Description

  The present invention relates to a wheel stopper that functions as a stopper by interfering with a wheel.

  This type of wheel stopper is frequently used as a car stopper in a parking lot or the like, and various structures have been proposed (for example, Patent Document 1).

JP-A-11-278224

  In this patent document, the mounting portion on which the wheel is mounted is integrated with the wheel interference portion, and these are made hollow, and the hollow portion is filled with a honeycomb material to reduce the weight. However, since the wheel stopper needs to be transported and installed manually, it is necessary to further reduce the weight to reduce the work load while ensuring the strength to withstand practical use as a wheel stopper. It came.

  The present invention has been made to solve at least a part of the above-described conventional problems, and an object of the present invention is to provide a new wheel stopper that achieves both weight reduction and strength securing.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the following configuration is adopted.

[Application 1: Wheel stopper]
A wheel stopper,
A base installed on the floor,
A stopper portion that rises upward from the base in a convex shape with a bottom that opens on the floor surface side;
The stopper portion has the bottomed portion as a top, and the first side wall from the top to the base is a wheel interference portion that performs a stopper function, and the first side wall itself has a plurality of ridges on the first side wall. Then, the first side wall, the second side wall facing the first side wall, and the third side wall extending from the first side wall to the second side wall on the width direction end portion side of the first side wall and facing each other. Making the convex shape,
The base includes the end of the first side wall and the end of the third side wall facing each other, and surrounds the stopper portion.

  In the wheel stopper having the above configuration, the stopper portion is raised upward from the base installed on the floor surface, and the first side wall in the stopper portion reaches the base from the top with the bottomed portion as the top, It becomes a wheel interference part that performs the stopper function. The wheel stopper having the above-described configuration extends from the first side wall to the second side wall on the first side wall serving as a wheel interference part, the second side wall facing the first side wall, and the width direction end portion side of the first side wall. The stopper portion has a convex shape with the opposing third side wall to ensure the strength of the stopper portion, and the first side wall has a plurality of ridges, and the first side wall of the stopper portion itself has these ridges. It shall be raised. Therefore, in the wheel stopper having the above-described configuration, the strength of the first side wall which is a convex side wall and serves as a wheel interference portion is increased by a plurality of ridges provided on the first side wall. The stopper includes a base including an end of the first side wall and an end of the third side wall that extends from the first side wall to the second side wall on the width direction end side of the first side wall. The stopper portion can be reinforced at the opening by this base. As a result, according to the wheel stopper having the above-described structure, it is not necessary to use another member for reinforcing the stopper portion having a bottomed convex shape, so that the weight can be reduced and the first side wall of the stopper portion can be achieved. This strength can be ensured for practical use by reinforcing with a plurality of raised ridges and a base. In this case, since the wheel stopper having the above-described structure raises the bottomed stopper portion from the base and raises the first side wall itself of the ridge, it follows the inner and outer wall surface shapes of the convex stopper portion. It can be easily manufactured and cost can be reduced by press molding of a steel plate with a metal mold or resin molding. In this case, each of the plurality of ridges in the stopper portion can be extended in the width direction of the first side wall to be parallel.

  The wheel stopper described above can be configured as follows. For example, one of the plurality of ridges extending in the width direction of the first side wall and parallel thereto may be positioned at the base of the first side wall rising from the base. If it carries out like this, the protrusion of the base side of a 1st side wall (henceforth, base side protrusion) contact | abuts a wheel, before a wheel interferes with the 1st side wall of a stopper part. For this reason, since the vehicle operator can perceive that a wheel will interfere with a 1st side wall by the wheel contact | abutting to a base side convex item | strip | ridge, the stop operation through subsequent brake operation becomes simple.

  In addition, the stopper portion is hung from the top to the end of the second side wall on the second side wall facing the first side wall so as to be convex toward the first side wall. Can have. If it carries out like this, since it can reinforce also about a 2nd side wall in a recessed part, the intensity | strength of a stopper part can be raised further.

