Description

本発明は、トノカバーの係止構造に関する。 The present invention relates to a locking structure of a tonneau cover.

従来、車両の荷室を覆う巻取り式のトノカバーを備える車両荷室構造が知られている。例えば下記の特許文献１には、図２〜図４に示される通り、可撓性を有する布状のトノカバー（１４）と、上記トノカバー（１４）を支持する支持部材（トノカバーの後方端部）と、車両荷室の側壁をなす一対のデッキサイドトリムにそれぞれ設けられ、上記支持部材の両端を係止する係止部（２３Ａ，２３Ｂ）等からなる係止構造が開示されている。このうち係止部（２３Ｂ）は、図３および図４に示される通り、車両前後方向に延びるガイド溝と、ガイド溝に車両後方側で連通し、ガイド溝よりも上方において車両前方側に屈曲することで上記支持部材を係止する係止溝とにより構成されている。 Conventionally, a vehicle luggage compartment structure including a retractable tonneau cover that covers the luggage compartment of the vehicle is known.

特許文献１に開示の係止構造は、トノカバー（１４）を引き出したときに係止部（２３Ｂ）がトノカバー（１４）に隠れるため、見栄えが良くなるという利点がある。しかしながら、本発明者らの検討によると、トノカバー（１４）を展設する際には支持部材（トノカバーの後方端部）を係止溝よりも下方のガイド溝に導入する必要があり、大きな荷物を収容している場合や荷物が多い場合等にトノカバーをガイド溝に導入し難いという点において改善の余地があった。 The locking structure disclosed in Patent Document 1 has an advantage that the appearance is improved because the locking portion (23B) is hidden by the tonneau cover (14) when the tonneau cover (14) is pulled out. However, according to the study by the present inventors, when the tonneau cover (14) is extended, it is necessary to introduce a support member (rear end of the tonneau cover) into the guide groove below the locking groove, which is a large load. There was room for improvement in that it was difficult to introduce the tonneau cover into the guide groove when the tonneau cover was stored or when there was a lot of luggage.

本発明は、上記事情に鑑みてなされたものであり、荷物が多い場合等であってもトノカバーをスムーズに係止可能なトノカバーの係止構造を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a tonneau cover locking structure capable of smoothly locking the tonneau cover even when there is a large amount of luggage.

上記課題を解決するため、本発明のトノカバーの係止構造は、車両荷室の側壁をなす一対のデッキサイドトリムと、前記デッキサイドトリムの間にそれぞれ架設されて、可撓性を有するトノカバーを張設状態で支持する支持部材と、を備えて構成される。前記デッキサイドトリムはそれぞれ、前記支持部材の端部を車両前後方向に沿って案内するガイド溝と、前記支持部材の前記端部を係止する係止溝であって、前記ガイド溝に車両後方側で連通し車両後方に向かうにつれて下方に傾斜する傾斜部と、前記傾斜部の下端から車両前方に向かって略水平方向に延びる水平部と、を含む係止溝と、を備えている。そして前記水平部は、その前方部分において、前記トノカバーを介して前記支持部材に加わる前記車両前方に向かう引張り力に抗して前記支持部材を係止可能な構成を備えることに特徴を有する。 In order to solve the above problems, the tonneau cover locking structure of the present invention provides a flexible tonneau cover that is erected between a pair of deck side trims that form a side wall of a vehicle luggage compartment and the deck side trims. It is configured to include a support member that supports it in an upholstered state. The deck side trims are a guide groove that guides the end portion of the support member along the vehicle front-rear direction and a locking groove that locks the end portion of the support member, and is a locking groove that locks the end portion of the support member, and is rearward of the vehicle in the guide groove. It is provided with a locking groove including an inclined portion that communicates on the side and inclines downward toward the rear of the vehicle, and a horizontal portion that extends substantially horizontally from the lower end of the inclined portion toward the front of the vehicle. The horizontal portion is characterized in that, in its front portion, the support member can be locked against a tensile force applied to the support member via the tonneau cover toward the front of the vehicle.

このような構成によると、デッキサイドトリムには、支持部材の係止位置（水平部）よりも上方において支持部材を案内するためのガイド溝が配置されている。そのため、トノカバーをデッキサイドトリムに係止する際には、支持部材を係止位置よりも上方で移動させてガイド溝に導入することができ、支持部材を係止位置よりも下方に移動させる必要がない。その結果、荷室に係止位置よりも上方にまで及ぶ大きな荷物や多量の荷物を収容している場合であっても、トノカバーで荷室を上方から覆うように支持部材を移動させながら、スムーズに支持部材を係止溝に係止することができる。また、係止溝は、ガイド溝よりも車両後方側において下方に傾斜する傾斜部をなし、水平部に接続されている。そのため、使用者は、概ね車両後方に向かう一連の支持部材の移動のみによって支持部材を水平部の前方の係止位置にまで移動できる。 According to such a configuration, the deck side trim is provided with a guide groove for guiding the support member above the locking position (horizontal portion) of the support member. Therefore, when locking the tonneau cover to the deck side trim, the support member can be moved above the locking position and introduced into the guide groove, and it is necessary to move the support member below the locking position. There is no. As a result, even when a large load or a large amount of load extending above the locked position is stored in the luggage compartment, the support member is moved smoothly so as to cover the luggage compartment from above with the tonneau cover. The support member can be locked in the locking groove. Further, the locking groove forms an inclined portion that inclines downward on the rear side of the vehicle with respect to the guide groove, and is connected to the horizontal portion. Therefore, the user can move the support member to the locking position in front of the horizontal portion only by moving the series of support members toward the rear of the vehicle.

また、支持部材を水平部で車両前方に移動させることで、傾斜部と水平部とにより構成される折返し形状によって、支持部材を水平部の前方部分にある係止位置に係止することができる。換言すれば、使用者は、支持部材を概ね車両後方に移動させる操作と、支持部材を水平部で前方に移動させる操作と、の２ステップでトノカバーを係止位置に容易に係止することができる。 Further, by moving the support member to the front of the vehicle in the horizontal portion, the support member can be locked at the locking position in the front portion of the horizontal portion by the folded shape formed by the inclined portion and the horizontal portion. .. In other words, the user can easily lock the tonneau cover at the locking position in two steps: an operation of moving the support member to the rear of the vehicle and an operation of moving the support member to the front in the horizontal portion. can.

また、上記係止構造の好適な一態様において、前記支持部材は棒状をなし、その両端部に前記係止溝に係止される係止部を備え、前記係止溝は、係止溝底面と、前記係止溝底面から立ち上がり、下方を向く上方壁面と、前記係止溝底面の車両前方の端部から立ち上がり、車両後方を向く前方壁面と、前記係止溝底面から立ち上がり、上方を向く下方壁面と、を備えている。そして、前記上方壁面、前記前方壁面、および前記下方壁面はコ字状壁を構成しており、少なくとも前記上方壁面、前記前方壁面、および前記下方壁面のいずれかは、前記支持部材に当接して前記支持部材を係止可能に構成されている。 Further, in a preferred embodiment of the locking structure, the support member has a rod shape and is provided with locking portions to be locked to the locking groove at both ends thereof, and the locking groove is the bottom surface of the locking groove. And, rising from the bottom surface of the locking groove and facing downward, rising from the front end of the vehicle on the bottom surface of the locking groove, rising from the front wall surface facing the rear of the vehicle, rising from the bottom surface of the locking groove and facing upward. It has a lower wall surface. The upper wall surface, the front wall surface, and the lower wall surface form a U-shaped wall, and at least one of the upper wall surface, the front wall surface, and the lower wall surface abuts on the support member. The support member is configured to be lockable.

このような係止構造において、水平部は前方に凹んだコ字状壁を構成し、係止溝は車両前方に向けて閉じられている。これにより、トノカバーを介して支持部材に加わる車両前方に向かう引張り力に抗して、係止溝の水平部に支持部材を確実に係止することができる。 In such a locking structure, the horizontal portion forms a U-shaped wall recessed forward, and the locking groove is closed toward the front of the vehicle. As a result, the support member can be reliably locked to the horizontal portion of the locking groove against the pulling force applied to the support member via the tonneau cover toward the front of the vehicle.

上記係止構造の好適な一態様において、前記係止溝は係止溝底面を備えるとともに、前記傾斜部において前記係止溝底面から立ち上がり車両前方を向く後方壁面を備え、前記後方壁面は、前記デッキサイドトリムの車両後方の縁部に沿うように傾斜されている。 In a preferred embodiment of the locking structure, the locking groove includes a bottom surface of the locking groove, a rear wall surface that rises from the bottom surface of the locking groove and faces the front of the vehicle at the inclined portion, and the rear wall surface is the said. The deck side trim is tilted along the rear edge of the vehicle.

このトノカバーの係止構造においては、デッキサイドトリムに備えられる係止溝の傾斜部の外形がデッキサイドトリムの車両後方の縁部の形状に沿うようにデザインされている。これにより、傾斜部の外形とデッキサイドトリムの車両後方の縁部の形状とに統一感がもたらされ、デッキサイドトリムの意匠性が高められる。また、使用者がトノカバーを係止するとき、傾斜部の外形がデッキサイドトリムの車両後方の縁部の形状に調和することで、車両後方に移動させた支持部材を視覚的効果によって車両後方の縁部に沿って下方に移動させる動作が自然に促される。このことにより、使用者は、意図することなくトノカバーを傾斜部の下端にまで自然に移動することができ、トノカバーをより一層スムーズに係止することができる。 In the locking structure of the tonneau cover, the outer shape of the inclined portion of the locking groove provided on the deck side trim is designed to follow the shape of the rear edge of the deck side trim. This brings a sense of unity between the outer shape of the inclined portion and the shape of the rear edge of the deck side trim, and enhances the design of the deck side trim. In addition, when the user locks the tonneau cover, the outer shape of the inclined portion matches the shape of the rear edge of the deck side trim, so that the support member moved to the rear of the vehicle can be visually affected at the rear of the vehicle. The movement to move downward along the edge is naturally promoted. As a result, the user can unintentionally move the tonneau cover to the lower end of the inclined portion, and the tonneau cover can be locked even more smoothly.

