Description

本発明は、自動車のスペアタイヤを保持するために車体に締結具を介して固定されたタイヤキャリアの盗難を防止するタイヤキャリアの盗難防止構造に関する。   The present invention relates to a tire carrier anti-theft structure for preventing the theft of a tire carrier fixed to a vehicle body via a fastener for holding a spare tire of an automobile.

自動車のスペアタイヤを車体の外側に装備するようにしたもの、例えば車体の後部にタイヤキャリアを取り付け、そのタイヤキャリアにスペアタイヤを装備するようにしたものがある。このような車両では、タイヤキャリアにスペアタイヤのホイールディスクを外挿し、ボルトでタイヤキャリアに固定しているだけで、スペアタイヤ全体が車体の外部に露出しているため、その着脱が簡単であり盗難の虞がある。   There are automobile spare tires mounted on the outside of the vehicle body, for example, a tire carrier attached to the rear of the vehicle body and a spare tire mounted on the tire carrier. In such a vehicle, the spare tire wheel disk is extrapolated to the tire carrier and fixed to the tire carrier with bolts, and the entire spare tire is exposed to the outside of the vehicle body, so it can be easily attached and detached. There is a risk of theft.

そのため、従来、スペアタイヤの盗難防止装置が提案されている(例えば、特許文献1参照。)。特許文献1の盗難防止装置は、車室からでなければスペアタイヤをタイヤキャリアに締結するキャップボルトを弛めることができない構成になっている。   Therefore, a conventional anti-theft device for spare tires has been proposed (see, for example, Patent Document 1). The antitheft device of Patent Document 1 has a configuration in which a cap bolt that fastens a spare tire to a tire carrier cannot be loosened unless it is from a passenger compartment.

タイヤキャリアが車体に溶接等で固着された構成であれば、特許文献1のような構成の盗難防止装置によりスペアタイヤの盗難を防止できる。しかし、タイヤキャリアには、車体に溶接等で固着された構成のものではなく、図6(a),(b)に示すように、タイヤキャリア51が車体52(図6(b)に図示)にボルト(締結具)53で固定される構成のものがある。この構成のタイヤキャリア51では、スペアタイヤ54の盗難防止装置(図示せず)を装備しても、スペアタイヤ54のスポーク54aの隙間54bから工具でボルト53による締結を解除して、タイヤキャリア51ごとスペアタイヤ54を車体52から取り外して持ち去ることができる。   If the tire carrier is fixed to the vehicle body by welding or the like, the theft of the spare tire can be prevented by the anti-theft device configured as in Patent Document 1. However, the tire carrier is not fixed to the vehicle body by welding or the like, and as shown in FIGS. 6A and 6B, the tire carrier 51 is a vehicle body 52 (shown in FIG. 6B). In addition, there is a configuration that is fixed by a bolt (fastener) 53. In the tire carrier 51 having this configuration, even if a device for preventing theft of the spare tire 54 (not shown) is provided, the fastening with the bolt 53 is released with a tool from the gap 54b of the spoke 54a of the spare tire 54, and the tire carrier 51 The spare tire 54 can be removed from the vehicle body 52 and carried away.

そこで、図6(b)に示すように、タイヤキャリア51を車体52に固定したボルト53に対する工具55のアクセスを防止するためのブラケット56をタイヤキャリア51にボルト57及びウェルドナット58を介して固定したものもある。このブラケット56が取り付けられた状態でスペアタイヤ54がタイヤキャリア51に取り付けられると、ボルト53に対する工具55のアクセスがブラケット56により阻止される。

Therefore, as shown in FIG. 6B, a bracket 56 for preventing the tool 55 from accessing the bolt 53 that fixes the tire carrier 51 to the vehicle body 52 is fixed to the tire carrier 51 via a bolt 57 and a weld nut 58. Some have done. When the spare tire 54 is attached to the tire carrier 51 with the bracket 56 attached, access of the tool 55 to the bolt 53 is blocked by the bracket 56.
Japanese Utility Model Publication No. 60-67285

