-Brake hose bracket-
Next, the brake hose bracket 1 will be described in detail. FIG. 3 is a perspective view schematically showing the brake hose bracket 1, and FIG. 4 is an enlarged view schematically showing a connecting portion 50 between the brake hose 30 and the brake tube 40. As shown in FIG. 3, the brake hose bracket 1 is formed into a substantially L-shaped angle by bending a single metal plate. The brake hose bracket 1 has a substantially trapezoidal main body part 3 attached to the trailing arm 21 of the rear suspension 20, and a connection part 50 between the brake hose 30 and the brake tube 40, which is fixed to be orthogonal to the main body part 3. And a part 5.

As shown in FIG. 4, the substantially trapezoidal main body portion 3 has a posture in which a portion 3a corresponding to a short side is a front side in the vehicle front-rear direction and a portion 3b corresponding to a long side is a rear side in the vehicle front-rear direction. A portion 3c corresponding to the oblique side is welded to the vicinity of the brake tube 40 on the trailing arm 21 so as to be along the trailing arm 21 extending substantially in the vehicle front-rear direction. As a result, like the brake tube 40, the main body 3 extends substantially horizontally while inclining inward in the vehicle width direction (left side) as it goes forward from above the trailing arm 21. The hole 3e formed in the main body portion 3 is a hole corresponding to a weld nut for fixing a support member of a harness (not shown) passing near the brake hose bracket 1, and is also formed in the main body portion 3. The hole 3f is a hole into which the detent pin of the support member is inserted.

The fixed portion 5 extends upward from a tip end portion (a portion 3d corresponding to the other oblique side) of the main body portion 3 that extends in the substantially same direction as the brake tube 40 from above the trailing arm 21. They are almost orthogonal. As shown in FIG. 3, a substantially oval mounting hole 6 is penetratingly formed in the fixing portion 5. The brake hose 30 and the brake tube 40 are inserted into the mounting hole 6 from the front side, and the brake hose 30 and the brake tube 40 are fixed to the fixing portion 5 by the substantially U-shaped clip 36 shown in FIG. The tubes 40 are connected by screwing the front end portion 40a from the rear side, whereby the connecting portion 50 between the brake hose 30 and the brake tube 40 is fixed to the fixing portion 5.

FIG. 5 is a diagram schematically showing a connection structure between the brake hose 30 and the brake tube 40. More specifically, a fitting 31 is attached to the rear end 30a of the brake hose 30, as shown in FIG. The fitting 31 has a flange portion 32 larger than the mounting hole 6 formed in the fixed portion 5, and a fitting portion having the same shape and the same size as the mounting hole 6 protruding from the flange portion 32 toward the tip (rear end) side. 33, a substantially cylindrical female screw connection portion 35 in which a female screw is formed on the inner peripheral surface, and an outer diameter larger than that of the female screw connection portion 35 formed between the fitting portion 33 and the female screw connection portion 35. Has a small columnar constriction 34.

On the other hand, a fastening member 41 is attached to the front end portion 40a of the brake tube 40 by double flare processing so as not to slip out of the brake tube 40. The fastening member 41 has a nut portion 42 and a cylindrical portion 43 formed integrally with the nut portion 42. A male screw is formed on the outer peripheral surface of the tip portion of the cylindrical portion 43.

When connecting the rear end portion 30a of the brake hose 30 and the front end portion 40a of the brake tube 40 configured as described above, first, the female screw connection portion 35 is inserted into the mounting hole 6 of the fixing portion 5 from the front side. At the same time, the fitting portion 33 having the same shape and size as the mounting hole 6 is fitted into the mounting hole 6. By thus fitting the fitting portion 33 into the mounting hole 6, the rear end portion 30a of the brake hose 30 is positioned.

Then, the substantially U-shaped clip 36 shown in FIG. 2 is inserted from above into the constricted portion 34 protruding from the mounting hole 6 to the rear side, as shown in FIG. In this way, by inserting the clip 36 into the constricted portion 34, the fixing portion 5 is sandwiched by the flange portion 32 and the clip 36, whereby the rear end portion 30a of the brake hose 30 is fixed to the fixing portion 5. To be done.