上記係止構造の好適な一態様において、前記ガイド溝と前記係止溝とは、底面が面一の溝状に構成されており、前記底面は、前記デッキサイドトリムを車両の被取付部材に固定するためのクリップ部材を取り付けるための取付部を備え、前記取付部は、前記傾斜部と前記水平部との間に形成される扇形の折曲領域の近傍に設けられている。このような係止構造によると、クリップ部材の取付部が設けられる底面には、取付部の近傍に扇形の折曲領域が形成されるため、クリップ部材の取付けに際しこの折曲領域を作業空間として利用することができる。これにより、組付け作業者は、被取付部材へのデッキサイドトリムの取付作業を容易に行うことができる。 In a preferred embodiment of the locking structure, the guide groove and the locking groove are formed in a groove shape having a flush bottom surface, and the bottom surface uses the deck side trim as a mounted member of a vehicle. A mounting portion for mounting a clip member for fixing is provided, and the mounting portion is provided in the vicinity of a fan-shaped bent region formed between the inclined portion and the horizontal portion. According to such a locking structure, a fan-shaped bent region is formed in the vicinity of the mounting portion on the bottom surface where the mounting portion of the clip member is provided. Therefore, when mounting the clip member, this bent region is used as a work space. It can be used. As a result, the assembling worker can easily attach the deck side trim to the member to be attached.

本発明によれば、大きな荷物を収容している場合や荷物が多い場合等であっても、スムーズに係止できるトノカバーの係止構造が提供される。 According to the present invention, there is provided a locking structure of a tonneau cover that can be smoothly locked even when a large load is accommodated or a large amount of load is stored.

本発明の実施形態を図１ないし図５によって説明する。図１および図２は、一実施形態に係るトノカバーの係止構造を採用した車両１０の荷室１１内の一例を示している。車両１０は、後部に荷室１１（車両荷室）が設けられている。車両１０の最後部には図示しないバックドアが備えられ、荷室１１は、バックドアに対応する後部開口１２からアクセス可能とされている。また、荷室１１の車両前方には、シートバックの裏面１３Ａが略鉛直方向に沿って立ち上がる形で後部座席１３が配設されている。荷室１１の上方には、図２に示すように、水平方向に沿って延在する形でトノカバー装置１４が配設されている。なお、トノカバー装置１４は、巻き取られた状態では、図１に示すようにトノカバー前方係止部２３に係脱可能に係止されている。荷室１１は、そのレイアウトに応じて、トノカバー装置１４を取り外して用いることができる。 <Embodiment>
Embodiments of the present invention will be described with reference to FIGS. 1 to 5. 1 and 2 show an example in the luggage compartment 11 of the vehicle 10 adopting the tonneau cover locking structure according to the embodiment. The vehicle 10 is provided with a luggage compartment 11 (vehicle luggage compartment) at the rear. A back door (not shown) is provided at the rear end of the vehicle 10, and the luggage compartment 11 is accessible from a rear opening 12 corresponding to the back door. Further, in front of the vehicle in the luggage compartment 11, a rear seat 13 is arranged so that the back surface 13A of the seat back stands up in a substantially vertical direction. As shown in FIG. 2, a tonneau cover device 14 is arranged above the luggage compartment 11 so as to extend along the horizontal direction. In the wound state, the tonneau cover device 14 is detachably locked to the tonneau cover front locking portion 23 as shown in FIG. The luggage compartment 11 can be used by removing the tonneau cover device 14 according to its layout.

荷室１１は、図１および図２に示すように、側壁をなす一対のデッキサイドトリム２０，２０と、床面１５Ａをなすデッキボード１５とを備えている。なお、図１および図２においては、手前側（車両１０の進行方向左側）のデッキサイドトリム２０を省略して示すとともに、デッキサイドトリム２０の形状を簡略化して示している。デッキボード１５は、水平方向に沿って延在する板状をなし、その上面（床面）１５Ａに荷物を載置可能とされている。デッキボード１５の下方には、いわゆるラゲージアンダースペースと呼ばれる収納空間が形成されている。なお、本実施形態では、デッキボード１５が一の板状部材で構成されるものを例示したが、デッキボードは複数の板状部材に分割して構成されていてもよい。 As shown in FIGS. 1 and 2, the luggage compartment 11 includes a pair of deck side trims 20 and 20 forming side walls and a deck board 15 forming a floor surface 15A. In addition, in FIGS. 1 and 2, the deck side trim 20 on the front side (left side in the traveling direction of the vehicle 10) is omitted, and the shape of the deck side trim 20 is shown in a simplified form. The deck board 15 has a plate shape extending along the horizontal direction, and luggage can be placed on the upper surface (floor surface) 15A thereof. A storage space, a so-called luggage underspace, is formed below the deck board 15. In the present embodiment, the deck board 15 is configured by one plate-shaped member, but the deck board may be divided into a plurality of plate-shaped members.

デッキサイドトリム２０は、図１および図２に示すように、おおよそ鉛直方向及び車両前後方向に沿って延在する板状をなし、その車幅方向内側を向く面が荷室１１内に臨む内面２０Ａとされている。なお、このようなデッキサイドトリム２０は、トランクサイドトリム又はラゲージサイドトリムと呼ばれることもある。一対のデッキサイドトリム２０，２０は、荷室１１の左右の側壁で左右対称に構成されている。以下の説明においては、図１の奥側（車両１０の進行方向右側）に位置するデッキサイドトリム２０について説明するとともに、手前側（車両１０の進行方向左側）に位置するデッキサイドトリムについての説明を適宜省略する場合がある。 As shown in FIGS. 1 and 2, the deck side trim 20 has a plate shape extending substantially along the vertical direction and the vehicle front-rear direction, and the surface facing inward in the vehicle width direction faces the inside of the luggage compartment 11. It is said to be 20A. The deck side trim 20 may be referred to as a trunk side trim or a luggage side trim. The pair of deck side trims 20 and 20 are symmetrically configured on the left and right side walls of the luggage compartment 11. In the following description, the deck side trim 20 located on the back side (right side in the traveling direction of the vehicle 10) of FIG. 1 will be described, and the deck side trim 20 located on the front side (left side in the traveling direction of the vehicle 10) will be described. May be omitted as appropriate.

デッキサイドトリム２０には、その車両前方かつ下方に、ホイールハウスに倣う形で荷室１１内に膨出するホイールハウス部２１が設けられている。また、デッキサイドトリム２０は、その後端部２２が後部開口１２の開口縁に倣う形とされている。デッキサイドトリム２０は、図３に示すように、ホイールハウス部２１と、後端部２２以外の部分を占める一般部２５が平行状をなして配設されている。また、荷室１１は後部開口１２に向けて後端部２２においてやや狭くなるように構成されている。そのため、一対のデッキサイドトリム２０，２０の間の車幅方向における寸法（離間距離）は、図３に示すように、一般部２５，２５よりも後端部２２，２２において相対的に小さく（狭く）なっている。 The deck side trim 20 is provided with a wheel house portion 21 that bulges into the luggage compartment 11 in a shape that imitates the wheel house, in front of and below the vehicle. Further, the deck side trim 20 has a shape in which the rear end portion 22 follows the opening edge of the rear opening 12. As shown in FIG. 3, the deck side trim 20 is arranged so that the wheel house portion 21 and the general portion 25 occupying a portion other than the rear end portion 22 are arranged in parallel. Further, the luggage compartment 11 is configured to be slightly narrowed at the rear end portion 22 toward the rear opening 12. Therefore, as shown in FIG. 3, the dimension (separation distance) between the pair of deck side trims 20 and 20 in the vehicle width direction is relatively smaller at the rear end portions 22 and 22 than at the general portions 25 and 25 (as shown in FIG. 3). (Narrow).

そして、一対のデッキサイドトリム２０，２０は、その間において、トノカバー装置１４を架設可能に構成されている。具体的には、デッキサイドトリム２０には、ホイールハウス部２１の上方の一般部２５に、トノカバー前方係止部２３が設けられている。また、デッキサイドトリム２０には、後端部２２の上部にトノカバー後方係止部２４が設けられている。そのため、一対のデッキサイドトリム２０，２０の車幅方向における離間距離（間隔）は、トノカバー前方係止部２３，２３の位置よりも、トノカバー後方係止部２４，２４の位置において相対的に小さい（狭い）。デッキサイドトリム２０においてトノカバー装置１４を架設するための具体的な構成、すなわちトノカバー前方係止部２３およびトノカバー後方係止部２４（ガイド溝３０および係止溝４０）の構成については、後に説明する。 The pair of deck side trims 20 and 20 are configured so that the tonneau cover device 14 can be erected between them. Specifically, the deck side trim 20 is provided with a tonneau cover front locking portion 23 in a general portion 25 above the wheel house portion 21. Further, the deck side trim 20 is provided with a tonneau cover rear locking portion 24 above the rear end portion 22. Therefore, the separation distance (interval) of the pair of deck side trims 20 and 20 in the vehicle width direction is relatively smaller at the positions of the tonneau cover rear locking portions 24 and 24 than at the positions of the tonneau cover front locking portions 23 and 23. (narrow). The specific configuration for installing the tonneau cover device 14 on the deck side trim 20, that is, the configurations of the tonneau cover front locking portion 23 and the tonneau cover rear locking portion 24 (guide groove 30 and locking groove 40) will be described later. ..

