Description

Technical Field

[0001] The present invention relates to a vehicle lamp that suppresses the movement of a cord disposed in a lamp chamber by a hook provided in the lamp chamber.

Background Art

[0002] In the lamp chamber of a vehicle lamp, a cord for connecting devices such as a light source unit and a sensor and transmitting signals and power is disposed. Since the cord may vibrate due to the vibration of the vehicle during running and may be damaged, it is desirable to prevent the cord from moving. For example, in Patent Document 1, a clamp is integrally provided at the lamp body opening to prevent the cord extending in the vertical direction from swaying left and right. Thus, the movement of the cord is suppressed without using a fixing member.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the clamp of Patent Document 1 is on the shortest path of the cord, and the cord is likely to come out. In addition, a pair of opposing latching pieces are formed in a small opening for connecting a ventilation pipe, and the cord is inserted and latched through the gap between the pair of latching pieces, so the cord is likely to come out. Also, a thick cord cannot be inserted through the gap, and a thin cord will come out of the gap. If the cord is movable, it is likely to be damaged and the function of the vehicle lamp cannot be exhibited. Therefore, a mode for restricting the movement of the cord is required.

[0005] The present invention has been made in view of the above problems, and provides a vehicle lamp that suppresses the movement of a cord disposed in a lamp chamber.

Means for Solving the Problems

[0006] To solve the above problem, a vehicle light fixture according to a first aspect of the present disclosure comprises a housing with an open front, a housing cover made of translucent resin attached to the front opening of the housing to form a light chamber, and a cord electrically connected to an electrical device arranged in the light chamber, wherein the rear wall of the housing is integrally formed with an opening that communicates with the outside and an L-shaped or J-shaped hook that protrudes toward the light chamber and secures the cord, and the hook is configured to be located at a position spaced apart from the shortest path of the cord.

[0007] Furthermore, in the vehicle lighting device of the second embodiment, the cord insertion point of the hook is configured to be located in the direction of the distance between the shortest path and the cord, as in the first embodiment.

[0008] Furthermore, in the vehicle lighting device of the third embodiment, a protrusion is formed near the hook for the cord to be secured, as in the first or second embodiment.

[0009] Furthermore, in the vehicle lighting device of the fourth embodiment, in any of the first to third embodiments, the protruding portion is a second hook arranged symmetrically with the hook.

[0010] Furthermore, in the vehicle lighting device of the fifth embodiment, in any of the first to fourth embodiments, a breathable sheet is attached to the outer surface of the housing in which the opening is provided. [Effects of the Invention]

[0013] Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The embodiments are illustrative and not limiting to the invention, and not all features or combinations thereof described in the embodiments are necessarily essential to the invention. Furthermore, in the following descriptions of embodiments and modifications, the same components will be denoted by the same reference numerals, and redundant descriptions will be omitted as appropriate.

[0014] (First Embodiment) FIG. 1 shows the arrangement state of the vehicle lamp 1 according to a preferred first embodiment of the present invention. It is a rear view of the vehicle V1 equipped with the vehicle lamp 1.

[0015] The vehicle lamp 1 is a seamless type rear combination lamp, and includes a tail lamp TALE that extends horizontally and long in the upper region, a pair of stop lamps STOP arranged in the left and right side regions below the tail lamp TALE, and a pair of turn signal lamps TURN arranged below the stop lamp. It is mounted on the rear of the vehicle V1 with the light irradiation direction facing backward.

[0016] A seamless type lamp is a lamp that presents an appearance that looks like one lamp so that the joint between the two independent lamps is not conspicuous when the two lamps are arranged side by side. The vehicle lamp 1 is composed of a pair of outside units OSU arranged on the outside in the vehicle width direction of the vehicle V1 and an inside unit ISU arranged in the rear trunk RT on the inside in the vehicle width direction. The outside unit OSU is provided with a tail lamp TALE, a stop lamp STOP, and a turn signal lamp TURN. Only the tail lamp TALE is provided in the inside unit ISU.

[0017] The tail lamp TALE is arranged in both the outside unit OSU and the inside unit ISU. By arranging the outside unit OSU and the inside unit ISU close to each other in the left - right direction, the tail lamp TALE is configured to present an appearance of one continuous lamp without a joint.

[0018] The tail lamp TALE is formed horizontally in a long single - character shape, and the vehicle lamp 1 is configured to be long in the vehicle width direction by this tail lamp TALE, and is arranged to occupy from the left - hand end to the right - hand end of the vehicle body.