  Further, a reinforcing material incorporated from the opening of the stopper portion is provided, and this reinforcing material extends from the end of the second side wall to the top and is joined to the inner wall surface of the second side wall. A plate-shaped first material that is joined to the first material, extends from the first material toward the first side wall, and contacts the inner wall surface of the first side wall and the inner wall surface of the top, respectively. And a second material having a shape. By doing so, the stopper portion can be reinforced from the inside thereof, so that the strength can be further improved. In this case, since the reinforcing material is only a plate material, weight reduction can be prevented. Then, the first material in the reinforcing material is bent and formed so as to surround the recess of the second side wall with the first material, and then the second material is attached to both ends of the first material. If it is provided on the side, the reinforcement from the inside of the stopper portion is ensured and the displacement of the reinforcing material can be suppressed.

  In addition, if the end portion of the second side wall in the stopper portion is extended from the base and the end portion is an uneven end portion having continuous unevenness, the uneven end portion is in contact with the floor surface. , The wheel stopper displacement can be suppressed.

  Embodiments of the present invention will be described below with reference to the drawings. First, a wheel stopper 100 of a reference example that is a premise of the wheel stopper 10 of the present embodiment will be described. FIG. 1 is a perspective view of a wheel stopper 100 of a reference example as viewed from the front upper side thereof, FIG. 2 is a front view of the wheel stopper 100, FIG. 3 is a right side view of the wheel stopper 100, and FIG. 5 is a bottom view of the wheel stopper 100, FIG. 6 is a rear view of the wheel stopper 100, FIG. 7 is a perspective view of the wheel stopper 100 as viewed from above the back, and FIG. 8 is a cutaway view of the wheel stopper 100 at the front center. It is a schematic sectional drawing shown. In this case, the left side view of the wheel stopper 100 appears symmetrically with the right side view. Further, in the perspective views of FIG. 1 to FIG. 7, the thin lines written in parallel in the drawing in the horizontal, vertical, or diagonal directions, and the thin lines written in parallel in a curved line are lines representing the shadow of the surface. is there.

  As shown in these drawings, the wheel stopper 100 includes a base 120 and a stopper portion 140. The base 120 has a flat plate shape and is installed on a floor surface corresponding to the xy plane shown in the drawing. As shown in the sectional end view of FIG. 8, the stopper portion 140 has a bottomed convex shape opened on the floor surface side, rises upward from the base 120, and extends in the illustrated z direction in the vertical direction. . The stopper portion 140 has a convex bottomed portion 150 as a top, and a first side wall 160 extending from the bottomed portion 150 to the base 120 serves as a wheel interference portion that performs a stopper function. The second side wall 180 facing each other and the third side walls 200R and 200L extending from the first side wall 160 to the second side wall 180 and facing each other on the width direction end portion side of the first side wall 160 form a convex shape. In addition, the stopper part 140 rising from the base 120 is provided with a ridge 220 at the base part of the first side wall 160, in which the first side wall 160 of the base part rises and extends in the width direction of the first side wall 160. The ridge 220 has an upper surface that is parallel to the base 120 and extends toward the base 120. In this case, the width direction of the first side wall 160 is the wheel width direction when the wheel stopper 100 is used.

  The base 120 includes base edges 120R and 120L extending to the opposing third side wall 200R and the third side wall 200L, and a third edge facing the end of the first side wall 160 at the left and right edges. Including the side wall 200R and the end of the third side wall 200L, the stopper portion 140 is surrounded on three sides around the opening. And the base 120 is provided with the through-hole 130 for the anchor bolt etc. for floor surface fixation in the front end side and base edge part 120R, 120L in FIG. In this case, as shown in the sectional end view of FIG. 8, the base 120 is projected in a flat plate shape toward the stopper portion 140 in the region surrounded by the end edge where the through hole 130 is provided.

  The ridge 220 is provided at the base of the first side wall 160 as described above. Therefore, when a wheel (not shown) rolls from the base 120 side, the wheel comes into contact with the ridge 220 before interfering with the first side wall 160 of the stopper portion 140.

  In addition, the stopper part 140 includes a recess 240 that is recessed toward the first side wall 160 on the second side wall 180 that faces the first side wall 160. The recess 240 extends from the bottomed portion 150 to the end of the second side wall 180 at the center of the second side wall 180.