トノカバー装置１４は、大まかな構成として、ハウジング１４ａと、面状部材（トノカバー）１４ｂと、支持部材５０と、図示しない巻取手段と、を備えている。面状部材１４ｂは、可撓性を有する素材によって構成され、荷室１１を上方で覆うことで荷室１１に収容された荷物等を車外からの視線や紫外線等から遮る役割を果たす。面状部材１４ｂは、略方形の布状であって、一端（一辺）が支持部材５０によって支持されており、他端（上記一辺に対向する他の一辺）が巻取手段に固定されている。面状部材１４ｂの支持部材５０に支持されている側の端部は、図３に示すように荷室１１の後端部２２の形状に対応しており、車幅方向の寸法が巻取手段に固定されている側の他端と比較して相対的に小さい。巻取手段は、面状部材１４ｂの他端に接続された状態でハウジング１４ａ内に収容されている。本実施形態の巻取手段は、面状部材１４ｂを自動的に撓みなく巻取ることで、面状部材１４ｂをハウジング１４ａ内に収容できるように構成されている。ハウジング１４ａは、巻取手段を収容するとともに、巻取手段によって長尺ロール状に巻取られた面状部材１４ｂを収容する長尺の収容ケースである。本実施形態のハウジング１４ａは、断面形状が略正方形の角筒状に構成されている。ハウジング１４ａには、面状部材１４ｂの引き出しや巻き取りの際に面状部材１４ｂが出入りするための開口部１４ｄが長手方向に沿って設けられている。ハウジング１４ａの長手方向の端部には、トノカバー前方係止部２３に係止される係止部１４ｃが備えられている。 The tonneau cover device 14 includes a housing 14a, a planar member (tonneau cover) 14b, a support member 50, and a winding means (not shown) as a rough configuration. The planar member 14b is made of a flexible material, and by covering the luggage compartment 11 above, it serves to block the luggage and the like contained in the luggage compartment 11 from the line of sight from the outside of the vehicle, ultraviolet rays, and the like. The planar member 14b has a substantially rectangular cloth shape, one end (one side) is supported by the support member 50, and the other end (the other side facing the one side) is fixed to the winding means. .. As shown in FIG. 3, the end portion of the planar member 14b on the side supported by the support member 50 corresponds to the shape of the rear end portion 22 of the luggage compartment 11, and the dimension in the vehicle width direction is the winding means. It is relatively small compared to the other end of the side fixed to. The winding means is housed in the housing 14a in a state of being connected to the other end of the planar member 14b. The winding means of the present embodiment is configured so that the planar member 14b can be accommodated in the housing 14a by automatically winding the planar member 14b without bending. The housing 14a is a long storage case that houses the winding means and also houses the planar member 14b that is wound in a long roll shape by the winding means. The housing 14a of the present embodiment is formed in a square tubular shape having a substantially square cross-sectional shape. The housing 14a is provided with an opening 14d along the longitudinal direction for the planar member 14b to enter and exit when the planar member 14b is pulled out or wound up. A locking portion 14c that is locked to the tonneau cover front locking portion 23 is provided at the longitudinal end of the housing 14a.

支持部材５０は棒状をなしている。支持部材５０は、面状部材１４ｂの一端に設けられて面状部材１４ｂを張設状態で支持するための部材である。支持部材５０には、巻取手段によるハウジング１４ａに向かう引張り力が面状部材１４ｂを介して作用している。支持部材５０の長手方向の両方の端部には、トノカバー後方係止部２４，２４に係り合う係止部５２，５２が備えられている。支持部材５０の長手方向の寸法は、ハウジング１４ａの開口部１４ｄの長手方向の寸法より長い。支持部材５０の短手方向（面状部材１４ｂを平面にしたとき、その平面に直交する方向）の寸法は、ハウジング１４ａの開口部１４ｄの短手方向の寸法より大きい。そのため、面状部材１４ｂが巻取手段によってハウジング１４ａ内に巻き取られた場合でも、支持部材５０は開口部１４ｄを通過できずにハウジング１４ａの外に留まる。したがって、巻き取られた状態のトノカバーを使用する際には、ハウジング１４ａから支持部材５０を引き離すことで面状部材１４ｂを引き出すことができる。また、面状部材１４ｂが引き出されているときには、巻取手段が面状部材１４ｂを巻き取ろうとすることにより、支持部材５０にはハウジング１４ａの方向に向かう引っ張り力が作用する。支持部材５０は、その長手方向を車幅方向に一致させた姿勢で荷室１１に配される。本実施形態における支持部材５０の係止部５２は、図４に示すように、長手方向に直交する断面形状が四角形を呈している。具体的には、係止部５２の断面形状は、面状部材１４ｂが水平となるように配置したとき、面状部材１４ｂに近い側である巻取側の端部５２ａの寸法よりも面状部材１４ｂから離れる側である末端側の端部５２ｂの寸法の方が大きくなるように構成されている。言い換えれば、係止部５２を水平面に配置したとき、係止部５２の上面は末端側の端部５２ｂから巻取側の端部５２ａに向けて徐々に下方に傾斜されている。ただし、係止部５２の形状はこれに限定されない。 The support member 50 has a rod shape. The support member 50 is a member provided at one end of the planar member 14b to support the planar member 14b in an stretched state. A tensile force toward the housing 14a by the winding means acts on the support member 50 via the planar member 14b. Both ends of the support member 50 in the longitudinal direction are provided with locking portions 52, 52 that engage the tonneau cover rear locking portions 24, 24. The longitudinal dimension of the support member 50 is longer than the longitudinal dimension of the opening 14d of the housing 14a. The dimension of the support member 50 in the lateral direction (the direction orthogonal to the plane when the planar member 14b is made flat) is larger than the dimension of the opening 14d of the housing 14a in the lateral direction. Therefore, even when the planar member 14b is wound into the housing 14a by the winding means, the support member 50 cannot pass through the opening 14d and stays outside the housing 14a. Therefore, when using the tonneau cover in the wound state, the planar member 14b can be pulled out by pulling the support member 50 away from the housing 14a. Further, when the planar member 14b is pulled out, the winding means tries to wind the planar member 14b, so that a pulling force acting in the direction of the housing 14a acts on the support member 50. The support member 50 is arranged in the luggage compartment 11 in a posture in which the longitudinal direction thereof coincides with the vehicle width direction. As shown in FIG. 4, the locking portion 52 of the support member 50 in the present embodiment has a quadrangular cross-sectional shape orthogonal to the longitudinal direction. Specifically, the cross-sectional shape of the locking portion 52 is more planar than the dimension of the winding-side end 52a, which is closer to the planar member 14b when the planar member 14b is arranged horizontally. The dimension of the end portion 52b on the terminal side, which is the side away from the member 14b, is configured to be larger. In other words, when the locking portion 52 is arranged on a horizontal plane, the upper surface of the locking portion 52 is gradually inclined downward from the end portion 52b on the terminal side toward the end portion 52a on the winding side. However, the shape of the locking portion 52 is not limited to this.

トノカバー装置１４は、図２に示すように、一対のデッキサイドトリム２０，２０にそれぞれ架設されて、可撓性を有する面状部材１４ｂを張設する構成とされている。具体的には、トノカバー装置１４のハウジング１４ａと支持部材５０とは、デッキサイドトリム２０に設けられたトノカバー前方係止部２３とトノカバー後方係止部２４とにそれぞれ架設される。このとき、一対のハウジング１４ａと支持部材５０とは、デッキサイドトリム２０，２０の間で互いに平行状をなし、面状部材１４ｂを撓みなく張設することができる。 As shown in FIG. 2, the tonneau cover device 14 is erected on a pair of deck side trims 20 and 20, respectively, and has a structure in which a flexible planar member 14b is stretched. Specifically, the housing 14a of the tonneau cover device 14 and the support member 50 are erected on the tonneau cover front locking portion 23 and the tonneau cover rear locking portion 24 provided on the deck side trim 20, respectively. At this time, the pair of housings 14a and the support member 50 are parallel to each other between the deck side trims 20 and 20, and the planar member 14b can be stretched without bending.

トノカバー前方係止部２３は、図３に示すように、デッキサイドトリム２０の一般部２５の内面２０Ａから車幅方向の外側に凹む凹部として構成されている。この凹部は、ハウジング１４ａの長手方向に直行する断面に対応した形状の底部２３ａを備えている。ハウジング１４ａの両端に設けられた係止部１４ｃは、長手方向（車幅方向）外側に伸びる方向に付勢された状態で伸縮可能に構成されている。ハウジング１４ａは、係止部１４ｃが伸長した状態における長手方向の寸法が、対向する凹部の底部２３ａの間の距離よりも長くなり得る。また、ハウジング１４ａは、係止部１４ｃが縮短した状態における長手方向の寸法が、対向する凹部周縁（一般部２５の内面２０Ａ）の間の距離よりも短くなり得る。 As shown in FIG. 3, the tonneau cover front locking portion 23 is configured as a recess recessed outward from the inner surface 20A of the general portion 25 of the deck side trim 20 in the vehicle width direction. The recess is provided with a bottom portion 23a shaped to correspond to a cross section perpendicular to the longitudinal direction of the housing 14a. The locking portions 14c provided at both ends of the housing 14a are configured to be expandable and contractible in a state of being urged in a direction extending outward in the longitudinal direction (vehicle width direction). The housing 14a may have a longitudinal dimension in the extended state of the locking portion 14c, which may be longer than the distance between the bottoms 23a of the opposing recesses. Further, the housing 14a may have a longitudinal dimension in a state where the locking portion 14c is shortened, which may be shorter than the distance between the peripheral edges of the recesses (inner surface 20A of the general portion 25) facing each other.