ところが、図6(b)に示すように、ブラケット56をボルト57でタイヤキャリア51に取り付ける構成では、ウェルドナット58をタイヤキャリア51溶接する工程が必要になりタイヤキャリア51の製造工程が増える。また、ボルト57をウェルドナット58に螺合して組み付ける作業が必要になり、組み付け時間が増える。   However, as shown in FIG. 6B, in the configuration in which the bracket 56 is attached to the tire carrier 51 with the bolts 57, a process of welding the weld nut 58 to the tire carrier 51 is required, and the manufacturing process of the tire carrier 51 is increased. Further, it is necessary to screw the bolt 57 to the weld nut 58 and assemble it, which increases the assembling time.

本発明は、前記従来の問題に鑑みてなされたものであって、その目的は、ブラケットをボルト及びナットでタイヤキャリアに取付ける構成に比較して、タイヤキャリアの製造工程数を減らすことができるとともに組み付け時間を短縮することができるタイヤキャリアの盗難防止構造を提供することにある。   The present invention has been made in view of the above-described conventional problems, and its object is to reduce the number of manufacturing steps of a tire carrier as compared with a configuration in which a bracket is attached to a tire carrier with bolts and nuts. An object of the present invention is to provide a tire carrier antitheft structure capable of shortening the assembly time.

(第1の実施形態)
以下、本発明を具体化した第1の実施形態を図1及び図2に従って説明する。
図2(a)に示すように、自動車の車体11の後部には、タイヤキャリア12が複数の締結具としてのボルト13及びウェルドナット11a(図1(a),(b)に図示)を介して固定されている。この実施の形態ではタイヤキャリア12は4本のボルト13により固定されるようになっている。スペアタイヤ14は、例えば、タイヤキャリア12側から突設された固定ボルト15に螺合される図示しないロックナットや鍵付きナットによりタイヤキャリア12に固定されるようになっている。なお、ロックナットとは、通常のナットとは違い、通常のレンチでは外すことのできない特殊な形状をしたナットである。
(First embodiment)
A first embodiment embodying the present invention will be described below with reference to FIGS.
As shown in FIG. 2 (a), a tire carrier 12 is connected to a rear portion of a vehicle body 11 of an automobile via a plurality of bolts 13 and weld nuts 11a (shown in FIGS. 1 (a) and 1 (b)) as fasteners. Is fixed. In this embodiment, the tire carrier 12 is fixed by four bolts 13. The spare tire 14 is fixed to the tire carrier 12 by, for example, a lock nut or a lock nut (not shown) that is screwed into a fixing bolt 15 protruding from the tire carrier 12 side. The lock nut is a nut having a special shape that cannot be removed with a normal wrench, unlike a normal nut.

タイヤキャリア12には、タイヤキャリア12を車体11に固定した状態において、ボルト13の締結を解除するための工具30(図1(a)に図示)のボルト13に対する操作を防止する締結部保護部材16が、1個のボルト13に対して取り付けられている。   The tire carrier 12 has a fastening portion protection member for preventing the operation of the tool 30 (shown in FIG. 1A) for releasing the fastening of the bolt 13 when the tire carrier 12 is fixed to the vehicle body 11. 16 is attached to one bolt 13.