Next, while fixing the brake tube 40 with a jig (not shown), the nut portion 42 is turned to screw the distal end portion of the cylindrical portion 43 on which the male screw is formed into the female screw connecting portion 35. As a result, the brake hose 30 and the brake tube 40 are connected, and the connecting portion 50 between the brake hose 30 and the brake tube 40 is fixed to the fixing portion 5.

By the way, most of the metal brake tube 40 is covered with the rubber protector 45 (hatched portion in FIG. 4) as described above. However, regarding the front end portion 40a connected to the brake hose 30, Since it is necessary to rotatably attach the fastening member 41 and to secure a grip allowance of the jig when turning the nut portion 42, it is difficult to cover with the protector 45. Therefore, the front end portion 40a of the brake tube 40, in other words, the portion near the connecting portion 50 is in a state where the metal is exposed.

Here, in order to facilitate understanding of the present embodiment, a conventional brake hose bracket 101 will be described. FIG. 5: is a figure which shows the conventional brake hose bracket 101 typically. Similar to the brake hose bracket 1 of the present embodiment, the conventional brake hose bracket 101 also has a main body 103 mounted on the trailing arm 121 and a fixed part 105 to which the connecting part 150 is fixed. .. However, the conventional brake hose bracket 101 was considered to simply connect the brake hose 130 and the brake tube 140 and support the connecting portion 150. In other words, it was considered that only the fixed portion 105 needs to be located near the connecting portion 150.

Therefore, while the brake tube 140 extends obliquely inward in the vehicle width direction from the top of the trailing arm 121, the main body 103 extends substantially inward in the vehicle width direction from above the trailing arm 121. In addition, when viewed in the up-down direction, the brake tube 140 had such a shape that only the portion of the brake tube 140 not covered by the protector 145 and the part of the main body 103 overlap. Therefore, as shown in FIG. 6, a gap G is formed between the brake hose bracket 101 and the intermediate beam 122, and a portion of the brake tube 140 that is not covered with the protector 145 is exposed when viewed from below. It was Therefore, in the conventional brake hose bracket 101, bounced flying stones or the like pass through the gap G between the intermediate beam 122 and the brake hose bracket 101 and hit an uncovered portion of the brake tube 140 in the vicinity of the connecting portion 150, so that the brake The tube 140 might be damaged.

Therefore, in the present embodiment, the brake hose bracket 1 that supports the connecting portion 50 between the brake hose 30 and the brake tube 40 has a role of protecting the brake tube 40.

Specifically, as described above, the main body portion 3 is extended from above the trailing arm 21 in substantially the same direction as the brake tube 40, and the portion of the brake tube 40 that is not covered by the protector 45 is not exposed when viewed from below. Thus, the main body 3 is formed so as to cover the lower side of the brake tube 40. In other words, the trailing arm extends from the fixed portion 5 to which the connecting portion 50 is fixed toward the trailing arm 21 side in a direction substantially the same as the extending direction of the brake tube 40 so as to cover the lower side of the brake tube 40. The body portion 3 is formed so as to be attached to the body 21.

In this way, the main body 3 of the brake hose bracket 1 faces the trailing arm 21 so as to cover the lower portion of the brake tube 40 from the fixed portion 5 to which the connection portion 50 between the brake hose 30 and the brake tube 40 is fixed. Since it is extended, the main body portion 3 can receive flying stones and the like that have come near the connection portion 50 of the brake tube 40.

Moreover, since the main body portion 3 extends substantially in the same direction as the extension direction of the brake tube 40, the lower portion of the brake tube 40 can be covered without making the main body portion 3 larger than necessary.

As described above, according to the present embodiment, it is possible to suppress the bounced rocks and the like from hitting a portion in the vicinity of the connection portion 50 that is not covered by the protector 45 with a simple configuration without waste, and thereby, It is possible to prevent the brake tube 40 from being damaged.
