- the protrusion 84 is positioned midway on the lower surface of the elastic piece 50 and protrudes downward, and abuts on or approaches the bracket 26 as shown in FIG. By providing the projection 84, stress concentration generated around the slit end 86 when the elastic piece 50 is bent is reduced.
- the bottom 30 of the case 120 has a seating surface 88, a circumferential wall 90, an extension 91, and an overhanging wall 92.
- a bolt hole 94 for inserting a bolt is formed at the center of the seat surface 88.
- the seat surface 88 is tightened by the bolt 12 to the vehicle body side via the bracket 26. Thereby, the hook device 100 is fixed to the vehicle body side.
- the circumferential wall 90 is erected around the seating surface 88 and is formed in a cylindrical shape.
- the circumferential wall 90 allows the seating surface 88 to be recessed to accommodate the screw head of the bolt 12 as shown in FIG.
- the extension portion 91 extends from the upper end of the circumferential wall portion 90 and is formed in a flat plate shape.
- the elastic piece 50 extends in the axial direction of the shaft 24 from the extension portion 91 and is formed flat in the same plane as the extension portion 91.
- the extension portion 91 functions as a support portion for supporting the elastic piece 50. As shown in FIG. 9, the elastic piece 50 extends parallel to the shaft 24 from the extension portion 91, and is formed so as to bend and rise on the tip end side of the protrusion 84.
- the overhanging wall 92 projects downward from the extension 91 and projects laterally from the circumferential wall 90.
- the overhanging wall portion 92 abuts the bracket 26 at a position where the elastic piece 50 and the shaft 24 overlap in the axial direction, and suppresses the deformation of the extending portion 91. Further, since the overhanging wall portion 92 abuts the bracket 26 by the bolt 12 together with the seat surface 88, the overhanging wall portion 92 stably supports the elastic piece 50 via the extending portion 91.
- the protrusion 84 is located on the distal end side of the proximal end 50 a of the elastic piece 50 and is located on the distal end side of the elastic piece 50 than the slit ends 86 on both sides of the elastic piece 50.
- the projection 84 protrudes downward and abuts on or approaches the lower bracket 26. When the elastic piece 50 bends downward, the projection 84 abuts on the bracket 26.
- the elastic piece 50 extends from the extension portion 91 in the axial direction of the shaft 24, and a load is applied to the extension portion 91 from the base end 50 a of the elastic piece 50 when it is bent by the rotation of the hook 22. . If the protrusion 84 is not provided, stress may concentrate around the slit end 86. Therefore, in order to disperse stress around the proximal end 50 a of the elastic piece 50, particularly around the slit end 86, the elastic piece 50 is provided with a protrusion 84.
- FIG. 11 is a diagram for explaining the action of the protrusion 84.
- FIG. FIG. 11 shows a cross section of the case 120 and the bracket 26.
- the radial contact portion 51 of the elastic piece 50 is pushed downward by the rotation of the hook 22 and the elastic piece 50 is bent.
- the protrusion 84 at the middle of the elastic piece 50 abuts on the bracket 26, the load on the radial contact portion 51 will be received by the protrusion 84, and the load on the proximal end 50a side is reduced. The stress generated around the end 50a can be reduced.
- the overhanging wall portion 92 is fixed to the bracket 26 by the bolt 12 together with the seat surface 88, it is possible to suppress the deformation of the extending portion 91 even when receiving an upper load with the projection 84 as a fulcrum. it can.
- the stress concentration on the base end 50a side of the elastic piece 50 is dispersed when the elastic piece 50 is bent, the reduction in durability can be suppressed even if the elastic piece 50 is formed integrally with the case 120. Further, since the elastic piece 50 bends with the protrusion 84 as a fulcrum, the biasing force to the hook 22 can be increased.
- the protrusion 84 opposes the overhanging wall 92 across the proximal end 50 a of the elastic piece 50.
- the overhanging wall portion 92 abuts the bracket 26 by tightening the bolt 12 together with the seat surface 88. Thereby, the stress concentration can be suppressed by supporting the proximal end 50 a of the elastic piece 50 where stress is likely to be concentrated by the overhanging wall portions 92 and the protrusions 84 located on both sides.
- the protrusion 84 is located on the distal end side of the proximal end 50 a and is located on the proximal end 50 a side of the center of the elastic piece 50. As a result, it is possible to disperse the stress on the proximal end 50 a side while securing the ease of bending of the elastic piece 50 and appropriately setting the operation feeling of the hook 22.
- first restriction portion 56 is formed on the cover portion 38 and the second restriction portion 54 is formed on the bottom portion 30 is shown, however, the present invention is not limited to this aspect.
- a portion may be formed in the cover portion 38 to receive the load from the hook 22.
- the embodiment shows the aspect in which the elastic piece 50 extends from the bottom 30, it is not limited to this aspect.
- the elastic piece may extend from the side wall 34 of the case 20 along the axial direction of the shaft 24.
- the present invention relates to a hook device for a vehicle.
