  As described above, when the mounting device is disposed between the upper portion of the heat exchanger and the upper portion of the shroud and between the lower portion of the heat exchanger and the lower portion of the shroud, the lower mounting device and Since the weight of the heat exchanger is added to the lower part of the shroud, the strength of the lower part of the shroud for supporting the lower mounting device becomes a problem, and it is difficult to obtain stable dynamic damper characteristics. Further, if the strength of the lower portion of the shroud is increased, the thickness of the lower portion increases, and the weight of the shroud increases.

  Therefore, as in the above-mentioned Patent Document 1 or 2, mounting devices are respectively provided on the upper portions of the side portions on both sides in the vehicle width direction of the heat exchanger, and the heat exchanger is used with these mounting devices (so-called suspension type mounting devices). It is conceivable to support the weight.

  However, when the suspension type mounting device is adopted, it is necessary to support the weight of the heat exchanger through the mounting device at the place where the mounting device is supported in the shroud. There is a problem in securing the strength for supporting the device. Further, as in Patent Document 2, when the mounting bracket provided on the mounting device is clipped to the carrier (shroud), the heat exchanger is replaced when replacing the heat exchanger with a new one. There is a high possibility that the operation of detaching from the shroud fixed to the vehicle body member becomes difficult, and in particular, the operation of removing the clip of the mounting bracket becomes difficult.

  The present invention has been made in view of such points, and an object of the present invention is to ensure sufficient strength of the shroud to support the mounting device and to install a new vehicle heat exchanger. It is an object of the present invention to provide a mounting structure for a vehicle heat exchanger that can facilitate the work of attaching / detaching the vehicle heat exchanger to / from the shroud.

In order to achieve the above object, according to one aspect of the present invention , there is provided a shroud that supports a vehicle heat exchanger mounted on a vehicle so that the vehicle heat exchanger can be vibrated up and down. A shroud provided with a vehicle body fixing portion to be fixed to a vehicle body member of the vehicle on both sides of the shroud in the vehicle width direction, and provided on both sides of the vehicle heat exchanger in the vehicle width direction. And a mounting device that supports the supported portions so as to be able to vibrate up and down with respect to the side portions of the shroud in the vehicle width direction, each mounting device holding an elastic member and via the elastic member A mount main body for supporting each supported portion with respect to each side portion of the shroud, and the mount of each mount device is positioned above the vehicle body fixing portion on each side portion of the shroud. Each mounting device has a receiving portion for supporting the lower surface of the mounting body, and each mounting device has a receiving portion for supporting the lower surface of the mounting body. the vehicles rear mounting body of the device, the mount main body fixing bracket for fixing to the respective side of the shroud is provided a said respective installation part after the vehicle of each side of the shroud Each of the mounting devices is provided with a receiving recess that is open on the rear side of the vehicle, and the receiving portion of each installation portion is provided below the receiving recess. The fixing bracket is provided on the vehicle rear side of each of the housing recesses, each of which is configured by an upper surface of a side wall portion and in which the mount main body of each of the mounting devices is housed. The upper surface of the lower side wall portion of the housing recess is formed by the mounting device attached to the supported portions on the side portions on both sides in the vehicle width direction of the vehicle heat exchanger mounted on the lower portion of the shroud. When the mount body is inserted into the receiving recesses on the sides on both sides in the vehicle width direction of the shroud from the open side to the back side, the insertion causes the vehicle heat exchanger to float from the lower part of the shroud. And it was set as the structure made into the inclined surface which becomes so high that the back | inner side of the said accommodation recessed part .

  With the above configuration, the side walls on both sides in the vehicle width direction of the shroud have wall portions extending in the vertical direction, and the wall portions extending in the vertical direction are higher than the wall portions extending in the horizontal direction at the upper and lower portions of the shroud. Since it has high strength against the load in the vertical direction, it is possible to sufficiently secure the strength of the shroud for supporting the mounting device (and hence the radiator). In addition, since the vehicle body fixing portions are respectively provided on the sides of the shroud in the vehicle width direction, the entire shroud including the vehicle heat exchanger can be supported with sufficient strength against the vehicle body member. Furthermore, since the mounting bracket is provided on the vehicle front side or rear side of the mount body, by fastening or unfastening bolts from the vehicle front side or rear side of the mount body (that is, the vehicle front side or rear side of the shroud), etc. The fixing bracket can be attached to or detached from the shroud. As a result, the heat exchanger can be easily attached to and detached from the shroud when the heat exchanger is replaced with a new one.