[0019] Although the vehicle light fixture 1 is installed with its light emission direction facing the rear of the vehicle V1, in the following description of the vehicle light fixture 1, its light emission direction will be described as facing forward. The configuration of this disclosure is not limited to the rear lamps and tail lamps of this embodiment, but can also be used as headlights such as high-beam lamps, low-beam lamps, and fog lamps, and as marker lights such as high-mounted stop lamps, daytime running lamps, clearance lamps, side turn signal lamps, and automatic driving indicator lamps. Note that when the direction of light emission from the lamp is set to the front, the lamp is mounted to match the vehicle, such as being rotated 180 degrees relative to the vehicle as in the case of a rear lamp, so the direction of the vehicle and the direction of light emission from the lamp do not necessarily coincide.

[0020] Figure 2 is a cross-sectional view along the line II-II in Figure 1. As shown in Figure 2, the vehicle lamp 1 comprises a lamp body 2, which is a housing and is box-shaped with an open front, and a lamp cover 4, which is a housing cover and is made of translucent resin. The lamp cover 4 is welded to the front opening of the lamp body 2, forming a lamp chamber inside.

[0021] Inside the lamp chamber are the lamp unit LU and extension 5 for the taillights. The extension 5 is a concealing component that hides unnecessary parts. The mechanism and fixing parts of the lamp unit LU are shielded by the extension 5.

[0022] The lamp unit LU comprises a light guide 11 and a reflector 12. The light guide 11 is a rod-shaped optical element, with its longitudinal direction aligned with the extension direction (horizontal direction) of the lamp body 2. The front side of the light guide 11, along its longitudinal direction, is configured as an emission surface that emits light, and the rear side is configured as a reflective surface having multiple steps (not shown). Light incident on the light guide 11 travels through the light guide 11 while repeatedly undergoing total internal reflection, and light incident on the reflective surface (rear side) is reflected forward and emitted forward.

[0023] The reflector 12 is formed to be elongated in one direction and is approximately the same length as the light guide 11. Its longitudinal vertical cross-section is configured in a V-shape, and the light guide 11 is held in the central curved section. The inside of the reflector 12 is a reflective surface that reflects light and is configured to guide the light emitted from the light guide 11 forward. Light emitted upward or downward from the light guide 11 is reflected by the reflective surface on the inside of the reflector 12 and is projected forward as reflected light.

[0024] (Breathing holes and hooks) The hook 25 formed on the vehicle light fixture 1 will be described in detail. Figure 3 shows part A of Figure 1. Figure 3(A) is a front view, and Figure 3(B) is a perspective view. Part A is the central part of the inside unit ISU of the tail lamp TALE, which is configured to be long in the horizontal direction, of the vehicle light fixture 1. Figure 3 mainly shows the lamp body 2 and cord C1, and the lamp cover 4, lamp unit LU, etc. are omitted.

[0025] The rear wall 21, which is a structural surface facing the front opening of the lamp body 2, has breathing holes 23 and 24 formed therein to connect the inside and outside of the lamp chamber and circulate air inside and outside the lamp chamber.

[0026] These breathing holes allow for the expansion and contraction of air inside the lamp chamber due to heat generated by the light source and changes in temperature, while also allowing moisture inside the lamp chamber to escape to the outside, preventing moisture from accumulating inside. This prevents fogging inside the lamp chamber caused by moisture adhering to the lens and other parts from the inside of the lamp chamber.

[0027] The breathing holes 23 and 24 are rectangular through-holes, arranged in pairs vertically on the rear wall 21. A filter 9 is attached to the outer surface of the rear wall 21 of the lamp body 2, covering the pair of breathing holes 23 and 24. The filter 9 is a breathable sheet. By blocking the breathing holes 23 and 24 with the filter 9, dust and sand are blocked, while an air passage is maintained.

[0028] A hook 25 is formed in the lower breathing hole 24, which holds the cord C1. The hook 25 is a cord clamp that restricts the movement of the cord C1, and the cord C1 is hooked onto the hook 25, restricting its movement.

[0029] Code C1 is a wire harness that electrically connects to electrical / electronic equipment such as the light source unit and control unit of the lamp unit located inside the lamp chamber, transmitting electrical signals and power to them. The lamp body 2 is formed to be long in the horizontal direction, and Code C1, which is connected to the various units of the tail lamp TALE, also extends horizontally long inside the lamp chamber. Furthermore, Code C1 is positioned near the rear wall 21 so as not to interfere with the lamp unit LU that emits light, and so as not to be visible and detract from the design of the lamp fixture.