図1(a),(c)に示すように、締結部保護部材16は、ウェルドナット11aに螺合されたボルト13を覆う略四角箱状のカバー部16aと、カバー部16aを支持する一対の支持部16bと、タイヤキャリア12にスペアタイヤ14が固定された状態ではスペアタイヤ14と干渉して取外しを阻止する干渉部16cとを備えている。具体的には、締結部保護部材16をタイヤキャリア12に取り付け、スペアタイヤ14をタイヤキャリア12に取り付けた状態では、スペアタイヤ14のホイール14a内面が干渉部16cと干渉しないが、締結部保護部材16を取外し側に移動させると、干渉部16cがホイール14aと干渉する位置関係になっている。干渉部16cは、カバー部16aの基端側と、支持部16bの基端側とを連結する連結部で構成されている。支持部16bは板ばねで構成されている。   As shown in FIGS. 1 (a) and 1 (c), the fastening portion protection member 16 includes a substantially square box-shaped cover portion 16a that covers the bolt 13 screwed to the weld nut 11a, and a pair that supports the cover portion 16a. The support portion 16b and an interference portion 16c that interferes with the spare tire 14 and prevents removal when the spare tire 14 is fixed to the tire carrier 12. Specifically, when the fastening portion protection member 16 is attached to the tire carrier 12 and the spare tire 14 is attached to the tire carrier 12, the inner surface of the wheel 14a of the spare tire 14 does not interfere with the interference portion 16c, but the fastening portion protection member When 16 is moved to the removal side, the interference portion 16c is in a positional relationship where it interferes with the wheel 14a. The interference part 16c is configured by a connecting part that connects the base end side of the cover part 16a and the base end side of the support part 16b. The support part 16b is comprised with the leaf | plate spring.

図1(a),(b)に示すように、タイヤキャリア12は、ボルト13が取り付けられる部分のうち、締結部保護部材16が取り付けられる部分には、ボルト13の挿入側から車体11側に向かって突出する凸部17が形成されている。凸部17は、例えば、プレス成形で形成されるため、図1(b),(c)に示すように、タイヤキャリア12のボルト13の挿入側の面には凹部18が形成されている。凸部17は、スペアタイヤ14の中心に対応するタイヤキャリア12の中心から放射状に延びる仮想線に沿って延びるように形成されている。そして、図1(b)に示すように、凸部17の両側には隙間19が形成され、締結部保護部材16は、一対の支持部16bが隙間19に差し込まれた状態でタイヤキャリア12に取り付けられている。即ち、この実施形態では一対の支持部16bは、車体11とタイヤキャリア12との隙間19に差し込まれる差込み部を構成している。   As shown in FIGS. 1A and 1B, the tire carrier 12 has a portion from which the bolt 13 is attached to a portion to which the fastening portion protection member 16 is attached, from the insertion side of the bolt 13 to the vehicle body 11 side. A projecting portion 17 that protrudes toward the top is formed. Since the convex part 17 is formed by press molding, for example, as shown in FIGS. 1B and 1C, a concave part 18 is formed on the surface of the tire carrier 12 on the insertion side of the bolt 13. The convex portion 17 is formed so as to extend along a virtual line extending radially from the center of the tire carrier 12 corresponding to the center of the spare tire 14. As shown in FIG. 1B, a gap 19 is formed on both sides of the convex portion 17, and the fastening portion protection member 16 is attached to the tire carrier 12 with the pair of support portions 16 b inserted into the gap 19. It is attached. That is, in this embodiment, the pair of support portions 16 b constitutes an insertion portion that is inserted into the gap 19 between the vehicle body 11 and the tire carrier 12.

次に前記のように構成されたタイヤキャリア12の盗難防止構造の作用を説明する。タイヤキャリア12の車体11に対する取付け作業は従来のものと同様にして、ボルト13をウェルドナット11aに螺合させることで行われる。タイヤキャリア12が車体11に取り付けられた後、締結部保護部材16の取付け作業が行われる。締結部保護部材16の取付けは、両支持部16bを隙間19に差し込むことにより行われる。このとき、凸部17が案内部の作用を果たし、締結部保護部材16は、タイヤキャリア12の中心から放射方向に延びる仮想線に沿って移動され、ワンタッチで最終位置に取り付けられる。そして、図2(b)に示すように、締結部保護部材16は支持部16bがタイヤキャリア12に当接する状態に保持される。   Next, the operation of the antitheft structure of the tire carrier 12 configured as described above will be described. The work of attaching the tire carrier 12 to the vehicle body 11 is performed by screwing the bolts 13 into the weld nuts 11a in the same manner as in the prior art. After the tire carrier 12 is attached to the vehicle body 11, the attaching operation of the fastening portion protection member 16 is performed. The fastening portion protection member 16 is attached by inserting both the support portions 16 b into the gap 19. At this time, the convex portion 17 serves as a guide portion, and the fastening portion protection member 16 is moved along a virtual line extending in the radial direction from the center of the tire carrier 12 and attached to the final position with one touch. As shown in FIG. 2B, the fastening portion protection member 16 is held in a state where the support portion 16 b is in contact with the tire carrier 12.