In addition, the vehicle heat exchanger can be easily supported in the housing recess, and the strength of the shroud for supporting the mounting device can be further increased. Further, the mounting device (mount main body) can be prevented from coming off from the housing recess by the fixing bracket.

Furthermore, with the vehicle heat exchanger mounted on the lower part of the shroud , the vehicle heat exchanger is removed from the lower part of the shroud by inserting the mount body attached to the supported part of the vehicle heat exchanger into the receiving recess. It can be raised. As a result, the vehicle heat exchanger can be easily and properly assembled to the shroud together with the mount device, and therefore, the assembly of the vehicle heat exchanger and the mount device to the shroud can be improved. .

Is easy to insert. In addition, the inclined surface portion slides with respect to the inclined surface of the receiving portion in the middle of insertion into the receiving recess of the mount body, but the curved surface portion is raised from the inclined surface of the receiving portion. The sliding resistance of the inclined surface portion with respect to the inclined surface of the receiving portion can be reduced as compared with the case where substantially the entire lower surface of the mount body in the vehicle front-rear direction is the inclined surface portion.

  When the lower surface of the mount body is composed of the inclined surface portion and the curved surface portion, the lower surface of the mount body is formed such that an intermediate portion in the vehicle width direction on the lower surface protrudes downward and extends in the vehicle front-rear direction. And a lower surface of the protruding portion is configured by the inclined surface portion and the curved surface portion, and an upper surface of a lower side wall portion of the housing recess is fitted in the protruding portion and extends in the vehicle front-rear direction. It is preferable to have a fitting recess that is recessed to extend, and that the inclined surface of the receiving portion is formed on the bottom surface of the fitting recess.

  Thus, the protrusions are fitted in the fitting recesses, whereby the vehicle heat exchanger can be positioned in the vehicle width direction with respect to the shroud. Therefore, the vertical vibration characteristic with respect to the shroud of the heat exchanger for vehicles by the mounting devices on both sides in the vehicle width direction can be stabilized.

Since the hole 43a of the elastic member 43 of each mount main body 41 and the protrusion 11 fitted in the hole 43a have a quadrangular cross section as described above, the elastic member 43 (mount main body 41) is the protrusion 11. It is formed in the shape which does not rotate around. The cross-sectional shapes of the hole 43a and the protrusion 11 may be any shape as long as the elastic member 43 does not rotate around the protrusion 11.

  As shown in FIG. 7, each mount device 40 is disposed at a position above the vehicle body fixing portion 28 on the rear surface of each side wall portion 24 of the shroud 21 (upper end portion on the rear surface of each side wall portion 24). An installation portion 50 (in this embodiment, an accommodation recess 51 described later) in which the mount body 41 is installed is provided. Each installation portion 50 includes a receiving portion 57 that supports the lower surface of the mount body 41 (that is, the lower surface of the holding member 44). The receiving parts 57 and 57 of the two left and right installation parts 50 and 50 receive the total weight of the radiator 1. In the present embodiment, the receiving portion 57 is located in the vicinity of the upper side of the vehicle body fixing portion 28 in each side wall portion 24.

