In addition, the inlet pipe 20 has its proximal end locked and connected to the washer tank 10, and its distal end locked to the hole 5 a (both indicated by a two-dot chain line) of the deck panel 5. In addition, an inlet 26 for injecting a washer liquid is formed on the distal end side of the inlet pipe 20. In addition, the inlet pipe 20 has a distal end located at the foremost and upper side, and a proximal end located at the rearmost and the right side.

  The inlet pipe 20 includes a proximal end side pipe portion 21 that is a proximal end side pipe portion and a distal end side pipe portion 25 that is a distal end side pipe portion. The proximal end pipe portion 21 has an axis C that coincides with the cylinder axis C of the opening 11 (see FIG. 2 for both). The distal end side pipe 25 is formed by being bent from the proximal end side pipe portion 21 in a direction intersecting the axis C. Here, a description will be given of the distal end side pipe 25 bent forward and upward with respect to the axis C of the proximal end side pipe portion 21.

The inlet pipe 20 is attached to the washer tank 10 after being rotated by a predetermined angle θ in a predetermined rotation direction about the axis C as a rotation axis. Here, a case where the predetermined rotation direction is counterclockwise will be described.
The proximal end side pipe part 21 has a linear hollow shaft part 22 having a protrusion 22a and a claw part 22b, a flange part 23, and a handle part 24 in this order from the proximal end. These linear hollow shaft portion 22, flange portion 23, and handle portion 24 all have a common axis C.

  The linear hollow groove portion 22 is a portion inserted through the opening portion 11 (see FIG. 2). The linear hollow groove portion 22 has an outer diameter smaller than the opening 11p (see FIG. 2) formed by the opening portion 11, and a protrusion 22a is formed on the outer periphery. The protruding portion 22a is a portion protruding along a direction orthogonal to the axis C, or a male screw-like protruding portion slightly inclined from the direction orthogonal to the axis C. Further, a claw portion 22b is formed on the tip side (the vehicle left side) upper portion than the protruding portion 22a. The protrusions 22a and the claw portions 22b will be described in detail in the locking mechanism α described later.

  The flange portion 23 is a flange-shaped portion that is formed on the distal end side (the vehicle left side) of the linear hollow groove portion 22 and projects from the cylindrical portion of the proximal end-side pipe portion 21 in the diameter increasing direction over the entire circumference. is there. The flange portion 23 is a portion that comes into contact with the opening portion 11 from the left when the linear hollow groove portion 22 is inserted through the opening portion 11 (see FIG. 2). That is, the flange part 23 functions as what regulates the insertion depth of the linear hollow groove part 22 into the opening part 11.

The handle portion 24 is a portion projecting so as to expand the diameter in the front-rear direction of the proximal end side pipe portion 21. The handle portion 24 is used when an operator rotates the inlet pipe 20 in a predetermined rotation direction when the inlet pipe 20 is attached to the washer tank 10 (see FIGS. 1 and 2).
The distal end side pipe portion 25 is formed with an inlet 26 and a locking portion 27 at the distal end portion thereof.

The inlet 26 is an opening formed at the tip of the inlet pipe 20, and is located in the upper part of the engine room 1 (see FIG. 1) with the inlet pipe 20 attached to the washer tank 10.
The locking part 27 is a part for locking the inlet pipe 20 to the deck panel 5. The locking portion 27 has flexibility. For this reason, the inlet pipe 20 has a nominal design that allows manufacturing errors, errors in mounting positions, and the like of parts related to the inlet pipe mounting structure of the present embodiment including the hole 5a and the locking portion 27.

The locking part 27 is a part protruding from the distal end side pipe part 25. In FIG. 3, the latching | locking part 27 shows what protruded from the left side surface right under the front-end | tip of the front end side pipe part 25. FIG.
Specifically, the locking portion 27 includes an arm portion 27a that protrudes from the distal end side pipe portion 25 and a protrusion portion 27b that protrudes from the distal end portion of the arm portion 27a.
The arm part 27a is an L-shaped projecting piece in front view (top view). For example, the arm portion 27a as viewed from the side has a forward-declining slope. The arm portion 27a shown in FIG. 3 protrudes leftward of the vehicle from directly below the distal end of the distal end side pipe portion 25, and protrudes rearward (distal end) from this protruding end.