[0030] The hook 25 is formed to protrude into the lamp chamber from the rear wall 21, and has an inverted L-shape in cross-section. It protrudes horizontally from the rear wall 21 toward the inside of the lamp chamber, then bends 90 degrees downward and extends, with the opening that serves as the cord insertion point also located at the bottom. The lower breathing hole 24 and the hook 25 are integrally formed, and the rear end of the hook 25 is connected to the upper edge of the lower breathing hole 24. Unlike a normal hook that hooks from above, the hook 25 of this embodiment has an insertion point at the bottom and is structured to extend downwards to hook onto something above it.

[0031] (Mold) Figure 4 shows the mold 80 for the lamp body 2. This is a cross-sectional view taken at the position corresponding to line II-II in Figure 1. The mold 80 has a movable mold 81 and a fixed mold 82. When the movable mold 81 and the fixed mold 82 are positioned facing each other and clamped together, a molding space (cavitation) S1 corresponding to the shape of the lamp body 2 is defined inside the mold 80. Molten resin is injected and filled into the cavitation S1, and the lamp body 2 is molded by cooling and solidifying.

[0032] The hook 25 is configured such that its protruding portion overlaps the breathing hole 24 when viewed from the front of the lamp body 2. The demolding direction DR is set along the horizontal plane of the L-shape of the hook 25, and a boundary (parting line) is provided along the inner surface of the L-shape. The protrusion 81a of the movable mold 81 for forming the hook 25 is provided protruding from the portion corresponding to the breathing hole 24. When the mold 80 is opened, the movable mold 81, including the protrusion 81a, moves in the demolding direction DR and separates from the fixed mold 82 without any problems.

[0033] The hook 25 is formed using the breathing hole 24, which is an opening formed in the rear wall 21 of the lamp body 2. By integrally forming the hook 25 with the breathing hole 24, the hook 25 and the breathing hole 24 can be formed without creating an undercut in the mold 80 of the lamp body 2.

[0034] Conventionally, the movement of cords is restricted by using fixing members such as cable ties, but this has the problem of being time-consuming because the fixing member must be removed and wrapped around the cord when attaching it. With the configuration disclosed herein, the movement of cord C1 can be easily restricted simply by hooking the cord C1 onto the hook 25.

[0035] (Protruding part for locking) As shown in Figure 3, the rear wall 21 has protrusions 28 and 29 that project toward the lamp interior. The protrusions 28 and 29 are for positioning the cord C1 in a predetermined location and serve as locking points for the cord C1.

[0036] The protrusions 28 and 29 are provided in pairs in the left-right direction, flanking the hook 25. In the up-down direction, the protrusions 28 and 29 are formed at the same height as the hook 25, but at a higher position.

[0037] The protrusions 28 and 29 are elongated rectangles in the horizontal direction, and the cord C1 is placed on their upper surfaces and wired. The hook 25 is formed below the pair of protrusions 28 and 29, and the cord C1 protrudes downward from between the protrusions 28 and 29 and is hooked onto the hook 25. The cord C1 is alternately secured in the vertical direction by the protrusions 28, hook 25, and protrusions 29, and is wired in a wave pattern. As a result, the movement of the cord C1 in the vertical direction is firmly restricted.

[0038] (Effects and Benefits) The effects of this configuration will be explained using Figure 5. Figure 5 is an explanatory diagram illustrating the effects of this configuration. Other components are omitted as appropriate, as the explanation will mainly focus on the wiring of the cord. Figure 5(A) shows a comparative configuration, showing a lamp body 902 in which no hook is formed in the opening. Figure 5(B) shows the current configuration, showing a lamp body 2 in which the hook 25 is formed.

[0039] As shown in Figure 5(A), the rear wall 921 of the ramp body 902 has breathing holes 923 and 924, which are openings, but no hooks. Therefore, the cord C901 is positioned continuously on the upper surface of two protrusions 928 and 929 that are aligned in the left-right direction. The cord C901 positioned on the ramp body 901 rests on the upper surface of the protrusions 929, and its movement in the front-rear and upward directions is not restricted. Therefore, when the vehicle on which the ramp body 902 is mounted moves, the cord C902 also vibrates, and there is a concern that it may be damaged or broken by rubbing or hitting its corners.