  Each installation part 50 is comprised by the accommodation recessed part 51 dented in the front side and open | released the back side where the mount main body 41 of each mount apparatus 40 is each installed and accommodated. Each housing recess 51 includes an upper wall portion 52 that is an upper wall portion of the housing recess 51, a lower wall portion 53 that is a lower wall portion, and a front wall portion 54 that is a front wall portion (that is, the side wall portion 24). , And a vehicle width direction outer side wall portion 55 (that is, a rear extension portion 24a of the side wall portion 24) which is a wall portion on the outer side in the vehicle width direction. The mount main body 41 (holding member 44) of each mount device 40 is fixed to the side wall portion 24 of the shroud 21 by a fixing bracket 45 in a state where the mount main body 41 (holding member 44) is fitted in the housing recess 51. Here, in the present embodiment, each storage recess 51 is also open on the inner side in the vehicle width direction. In the following description, the open side of the storage recess 51 is the rear side of the storage recess 51. The back side of the housing recess 51 is the side opposite to the open side, that is, the front side of the housing recess 51. In addition, you may make it form the vehicle width direction inner side wall part which is a wall part inside the vehicle width direction of each accommodating recessed part 51. As shown in FIG. In this case, a cutout portion that is cut out from the rear end face of the vehicle width direction inner wall portion toward the front side and through which the protruding portion 11 can pass is formed in the vehicle width direction inner wall portion.

  The receiving portion 57 of each installation portion 50 is configured by the upper surface of the lower side wall portion 53 of the housing recess 51. The fixing bracket 45 is provided on the rear side of the housing recess 51 so as to cover the open portion on the rear side of the housing recess 51. Since the fixing bracket 45 and the bolts 46, 46 do not bear the weight of the radiator 1, the mount main body 41 is fixed by the fixing bracket 45 so that the mount main body 41 (mount device 40) does not come off from the housing recess 51. It is sufficient if it is fixed to the extent that it does.

  The lower side wall 53 of each housing recess 51 includes a plurality of (two in the present embodiment) ribs 53a and 53a extending in the front-rear direction and the vertical direction with a space in the vehicle width direction. The receiving portion 57 of each installation portion 50 is configured by the upper surfaces of the ribs 53 a and 53 a in the lower side wall portion 53. This makes it possible to improve the strength of the lower side wall 53 while reducing the thickness of the lower side wall 53 of the housing recess 51 by the ribs 53a and 53a. Note that the ribs 53a and 53a of the lower side wall portion 53 may be eliminated, and the entire upper surface of the lower side wall portion 53 may be used as the receiving portion 57.

  Similarly to the lower side wall portion 53, the upper side wall portion 52 of each housing recess 51 also has a plurality of (two in this embodiment) ribs 52a and 52a extending in the front-rear direction and the vertical direction. The upper surface of the mount main body 41 (the upper surface of the holding member 44) abuts on the lower surfaces of the ribs 52a and 52a (strictly, there is a slight gap when the mount main body 41 is accommodated in the accommodating recess 51). . The front side wall portion 54 also has a plurality of ribs 54a, 54a,.

  The receiving portion 57 (the upper surface of the ribs 53 a and 53 a in the lower wall portion 53) of each installation portion 50 is an inclined surface that becomes higher toward the back side of the housing recess 51. Corresponding to the inclined surface of the receiving portion 57, the lower surface of the holding member 44 (the lower surface of the mount body 41) is configured with an inclined surface portion 44 a that is inclined so as to be higher toward the back side of the housing recess 51. This is for facilitating the work of assembling the radiator 1 and the mounting devices 40, 40 to the shroud 21, as will be described later. Further, the lower surface of the upper side wall portion 52 is an inclined surface that becomes lower toward the back side of the housing recess 51. Corresponding to this inclined surface, the upper surface of the holding member 44 (the upper surface of the mount main body 41) is configured by an inclined surface portion 44b that is inclined so as to become lower toward the back side of the housing recess 51.

  In the present embodiment, as shown in FIG. 8, a pin portion protruding downward and covered with an elastic body 14 on the lower surface of the radiator 1 (in this embodiment, the lower surfaces of the left and right tank portions 2, 2). 13 is provided. The elastic body 14 around each pin portion 13 is made of a rubber member and is fixed to the lower surface of the tank portion 2. The elastic body 14 has a large diameter portion 14a on the tank portion 2 side and a small diameter portion 14b on the anti-tank portion 2 side. In addition, the pin part 13 provided in the lower surface of the radiator 1 may be one, or may be three or more.