次にスペアタイヤ14がタイヤキャリア12に取り付けられる。スペアタイヤ14のタイヤキャリア12に対する取付けは、公知のタイヤ取外し防止手法を利用した手法で行われる。スペアタイヤ14がタイヤキャリア12に取り付けられた状態では、図1(a)に示すように、ホイール14aの内周面が干渉部16cの近くに配置された状態でボルト13がカバー部16aにより覆われる。そのため、スポーク14bの隙間から工具30を使用してボルト13にアクセスすること、即ちボルト13を工具30で操作することが防止される。従って、締結部保護部材16は、タイヤキャリア12にスペアタイヤ14が固定された状態ではスペアタイヤ14と干渉して取外し不能に、かつスペアタイヤ14が取り外された状態では取外し可能に取り付けられている。   Next, the spare tire 14 is attached to the tire carrier 12. Attachment of the spare tire 14 to the tire carrier 12 is performed by a technique using a known tire removal prevention technique. In the state where the spare tire 14 is attached to the tire carrier 12, as shown in FIG. 1A, the bolt 13 is covered by the cover portion 16a while the inner peripheral surface of the wheel 14a is disposed near the interference portion 16c. Is called. For this reason, it is possible to prevent the bolt 13 from being accessed by using the tool 30 from the gap between the spokes 14 b, that is, operating the bolt 13 with the tool 30. Therefore, the fastening portion protection member 16 is attached so as to be unable to be removed due to interference with the spare tire 14 when the spare tire 14 is fixed to the tire carrier 12 and to be removable when the spare tire 14 is removed. .

また、締結部保護部材16を取り外すために、支持部16bを隙間19から離脱させる方向に移動させようとしても、干渉部16cがホイール14aの内周面と干渉して支持部16bを隙間19から離脱させることができず、締結部保護部材16の取外しが防止される。   Further, in order to remove the fastening portion protection member 16, even if an attempt is made to move the support portion 16 b in a direction in which the support portion 16 b is separated from the gap 19, the interference portion 16 c interferes with the inner peripheral surface of the wheel 14 a, thereby It cannot be made to detach | leave, and removal of the fastening part protection member 16 is prevented.

締結部保護部材16を取り付けるため、タイヤキャリア12に凸部17が設けられている点が従来技術と異なるが、凸部17は、タイヤキャリア12を例えばプレス加工で形成する際に同時に形成されるため、凸部17が設けられても製造工程の工程数は増加しない。そして、従来技術と異なりブラケット56を取り付けるためのウェルドナット58が不要なため、ウェルドナット58をタイヤキャリア12に溶接する工程が不要となる。   Although the convex part 17 is provided in the tire carrier 12 in order to attach the fastening part protection member 16, the convex part 17 is simultaneously formed when the tire carrier 12 is formed by, for example, press working. For this reason, even if the convex portion 17 is provided, the number of manufacturing steps does not increase. And since the weld nut 58 for attaching the bracket 56 is unnecessary unlike the prior art, the process of welding the weld nut 58 to the tire carrier 12 becomes unnecessary.