  Further, as shown in the front view of FIG. 2, the side view of FIG. 3, the rear view of FIG. 6, and the schematic cross-sectional view of FIG. 8, the stopper portion 140 has the end portion 250 of the second side wall 180 as the bottom surface of the base 120. Is longer than About this edge part 250, it can be made into the edge part of a flat end surface, and can also be performed as follows. FIG. 9 is an explanatory diagram showing an enlarged part of the end 250 in FIG. As shown in the drawing, the end 250 of the second side wall 180 can be an uneven end having continuous unevenness. And if the edge part 250 is extended rather than the bottom face of the base 120 in this way and it is set as an uneven | corrugated edge part, the shift | offset | difference of the wheel stopper 10 can be suppressed because the edge part 250 of an uneven | corrugated edge part contacts a floor surface. The wheel stopper 100 has a rising height of the stopper portion 140 that is larger in each step than the thickness of the thin steel plate used for forming the wheel stopper 100. Therefore, in the schematic cross-sectional view of FIG. The side wall 160, the ridge 220 of the side wall, the bottomed portion 150, and the recess 240 are drawn in cross section, and the second side wall 180 and the end portion 250 are drawn in outline.

  The wheel stopper 10 of the present embodiment has the following configuration after following the structure of the wheel stopper 100 of the reference example described above. In addition, about the member same as the wheel stopper 100 of said reference example, the description is abbreviate | omitted using the same code | symbol. 10 is a perspective view of the wheel stopper 10 according to the embodiment as viewed from above the front, FIG. 11 is a front view of the wheel stopper 10, FIG. 12 is a right side view of the wheel stopper 10, and FIG. 13 is a plan view of the wheel stopper 10. 14 is a bottom view of the wheel stopper 10, FIG. 15 is a rear view of the wheel stopper 10, FIG. 16 is a perspective view of the wheel stopper 10 as viewed from above the back, and FIG. 17 is a cutaway view of the wheel stopper 10 at the center of the front. It is a schematic sectional drawing shown. In this case, the left side view of the wheel stopper 10 appears symmetrically with the right side view. Further, in the perspective views of FIG. 10 to FIG. 16, the thin lines drawn in parallel horizontally or vertically or diagonally in the figure, and the thin lines written in parallel in a curved line are lines representing the shadow of the surface. is there.

  As shown in these figures, even in the wheel stopper 10 of the present embodiment, as in the wheel stopper 100 described above, the stopper portion 140 is raised from the flat base 120 and installed on the floor surface. . The wheel stopper 10 according to the present embodiment includes, on the first side wall 160 of the stopper portion 140, a ridge 220 with a raised first side wall itself at the side wall base, and the width of the first side wall 160 parallel to the ridge. A first small ridge 222 and a second small ridge 224 extending in the direction are provided. The width direction of the first side wall 160 is the width direction of the wheel when the wheel stopper 10 is used.

  The wheel stopper 10 of the present embodiment surrounds the stopper portion 140 in three directions around the opening as already described in the base 120, and the wheel protrusions 122 for preventing wheel slip are disposed on the upper surface of the base 120. Prepare. The circular protrusion 122 functions to prevent slipping of the wheel riding on the base 120, and the scattered state can be striped or can be a logo mark desired by the user of the wheel stopper 10. . In the latter case, the circular protrusion 122 functions as a name plate for distinguishing users, a so-called name plate.

  The wheel stopper 10 of the present embodiment includes a first side wall 160 that rises from the base 120, and has a ridge 220, a first small ridge 222, and a second small ridge 224 that are protruded from the base side. The first small ridge 222 and the second small ridge 224 are ridges in which a part of the first side wall 160 is raised in an arc shape. In this case, even in the wheel stopper 10, since the rising height of the stopper portion 140 is larger in each step than the thickness of the thin steel plate used for forming the wheel stopper 10, in the schematic sectional view of FIG. 120, the first side wall 160, the ridges 220, the first small ridges 222, the second small ridges 224, the bottomed part 150, and the recesses 240 of the side wall are drawn in cross section, and the second side wall 180 and the end part 250 The outline is drawn. As can be seen from FIG. 17, the first ridges 222 including the ridges 220 and the second ridges 224 of the second small ridges 224 can be seen from the opening side of the stopper portion 140. The recess 240 is formed so that the central portion of the second side wall 180 is convex toward the first side wall 160, that is, inside the stopper portion 140 (inner space side). Therefore, it can be manufactured as follows. FIG. 18 is an explanatory view schematically showing how the wheel stopper 10 of this embodiment is manufactured.