このような構成のトノカバー装置１４は、以下の手順でデッキサイドトリム２０，２０間に架設することができる。すなわち、まず、ハウジング１４ａの一方の係止部１４ｃを一方のトノカバー前方係止部２３の凹部に挿入し、その底部２３ａに押し当てる。これにより当該一方の係止部１４ｃを縮短状態とする。次いで、ハウジング１４ａの他方の係止部１４ｃを長手方向における内側（中心側）に向けて押さえ、当該他方の係止部１４ｃを縮短状態にする。この状態で、当該係止部１４ｃを他方のトノカバー前方係止部２３の凹部に移動させ、両方の係止部１４ｃの縮短状態を開放する。すると、両方の係止部１４ｃは凹部内で外側に伸長し、両方の係止部１４ｃが対向する凹部内でそれぞれ伸長状態となる。これにより、トノカバー装置１４は、荷室１１の前方で荷室１１の上方に係脱可能に係止される。 The tonneau cover device 14 having such a configuration can be installed between the deck side trims 20 and 20 by the following procedure. That is, first, one of the locking portions 14c of the housing 14a is inserted into the recess of the one locking portion 23 in front of the tonneau cover, and the housing 14a is pressed against the bottom portion 23a. As a result, the one locking portion 14c is brought into a shortened state. Next, the other locking portion 14c of the housing 14a is pressed toward the inside (center side) in the longitudinal direction, and the other locking portion 14c is brought into a shortened state. In this state, the locking portion 14c is moved to the recess of the other tonneau cover front locking portion 23 to release the shortened state of both locking portions 14c. Then, both the locking portions 14c extend outward in the recesses, and both locking portions 14c are in an extended state in the opposing recesses. As a result, the tonneau cover device 14 is engageably and detachably locked above the luggage compartment 11 in front of the luggage compartment 11.

トノカバー後方係止部２４は、図３ないし図６に示すように、ガイド溝３０と係止溝４０とを備える。本発明におけるガイド溝３０と係止溝４０とによって、トノカバー後方係止部２４が構成されている。以下、ガイド溝３０と係止溝４０とについて詳しく説明する。 As shown in FIGS. 3 to 6, the tonneau cover rear locking portion 24 includes a guide groove 30 and a locking groove 40. The tonneau cover rear locking portion 24 is configured by the guide groove 30 and the locking groove 40 in the present invention. Hereinafter, the guide groove 30 and the locking groove 40 will be described in detail.

ガイド溝３０は、支持部材５０の係止部５２を車両前後方向に沿って係止溝４０に案内する。ガイド溝３０は、図３ないし図５に示すように、車幅方向外側に凹むとともに、車両前後方向に沿って延びる溝状に設けられている。具体的には、ガイド溝３０は、後端部２２の内面２０Ａより奥方（車幅方向外側）に後退するガイド溝底面３１と、ガイド溝底面３１の上端から内面２０Ａに向けて立ち上がる上側壁面３２と、ガイド溝底面３１の下端から立ち上がる下側壁面３３と、を有して構成されている。言い換えれば、ガイド溝３０は、内面２０Ａと上側壁面３２とガイド溝底面３１とが段差状に構成されるとともに、内面２０Ａと下側壁面３３とガイド溝底面３１とが段差状に構成されている。なお、図４におけるＰ１は、上側壁面３２に沿って係止部５２を移動させたときの係止部５２の配置を例示したものであり、Ｈ１は位置Ｐ１における係止部５２の高さ（上下方向の位置）を示す。 The guide groove 30 guides the locking portion 52 of the support member 50 to the locking groove 40 along the vehicle front-rear direction. As shown in FIGS. 3 to 5, the guide groove 30 is provided in a groove shape that is recessed outward in the vehicle width direction and extends along the vehicle front-rear direction. Specifically, the guide groove 30 includes a guide groove bottom surface 31 that recedes from the inner surface 20A of the rear end portion 22 to the back (outside in the vehicle width direction), and an upper wall surface 32 that rises from the upper end of the guide groove bottom surface 31 toward the inner surface 20A. And a lower side wall surface 33 rising from the lower end of the guide groove bottom surface 31. In other words, in the guide groove 30, the inner surface 20A, the upper wall surface 32, and the guide groove bottom surface 31 are formed in a stepped shape, and the inner surface 20A, the lower side wall surface 33, and the guide groove bottom surface 31 are formed in a stepped shape. .. Note that P1 in FIG. 4 illustrates the arrangement of the locking portion 52 when the locking portion 52 is moved along the upper wall surface 32, and H1 is the height of the locking portion 52 at the position P1. (Position in the vertical direction) is shown.

ここで、ガイド溝底面３１は一般部２５の内面２０Ａより滑らかに連続している。一対のデッキサイドトリム２０，２０に設けられるガイド溝底面３１，３１の間の寸法（車幅方向の距離）は、支持部材５０が車幅方向においてクリアランスを有して配置できる程度の大きさとされている。また、上側壁面３２および下側壁面３３は、一般部２５に対して前方（車幅方向内側）に突出する後端部２２の内面２０Ａとガイド溝底面３１とを繋ぐ壁面として構成されている。したがって、上側壁面３２および下側壁面３３の突出高さ、言い換えれば、後端部２２の内面２０Ａとガイド溝底面３１とのギャップ（すなわち、ガイド溝３０の深さ）は、ガイド溝３０の最も車両前方となる位置においてゼロであり、車両後方に向かうにつれて徐々に大きくなっている。そしてガイド溝３０の幅寸法（上側壁面３２と下側壁面３３との間の内寸）は、車両前方側において大きく、車両後方に向かうにつれて徐々に小さくなるように構成されている。ガイド溝３０の幅寸法は、支持部材５０の係止部５２が十分なゆとりをもって移動できる程度の大きさとされている。このような構成により、ガイド溝３０は、車両前方の広い範囲から支持部材５０を係止溝４０へとスムーズに案内することができる。 Here, the bottom surface 31 of the guide groove is smoothly continuous from the inner surface 20A of the general portion 25. The dimensions (distance in the vehicle width direction) between the guide groove bottom surfaces 31 and 31 provided on the pair of deck side trims 20 and 20 are large enough to allow the support member 50 to be arranged with a clearance in the vehicle width direction. ing. Further, the upper wall surface 32 and the lower side wall surface 33 are configured as a wall surface connecting the inner surface 20A of the rear end portion 22 projecting forward (inside in the vehicle width direction) with respect to the general portion 25 and the guide groove bottom surface 31. Therefore, the protruding heights of the upper wall surface 32 and the lower wall surface 33, in other words, the gap between the inner surface 20A of the rear end portion 22 and the bottom surface 31 of the guide groove (that is, the depth of the guide groove 30) is the most of the guide groove 30. It is zero at the position in front of the vehicle, and gradually increases toward the rear of the vehicle. The width dimension of the guide groove 30 (inner dimension between the upper wall surface 32 and the lower wall surface 33) is large on the front side of the vehicle and gradually decreases toward the rear of the vehicle. The width dimension of the guide groove 30 is set so that the locking portion 52 of the support member 50 can move with sufficient clearance. With such a configuration, the guide groove 30 can smoothly guide the support member 50 to the locking groove 40 from a wide range in front of the vehicle.

係止溝４０は、支持部材５０の係止部（端部）５２を固定する。係止溝４０は、図３ないし図５に示すように、後端部２２の内面２０Ａから車幅方向外側に凹むとともに、ガイド溝３０に車両後方側で連通する溝状に設けられている。具体的には、係止溝４０は、ガイド溝底面３１と滑らかに連続する係止溝底面４１を有している。本実施形態において、係止溝底面４１とガイド溝底面３１とは面一である。したがって、一対のデッキサイドトリム２０，２０に設けられる係止溝底面４１，４１の間の寸法（車幅方向の距離）も、支持部材５０が車幅方向においてクリアランスを有して配置できる程度の大きさとされている。 The locking groove 40 fixes the locking portion (end) 52 of the support member 50. As shown in FIGS. 3 to 5, the locking groove 40 is recessed outward in the vehicle width direction from the inner surface 20A of the rear end portion 22, and is provided in a groove shape communicating with the guide groove 30 on the rear side of the vehicle. Specifically, the locking groove 40 has a locking groove bottom surface 41 that is smoothly continuous with the guide groove bottom surface 31. In the present embodiment, the bottom surface of the locking groove 41 and the bottom surface of the guide groove 31 are flush with each other. Therefore, the dimensions (distance in the vehicle width direction) between the locking groove bottom surfaces 41, 41 provided on the pair of deck side trims 20, 20 are also such that the support member 50 can be arranged with a clearance in the vehicle width direction. It is said to be the size.