従って、この実施形態では以下の効果を有する。
(1)スペアタイヤ14を保持するために車体11に複数のボルト13(締結具)を介して固定されたタイヤキャリア12に対して、ボルト13の締結を解除する工具30のボルト13に対する操作を防止する締結部保護部材16が、少なくとも1個のボルト13に対応するように締結部保護部材16専用の締結具を用いずに取り付けられている。そして、締結部保護部材16は、タイヤキャリア12にスペアタイヤ14が固定された状態ではスペアタイヤ14と干渉して取外しを阻止する干渉部16cを備え、かつスペアタイヤ14が取り外された状態では取外し可能に取り付けられている。従って、締結部保護部材16は専用の締結具を用いないため、従来のブラケット56をボルト及びナットでタイヤキャリアに取付ける構成に比較して、タイヤキャリア12の製造工程を減らすことができる。また、専用の締結具で締結部保護部材16を締結する作業がないため、組み付け時間を短縮することができる。
Therefore, this embodiment has the following effects.
(1) For the tire carrier 12 fixed to the vehicle body 11 via a plurality of bolts 13 (fasteners) in order to hold the spare tire 14, an operation on the bolts 13 of the tool 30 for releasing the fastening of the bolts 13 is performed. The fastening portion protection member 16 to be prevented is attached without using a fastener dedicated to the fastening portion protection member 16 so as to correspond to at least one bolt 13. The fastening portion protection member 16 includes an interference portion 16c that interferes with the spare tire 14 to prevent removal when the spare tire 14 is fixed to the tire carrier 12, and is removed when the spare tire 14 is removed. It is attached as possible. Therefore, since the fastening part protection member 16 does not use a dedicated fastener, the manufacturing process of the tire carrier 12 can be reduced as compared with the conventional structure in which the bracket 56 is attached to the tire carrier with bolts and nuts. Moreover, since there is no operation | work which fastens the fastening part protection member 16 with an exclusive fastener, assembly | attachment time can be shortened.

(2)締結部保護部材16は、車体11とタイヤキャリア12との隙間19に差し込まれる支持部16bを備え、支持部16bが車体11とタイヤキャリア12との隙間19に差し込まれた状態で取り付けられている。従って、締結部保護部材16は、支持部16bが車体11とタイヤキャリア12との隙間19に差し込まれることにより簡単に取り付けられる。   (2) The fastening portion protection member 16 includes a support portion 16b that is inserted into the gap 19 between the vehicle body 11 and the tire carrier 12, and is attached in a state where the support portion 16b is inserted into the gap 19 between the vehicle body 11 and the tire carrier 12. It has been. Therefore, the fastening portion protection member 16 is easily attached by inserting the support portion 16 b into the gap 19 between the vehicle body 11 and the tire carrier 12.

(3)締結部保護部材16を取り付けるため、タイヤキャリア12に凸部17が設けられて、凸部17が支持部16bのガイドの役割を果たし、締結部保護部材16を取り付ける際に、締結部保護部材16に加える押圧力の方向が多少ずれていても、所定の位置にワンタッチで取り付けることができる。   (3) Since the convex part 17 is provided in the tire carrier 12 in order to attach the fastening part protection member 16, and the convex part 17 plays the role of the guide of the support part 16b and attaches the fastening part protection member 16, a fastening part Even if the direction of the pressing force applied to the protection member 16 is slightly deviated, it can be attached to a predetermined position with one touch.

(4)従来技術にない凸部17が設けられているが、凸部17は、タイヤキャリア12を例えばプレス加工で形成する際に同時に形成されるため、凸部17が設けられても製造工程数は増加しない。そして、従来技術と異なりブラケット56を取り付けるためのウェルドナット58が不要なため、タイヤキャリア12の製造工程数を減らすことができる。   (4) Although the convex part 17 which does not exist in the prior art is provided, the convex part 17 is formed at the same time when the tire carrier 12 is formed by, for example, press working. The number does not increase. And since the weld nut 58 for attaching the bracket 56 is unnecessary unlike the prior art, the number of manufacturing steps of the tire carrier 12 can be reduced.