The protruding portion 27b is a protruding portion formed at the tip of the arm portion 27a. In FIG. 3, a rectangular parallelepiped protrusion is shown as the protrusion 27b.
The projection 27b is attached by being inserted into a hole 5a (both indicated by a two-dot chain line) formed at the front edge of the deck panel 5. That is, the hole part 5a is a part which forms the square hole of the shape corresponding to the projection part 27b. Here, the protrusion 27b has a rectangular parallelepiped shape and the hole 5a has been described as a square hole corresponding to the protrusion 27b. However, the protrusion 27b and the hole 5a are, for example, a cylindrical portion and It may be a portion that forms a corresponding round hole, and is formed in a shape corresponding to the protrusion 27b so that the protrusion 27b can be locked to the hole 5a when the protrusion 27b is inserted into the hole 5a. It only has to be.

  In a state where the protruding portion 27 b is attached to the hole portion 5 a of the deck panel 5, the arm portion 27 b is pressed against the deck panel 5. In other words, the locking portion 27 is bent so that the tip portion where the protruding portion 27b is formed is pushed down in a state where the protruding portion 27b is attached. On the other hand, the protrusion 27b is inserted into the hole 5a of the deck panel 5 at the front end of the engaging portion 27 (shown by a two-dot chain line) before the protrusion 27b is attached to the hole 5a of the deck panel 5. It is located above the tip of the locking part 27.

  As described above, when the locking portion 27 is pressed against the deck panel 5, the inlet pipe 20 is biased with a counterclockwise rotational force with the axis C as the rotational axis. In other words, when the engaging portion 27 of the distal end side pipe portion 25 is engaged with the deck panel 5, the deck panel 5 presses the proximal end side pipe portion 21 counterclockwise through the distal end side pipe 25.

  Next, the locking mechanism α that locks the inlet pipe 20 to the washer tank 10 will be described with reference to FIG. This locking mechanism α is a mechanism provided between the linear hollow groove portion 22 of the inlet pipe 20 and the opening portion 11 of the washer tank 10.

  The locking mechanism α includes a protrusion 22a and a claw 22b formed in the straight hollow groove 22 of the inlet pipe 20, and a groove 11a and a claw receiving portion 11b formed in the opening 11 of the washer tank 10. It works by working. In this locking mechanism α, locking by the protrusion portion 22a and the groove portion 11a formed corresponding thereto (hereinafter referred to as “groove locking”), and the claw portion 22b and correspondingly formed. Locking with the claw receiving portion 11b (hereinafter referred to as “claw locking”) functions.

First, a configuration relating to groove locking of the locking mechanism α will be described.
The ridge portion 22a and the groove portion 11a are formed in shapes corresponding to each other so as to be fitted into the groove when the inlet pipe 20 is rotated by a predetermined angle θ counterclockwise about the axis C as a rotation axis. That is, each of the protrusion 22a and the groove 11a is formed with a groove or groove receiver having a predetermined angle θ with respect to at least the axis C.
When the protrusion 22a (shown by a broken line) before the inlet pipe 20 is locked to the washer tank 10 is rotated by a predetermined angle θ, the protrusion 22a (shown by a two-dot chain line) and the groove 11a (shown by a broken line) And the groove locking function.

Next, a configuration related to the claw locking of the locking mechanism α will be described.
The claw portion 22 b is a portion that protrudes from the top of the straight hollow groove portion 22 on the tip side. The claw receiving portion 11b is a portion that comes into contact when the claw portion 22b is inserted into the opening 11p and rotated counterclockwise by a predetermined angle θ.
The opening 11p can be divided into a round hole-shaped lower opening 11d through which a pipe part forming a hollow in the linear hollow groove part 22 can be inserted, and a keyhole-shaped upper opening 11u through which the claw part 22b can be inserted and removed. The upper opening 11u is formed larger than the claw portion 22b in a side view.

Inside the opening 11 that forms the upper opening 11u, an internal space 11s is formed in which the rear end position coincides with the upper opening 11u and the length in the front-rear direction is longer than that of the upper opening 11u.
The internal space 11 s is surrounded by the opening 11 on the left and right sides and the front. That is, the internal space 11s is a space in which the claw portion 22b inserted into the upper opening 11u can rotate forward. The internal space 11s has a length in the front-rear direction where the claw portion 22b comes into contact when the inlet pipe 20 is rotated counterclockwise by a predetermined angle θ about the axis C as a rotation axis.