  On the other hand, insertion holes 23b and 23b are respectively formed at the end portions on the both sides in the vehicle width direction of the rear extending portion 23a of the lower wall portion 23 of the shroud 21 (portions directly below the left and right tank portions 2 and 2). Yes. The left pin portion 13 and the small diameter portion 14b of the elastic body 14 are inserted into the left insertion hole 23b, and the right pin portion 13 and the small diameter portion 14b of the elastic body 14 are inserted into the right insertion hole 23b. . A predetermined amount of gap is formed between the outer peripheral surface of the small diameter portion 14b of each elastic body 14 and the inner peripheral surface of each insertion hole 23b. That is, even if the radiator 1 attempts to vibrate in a direction perpendicular to the vertical direction with respect to the shroud 21 (horizontal direction such as the vehicle longitudinal direction or the vehicle width direction) more than the predetermined amount, at least one of the elastic bodies 14 The outer surface of the small diameter portion 14b abuts against the inner surface of the insertion hole 23b, thereby suppressing such a large horizontal vibration. In addition, between the lower surface of the large diameter portion 14a of each elastic body 14 and the upper surface of the rear extension portion 23a of the lower wall portion 23, and the portion other than the tank portions 2 and 2 on the lower surface of the radiator 1 and the rear side extension. A gap is also formed between the upper surface of the installation portion 23a, and even if the radiator 1 vibrates in the vertical direction with respect to the shroud 21, basically the lower surface of the large-diameter portion 14a of each elastic body 14 and The lower surface of the radiator 1 (portions other than the tank portions 2 and 2) does not come into contact with the upper surface of the rear extending portion 23 a of the lower wall portion 23.

  Next, a method of assembling the radiator 1 and the two mounting devices 40 and 40 to the shroud 21 will be described.

  First, the operator inserts and fits the left and right protrusions 11 and 11 of the radiator 1 into the holes 43a and 43a of the elastic members 43 and 43 in the mount bodies 41 and 41 of the mount devices 40 and 40, respectively. The mounting devices 40 and 40 are respectively attached to the protruding portions 11 and 11 (the protruding portions 11 and 11 and the mounting devices 40 and 40 are respectively engaged). Since the cross-sectional shape of the hole 43a of each elastic member 43 and each protrusion 11 fitted to each hole is a quadrangle, the mount body 41 (the elastic member 43 and the holding member 44) attached to each protrusion 11 is There is no rotation around the protrusion 11.

  Subsequently, the operator places the radiator 1 having the mounting devices 40 and 40 attached to the left and right projecting portions 11 and 11 on the upper surface of the rear extending portion 23a of the lower wall portion 23 of the shroud 21, respectively. At this time, it is necessary to insert the pin portions 13 and 13 and the small diameter portions 14b and 14b of the elastic bodies 14 and 14 into the insertion holes 23b and 23b formed in the rear extending portion 23a of the lower wall portion 23. However, since the mounting devices 40 and 40 attached to the left and right projecting portions 11 and 11 are not yet accommodated in the accommodating recesses 51 and 51, they are placed on the upper surface of the rear extending portion 23a of the lower wall portion 23. The radiator 1 is inclined obliquely so that the upper side is located on the rear side. Thus, even if the radiator 1 is inclined obliquely, the predetermined amount of gap is formed between the outer peripheral surface of the small diameter portion 14b of each elastic body 14 and the inner peripheral surface of each insertion hole 23b. The pin portions 13, 13 and the small diameter portions 14b, 14b of the elastic bodies 14, 14 can be inserted into the insertion holes 23b, 23b. In consideration of this, the predetermined amount is determined.

  Then, the operator moves the radiator 1 placed on the upper surface of the rear extending portion 23a of the lower wall portion 23 to be inclined, and the upper portion of the radiator 1 is moved forward with the lower surface of the radiator 1 as a base point. The mount main bodies 41 and 41 of the mount devices 40 and 40 attached to the left and right projecting portions 11 and 11 are rotated to the receiving recesses 51 and 51 of the shroud 21 from the open side (rear side) to the back. Insert each side (front side).