(5)締結部保護部材16は、タイヤキャリア12に対する取付け又は取外しの際に、タイヤキャリア12の中心から放射方向に延びる仮想線に沿って移動可能に構成されている。従って、タイヤキャリア12にスペアタイヤ14が固定された状態ではスペアタイヤ14と干渉部16cとが干渉して締結部保護部材16を取外し不能に、かつスペアタイヤ14が取り外された状態では締結部保護部材16を取外し可能に取り付けるための構成が簡単になる。   (5) The fastening portion protection member 16 is configured to be movable along a virtual line extending in the radial direction from the center of the tire carrier 12 when being attached to or detached from the tire carrier 12. Therefore, when the spare tire 14 is fixed to the tire carrier 12, the spare tire 14 and the interference portion 16c interfere with each other so that the fastening portion protection member 16 cannot be removed, and when the spare tire 14 is removed, the fastening portion protection is performed. The structure for detachably attaching the member 16 is simplified.

(第2の実施形態)
次に第2の実施形態を図3(a),(b)に従って説明する。この実施形態は、締結部保護部材16のタイヤキャリア12に対する支持状態の構成が前記第1の実施形態と異なっている。第1の実施形態と同様の部分については同一符号を付してその詳細な説明を省略する。
(Second Embodiment)
Next, a second embodiment will be described with reference to FIGS. This embodiment is different from the first embodiment in the configuration of the fastening portion protection member 16 that supports the tire carrier 12. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

図3(a)に示すように、この実施形態においては、締結部保護部材16は、タイヤキャリア12に形成された孔20に挿通される挿通部としての支持部16bを備え、締結部保護部材16は、挿通部(支持部16b)が孔20に挿通された状態でタイヤキャリア12に取り付けられる。孔20は、タイヤキャリア12を車体11に固定するボルト13の頭部13aより車体11から離れた位置に形成されている。孔20は支持部16bをタイヤキャリア12の中心から放射方向に延びる仮想線に沿って真っ直ぐ挿通し易いように、支持部16bの断面形状より若干大きな形状のものが複数形成されている。支持部16bとカバー部16aとの間隔は、第1の実施形態の締結部保護部材16の場合より狭く形成されている。支持部16bは、孔20を貫通してタイヤキャリア12の内側に突出する部分の長さが、タイヤキャリア12にスペアタイヤ14が固定された状態において、干渉部16cの端部とホイール14a内面との距離より充分大きく、例えば、2倍以上となるように形成されている。図3(b)に示すように、この実施形態では、支持部16bは3本形成されている。従って、この第2の実施形態では、前記第1の実施形態の効果(1)、(2)、(5)と同様の効果を有する。   As shown in FIG. 3A, in this embodiment, the fastening portion protection member 16 includes a support portion 16b as an insertion portion that is inserted through the hole 20 formed in the tire carrier 12, and includes a fastening portion protection member. 16 is attached to the tire carrier 12 in a state where the insertion portion (support portion 16 b) is inserted into the hole 20. The hole 20 is formed at a position farther from the vehicle body 11 than the head 13 a of the bolt 13 that fixes the tire carrier 12 to the vehicle body 11. A plurality of holes 20 having a shape slightly larger than the cross-sectional shape of the support portion 16b are formed so that the support portion 16b can be easily inserted straight along a virtual line extending in the radial direction from the center of the tire carrier 12. The interval between the support portion 16b and the cover portion 16a is formed to be narrower than in the case of the fastening portion protection member 16 of the first embodiment. The support portion 16b has a length of a portion that penetrates the hole 20 and protrudes to the inside of the tire carrier 12, and in a state where the spare tire 14 is fixed to the tire carrier 12, the end portion of the interference portion 16c and the inner surface of the wheel 14a The distance is sufficiently larger than the distance, for example, twice or more. As shown in FIG. 3B, in this embodiment, three support portions 16b are formed. Therefore, the second embodiment has the same effects as the effects (1), (2), and (5) of the first embodiment.