また、係止溝４０は、係止溝底面４１から内面２０Ａに向けて立ち上がり前方を向く後方壁面４２と、係止溝底面４１の下端から立ち上がり上方を向く下方壁面４３と、係止溝底面４１の前方の端部から立ち上がり後方を向く前方壁面４４と、係止溝底面４１の上端から立ち上がり下方を向く上方壁面４５と、係止溝底面４１から立ち上がり下側壁面３３と上方壁面４５とを連絡する折返し壁面４６と、を有して構成されている。言い換えれば、係止溝４０は、内面２０Ａとこれらの壁面４２，４３，４４，４５，４６と係止溝底面４１とがそれぞれ段差状に構成されている。ガイド溝３０の上側壁面３２と、係止溝４０の後方壁面４２、下方壁面４３、前方壁面４４、上方壁面４５、および折返し壁面４６と、ガイド溝３０の下側壁面３３とは、この順に、互いの接続部において滑らかに連続する連続壁面を形成している。 Further, the locking groove 40 includes a rear wall surface 42 that rises from the bottom surface 41 of the locking groove toward the inner surface 20A and faces forward, a lower wall surface 43 that rises from the lower end of the bottom surface 41 of the locking groove and faces upward, and a bottom surface 41 of the locking groove. The front wall surface 44 that rises from the front end of the lock groove and faces backward, the upper wall surface 45 that rises from the upper end of the locking groove bottom surface 41 and faces downward, and the lower side wall surface 33 and the upper wall surface 45 that rise from the locking groove bottom surface 41 and face each other. It is configured to have a folded wall surface 46 and the like. In other words, in the locking groove 40, the inner surface 20A, the wall surfaces 42, 43, 44, 45, 46 and the locking groove bottom surface 41 are formed in a stepped shape, respectively. The upper wall surface 32 of the guide groove 30, the rear wall surface 42, the lower wall surface 43, the front wall surface 44, the upper wall surface 45, and the folded wall surface 46 of the locking groove 40, and the lower wall surface 33 of the guide groove 30 are arranged in this order. Smoothly continuous continuous wall surfaces are formed at the joints with each other.

ここで、係止溝４０は、車両後方に向かうにつれて下方に傾斜する傾斜部４０Ａと、傾斜部４０Ａの下端から車両前方に向かって略水平方向に延びる水平部４０Ｂとを含む。つまり、後方壁面４２と係止溝底面４１と折返し壁面４６とにより傾斜部４０Ａが構成されている。本実施形態において、後方壁面４２は、デッキサイドトリム２０の車両後方の縁部に沿うように傾斜されている。本実施形態のデッキサイドトリム２０の縁部、すなわち後方壁面４２は、水平方向に対して約３０°〜６０°（例えば４５°）の角度をなすように傾斜されている。なお、図４におけるＰ２は、後方壁面４２に沿ってその下端まで係止部５２を移動させたときの係止部５２の位置を示したものであり、Ｈ２は位置Ｐ２における係止部５２の高さを示す。 Here, the locking groove 40 includes an inclined portion 40A that inclines downward toward the rear of the vehicle, and a horizontal portion 40B that extends substantially horizontally from the lower end of the inclined portion 40A toward the front of the vehicle. That is, the inclined portion 40A is formed by the rear wall surface 42, the bottom surface 41 of the locking groove, and the folded wall surface 46. In the present embodiment, the rear wall surface 42 is inclined along the rear edge of the deck side trim 20 of the vehicle. The edge portion of the deck side trim 20 of the present embodiment, that is, the rear wall surface 42 is inclined so as to form an angle of about 30 ° to 60 ° (for example, 45 °) with respect to the horizontal direction. Note that P2 in FIG. 4 indicates the position of the locking portion 52 when the locking portion 52 is moved along the rear wall surface 42 to the lower end thereof, and H2 is the position of the locking portion 52 at the position P2. Indicates the height.

また、水平部４０Ｂは、係止溝底面４１と下方壁面４３と前方壁面４４と上方壁面４５とにより構成されている。下方壁面４３と前方壁面４４と上方壁面４５とは連続し、前方に向けて凹むコ字状壁を構成している。言い換えれば、係止溝４０は前方壁面４４において終端され、車両前方側で閉じられている。本実施形態の下方壁面４３は、略水平面を含むように配設されている。図４におけるＰ３は、コ字状壁に係止部５２の前方を挿入したときの係止部５２の位置を示したものであり、位置Ｐ３における係止部５２の高さは位置Ｐ２における高さと等しい。Ｈ２は、下方壁面４３に沿って係止部５２を移動したり、コ字状壁に係止部５２を挿入したりするときの係止部５２の高さでもある。高さＨ２は、上記の高さＨ１よりも低い。Ｈ３は、上方壁面４５のうちで最も高い位置を示す。高さＨ３は、上記の高さＨ１よりも低く、高さＨ２よりも高い。 Further, the horizontal portion 40B is composed of a locking groove bottom surface 41, a lower wall surface 43, a front wall surface 44, and an upper wall surface 45. The lower wall surface 43, the front wall surface 44, and the upper wall surface 45 form a U-shaped wall that is continuous and recesses toward the front. In other words, the locking groove 40 is terminated at the front wall surface 44 and closed on the front side of the vehicle. The lower wall surface 43 of the present embodiment is arranged so as to include a substantially horizontal plane. P3 in FIG. 4 indicates the position of the locking portion 52 when the front of the locking portion 52 is inserted into the U-shaped wall, and the height of the locking portion 52 at the position P3 is the height at the position P2. Is equal to. H2 is also the height of the locking portion 52 when the locking portion 52 is moved along the lower wall surface 43 or when the locking portion 52 is inserted into the U-shaped wall. The height H2 is lower than the above height H1. H3 indicates the highest position among the upper wall surface 45. The height H3 is lower than the above-mentioned height H1 and higher than the height H2.

この水平部４０Ｂにおいて、前方のコ字状壁の幅寸法（下方壁面４３と上方壁面４５との間の内寸）は、車両後方側（例えば、上方壁面４５のうちで最も高い位置）において支持部材５０の係止部５２の巻取側の端部５２ａの短手方向（ここでは上下方向）の寸法よりも大きく、車両前方の端部（すなわち、前方壁面４４の位置）に向かうにつれて狭くなっている。したがって、水平部４０Ｂは、傾斜部４０Ａより支持部材５０の係止部５２を導入できるように構成されている。例えば、下方壁面４３に沿って係止部５２を前方に移動させることで、係止部５２の前方をコ字状壁に挿入することができる。 In the horizontal portion 40B, the width dimension of the front U-shaped wall (inner dimension between the lower wall surface 43 and the upper wall surface 45) is supported on the rear side of the vehicle (for example, the highest position among the upper wall surface 45). It is larger than the dimension of the end portion 52a on the winding side of the locking portion 52 of the member 50 in the lateral direction (here, the vertical direction), and becomes narrower toward the end portion in front of the vehicle (that is, the position of the front wall surface 44). ing. Therefore, the horizontal portion 40B is configured so that the locking portion 52 of the support member 50 can be introduced from the inclined portion 40A. For example, by moving the locking portion 52 forward along the lower wall surface 43, the front of the locking portion 52 can be inserted into the U-shaped wall.

また、本実施形態の水平部４０Ｂのコ字状壁の幅寸法は、図４に示すように、車両前方の端部において当該係止部５２の巻取側の端部５２ａの短手方向の寸法よりも小さい。したがって、水平部４０Ｂに係止部５２が導入されると、少なくとも上方壁面４５および下方壁面４３が係止部５２の上方および下方にそれぞれ当接し、係止部５２が車両前方に向かって移動することを規制する。このことにより、水平部４０Ｂは支持部材５０を確実に係止可能な構成とされている。 Further, as shown in FIG. 4, the width dimension of the U-shaped wall of the horizontal portion 40B of the present embodiment is in the lateral direction of the winding-side end 52a of the locking portion 52 at the front end of the vehicle. Smaller than the dimensions. Therefore, when the locking portion 52 is introduced into the horizontal portion 40B, at least the upper wall surface 45 and the lower wall surface 43 come into contact with each other above and below the locking portion 52, and the locking portion 52 moves toward the front of the vehicle. Regulate that. As a result, the horizontal portion 40B is configured so that the support member 50 can be securely locked.

また、係止溝４０は傾斜部４０Ａと水平部４０Ｂとを有していることから、係止溝底面４１には傾斜部４０Ａの後方壁面４２と水平部４０Ｂの下方壁面４３との間に扇形の折曲領域Ｓが形成されている。そして本実施形態の係止溝４０は、図３および図４に示すように、デッキサイドトリム２０を車両１０のインナパネル（被取付部材）６０に固定するためのクリップ部材６２が取り付け可能に構成されている。このクリップ部材６２は、図６に示すように、大まかな構成として、頭部６２ａと脚部６２ｂとからなり、円板状の頭部６２ａの背面側の中心に脚部６２ｂが同軸に設けられている。そして係止溝底面４１には、このクリップ部材６２の頭部６２ａを収容するための車幅方向外側に凹んだクリップ凹部４７ａと、脚部６２ｂを挿通するための貫通孔４７ｂとが備えられている。クリップ凹部４７ａは、頭部６２ａよりも一回り大きい円形の凹部として形成されている。貫通孔４７ｂは、クリップ凹部４７ａと同心円状であって、脚部６２ｂの径より一回り大きくなるように形成されている。これらクリップ凹部４７ａと貫通孔４７ｂとによってクリップ部材６２の取付部４７が構成されている。このように、係止溝底面４１に備えられた円形の取付部４７の車両後方側には扇形の折曲領域Ｓが存在する。 Further, since the locking groove 40 has an inclined portion 40A and a horizontal portion 40B, the locking groove bottom surface 41 has a fan shape between the rear wall surface 42 of the inclined portion 40A and the lower wall surface 43 of the horizontal portion 40B. Bent region S is formed. As shown in FIGS. 3 and 4, the locking groove 40 of the present embodiment is configured so that a clip member 62 for fixing the deck side trim 20 to the inner panel (attached member) 60 of the vehicle 10 can be attached. Has been done. As shown in FIG. 6, the clip member 62 is composed of a head portion 62a and a leg portion 62b as a rough configuration, and the leg portion 62b is coaxially provided at the center on the back surface side of the disc-shaped head portion 62a. ing. The bottom surface 41 of the locking groove is provided with a clip recess 47a recessed outward in the vehicle width direction for accommodating the head portion 62a of the clip member 62, and a through hole 47b for inserting the leg portion 62b. There is. The clip recess 47a is formed as a circular recess that is one size larger than the head 62a. The through hole 47b is concentric with the clip recess 47a and is formed so as to be one size larger than the diameter of the leg portion 62b. The attachment portion 47 of the clip member 62 is formed by the clip recess 47a and the through hole 47b. As described above, the fan-shaped bent region S exists on the vehicle rear side of the circular mounting portion 47 provided on the bottom surface 41 of the locking groove.