[0040] In contrast, as shown in Figure 5(B), in this configuration, a hook 25 is formed integrally with the breathing hole 23 on the rear wall 21 of the lamp body 2, below the pair of protrusions 29, 29. The hook 25 is formed facing downward at a position offset by a predetermined distance L1 below the shortest path VL1 of the code in the absence of the hook 25, i.e., the path of code C902 (shown by the dashed line in Figure 5(B) and corresponding to the dotted line in Figure 5(A)).

[0041] A hook 25 is provided at a position separated downward (white arrow) from the shortest path VL1. When the cord C1 is actually hooked onto the hook 25, tension is applied to the cord C1 upward (black arrow) towards its original position. By being hooked onto the hook 25, the vertical movement of the cord C1 is restricted. Since the cord insertion point of the hook 25 is formed downward (white arrow) in the direction separated from the shortest path VL1, the movement of the cord C1 is firmly restricted.

[0042] In addition, in the front-to-back direction, the movement of code C1 is also restricted because it is positioned between the vertical plane of the L-shaped hook 25 and the rear wall 21 (see Figure 2). The movement of code C1 is strongly restricted by the hook 25.

[0043] (How to attach the cord) The installer of code C1 first connects the male connector 3 located at the right end of code C1 to the female connector 14 located at the lower edge of the circuit board 13 and secures it. The other unsecured end of code C1 is then placed over a nearby protrusion 29 from above, and the code C1 is routed along the top surface of the protrusion 29. Next, code C1 is placed between protrusions 28 and 29 and hooked onto the hook 25 from below. Code C1 is then pulled up and placed over the other protrusion 29, and finally the connector (not shown) located at the left end is fitted into place. Code C1 is routed sequentially over the protrusions 29 and hook 25 in an alternating pattern in the vertical direction, and is ultimately wired in a wavy pattern, firmly restricting its movement in the vertical direction.

[0044] Thus, when attaching the cord, it is preferable to fix the connector provided at one end, then sequentially position the free end of the cord C1 toward the other end and hook it onto the hook, and finally fit and fix the connector provided at the other end. This allows for easy restriction of movement in all directions. Furthermore, it is preferable to adjust the length of the cord C1 during the design stage so that the cord C1 can be routed without difficulty.

[0045] (modified version) This configuration is not limited to the above embodiment. A modified example is shown in Figure 6. Figure 6(A) is a cross-sectional view of the lamp body 2A on which the J-shaped hook 25A is formed. Figure 6(A) corresponds to Figure 2. Figure 6(B) is a cross-sectional view of the mold 80A of the lamp body 2A. Figure 6(B) corresponds to Figure 4.

[0046] As shown in Figure 6, a horizontally oriented J-shaped hook 25A is formed on the rear wall 21A of the lamp body 2A, protruding toward the lamp chamber. The rear end of the hook 25A is connected to the upper edge of the breathing hole 24, from which it protrudes into the lamp chamber, then bends downward at a 90-degree angle, and then bends backward at a further 90-degree angle, extending slightly. The horizontal surface at the tip acts as a return, making it difficult for the cord C1 to come loose from the hook 25A.

[0047] As shown in Figure 6(B), the mold 80A for the lamp body 2A comprises a movable mold 81A and a fixed mold 82A. When the movable mold 81A and the fixed mold 82A are positioned facing each other and clamped together, a molding space (cavitation) S1A corresponding to the shape of the lamp body 2A is defined inside the mold 80. Molten resin is injected and filled into the cavitation S1A, and the lamp body 2A is molded by cooling and solidifying.

[0048] The demolding direction DR is set along the horizontal plane of the hook 25A. The horizontal plane of the base end of the hook 25A and the horizontal plane of the tip end that forms the return are parallel, and the extension direction coincides with the demolding direction DR. A boundary (parting line) is provided corresponding to the inner surface of the J-shape of the hook 25A, and the protrusion 81aA of the moving mold 81A for forming the hook 25A is provided to protrude to the part corresponding to the breathing hole 24A when the mold 80A opens. Therefore, when the mold opens, the moving mold 81A including the protrusion 81aA can move in the demolding direction DR without any problems and separate from the fixed mold 82A. Even if the shape of the hook 25A is J-shaped, the ramp body 2A can be molded without creating an undercut in the mold 80A. Thus, the cross-sectional shape of the hook integrally formed in the opening is not limited to an L-shape (including an inverted L-shape), but may also be a J-shape (including an inverted J-shape).