  Here, the receiving portion 57 (the upper surface of the ribs 53a and 53a in the lower side wall portion 53) of each installation portion 50 is an inclined surface that becomes higher toward the back side of the housing recess 51 as described above, and the holding member 44. Since the lower surface of the upper surface of the housing is formed with an inclined surface portion 44a that is inclined so as to become higher toward the back side of the housing recess 51, the mount body 41, 41 can be easily moved into the housing recess 51, 51 by the above-described rotation of the radiator 1. They can be inserted almost simultaneously.

  In the present embodiment, when the mount main bodies 41 and 41 are inserted into the receiving recesses 51 and 51 substantially simultaneously by the rotation of the radiator 1, the lower surface (inclined surface portion 44 a) of the holding member 44 of each mount main body 41 is the receiving portion. 57 is placed on the inclined surface and slides on the inclined surface as the insertion proceeds. By this sliding, each mount body 41 is gradually pushed up as the insertion proceeds. Since the protrusions 11 and 11 are also pushed up by this push-up, the radiator 1 is lifted from the upper surface of the rear extension 23 a of the lower wall portion 23 of the shroud 21. In this way, when the insertion is completed, between the lower surface of the large-diameter portion 14a of each elastic body 14 and the upper surface of the rear side extending portion 23a of the lower wall portion 23 and other than the tank portions 2 and 2 on the lower surface of the radiator 1 A gap is formed between the portion and the upper surface of the rear extension 23a.

  After the insertion is completed, each mounting bracket 41 (each mounting device 40) is accommodated and installed in each accommodation recess 51 by fixing each fixing bracket 45 to each side wall 24 of the shroud 21 with bolts 46, 46. In the state, it will not come off from each accommodation recess 51.

  As described above, the receiving portions 57 of the housing recesses 51 are respectively attached to the left and right projecting portions 11 of the radiator 1 placed on the lower portion of the shroud 21 (the upper surface of the rear extending portion 23a of the lower wall portion 23). When the mount bodies 41, 41 of the mounted devices 40, 40 are inserted into the housing recesses 51, 51 in the side wall portions 24, 24 on both sides in the vehicle width direction of the shroud 21 from the open side to the back side, respectively, The radiator 1 has an inclined surface that becomes higher toward the back side of the housing recess 51 so that the radiator 1 is lifted from the lower portion of the shroud 21 (the upper surface of the rear extending portion 23a of the lower wall portion 23).

  When replacing the radiator 1 with a new one at a service factory or the like, the operator removes the radiator 1 from the shroud 21 while the shroud 21 is fixed to the bumper beam 61 and the apron rain members 68 and 68, and thereafter A new radiator 1 is assembled to the shroud 21.

To remove the radiator 1 from the shroud 21, the operator, after unfastening the bolt 4 6, 4 6 from the rear side of the mount main body 41 (i.e. the rear side of the shroud 21), after the upper portion of the radiator 1 The mount main bodies 41, 41 of the mount devices 40, 40 are removed from the housing recesses 51, 51 of the shroud 21 while being tilted to the side. In the middle of this, the radiator 1 contacts the upper surface of the rear extension 23 a of the lower wall portion 23 of the shroud 21, and the radiator 1 does not fall from the shroud 21.

  When the mount main bodies 41, 41 of the mount devices 40, 40 are completely removed from the housing recesses 51, 51, the radiator 1 is the same as before the insertion of the mount main bodies 41, 41 into the housing recesses 51, 51 at the time of assembly. It will be in an inclined state. Mount devices 40 and 40 are attached to the protrusions 11 and 11 of the radiator 1, respectively. When the operator pulls up the radiator 1 to the upper side, the operation of removing the radiator 1 from the shroud 21 is completed.

  If there is no problem with the mounting devices 40, 40, the operator removes the mounting devices 40, 40 from the projections 11, 11 of the radiator 1 removed from the shroud 21, and these are removed from the projections 11, 11 of the new radiator 1. Attach to. Then, the operator assembles the radiator 1 and the mounting devices 40 and 40 to the shroud 21 in the same manner as the above-described assembling method.