以上のトノカバーの係止構造を備える車両１０において、トノカバーを使用（展設）するには、例えば、トノカバー前方係止部２３に架設されているトノカバー装置１４から支持部材５０を引き出し、トノカバー後方係止部２４に係止する。ここで、トノカバー後方係止部２４における係止構造は、支持部材５０の端部（係止部５２）を車両前後方向に沿って案内するガイド溝３０と、支持部材５０の端部を係止する係止溝４０とを備えており、係止溝４０は、ガイド溝３０に車両後方側で連通し車両後方に向かうにつれて下方に傾斜する傾斜部４０Ａと、傾斜部４０Ａの下端から車両前方に向かって略水平方向に延びる水平部４０Ｂとを備えた構成とされている。そして水平部４０Ｂは、その前方部分において、トノカバー（面状部材１４ｂ）を介して支持部材５０に加わる車両前方に向かう引張り力に抗して支持部材５０を係止可能な構成を備えている。 In order to use (extend) the tonneau cover in the vehicle 10 having the above tonneau cover locking structure, for example, the support member 50 is pulled out from the tonneau cover device 14 erected on the tonneau cover front locking portion 23, and the tonneau cover rear engagement is engaged. Locks to the stop 24. Here, the locking structure of the tonneau cover rear locking portion 24 locks the guide groove 30 that guides the end portion (locking portion 52) of the support member 50 along the vehicle front-rear direction and the end portion of the support member 50. The locking groove 40 is provided with a locking groove 40 that communicates with the guide groove 30 on the rear side of the vehicle and inclines downward toward the rear of the vehicle, and from the lower end of the inclined portion 40A to the front of the vehicle. It is configured to include a horizontal portion 40B extending in a substantially horizontal direction. The horizontal portion 40B has a configuration in which the support member 50 can be locked against the pulling force applied to the support member 50 toward the front of the vehicle via the tonneau cover (plane member 14b) in the front portion thereof.

上記構成によると、使用者は、支持部材５０を位置Ｐ３より上方で移動させながらガイド溝３０に導入することができ、支持部材５０を係止位置である位置Ｐ３よりも下方に移動させる必要がない。その結果、荷室１１に係止位置よりも上方にまで及ぶ大きな荷物や多量の荷物を収容している場合であっても、面状部材１４ｂで荷室１１を上方から覆うように支持部材５０を移動させながらスムーズに支持部材５０を係止溝４０に係止することができる。また、係止溝４０は、ガイド溝３０よりも車両後方側においては傾斜部４０Ａによって下方に傾斜し、その下端（位置Ｐ２）において水平部４０Ｂに接続されている。そのため、使用者は、ガイド溝３０から傾斜部４０Ａに沿って概ね車両後方に向かう一連の支持部材５０の移動によって支持部材５０をスムーズに水平部４０Ｂ（位置Ｐ２からＰ３）まで移動させることができる。 According to the above configuration, the user can introduce the support member 50 into the guide groove 30 while moving the support member 50 above the position P3, and it is necessary to move the support member 50 below the position P3 which is the locking position. No. As a result, even when the luggage compartment 11 accommodates a large luggage or a large amount of luggage extending above the locked position, the support member 50 so as to cover the luggage compartment 11 from above with the planar member 14b. The support member 50 can be smoothly locked in the locking groove 40 while moving the support member 50. Further, the locking groove 40 is inclined downward by the inclined portion 40A on the rear side of the vehicle with respect to the guide groove 30, and is connected to the horizontal portion 40B at the lower end (position P2) thereof. Therefore, the user can smoothly move the support member 50 from the guide groove 30 to the horizontal portion 40B (positions P2 to P3) by moving a series of support members 50 substantially toward the rear of the vehicle along the inclined portion 40A. ..

また、上記構成によると、使用者は、支持部材５０を水平部４０Ｂで車両前方に移動させることで、傾斜部４０Ａと水平部４０Ｂとにより構成される折返し形状によって、支持部材５０を水平部４０Ｂの前方部分にある係止位置に係止することができる。換言すれば、使用者は、支持部材を概ね車両後方に移動させる操作と、支持部材を水平部で前方に移動させる操作と、の２ステップでトノカバーを水平部４０Ｂの前方部分に位置する係止位置に容易に係止することができる。また、例えば、トノカバーが自動巻取り式であるとき等には、支持部材５０を傾斜部４０Ａの下端に移動させることで支持部材５０は面状部材１４ｂを介して自動的に車両前方に移動され、係止部５２がコ字状壁に係止される。これにより、１ステップでトノカバーを係止位置に容易に係止することができる。 Further, according to the above configuration, the user moves the support member 50 to the front of the vehicle by the horizontal portion 40B, so that the support member 50 is moved to the horizontal portion 40B by the folded shape formed by the inclined portion 40A and the horizontal portion 40B. It can be locked at the locking position in the front part of the. In other words, the user locks the tonneau cover located in the front part of the horizontal portion 40B in two steps, that is, the operation of moving the support member to the rear of the vehicle and the operation of moving the support member to the front in the horizontal portion. It can be easily locked to the position. Further, for example, when the tonneau cover is an automatic winding type, the support member 50 is automatically moved to the front of the vehicle via the planar member 14b by moving the support member 50 to the lower end of the inclined portion 40A. , The locking portion 52 is locked to the U-shaped wall. As a result, the tonneau cover can be easily locked to the locking position in one step.

上記構成によると、水平部４０Ｂは、コ字状壁によって車両前方側で閉じられている。また、コ字状壁の幅寸法は、車両後方側で係止部５２の巻取側の端部５２ａの上下方向の寸法よりも大きく、車両前方側で係止部５２の巻取側の端部５２ａよりも狭くなっている。これにより、コ字状壁は前方に向けて引っ張られる係止部５２を上方壁面４５と下方壁面４３とによって挟持することができる。このような構成により、車両が走行中に大きく振動した場合等でも、係止部５２をコ字状壁によって強固に固定することができる。また、コ字状壁の幅寸法は後方に向かうにつれ広くなるように形成されており、支持部材５０の係止部５２をコ字状壁に引き込み易いだけでなく、また、コ字状壁から係止部５２を引き抜き易いものとされている。 According to the above configuration, the horizontal portion 40B is closed on the front side of the vehicle by a U-shaped wall. Further, the width dimension of the U-shaped wall is larger than the vertical dimension of the winding-side end 52a of the locking portion 52 on the vehicle rear side, and the winding-side end of the locking portion 52 on the vehicle front side. It is narrower than the portion 52a. As a result, the U-shaped wall can sandwich the locking portion 52 that is pulled forward by the upper wall surface 45 and the lower wall surface 43. With such a configuration, the locking portion 52 can be firmly fixed by the U-shaped wall even when the vehicle vibrates significantly during traveling. Further, the width dimension of the U-shaped wall is formed so as to become wider toward the rear, and not only is it easy to pull the locking portion 52 of the support member 50 into the U-shaped wall, but also from the U-shaped wall. It is said that the locking portion 52 can be easily pulled out.

また、上記実施形態において、支持部材５０は棒状をなし、その両端部に係止溝４０に係止される係止部５２，５２を備えている。係止溝４０は、係止溝底面４１と、係止溝底面４１から立ち上がり下方を向く上方壁面４５と、係止溝底面４１の車両前方の端部から立ち上がり車両後方を向く前方壁面４４と、係止溝底面４１から立ち上がり、上方を向く下方壁面４３と、を備え、上方壁面４５、前方壁面４４、および下方壁面４３はコ字状壁を構成している。そして、少なくとも上方壁面４５および下方壁面４３は、支持部材５０の係止部５２の上方および下方にそれぞれ当接して支持部材５０を係止可能に構成されている。このような構成によると、水平部４０Ｂ支持部材の係止部の外形に対応するコ字状壁を備えており、トノカバーを介して支持部材に加わる車両前方に向かう引張り力に抗して、係止溝の水平部に支持部材を確実に係止することができる。 Further, in the above embodiment, the support member 50 has a rod shape and is provided with locking portions 52 and 52 locked in the locking grooves 40 at both ends thereof. The locking groove 40 includes a locking groove bottom surface 41, an upper wall surface 45 rising from the locking groove bottom surface 41 and facing downward, and a front wall surface 44 rising from the front end of the locking groove bottom surface 41 and facing the rear of the vehicle. A lower wall surface 43 rising from the bottom surface 41 of the locking groove and facing upward is provided, and the upper wall surface 45, the front wall surface 44, and the lower wall surface 43 form a U-shaped wall. At least the upper wall surface 45 and the lower wall surface 43 are configured to abut on the upper side and the lower side of the locking portion 52 of the support member 50 so that the support member 50 can be locked. According to such a configuration, a U-shaped wall corresponding to the outer shape of the locking portion of the horizontal portion 40B support member is provided, and the pulling force applied to the support member via the tonneau cover toward the front of the vehicle is resisted. The support member can be securely locked to the horizontal portion of the stop groove.