  As shown in the drawing, the manufacturing process of the wheel stopper 10 is roughly divided into two. First, the stopper portion 140 having a shape not having the recess 240 is raised from the base 120 and molded, and secondly, the recess 240 is molded on the second side wall 180 of the stopper portion 140. In each of these steps, it can be further subdivided for the convenience of the mold set. In the first molding, as shown in FIG. 18A, the lower mold of the concave mold and the upper mold of the convex mold are arranged to face each other, and the workpiece W is set therebetween. The workpiece W is a thin steel plate having a thickness of about 1 to 3 mm, for example, a stainless steel plate, and is subjected to mold molding using upper and lower molds to become an intermediate molded product of the wheel stopper 10. The lower mold has a shape in which the mold surface of the cavity K follows the outer shape of the base 120 and the stopper portion 140 of the wheel stopper 10, and the upper mold has the mold surface of the convex mold T as the base of the wheel stopper 10. 120 and the inner shape of the stopper part 140. In this case, the mold surface for molding the stopper portion 140 follows the second side wall 180 not having the recess 240. Since the rising height of the stopper portion 140, that is, the press cost of the workpiece W is several tens of times the plate thickness, the workpiece W is subjected to deep drawing. The plate thickness of the workpiece W described above is not limited to the above numerical range, and various thicknesses can be selected in consideration of the pressing ability for deep drawing and the weight of the wheel stopper 10. In the second molding following the molding of the intermediate molded product described above, as shown in FIG. 18B, the inner mold is inserted inside the intermediate molded product, and the outer mold is brought close to the inner mold, and thereafter molded. To form the recess 240 in the second side wall 180. In this case, the cavity K formed by the inner mold and the mold surface of the outer mold follow the shape of the recess 240 that is recessed toward the first side wall 160 in the center of the second side wall 180.

  In the wheel stopper 10 of the present embodiment described above, the stopper portion 140 is raised upward from the flat base 120 installed on the floor surface, and the first side wall 160 in the stopper portion 140 is connected to the bottomed portion 150. From the top to the base 120 as the top, a wheel interference portion that performs a stopper function is used. FIG. 19 is an explanatory diagram for explaining the function as a wheel stopper while showing the relationship between the wheel and the wheel stopper 10. As shown in the drawing, in the wheel stopper 10 of this embodiment, the stopper portion 140 is raised from the base 120 to a height of about 1/3 of the wheel WH, so that the wheel WH is placed on the first side wall 160 of the stopper portion 140. By interfering, it reliably functions as a stopper that prevents the wheel WH from rolling any further. In this case, the rising height of the stopper portion 140 can be set to about half the diameter of the wheel WH.

  On the other hand, the wheel stopper 10 of the present embodiment, the first side wall 160 and the second side wall 180 that are the interference part of the wheel face each other, hung on both side walls, the third side walls 200R, 200L are extended to face each other, The stopper portion 140 has a bottomed convex shape surrounding the opening with the side wall. For this reason, according to the wheel stopper 10 of the present embodiment, the strength of the stopper portion 140 rising from the base 120 is ensured. In addition, the wheel stopper 10 according to the present embodiment is configured so that the first side wall 160 has the ridges 220, the first small ridges 222, and the second small ridges 224 from the base thereof in the width direction of the first side wall 160 (wheels). It is assumed that the first side wall 160 itself is raised with these ridges arranged in parallel in the width direction. Therefore, according to the wheel stopper 10 of the present embodiment, the strength of the first side wall 160 serving as the interference portion of the wheel WH is increased by the ridge 220, the first small ridge 222, and the second small ridge provided on the first side wall. It can be increased by Article 224.

  In addition, in the wheel stopper 10 of this embodiment, the stopper portion 140 having an opening includes the first side wall 160, the third side wall 200R on both sides thereof, and the ends of the third side wall 200L, and the base 120 and its base edge portion. Surrounded by 120R and base edge 120L. For this reason, the stopper part 140 can be reinforced with the base 120 in the opening part. As a result, according to the wheel stopper 10 of the present embodiment, it is not necessary to use another member for reinforcing the stopper portion 140 having a bottomed convex shape, so that the weight can be reduced. In addition, according to the wheel stopper 10 of the present embodiment, the first side wall 160 of the stopper portion 140 itself is bulged by the protruding ridge 220, the first small ridge 222, the second small ridge 224, and the base 120 is reinforced. As a result, it is possible to ensure the strength to withstand practical use.

