  In the in-vehicle camera described in Patent Document 1, the in-vehicle camera body (in-vehicle component) is held by the bracket by the biasing force of the plate spring. Therefore, in order to hold the in-vehicle component firmly, it is necessary to There is. However, in the structure of Patent Document 1, when attaching an on-vehicle component to the bracket, the plate spring must be pressed and elastically deformed from the direction that opposes the biasing force of the plate spring. When elastically deforming the leaf spring, a strong force is required, which may lead to complication of the engagement operation. For this reason, it is difficult to simultaneously achieve the enhancement of the holding power of the in-vehicle component and the improvement of the mounting workability.

  Then, this invention aims at provision of the mounting structure of the vehicle-mounted components which can make reinforcement of the retention strength of vehicle-mounted components, and the improvement of attachment workability compatible.

  In order to achieve the above object, a first aspect of the present invention comprises a bracket and an on-vehicle component. The bracket has a pair of support surfaces and a rotation restricting engagement portion, and is fixed to the vehicle body side. The pair of support surfaces are spaced apart from one another in a first direction and extend along a second direction intersecting the first direction. The rotation restricting engagement portion is disposed apart from the pair of support surfaces between the pair of support surfaces when viewed from the second direction. The on-vehicle component has a pair of shaft-like protrusions and a rotation restricting locking portion and is held by the bracket. The pair of axial protrusions project on both sides in the first direction corresponding to the pair of support surfaces. The rotation restricting locking portion is engageable with the rotation restricting engagement portion.

  The pair of support surfaces is provided with a pair of recesses that hold the pair of protrusions. A pair of leaf spring members opposite to each of the pair of recesses are fixed to the bracket. The leaf spring member is elastically deformed in a third direction crossing the first and second directions by the protrusion moving on the support surface from one side to the other side in the second direction, and a protrusion to the recess is formed. And allows the projection accommodated in the recess to be resiliently urged from the third direction to the recess. By inclining the on-vehicle component about the pair of protrusions which enter between the support surface and the plate spring member, the rotation restricting locking portion can be engaged with the rotation restricting engaging portion. The engagement between the rotation restricting locking portion and the rotation restricting engaging portion restricts tilting of the in-vehicle component centering on the pair of projecting portions. The on-vehicle component is held on the bracket by the leaf spring member elastically holding the projection between the recess and the rotation restricting engagement portion engaging with the rotation restricting engagement portion.

  In the above configuration, the leaf spring member elastically holds the protrusion between the recess and the recess by urging the protrusion accommodated in the recess from the third direction to the recess from the third direction, and the rotation restriction locking portion The engagement of the rotation restricting engagement portion with the rotation restricting engagement portion restricts the tilt of the in-vehicle component centering on the pair of protrusions. For this reason, the change of the attachment angle of the vehicle-mounted components with respect to a bracket is prevented reliably, and vehicle-mounted components can be reliably hold | maintained with respect to a bracket.

  Further, when mounting the in-vehicle component to the bracket, the pair of projecting portions of the in-vehicle component elastically deforms the plate spring member in the third direction, and the supporting surface is moved from one side to the other side in the second direction. Move to That is, the pair of protrusions of the in-vehicle component moves in a second direction intersecting with the third direction in which the biasing force of the plate spring member is applied, and in order to securely hold the in-vehicle component Even when the biasing force is increased, the increase in the resistance that the protrusion receives from the plate spring member when moving the protrusion is smaller than the increase in the biasing force of the plate spring member. Therefore, it is possible to simultaneously achieve the enhancement of the holding power of the in-vehicle component and the improvement of the mounting workability.

  A second aspect of the present invention is the first aspect, wherein the support surface and the leaf spring member allow movement of the protrusion on the support surface to the other side in the second direction than the recess. The protrusion is accommodated in the recess by moving the in-vehicle component tilted about the pair of protrusions entering the other side of the second direction from the recess to one side in the second direction, and the elastic retention is achieved At the same time, the rotation restricting engagement portion engages with the rotation restricting engagement portion.

  In the above configuration, when the rotation restricting locking portion is engaged with the rotation restricting engaging portion, the in-vehicle component tilted about the pair of protruding portions entering the other side in the second direction than the recessed portion is Move to one side in the 2 direction. As a result, the protrusion is accommodated in the recess and elastically held, and the rotation restricting engagement portion engages with the rotation restricting engagement portion. Therefore, since a strong force is not required when the rotation restricting locking portion is engaged with the rotation restricting engaging portion, the in-vehicle component can be easily attached to the bracket.

  A third aspect of the present invention is the first aspect, wherein the rotation restricting locking portion restricts the rotation by tilting the in-vehicle component centering on the pair of projecting portions accommodated and elastically held in the recess. Engage in the engaging part.

  In the above-described structure, when the rotation restricting locking portion is engaged with the rotation restricting engaging portion, the in-vehicle component is tilted about the pair of projecting portions housed and elastically held in the recess, and the rotation restricting lock is engaged. It is only necessary to engage the part in the rotation restricting engagement part. Therefore, the on-vehicle component can be easily attached to the bracket.

Do. That is, the pair of projecting portions 40 of the in-vehicle camera 6 moves in the back and forth direction that intersects the vertical direction to which the biasing force of the plate spring 5 is applied, so that the in-vehicle camera 6 can be reliably held. Even when the biasing force is increased, the amount of increase in resistance that the protrusion 40 receives from the plate spring 5 when moving the protrusion 40 is smaller than the amount of increase in the biasing force of the plate spring 5. Therefore, it is possible to achieve both the enhancement of the holding power of the on-vehicle camera 6 and the improvement of the mounting workability.

  In the above-described configuration, when the engagement protrusion 41 is engaged with the engagement hole 19 of the engagement portion 18, the on-vehicle camera 6 is tilted about the pair of protrusions 40 that enter the rear of the recess 24. Move forward. As a result, the projection 40 is accommodated in the recess 24 and elastically held, and the engagement projection 41 engages with the engagement hole 19 of the engagement portion 18. Therefore, since a strong force is not necessary when the engagement protrusion 41 is engaged with the engagement hole 19, the on-vehicle camera 6 can be easily attached to the camera bracket 4.