[0049] Furthermore, the opening in the lamp body 2 into which the hook 25 is integrally formed is not limited to the breathing hole 24, but may also be a mounting hole for a part or a notch. As long as it is an opening that communicates with the outside and can form a hook without impairing its original function as an opening, the type of opening into which the hook is integrally formed is not limited.

[0050] Furthermore, in this embodiment, the hook 25 has an insertion point in a direction away from the optimal path VL1 (downward). An upward force is applied to the cord C1 hooked on the hook 25, but this is in the direction opposite to the downward insertion point, which is the direction in which the cord C1 would come off the hook 25. Therefore, the cord C1 is least likely to come off and is most securely fastened. Thus, it is preferable to provide the insertion point of the hook so that it coincides with the direction in which the hook moves away from the optimal path VL1. However, it is not limited to this, and the direction of the cord insertion point of the hook may be any direction other than the opposite direction of the separation direction, that intersects the optimal path VL1.

[0051] (Second Embodiment) Figure 8 shows a vehicle lighting fixture 201 according to the second embodiment. Figure 7 corresponds to Figure 3(B). Primarily, the lamp body 202 and code C2 of the vehicle lighting fixture 201 are shown, and other components are omitted as appropriate.

[0052] The vehicle lighting fixture 101 comprises a lamp body 102 with an open front and a lamp cover 104 (not shown). The lamp cover 104 is attached to the front opening of the lamp body 102, forming a lamp chamber inside. A cord C2, which electrically connects the components of the lamp unit, is located inside the lamp chamber.

[0053] The rear wall 121 of the lamp body 102 has breathing holes 123 and 124 formed therein, which serve as openings to communicate with the outside. Both breathing holes 123 and 124 are rectangular in shape and are arranged in pairs side by side in the left-right direction. A filter 9 (not shown) is attached to the outer surface of the rear wall 121, covering the breathing holes 123 and 124.

[0054] An upward-facing hook 125 for securing the cord C2 is integrally formed with the left breathing hole 123. Similarly, a downward-facing second hook 126 for securing the cord C2 is integrally formed with the right breathing hole 124.

[0055] The rear end of the hook 125 is connected to the lower edge of the breathing hole 123, and it extends horizontally from the rear wall 121 toward the lamp chamber, then bends upward at a 90-degree angle to form an L-shape. In contrast, the rear end of the second hook 126 is connected to the upper edge of the breathing hole 124, and it extends horizontally from the rear wall 121 toward the lamp chamber, then bends downward at a 90-degree angle to form an inverted L-shape.

[0056] Hook 125 and the second hook 126 are cord clamps, and the cord C2 is hooked onto hook 125 and the second hook 126 to restrict its movement.

[0057] The hook 125 and the second hook 126 are similar in form to the hook 25 and are integrally formed with the breathing holes 123 and 124, which are openings in the rear wall 121, so that they can be molded without creating undercuts in the mold.

[0058] A male connector 103 is provided at the left end of cord C2, and it is fitted and fixed to a female connector 114 provided at the lower end of the circuit board 113. The female connector 114 is located near the bottom surface of the lamp body 102, and the locking point of cord C2 is near the floor surface. Therefore, the shortest path VL2 of the cord in the lamp body 102 (shown as a dotted line in Figure 8, the wiring of cord C2' that is not hooked to hook 125 and the second hook 126) extends parallel to the bottom surface of the lamp body 102.

[0059] In this embodiment, a hook 125 is formed on the rear wall 21 of the lamp body 102 at a position offset upward by a predetermined distance L2 from the shortest path VL2 (the path of code C2'). The hook 125 is L-shaped, with the insertion opening facing upward.

[0060] When code C2 is hooked onto hook 125, it is hooked in a roundabout way, moving upward away from the shortest path VL2, which is the path of code C2', and tension is applied downward in the direction of the shortest path VL2, which is its original position. This restricts the vertical movement of code C2. Furthermore, it is clamped between the vertical plane and the rear wall 121 of hook 125, restricting its movement in the front-to-back direction as well. Hook 125 restricts the movement of code C2 in all directions.

[0061] In addition, in this embodiment, a second hook 126 is formed. The pair of hooks 125, which are formed in opposite directions, are hooked onto the second hook 126, further restricting the vertical movement of the cord C2.