  The wheel stopper 10 of this embodiment described above has the bottomed stopper portion 140 raised from the flat base 120 and then the ridge 220, the first small ridge 222, and the second small ridge on the first side wall 160. Also for 224, the first side wall 160 itself was raised. Therefore, as described with reference to FIG. 18, a lower mold having a cavity K shaped according to the outer shape of the base 120 and the stopper portion 140, and a mold surface shaped like the inner shape of the base 120 and the stopper portion 140. The wheel stopper 10 of the present embodiment can be easily manufactured by the deep drawing of the workpiece W (thin steel plate) using the upper mold of the convex mold T having the above, and the cost can be reduced.

  Further, in the wheel stopper 10 of the present embodiment, the first side wall 160 of the stopper portion 140 is raised from the base 120, and the ridge 220 is provided at the base portion of the first side wall 160. Therefore, as shown in FIG. 19, when the wheel WH rolls on the first side wall 160 after riding on the base 120, the wheel WH does not interfere with the first side wall 160 of the stopper portion 140 before the ridge 220. Abut. For this reason, since the vehicle operator can immediately detect that the wheel WH interferes with the first side wall 160 due to the contact of the wheel WH with the ridge 220, the stop operation through the subsequent brake operation becomes simple. In this case, even if the wheel WH rolls over the ridge 220 and rolls, the wheel WH interferes with the first side wall 160 as described above and no further rolling occurs.

  In addition, the wheel stopper 10 of the present embodiment includes a recess 240 at substantially the center of the second side wall 180 facing the first side wall 160 that interferes with the wheel WH, and the recess 240 is formed on the first side wall 160 side. The recess is recessed so as to be convex, and is hung from the bottomed portion 150 to the end of the second side wall 180. Therefore, according to the wheel stopper 10 of the present embodiment, the second side wall 180 can be reinforced by the recess 240, so that the strength of the stopper portion 140 can be further increased. As a result, in the wheel stopper 10 of this embodiment, even if only a thin steel plate (stainless steel plate) having a thickness of 1 to 3 mm is used, the effectiveness of securing the strength to withstand practical use is enhanced.

  Next, a modified example that further increases the strength of the stopper portion 140 will be described. FIG. 20 is a schematic perspective view showing a modified reinforcing material 300.

  As shown in the figure, the reinforcing member 300 is a bent and formed material of a thin steel plate similar to the wheel stopper 10 described above, and includes a first wall member 310 inclined on the back side in the drawing, from both ends of the wall member. Second wall members 320R and 320L are provided to protrude. The first wall member 310 includes a concave groove 330 that is more inclined at the center thereof, and the left and right second wall members 320R and 320L have a bent portion 322 on the front side in the drawing. Since the lower ends of the first wall member 310, the second wall members 320R and 320L, and the bent portion 322 are so-called flush, the reinforcing member 300 is self-supporting as illustrated.

  The second wall member 320R has an upper end contour as an inclined receiving seat 324 that is curved and inclined from the bent portion 322 side, and the first receiving seat 326 and the second receiving seat 328 are provided on the receiving seat, and the second wall member 320R is inclined. The upper end of the receiving seat 324 is a ceiling receiving seat 340. The ceiling seat 340 has a shape that matches the shape of the inner diameter surface of the bottomed portion 150 of the stopper portion 140 of the wheel stopper 10 described above, and the inclined seat 324 is the shape of the inner wall surface of the first side wall 160 of the stopper portion 140. It is a shape that matches. The first receiving seat 326 and the second receiving seat 328 also have shapes that match the inner wall surface shapes of the first small protrusions 222 and the second small protrusions 224 of the first side wall 160, respectively. The same applies to the second wall member 320L. The rising heights of the first wall member 310 and the left and right second wall members 320R and 320L are the same as the height from the bottom surface of the base 120 of the wheel stopper 10 to the inner wall surface of the bottomed portion 150 of the stopper portion 140. Yes. In addition, the groove 330 has the same degree of inclination as the recess 240 in the second side wall 180 of the stopper 140, and cooperates with the left and right first wall members 310 to form the recess 240 from the inside of the stopper 140. It is formed so as to surround. That is, the first wall member 310 is formed so as to coincide with the inner wall surface of the second side wall 180, specifically, the inner side surface of the recess 240 in the range on both sides of the groove portion 330.