  Therefore, in the present embodiment, the accommodation recess 51 (installation portion) in which the mount main body 41 of each mount device 40 is accommodated and installed at a position above the vehicle body fixing portion 28 in each side wall portion 24 extending in the vertical direction of the shroud 21. 50), and each receiving recess 51 has a receiving portion 57 that supports the lower surface of the mount body 41. Therefore, the strength of the shroud 21 for supporting the mounting devices 40 and 40 (and hence the radiator 1) is increased. It will be possible to secure enough. That is, the side wall portions 24, 24 extending in the vertical direction have higher strength against the load in the vertical direction than the upper wall portion 22 and the lower wall portion 23 extending in the horizontal direction. Can sufficiently secure the strength for supporting the radiator 1). Further, since the vehicle body fixing portions 28 and 28 are respectively provided on the side wall portions 24 and 24 on both sides in the vehicle width direction of the shroud 21, the entire shroud 21 including the radiator 1 is sufficiently strong against the bumper beam 61. It can be supported. In addition, normally, the vehicle body fixing portion 28 in each side wall portion 24 is reinforced (in this embodiment, reinforced by the reinforcing ribs 24b, 24b,...). The strength of the shroud 21 for supporting the mounting devices 40 and 40 can be further increased by providing the receiving portion 57 of the accommodating recess 51 in the vicinity of 28.

Furthermore, since a mounting bracket 45 for fixing the mount body 41 to each side wall 24 of the shroud 21 is provided on the rear side of the mount body 41 of each mount device 40, the rear side of each mount body 41 is provided. by bolts 4 6, 4 6 fastening or unfastening of from (the rear side of the shroud 21), the fixing bracket 45 can be adding or removing the shroud 21, exchange result, the radiator 1 with a new In doing so, the attaching / detaching operation of the radiator 1 to the shroud 21 is facilitated.

(Embodiment 2)
9 to 13 show a second embodiment of the present invention, in which the configuration of the mount body 41 of each mount device 40 and the configuration of the installation unit 50 related to the configuration are different from those of the first embodiment. It is a thing. 9 to 13, the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  That is, in the present embodiment, the lower surface of the mount main body 41 (the lower surface of the holding member 44) of each mount device 40 has a projecting portion extending in the front-rear direction, with the middle portion of the lower surface protruding in the vehicle width direction. 44c. The portions other than the protruding portions 44c on the lower surface of the holding member 44 (portions on both sides of the protruding portions 44c) are inclined surface portions 44a having the same shape as the inclined surface portions 44a in the first embodiment. The lower surface of the projecting portion 44c (which is also the lower surface of the mount body 41) is continuously provided on the front side of the vehicle with respect to the inclined surface portion 44d and the inclined surface portion 44d, and the height position of the lower surface of the mount body 41 is closer to the front side. It is comprised with the curved surface part 44e curved so that it might become high (refer FIG.11 and FIG.12).

  On the other hand, the upper surface of the lower side wall portion 53 of each housing recess 51 that constitutes each installation portion 50 has a fitting recess 53b that is recessed so that the protruding portion 44c is fitted and extends in the front-rear direction. A plurality of (two in the present embodiment) ribs 53c and 53c are formed on the bottom surface of the fitting recess 53b so as to extend in the front-rear direction and the up-down direction with a space in the vehicle width direction.