さらに、上記実施形態において、係止溝４０は係止溝底面４１を備えるとともに、傾斜部４０Ａにおいて係止溝底面４１から立ち上がり車両前方を向く後方壁面４２を備え、後方壁面４２は、デッキサイドトリム２０の車両後方の縁部に沿うように傾斜されている。このような構成において、デッキサイドトリム２０に備えられる係止溝４０の傾斜部４０Ａの外形は、デッキサイドトリム２０の車両後方の縁部の形状に沿うようにデザインされている。これにより、傾斜部４０Ａの外形とデッキサイドトリム２０の車両後方の縁部の形状とに統一感がもたらされ、デッキサイドトリムの意匠性が高められる。また、傾斜部４０Ａの外形がデッキサイドトリム２０の車両後方の縁部の形状に調和していることで、使用者がトノカバーを係止するとき、視覚的効果によって無意識のうちに、車両後方に移動させた支持部材５０を車両後方の縁部に沿って位置Ｐ２よりも下方にまで移動させる動作が促される。このことにより、使用者は、意図することなくトノカバーを傾斜部４０Ａの下端（位置Ｐ２）にまで移動させることができ、より一層スムーズに係止することができる。 Further, in the above embodiment, the locking groove 40 includes a locking groove bottom surface 41, and the inclined portion 40A includes a rear wall surface 42 that rises from the locking groove bottom surface 41 and faces the front of the vehicle, and the rear wall surface 42 is a deck side trim. It is tilted along the rear edge of the 20 vehicle. In such a configuration, the outer shape of the inclined portion 40A of the locking groove 40 provided in the deck side trim 20 is designed to follow the shape of the rear edge portion of the deck side trim 20 after the vehicle. As a result, the outer shape of the inclined portion 40A and the shape of the edge portion of the deck side trim 20 at the rear of the vehicle are unified, and the design of the deck side trim is enhanced. Further, since the outer shape of the inclined portion 40A is in harmony with the shape of the edge portion of the deck side trim 20 at the rear of the vehicle, when the user locks the tonneau cover, the user unknowingly moves to the rear of the vehicle due to a visual effect. The operation of moving the moved support member 50 along the rear edge of the vehicle to a position below the position P2 is promoted. As a result, the user can unintentionally move the tonneau cover to the lower end (position P2) of the inclined portion 40A, and can lock the tonneau cover even more smoothly.

また、上記実施形態において、ガイド溝３０と係止溝４０とは、底面（ガイド溝底面３１および係止溝底面４１）が面一の溝状に構成されており、底面は、デッキサイドトリム２０を車両１０のインナパネル（被取付部材）６０に固定するためのクリップ部材６２を取り付けるための取付部４７を備え、取付部４７は、傾斜部４０Ａと水平部４０Ｂとの間に形成される扇形の折曲領域Ｓの近傍に設けられている。このような構成によると、底面には、取付部４７よりも前方にガイド溝３０によるスペースが存在し、取付部４７よりも後方に折曲領域Ｓが存在する。そのため、クリップ部材６２の取付けに際し、この折曲領域Ｓを作業空間として利用することができる。具体的には、クリップ部材６２の頭部６２ａを把持した指をガイド溝３０によるスペースと折曲領域Ｓとに入れることができる。これにより、組付け作業者は、インナパネル（被取付部材）６０へのデッキサイドトリム２０の組付け作業を容易に行うことができる。 Further, in the above embodiment, the guide groove 30 and the locking groove 40 are configured such that the bottom surfaces (guide groove bottom surface 31 and locking groove bottom surface 41) are flush with each other, and the bottom surface is the deck side trim 20. A mounting portion 47 for mounting a clip member 62 for fixing the clip member 62 to the inner panel (mounted member) 60 of the vehicle 10 is provided, and the mounting portion 47 is a fan shape formed between the inclined portion 40A and the horizontal portion 40B. It is provided in the vicinity of the bending region S of. According to such a configuration, on the bottom surface, there is a space provided by the guide groove 30 in front of the mounting portion 47, and a bent region S exists behind the mounting portion 47. Therefore, when the clip member 62 is attached, the bent region S can be used as a work space. Specifically, the finger holding the head 62a of the clip member 62 can be inserted into the space provided by the guide groove 30 and the bent region S. As a result, the assembling worker can easily perform the assembling work of the deck side trim 20 to the inner panel (attached member) 60.

さらに、上記実施形態では、トノカバー後方係止部２４（ガイド溝３０および係止溝４０）の底面においてデッキサイドトリム２０がインナパネル（被取付部材）６０に固定されており、ガイド溝３０および係止溝４０は被取付部材に高い強度で組付けられている。その結果、使用者がトノカバーをガイド溝３０および係止溝４０に頻繁に係止したり、トノカバー装置１４から係止溝４０に負荷が加わったりしても、ガイド溝３０および係止溝４０の変形や破損が抑制される。これにより、耐久性に優れたトノカバーの係止構造が提供される。 Further, in the above embodiment, the deck side trim 20 is fixed to the inner panel (attached member) 60 on the bottom surface of the tonneau cover rear locking portion 24 (guide groove 30 and locking groove 40), and the guide groove 30 and the engaging member are engaged. The stop groove 40 is assembled to the member to be attached with high strength. As a result, even if the user frequently locks the tonneau cover to the guide groove 30 and the locking groove 40, or a load is applied to the locking groove 40 from the tonneau cover device 14, the tonneau cover 30 and the locking groove 40 Deformation and breakage are suppressed. This provides a tonneau cover locking structure with excellent durability.

なお、参考のために、図７に、従来のトノカバーの係止構造に係るトノカバー前方係止部１２３とトノカバー後方係止部１２４とを例示した。従来のトノカバーの係止構造において、トノカバー装置（図示せず）およびトノカバー前方係止部１２３の構成は上記実施形態と共通であるが、トノカバー後方係止部１２４の構成が上記実施形態とは異なる。従来のトノカバー後方係止部１２４においては、支持部材の係止部を後方係止部１２４に導入するときの高さＸ１が、係止部を係止する係止位置の高さＸ２よりも低い。そのため、図７中に矢印で示すように、使用者は、支持部材を係止位置（高さＸ２）よりも下方の係止位置（高さＸ１）より、さらに下方で移動させてトノカバー後方係止部１２４に導入する必要がある。そのため、荷室１１に導入高さＸ１よりも上方にまで及ぶ大きな荷物や多量の荷物を収容している場合には、支持部材を後方係止部１２４に係止し難くなっていた。とりわけ、後方係止部１２４の近傍で荷物の高さが導入高さＸ１近くに達する場合はその傾向が顕著となる。これに対し、本実施形態の係止構造は、このような不都合が生じない点において有利である。 For reference, FIG. 7 illustrates the tonneau cover front locking portion 123 and the tonneau cover rear locking portion 124 according to the conventional tonneau cover locking structure. In the conventional tonneau cover locking structure, the configuration of the tonneau cover device (not shown) and the tonneau cover front locking portion 123 is the same as the above embodiment, but the configuration of the tonneau cover rear locking portion 124 is different from the above embodiment. .. In the conventional tonneau cover rear locking portion 124, the height X1 when the locking portion of the support member is introduced into the rear locking portion 124 is lower than the height X2 of the locking position for locking the locking portion. .. Therefore, as shown by an arrow in FIG. 7, the user moves the support member further below the locking position (height X1) below the locking position (height X2) to engage the tonneau cover rear. It needs to be introduced into the stop 124. Therefore, when the luggage compartment 11 accommodates a large load or a large amount of load extending above the introduction height X1, it is difficult to lock the support member to the rear locking portion 124. In particular, when the height of the luggage reaches the introduction height X1 in the vicinity of the rear locking portion 124, this tendency becomes remarkable. On the other hand, the locking structure of the present embodiment is advantageous in that such inconvenience does not occur.

