 5 is activated and the airbag 7 is deployed at the time of the collision of the automobile, and is engaged against the urging force of the deformable portion 52. When the joining portion 44 is disengaged from the hole main body portion 32, the locking portion 45 located at a position deviated from the notch portion 33 abuts on the back surface side of the substrate portion 24, and the cap 22 can be held without falling off. Furthermore, when the engagement of the engaging portion 44 is disengaged and the cap 22 is inclined, the extending portion 46 extending from the distal end portion of the cylindrical portion 42 comes into contact with the outer edge portion of the hole body portion 32, etc. The inclination of the cap 22 is suppressed, and the state in which the locking portion 45 is in contact with the back surface side of the substrate portion 24 is maintained, that is, the locking portion 45 and the extending portion 46 are securely hooked in the hole portion 31. Thus, the cap 22 can be securely held on the attached portion 21. Further, when a large force is directly applied to the cap 22, the extending portion 46 is deformed and caught in the hole portion 31, so that the cap 22 can be securely held on the attached portion 21.

このようにして、エアバッグ装置５の扉部14の近傍など、エアバッグ７の展開時に大きな力が加わる可能性があるカバー体６に対しても、キャップ22を容易に確実に取り付けできる。そこで、キャップ22を保持するために紐などの別部材を用いる必要なく、部品点数や組立工数を削減でき、外観の良いカバー体６の製造コストを低減できる。 In this manner, the cap 22 can be easily and reliably attached to the cover body 6 where a large force may be applied when the airbag 7 is deployed, such as in the vicinity of the door portion 14 of the airbag device 5. Therefore, it is not necessary to use a separate member such as a string to hold the cap 22, so that the number of parts and the number of assembly steps can be reduced, and the manufacturing cost of the cover body 6 having a good appearance can be reduced.

また、キャップ装置20の構成は簡略で、特に、被取付部21は、筒状部などを設ける必要がなく、平板状の基板部24に孔本体部32と切欠部33とを設けた簡略な構成であるとともに、キャップ22は、筒状部42から係止部45及び係合部44を突設するとともに筒状部42の先端部の一部を延設する簡略な構成であり、形状を簡素化して、製造コストを低減できる。 In addition, the configuration of the cap device 20 is simple. In particular, the attached portion 21 does not need to be provided with a cylindrical portion or the like, and is simply provided with a hole body portion 32 and a notch portion 33 in a flat plate-like substrate portion 24. The cap 22 has a simple configuration in which the locking portion 45 and the engaging portion 44 are projected from the cylindrical portion 42 and a part of the tip end portion of the cylindrical portion 42 is extended. Simplification can reduce manufacturing costs.

また、キャップ22及び被取付部21は回転対称形状ではなく、係止部45は１方向のみに突設されているため、誤組付を防止し、キャップ22を被取付部21に対して容易に正しい方向に取り付けできる。 In addition, the cap 22 and the attached portion 21 are not rotationally symmetric, and the locking portion 45 protrudes in only one direction, so that erroneous assembly is prevented and the cap 22 is easily attached to the attached portion 21. Can be mounted in the correct direction.

また、キャップ22は、平板部42a，42b，42cと、略円弧状をなす曲板部42dとを組み合わせて筒状部42を形成したため、コ字状の切り欠きを形成するのみで、平板部42a，42cに弾性変形可能な変形部52を容易に形成できるとともに、剛性が高い曲板部42dに変形せずに強固に係止可能な係止部45を容易に形成できる。 Further, since the cap 22 is formed by combining the flat plate portions 42a, 42b, and 42c and the curved plate portion 42d having a substantially arc shape, the cylindrical portion 42 is formed. The deformable portion 52 that can be elastically deformed can be easily formed on the 42a and 42c, and the locking portion 45 that can be firmly locked without being deformed to the highly rigid curved plate portion 42d can be easily formed.

また、係合部44は、互いに反対側に向かう２方向に突設したため、簡略な構成で安定して孔本体部32に係合してキャップ22を被取付部21に保持可能になるとともに、各係合部44の軸方向に沿った位置にそれぞれ延設部46を設けることにより、２カ所の延設部46でキャップ22を被取付部21に確実に保持できる。 In addition, since the engaging portion 44 protrudes in two directions opposite to each other, the cap 22 can be held in the attached portion 21 by stably engaging the hole body portion 32 with a simple configuration, By providing the extending portions 46 at the positions along the axial direction of the respective engaging portions 44, the cap 22 can be securely held on the attached portion 21 by the two extending portions 46.

また、延設部46は、筒状部42の全体を延設するのではなく、先端部すなわち一般部の一部のみを延設するため、樹脂の使用量を削減し、製造コストを低減できるとともに軽量化できる。 In addition, since the extending portion 46 does not extend the entire cylindrical portion 42, but extends only a part of the distal end portion, that is, the general portion, the amount of resin used can be reduced and the manufacturing cost can be reduced. In addition, it can be reduced in weight.

なお、上記の実施の形態では、延設部46は、両側の係合部44に対応する位置にそれぞれ形成したが、この構成に限られず、一方の係合部44のみに対応する位置に１個の延設部46を延設することもできる。 In the above-described embodiment, the extending portions 46 are formed at positions corresponding to the engaging portions 44 on both sides. However, the present invention is not limited to this configuration, and the extending portions 46 are positioned at positions corresponding to only one engaging portion 44. The extending portions 46 can be extended.

また、キャップ装置20は、ドアマウントのエアバッグ装置５のカバー体６に限られず、インストルメントパネルに備えられるエアバッグ装置のカバー体や、車体のピラーなどを覆う内装部品に設けることもできる。 Further, the cap device 20 is not limited to the cover body 6 of the door-mounted airbag device 5 but can be provided on an interior part that covers a cover body of the airbag device provided in the instrument panel, a pillar of the vehicle body, or the like.

本発明は、例えば、エアバッグ装置のカバー体などの車両の内装部材に適用できる。 The present invention can be applied to an interior member of a vehicle such as a cover body of an airbag device, for example.