  Also in this embodiment, each installation part 50 has the receiving part 57 which supports the lower surface (namely, lower surface of the holding member 44) of the mount main body 41 similarly to the said Embodiment 1. FIG. The receiving part 57 of each installation part 50 is comprised by the upper surface (especially bottom face of the fitting recessed part 53b) of the lower side wall part 53 of the accommodation recessed part 51. FIG. In the present embodiment, as described above, the ribs 53c and 53c are formed on the bottom surface of the fitting recess 53b, and the upper surfaces of these ribs 53c and 53c constitute the receiving portion 57 of the installation portion 50. The upper surfaces of the ribs 53c and 53c are inclined surfaces similar to the upper surfaces of the ribs 53a and 53a described in the first embodiment (the left and right protrusions 11 and 11 of the radiator 1 mounted on the upper surface of the rear extension 23a). When the mount main bodies 41 and 41 of the mounted mounting devices 40 and 40 are respectively inserted into the housing concave portions 51 and 51 in the side wall portions 24 and 24 on both sides in the vehicle width direction of the shroud 21 from the open side to the back side, respectively. It is set as the inclined surface which becomes so high as the back | inner side of the accommodation recessed part 51 so that the radiator 1 may float from the upper surface of the rear side extension part 23a by this insertion. The ribs 53c and 53c may be eliminated, and the entire bottom surface of the fitting recess 53 may be used as the receiving portion 57 of the installation portion 50.

  The inclined surface portion 44d of the protruding portion 44c of each mount body 41 abuts on the upper surfaces of the ribs 53c and 53c. The inclined surface portion 44d of each mount body 41 corresponds to the inclined surface of the receiving portion 57, is inclined so as to be higher toward the front side, and is connected to the curved surface portion 44e.

  As shown in FIG. 12, the protrusion 44c of each mount body 41 has a tapered shape such that the width in the vehicle width direction of the protrusion 44c becomes smaller toward the front side of the protrusion 44c (tapered shape). To be formed. That is, the side surfaces of the projecting portion 44c on both sides in the vehicle width direction are formed so as to approach each other toward the front side in the front portion of the projecting portion 44c.

  In the same manner as in the first embodiment, when the radiator 1 and the two mounting devices 40 and 40 are assembled to the shroud 21, the operator is placed on the upper surface of the rear side extending portion 23 a of the lower wall portion 23 and is inclined. Of the mounting devices 40 and 40 attached to the left and right projecting portions 11 and 11, respectively, while rotating the radiator 1 so that the upper portion of the radiator 1 moves forward from the lower surface of the radiator 1 as a base point. The mount main bodies 41 and 41 are inserted into the housing recesses 51 and 51 of the shroud 21 from the open side (rear side) to the back side (front side), respectively. At this time, it is necessary to fit the protrusion 44c of each mount body 41 to the fitting recess 53b of the lower side wall 53 of each housing recess 51, respectively. Since the protrusion 44c of each mount body 41 is formed in a tapered shape at the front portion of the protrusion 44c, even if the radiator 1 is slightly displaced in the vehicle width direction with respect to the shroud 21, The projecting portion 44c is guided by the tapered shape into the fitting recess 53b and fitted into the fitting recess 53b. The radiator 1 is positioned in the vehicle width direction with respect to the shroud 21 when the fitting of the protrusion 44c into the fitting recess 53b is completed (when the insertion of the mount body 41 into the receiving recess 51 is completed). It will be.

  Further, the curved surface portion 44e of the projecting portion 44c makes it easy to place the inclined surface portion 44d following the curved surface portion 44e on the inclined surface of the receiving portion 57 when the mount main body 41 is inserted into the receiving recess 51. The tapered shape makes it easy to fit the protrusion 44c into the fitting recess 53b. Furthermore, the inclined surface portion 44d slides with respect to the upper surfaces of the ribs 53c and 53c during the insertion of the mount body 41 into the housing recess 51, but the curved surface portion 44e is lifted from the upper surfaces of the ribs 53c and 53c. Therefore, compared to the sliding resistance of the inclined surface portion 44a with respect to the upper surfaces of the ribs 53a and 53a in the first embodiment, the sliding resistance of the inclined surface portion 44d with respect to the upper surfaces of the ribs 53c and 53c can be reduced.