実施形態は前記に限定されるものではなく、例えば、次のように構成してもよい。
○ 締結部保護部材16は、車体11とタイヤキャリア12との間に設けられた隙間19あるいはタイヤキャリア12に設けられた孔20に支持部16bが支持される構成に限らない。例えば、図4(a)に示すように、タイヤキャリア12を車体11に固定するボルト21として、頭部21aに、大径部とその車体側に配置される小径部を有する段付きボルトを使用する。段付きボルト頭部21aの大径部は、車体11との間に隙間を形成し、この隙間に、締結部保護部材16の支持部16bが差し込まれる。締結部保護部材16は、図4(b)に示すように、一対の支持部16bを備えており、その間隔はボルト13の小径部の径にほぼ等しく形成されている。この場合、前記第1及び第2の実施形態と異なり、タイヤキャリア12に凸部17あるいは孔20を形成する必要がなく、タイヤキャリア12として従来のものを使用することができる。なお、図4(a)は図1(b)に対応する模式断面図である。
The embodiment is not limited to the above, and may be configured as follows, for example.
The fastening portion protection member 16 is not limited to the configuration in which the support portion 16b is supported in the gap 19 provided between the vehicle body 11 and the tire carrier 12 or the hole 20 provided in the tire carrier 12. For example, as shown in FIG. 4A, as the bolt 21 for fixing the tire carrier 12 to the vehicle body 11, a stepped bolt having a large diameter portion and a small diameter portion arranged on the vehicle body side is used in the head portion 21a. To do. The large-diameter portion of the stepped bolt head portion 21a forms a gap with the vehicle body 11, and the support portion 16b of the fastening portion protection member 16 is inserted into this gap. As shown in FIG. 4B, the fastening portion protection member 16 includes a pair of support portions 16 b, and the interval between them is formed to be approximately equal to the diameter of the small diameter portion of the bolt 13. In this case, unlike the first and second embodiments, there is no need to form the convex portion 17 or the hole 20 in the tire carrier 12, and a conventional tire carrier 12 can be used. FIG. 4A is a schematic cross-sectional view corresponding to FIG.

○ 図5(a)に示すように、締結部保護部材16のカバー部16aのタイヤキャリア12と対向する面に、ボルト13の頭部13aに嵌合する嵌合部22を突設する。また、カバー部16aの基端からカバー部16aと反対側(図5(a)の下側)に延びる延出部16dを設ける。そして、嵌合部22を頭部13aに嵌合させて、締結部保護部材16をタイヤキャリア12に取り付ける。締結部保護部材16がタイヤキャリア12に取り付けられた状態でスペアタイヤ14がタイヤキャリア12に取り付けられて、延出部16dがスペアタイヤ14と係合する状態となり、締結部保護部材16は、スペアタイヤ14によって車体11側に押圧される。従って、嵌合部22の嵌合力は弱くてよい。この場合も、前記第1及び第2の実施形態と異なり、タイヤキャリア12に凸部17あるいは孔20を形成する必要がなく、タイヤキャリア12として従来のものを使用することができる。   As shown to Fig.5 (a), the fitting part 22 fitted to the head 13a of the volt | bolt 13 is protrudingly provided in the surface facing the tire carrier 12 of the cover part 16a of the fastening part protection member 16. FIG. Further, an extending portion 16d extending from the base end of the cover portion 16a to the side opposite to the cover portion 16a (the lower side in FIG. 5A) is provided. Then, the fitting portion 22 is fitted to the head portion 13 a and the fastening portion protection member 16 is attached to the tire carrier 12. With the fastening portion protection member 16 attached to the tire carrier 12, the spare tire 14 is attached to the tire carrier 12, and the extended portion 16d engages with the spare tire 14. The fastening portion protection member 16 The tire 14 is pressed toward the vehicle body 11 side. Therefore, the fitting force of the fitting part 22 may be weak. Also in this case, unlike the first and second embodiments, it is not necessary to form the convex portion 17 or the hole 20 in the tire carrier 12, and a conventional tire carrier 12 can be used.