[0062] The second hook 126 is a locking part that secures the cord C2 and functions the same as the protrusions 28 and 29. A hook of this configuration may be used as a locking part that secures the cord.

[0063] Furthermore, the restriction of cord movement by hooks is not limited to one direction; a single hook may be configured to restrict movement in two directions by offsetting it from the shortest path.

[0064] (Third embodiment) Figure 9 is a rear view of the left rear of a vehicle V2 equipped with a vehicle light fixture 201 according to a preferred third embodiment of the present invention.

[0065] The vehicle lighting fixture 201 is a rear combination lamp consisting of a turn signal lamp TURN2, a stop lamp STOP2, and a reverse lamp BACK2, and is installed in pairs on the left and right rear ends of the vehicle V2.

[0066] Each lamp is roughly the same size and arranged in a nearly square shape. The upper area of ​​the vehicle lighting fixture 201 is configured as the turn signal lamp TURN2, the central area as the stop lamp STOP2, and the lower area as the reverse lamp BACK2. Because the three lamps are arranged vertically, the vehicle lighting fixture 201 has a vertically elongated structure.

[0067] The vehicle lighting fixture 201 has a lamp body 202 with an open front as its housing, and a lamp cover 204 is attached to the front opening of the lamp body 202, thereby defining a lamp chamber inside. The lamp chamber houses the three lamp units and the cord C3 that connects to these devices.

[0068] Figure 10 shows a portion of the lamp body 202. The vertically elongated lamp body 202 has been cut out from its central vertical section, corresponding to the external shape of the vehicle light fixture 201. Other parts are omitted as appropriate, as the figure primarily shows the lamp body 202 and code C3.

[0069] The rear wall 221 of the lamp body 202 is provided with a pair of rectangular breathing holes 223 and 224, arranged side by side in the left-right direction, which are intended to connect the inside and outside of the lamp chamber and circulate air between the inside and outside of the lamp chamber.

[0070] A hook 225 is formed in the right-hand breathing hole 224, into which the cord C3 is attached. The hook 225 is a cord clamp that restricts the movement of the cord C3, which extends in the vertical direction, and the cord C3 is attached to the hook 225, restricting its movement.

[0071] The hook 225 is integrally formed with the breathing hole 224 on the rear wall 221, and the rear end of the hook 225 is connected to the left edge of the breathing hole 224. When viewed from above, the hook 225 has an L-shape, protruding horizontally from the rear wall 221 toward the interior of the lamp, then bending 90 degrees to the right and extending, with the cord insertion point also on the right side.

[0072] Code C3 is positioned to extend vertically, corresponding to the vertically elongated vehicle light fixture 201. On the rear wall 221, protrusions 228 and 229 are formed vertically, flanking the hook 225 and breathing holes 223 and 224, projecting toward the light interior. The protrusions 228 and 229 are for positioning code C3 in place and are configured as vertically elongated rectangles, with code C3 routed along their left side.

[0073] Hook 225 is formed to the right of the left side of projections 228 and 229. Using this, cord C3 is hooked onto hook 225 from the right and positioned along the left side of projections 28 and 29. Cord C3 is alternately hooked onto projections 228, hook 225, and projections 229 in the left-right direction and wired in a wave pattern. As a result, the movement of cord C3 is firmly restricted.

[0074] In the lamp body 302, the code C3', which is arranged along the shortest path, is shown by a dotted line in accordance with Figure 10. In this embodiment, the hook 225 is formed at a position spaced to the right of the shortest path VL3, with its insertion point facing to the right.

[0075] When the cord C3 is hooked onto the hook 225 located to the right of the shortest path VL3, tension is applied to the cord C3, causing it to move to the left and restricting its lateral movement. Furthermore, the cord C3 is sandwiched between the vertical plane and the rear wall 221 of the hook 225, restricting its forward and backward movement as well. By being hooked onto the hook 225, the movement of the cord C3 is firmly restricted.

[0076] Thus, since the structure of the hook that secures the cord is determined by the direction of cord extension, the offset direction of the hook, and the direction of the insertion point, it can be used not only to restrict the cord's movement in the vertical direction, but also to restrict movement in the horizontal direction as well as the forward and backward directions.

[0077] The embodiments described above are examples of the present invention, and these can be combined based on the knowledge of those skilled in the art; such combinations are also included within the scope of the present invention. [Explanation of Symbols]