Further, portions other than the fitting recess 53b (portions on both sides of the fitting recess 53b) on the upper surface of the lower wall portion 53 of each housing recess 51 are the same height as the upper surfaces of the ribs 53a and 53a described in the first embodiment. It has the same shape at the position, and the inclined surface portion 44a contacts. However, basically, the ribs of the bottom surface of the fitting recess 53 b 53c, the upper surface of the 53c, it constitutes a receiving portion 57 of the installation unit 50, for supporting the lower surface of the mount body 41. A portion other than the fitting recess 53 b on the upper surface of the lower wall portion 53 constitutes a receiving portion 57 of the installation portion 50 in an auxiliary manner.

  On the upper surface of each mount body 41 (the upper surface of the holding member 44), a clip portion 44f that engages with the shroud 21 when the mount body 41 is installed on the installation portion 50 is provided (FIGS. 9 and 11). And FIG. 13). An engagement recess 52b is formed on the upper side wall 52 of each receiving recess 51 corresponding to the clip 44f. In the present embodiment, the upper side wall portion 52 and the front side wall portion 54 are not provided with the ribs 52a and 54a as in the first embodiment. Further, the front side wall portion 54 is considerably on the front side compared to the first embodiment (it may be in the same front-rear position as in the first embodiment, and the same ribs 54a, 54a,... As in the first embodiment are provided. May be).

  The clip portion 44 f has an extending portion 44 g that extends to the rear side immediately after extending upward from a substantially central portion in the front-rear direction on the upper surface of the holding member 44. The extending portion 44g has flexibility and can be bent downward. An engaging portion 44h that engages with the engaging recess 52b is provided in the vicinity of the rear end of the extending portion 44g. When the mount main body 41 is completely inserted into the housing recess 51, the engaging portion 44h is engaged with the engaging recess 52b so that the mount main body 41 is temporarily held by the shroud 21. Thereby, even if the fixing bracket 45 is not fixed to the shroud 21, the mount main body 41 is not detached from the accommodating recess 51.

  A rear portion of the extending portion 44g from the engaging portion 44h extends to the rear side of the fixing bracket 45, and is an operation portion 44i that can be operated by the operator. When the operator presses the operation portion 44i downward, the extended portion 44g bends downward, so that the engagement between the engagement portion 44h and the engagement recess 52b is released. Thus, when the radiator 1 is replaced with a new one, the mount body 41 can be removed from the housing recess 51 by operating the operation portion 44i. A stopper 44j for preventing the extended portion 44g from abutting on the lower side of the extended portion 44g on the upper surface of the holding member 44 and preventing the extended portion 44g from being bent excessively downward is provided. Is provided.

  Therefore, in the present embodiment, the same operational effects as those of the first embodiment can be obtained, and when the radiator 1 and the two mounting devices 40, 40 are assembled to the shroud 21, the mount main bodies 41 are respectively placed in the receiving recesses 51. It becomes easy to insert, and after the insertion is completed, the fixing bracket 45 is easily fixed to the shroud 21 by temporary holding by the clip portion 44f. Further, the positioning of the radiator 1 with respect to the shroud 21 in the vehicle width direction can be performed.

  The present invention is not limited to the first and second embodiments, and can be substituted without departing from the scope of the claims.

  For example, in the first and second embodiments, the housing recesses in which the mount bodies 41 of the mounting devices 40 are housed and installed at positions above the vehicle body fixing portion 28 on the rear surface of the side walls 24 of the shroud 21. 51 (installation portion 50) is provided, and a fixing bracket 45 is provided on the rear side of the mount body 41 of each mounting device 40. From the vehicle body fixing portion 28 on the front surface of each side wall portion 24 of the shroud 21, Further, an installation section 50 on which the mount main body 41 of each mount device 40 is respectively installed may be provided at an upper position, and a fixing bracket 45 may be provided on the front side of the mount main body 41 of each mount device 40. In this case, each side wall portion 24 of the shroud 21 is formed with an insertion hole that allows each protrusion 11 to be inserted from the rear side of the shroud 21 and positioned on the front side of the shroud 21. And each mounting part 40 is located in each installation part 50 in the surface of the front side of each side wall part 24 of the shroud 21 through each said insertion hole in the state which does not attach the mounting apparatuses 40 and 40 to the protrusion parts 11 and 11.