また、図８に、参考例としてのトノカバーの係止構造に係るトノカバー後方係止部２２４を例示した。参考例のトノカバーの係止構造においては、係止溝２４０が傾斜部４０Ａに代えて湾曲部２４０Ａを備える点において上記実施形態と相違し、その他（トノカバー装置、トノカバー前方係止部２２３、ガイド溝２３０、水平部２４０Ｂなど）の構成については共通している。湾曲部２４０Ａは、係止溝底面２４１と、係止溝底面２４１から内面２２０Ａに向けて立ち上がり前方を向く後方壁面２４２と、係止溝底面２４１から立ち上がり後方を向く折返し壁面２４６とにより構成されている。後方壁面２４２は垂直方向に直径を有する半円弧状をなしている。また水平部２４０Ｂは、係止溝底面２４１と、係止溝底面２４１から内面２２０Ａに向けて立ち上がり上方を向く下方壁面２４３と、係止溝底面２４１から立ち上がり後方を向く前方壁面２４４と、係止溝底面２４１から立ち上がり下方を向く上方壁面２４５とにより構成されている。下方壁面２４３と前方壁面２４４と上方壁面２４５とは連続し、前方に向けて凹むコ字状壁を構成している。このような係止構造において、後方壁面２４２に沿って支持部材を移動させたとき、最も車両後方となる位置Ｐ１１の高さはＹ１であり、後方壁面２４２の下端における高さであって係止位置Ｐ１２と等しい高さはＹ２であり、係止溝２４０における最後方位置よりも下端の方が、高さが低い。そして、上方壁面２４５のうちで最も高い位置（言い換えれば、コ字状壁の上端）の高さＹ３は、高さＹ１よりも低く、高さＹ２よりも高い。 Further, FIG. 8 illustrates a tonneau cover rear locking portion 224 related to a tonneau cover locking structure as a reference example. The tonneau cover locking structure of the reference example differs from the above embodiment in that the locking groove 240 includes a curved portion 240A instead of the inclined portion 40A, and other features (tonneau cover device, tonneau cover front locking portion 223, guide groove). The configurations of 230, horizontal portion 240B, etc.) are common. The curved portion 240A is composed of a locking groove bottom surface 241, a rear wall surface 242 that rises from the locking groove bottom surface 241 toward the inner surface 220A and faces forward, and a folded wall surface 246 that rises from the locking groove bottom surface 241 and faces rearward. There is. The rear wall surface 242 has a semicircular shape having a diameter in the vertical direction. Further, the horizontal portion 240B is locked with a locking groove bottom surface 241, a lower wall surface 243 that rises from the locking groove bottom surface 241 toward the inner surface 220A and faces upward, and a front wall surface 244 that rises from the locking groove bottom surface 241 and faces rearward. It is composed of an upper wall surface 245 that rises from the groove bottom surface 241 and faces downward. The lower wall surface 243, the front wall surface 244, and the upper wall surface 245 form a continuous U-shaped wall that is recessed toward the front. In such a locking structure, when the support member is moved along the rear wall surface 242, the height of the position P11 that is the rearmost to the vehicle is Y1, which is the height at the lower end of the rear wall surface 242 and is locked. The height equal to the position P12 is Y2, and the height at the lower end is lower than that at the rearmost position in the locking groove 240. The height Y3 at the highest position (in other words, the upper end of the U-shaped wall) of the upper wall surface 245 is lower than the height Y1 and higher than the height Y2.

このような参考例の係止構造によると、使用者がトノカバーを使用（展設）するとき、支持部材をガイド溝２３０から車両後方に向けて移動させるだけでは、後方壁面２４２の最後方の位置Ｐ１１（高さＹ１）までしか支持部材を移動させることができない。したがって、使用者は、位置Ｐ１１から後方壁面２４２の下端まで、支持部材を下方に向けて移動させる必要がある。ここで、後方壁面２４２は、最後方の位置Ｐ１１から下端に向かうにつれて前後方向の位置が前方に変化する。後方壁面２４２の前後方向の位置は、下端に向かうにつれてより大きく前方に変化する。したがって、使用者は、支持部材を後方壁面２４２の位置Ｐ１１から下端に移動させるために、支持部材を下方（一方向）に向けて移動させるだけでなく、後方壁面２４２の形状に合わせて支持部材を前方にも移動させる（前方への移動を許容する）必要がある。そして位置Ｐ１１よりも下方において、使用者が意識して支持部材を下方および前方に移動させない場合、支持部材は後方壁面２４２に沿って下端に到達できない。その結果、使用者が支持部材から手を離すと、支持部材がコ字状壁によって係止されず、巻取り装置によって巻き取られてしまうという事態が生じ得る。このような事態は、使用者が支持部材を位置Ｐ１１から、コ字状壁の上端の高さＹ３よりも十分に下方まで移動させなかった場合に生じ得る。これに対し、本実施形態の係止構造によると、概ね車両後方に向かう移動のみで支持部材５０を係止溝４０の下端にまでスムーズに移動させることができ、参考例におけるような不都合が生じない点において有利である。 According to the locking structure of such a reference example, when the user uses (extends) the tonneau cover, simply moving the support member from the guide groove 230 toward the rear of the vehicle is sufficient to move the support member toward the rear of the vehicle, which is the rearmost position of the rear wall surface 242. The support member can be moved only up to P11 (height Y1). Therefore, the user needs to move the support member downward from the position P11 to the lower end of the rear wall surface 242. Here, the position of the rear wall surface 242 in the front-rear direction changes forward from the rearmost position P11 toward the lower end. The position of the rear wall surface 242 in the front-rear direction changes more forward toward the lower end. Therefore, in order to move the support member from the position P11 of the rear wall surface 242 to the lower end, the user not only moves the support member downward (one direction) but also the support member according to the shape of the rear wall surface 242. Must also be moved forward (allowing forward movement). If the user does not consciously move the support member downward and forward below the position P11, the support member cannot reach the lower end along the rear wall surface 242. As a result, when the user releases the support member, the support member may not be locked by the U-shaped wall and may be wound by the winding device. Such a situation may occur when the user does not move the support member from position P11 sufficiently below the height Y3 of the upper end of the U-shaped wall. On the other hand, according to the locking structure of the present embodiment, the support member 50 can be smoothly moved to the lower end of the locking groove 40 only by moving toward the rear of the vehicle, which causes inconvenience as in the reference example. It is advantageous in that it does not exist.

また、参考例の係止構造によると、デッキサイドトリム２２０をインナパネルに固定するためのクリップ部材２６２の取付部２４７を係止溝２４０に備えると、係止溝底面２４１は取付部４７によって概ね占有されてしまう。したがって、デッキサイドトリム２２０をクリップ部材２６２によってインナパネルに固定するための取付作業が行いにくいという不都合が生じる。これに対し、本実施形態の係止構造によると、係止溝４０の下端まで傾斜部４０Ａが伸びていることから、傾斜部４０Ａと水平部４０Ｂとの間に折曲領域Ｓが形成される。したがって、この折曲領域Ｓをデッキサイドトリム２０の取付作業に利用することで、デッキサイドトリム２０の組み立てが容易になる点においても有利である。 Further, according to the locking structure of the reference example, when the locking groove 240 is provided with the mounting portion 247 of the clip member 262 for fixing the deck side trim 220 to the inner panel, the locking groove bottom surface 241 is generally provided by the mounting portion 47. It will be occupied. Therefore, there is a disadvantage that it is difficult to perform the mounting work for fixing the deck side trim 220 to the inner panel by the clip member 262. On the other hand, according to the locking structure of the present embodiment, since the inclined portion 40A extends to the lower end of the locking groove 40, the bent region S is formed between the inclined portion 40A and the horizontal portion 40B. .. Therefore, by using this bent region S for the mounting work of the deck side trim 20, it is also advantageous in that the deck side trim 20 can be easily assembled.

＜他の実施形態＞
本発明は上記記述及び図面によって説明した実施形態に限定されるものではなく、例えば次のような実施形態も本発明の技術的範囲に含まれ、さらに、下記以外にも要旨を逸脱しない範囲内で種々変更して実施することができる。 <Other embodiments>
The present invention is not limited to the embodiments described by the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention, and further, within the scope not deviating from the gist other than the following. It can be implemented with various changes.

（１）上記実施形態以外にも、トノカバーが配設される内装材は適宜変更可能である。上記実施形態では、トノカバーは、サイドトリムの上部に固定されるものとしたが、これに限られない。例えば、トノカバーは、エンドトリムやＤピラートリムに配設されるものであってもよい。 (1) In addition to the above embodiment, the interior material on which the tonneau cover is arranged can be changed as appropriate. In the above embodiment, the tonneau cover is fixed to the upper part of the side trim, but the present invention is not limited to this. For example, the tonneau cover may be arranged on the end trim or the D-pillar trim.

（２）上記実施形態において、トノカバー装置１４は巻取手段を備える自動巻取り式であったが、トノカバー装置１４の構成はこれに限定されず、巻取手段を備えないものであってもよい。また、面状部材１４ｂは略方形の布状であった。しかしながら、面状部材１４ｂの構成はこれに限定されず、例えば、網目状（ネット状）のものや、蛇腹状のもの、弾性変形するもの等を採用することもできる。 (2) In the above embodiment, the tonneau cover device 14 is an automatic winding type including a winding means, but the configuration of the tonneau cover device 14 is not limited to this, and may not be provided with a winding means. .. Further, the planar member 14b had a substantially square cloth shape. However, the configuration of the planar member 14b is not limited to this, and for example, a mesh-like (net-like) one, a bellows-like one, an elastically deformable one, or the like can be adopted.

（３）上記実施形態において、水平部４０Ｂにおけるコ字状壁の幅寸法は、車両後方側で係止部５２の巻取側の端部５２ａの上下方向の寸法よりも大きく、車両前方側で係止部５２の巻取側の端部５２ａよりも狭くなっていた。しかしながら、コ字状壁は前方に向けて閉じられていることにより支持部材５０の係止部５２を係止可能であるため、例えば、コ字状壁の幅寸法は車両前方側でも係止部５２の巻取側の端部５２ａより広くてもよい。 (3) In the above embodiment, the width dimension of the U-shaped wall in the horizontal portion 40B is larger than the vertical dimension of the end portion 52a on the winding side of the locking portion 52 on the rear side of the vehicle, and is on the front side of the vehicle. It was narrower than the winding-side end 52a of the locking portion 52. However, since the U-shaped wall is closed toward the front, the locking portion 52 of the support member 50 can be locked. Therefore, for example, the width dimension of the U-shaped wall is the locking portion even on the front side of the vehicle. It may be wider than the winding side end 52a of 52.