  The reinforcing material 300 is incorporated into the wheel stopper 10 as follows. FIG. 21 is an explanatory view showing how the reinforcing member 300 is assembled from the rear side of the wheel stopper 10, FIG. 22 is an explanatory view showing the assembled state of the reinforcing member 300 from the bottom side of the wheel stopper 10, and FIG. It is explanatory drawing which shows the wheel stopper 10 in cross-sectional view in the state in which the material 300 was incorporated.

  As indicated by the white arrow in FIG. 21, the reinforcing member 300 is incorporated into the stopper portion 140 from the opening on the bottom surface side. In the assembled state shown in FIG. 22, the reinforcing member 300 extends the first wall member 310 from the end portion of the second side wall 180 to the bottomed portion 150 and joins it to the inner wall surface of the second side wall 180. Moreover, about 2nd wall material 320R, 320L joined to the 1st wall material 310 on either side, these are extended from the 1st wall material 310 to the 1st side wall 160 side of the stopper part 140. As shown in FIG. Then, the reinforcing member 300 causes the inclined receiving seats 324 of the second wall members 320R and 320L to abut on the inner wall surface of the first side wall 160, and the ceiling receiving seat 340 is placed on the inner wall surface of the bottomed portion 150 with the first small convexity. The first receiving seat 326 and the second receiving seat 328 are brought into contact with the inner wall surfaces of the strip 222 and the second small convex strip 224, respectively. As described above, the recess 240 of the second side wall 180 is surrounded by the groove 330 and the first wall member 310. In this case, the reinforcing material 300 can be fixed by bonding with the adhesive on the inner wall surface of the second side wall 180 or the recess 240, or the reinforcing material 300 can be fixed by spot welding or the like at the bottom of the recess 240.

  According to the modified example described above, the stopper portion 140 can be reinforced from the inside by the reinforcing member 300 incorporated from the opening of the stopper portion 140, so that the strength of the stopper portion 140 can be further improved. And since the reinforcing material 300 is a bending molding material of a thin steel plate, the weight reduction of the wheel stopper 10 is not impaired. Further, the reinforcing member 300 surrounds the recess 240 of the second side wall 180 with the groove portion 330 and the first wall members 310 on the left and right sides thereof, and the second wall members 320R and 320L at both ends of the first wall member 310. The stopper part 140 is reinforced with Therefore, it is possible to reinforce the stopper portion 140 from the inside with high effectiveness, and to prevent the position of the reinforcing member 300 from being displaced.

  Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments, and can be implemented in various modes without departing from the scope of the present invention. For example, in the above-described embodiment, the wheel stopper 10 is manufactured by deep drawing of a thin steel plate. However, the mold described with reference to FIG. If the wheel stopper 10 is made of resin, it is possible to achieve both weight reduction and ensuring strength even if the thickness of each part is about 10 to 20 mm.

  In addition, the second side wall 180 of the stopper portion 140 can be a flat and inclined side wall without the recess 240, and the first side wall 160 side of the left and right third side walls 200 </ b> R and the second wall material 320 </ b> L. It can also be a curved and inclined side wall.

  In addition, the reinforcing material 300 can be modified as follows. FIG. 24 is a schematic perspective view showing a reinforcing member 300A of another modification. As shown in the figure, the reinforcing member 300A is different from the reinforcing member 300 described above, and does not include the groove portion 330 but includes the second wall member 320 joined between the first wall member 310 and the bent portion 322 facing each other. . The reinforcing member 300 is the same as the reinforcing member 300 in that it has an inclined receiving seat 324 and the like. The reinforcing member 300 </ b> A of this modified example is incorporated in the stopper portion 140 so that the first wall member 310 is joined to the inner wall surface of the second side wall 180 on both sides of the recess 240. 140 is reinforced from the inside.

  In the present embodiment, the ridge 220 has an upper surface parallel to the base 120. However, the wall surface of the first side wall 160 similar to the first small ridge 222 and the second small ridge 224 has an arc shape. It can also be a raised ridge. In addition, in this embodiment, the ridges including the ridges 220 are arranged in parallel to the width direction of the first side wall 160. However, like the first small ridges 222, A plurality of ridges whose wall surfaces are raised in an arc shape are extended from the bottomed portion 150 of the first side wall 160 to the base 120 side, or a plurality of ridges are received obliquely from the bottomed portion 150 toward the base 120 side. It can also be done. Even in this case, the strength of the stopper portion 140 can be secured.