○ 締結部保護部材16をタイヤキャリア12に取り付ける構成として、嵌合や挟持等機械的に締結部保護部材16を保持する構成に限らず、締結部保護部材16を磁石で形成し、磁石の吸引力で車体11あるいはタイヤキャリア12に取り付けられる構成としてもよい。例えば、図5(b)に示すように、締結部保護部材16の一部(延出部16d)が車体11に吸着された状態で取り付けられた構成とする。また、タイヤキャリア12を鋼で形成するとともに図5(c)に示すように、タイヤキャリア12の端部を延長して、締結部保護部材16の一部(延出部16d)がタイヤキャリア12に吸着された状態で取り付けられた構成としてもよい。締結部保護部材16は、スペアタイヤ14で車体11側に押圧されるため、磁石の吸引力は弱くてもよい。   ○ The configuration for attaching the fastening portion protection member 16 to the tire carrier 12 is not limited to the configuration in which the fastening portion protection member 16 is mechanically held, such as fitting or clamping, and the fastening portion protection member 16 is formed of a magnet, and the magnet is attracted. It is good also as a structure attached to the vehicle body 11 or the tire carrier 12 with force. For example, as shown in FIG. 5 (b), a part of the fastening portion protection member 16 (extending portion 16 d) is attached in a state of being attracted to the vehicle body 11. Further, the tire carrier 12 is formed of steel and the end portion of the tire carrier 12 is extended as shown in FIG. 5C, and a part of the fastening portion protection member 16 (extension portion 16 d) is the tire carrier 12. It is good also as a structure attached in the state adsorb | sucked to. Since the fastening portion protection member 16 is pressed toward the vehicle body 11 by the spare tire 14, the attractive force of the magnet may be weak.

○ 締結部保護部材16は、カバー部16aが箱状あるいは板状でボルト13,21及びその周囲と対応する部分全体を覆う構成に限らず、工具30のボルト13,21に対するアクセスを阻止する構成であれば、ボルト13,21がホイール14a側から見える形状であってもよい。例えば、図5(d)に示すように、全体を覆うカバー部16aに代えて、板状の保護部16eが隙間を有する状態で設けられた構成としてもよい。また、カバー部16aが複数のスリットを有する構成としてもよい。   The fastening portion protection member 16 is not limited to a configuration in which the cover portion 16a is box-shaped or plate-shaped and covers the bolts 13 and 21 and the entire portion corresponding to the periphery thereof, but a configuration that prevents the tool 30 from accessing the bolts 13 and 21. If so, the bolts 13 and 21 may be visible from the wheel 14a side. For example, as shown in FIG. 5D, instead of the cover portion 16a covering the whole, a plate-like protection portion 16e may be provided in a state having a gap. The cover portion 16a may have a plurality of slits.

○ 締結部保護部材16の取付けあるいは取外しの際の移動方向はタイヤキャリア12の中心から放射方向に延びる仮想線に沿う方向に限らず、タイヤキャリア12に取り付けられたスペアタイヤ14と締結部保護部材16とが干渉して締結部保護部材16の移動が阻止される方向であればよい。   The moving direction when attaching or removing the fastening portion protection member 16 is not limited to the direction along the imaginary line extending in the radial direction from the center of the tire carrier 12, but the spare tire 14 attached to the tire carrier 12 and the fastening portion protection member 16 may interfere with the movement of the fastening portion protection member 16 due to interference.

○ 締結部保護部材16は一個に限らず、複数の締結部保護部材16を異なるボルト13,21と対応する箇所に設けてもよい。
○ タイヤキャリア12を車体11に取り付ける締結具はボルトに限らない。