The thickness (length in the vehicle width direction) of the opening 11 on the side (here, the left side) where the inlet pipe 20 is mounted with respect to the internal space 11s is defined by the claw portion 22b and the flange portion 23 (see FIG. 3). It is set to be approximately equal to or slightly longer than the distance.
The claw receiving portion 11b is a portion of the opening 11 that surrounds the left side and the front of the opening 11 that surrounds the internal space 11s. Therefore, when the claw portion 22b is inserted into the upper opening 11u and the inlet pipe 20 is rotated counterclockwise by a predetermined angle θ about the axis C as the rotation axis, the claw portion 22b (shown by a two-dot chain line) is moved to the claw receiving portion 11b. And the movement along the axis C are restricted by the claw receiving portion 11b.
For example, the claw portion 22b and the claw receiving portion 11b are formed like a key and a keyhole.

[Action and effect]
The inlet pipe mounting structure according to one embodiment of the present invention is configured as described above. Next, the attachment of the inlet pipe 20 to the washer tank 10 will be described with reference to FIGS. In FIGS. 5A to 5C, reference numerals are given only to the portions touched in the following description.

First, as shown in FIG. 5A, the axis C of the base end side pipe portion 21 of the inlet pipe 20 is made to coincide with the cylinder axis C of the opening 11 of the washer tank 10. Then, the linear intermediate shaft portion 22 of the proximal end side pipe portion 21 is inserted (inserted) into the opening portion 11.
When the straight intermediate shaft portion 22 is inserted into the opening portion 11, the flange portion 23 of the inlet pipe 20 abuts from the left side of the opening portion 11 as shown in FIG. That is, the insertion depth of the linear intermediate shaft portion 22 into the opening 11 is restricted. Then, the inlet pipe 20 is rotated counterclockwise about the axis C as the rotation axis. At this time, an operator or the like can rotate the inlet pipe using the handle portion 24.

  When the inlet pipe 20 is rotated by a predetermined angle θ, as shown in FIG. 5C, in the locking mechanism α, the protruding portion 22a and the groove portion 11a (both see FIG. 4) cooperate to form the groove engagement. The claw portion 22b and the claw receiving portion 11b (see FIG. 4) cooperate to engage with the claw. As a result, the inlet pipe 20 is locked to the washer tank 10. At this time, although the deck panel 5 is not yet attached, the inlet pipe 20 is temporarily fixed in a state where it does not come off from the washer tank 10 and does not come off due to groove locking and claw locking by the locking mechanism α. . The temporarily fixed inlet pipe 20 extends the flow path of the washer liquid flowing into the opening 11 of the washer tank 10 forward and upward.

After the deck panel 5 is attached, the locking portion 27 of the inlet pipe 20 is bent and the protrusion 27a of the locking portion 27 is inserted into the hole 5a of the deck panel 5 as shown in FIG. Thus, the protrusion 27a is locked to the hole 5a. That is, the main fastening operation of the inlet pipe 20 is completed only by locking the projection 27a in the hole 5a.
In this way, the installation of the inlet pipe 20 is completed.

  Therefore, according to the inlet pipe mounting structure of the present invention, when the locking portion 27 of the distal end side pipe portion 25 is locked to the deck panel 5, the deck panel 5 passes through the distal end side pipe portion 25 and the proximal end side pipe portion 25. Is pushed counterclockwise, that is, the deck panel 5 presses the inlet pipe 20 so as to prevent the locking of the inlet pipe 20 to the washer tank 10 by the locking mechanism α. The inlet pipe 20 can be reliably locked.

Further, since the distal end side pipe portion 25 bent from the proximal end side pipe portion 21 in the direction intersecting the axis C of the linear hollow shaft portion 22 has the arm portion 27 locked to the deck panel 5, the inlet pipe 20 is bent and the front end side of the inlet pipe 20 is locked to the deck panel 5. Therefore, even if the upper opening of the engine room 1 is small, the upper portion of the inlet pipe 20 can be locked and fixed at an appropriate location on the deck panel 5. Therefore, even if the upper opening of the engine room 1 is small and the layout in the engine room 1 is severely limited, the upper part of the inlet pipe 20 can be locked by shifting the inlet 26 forward. it can.
Thus, even when the upper opening of the engine room 1 is small, the inlet pipe 20 can be reliably fixed.

  Further, between the straight hollow shaft portion 22 of the proximal end side pipe portion 21 and the opening portion 11 of the washer tank 10 in the inlet pipe 20, the straight hollow shaft portion 22 inserted through the opening portion 11 is counterclockwise. Since the locking mechanism α for locking the linear hollow shaft portion 22 to the opening portion 11 is provided by rotating by the predetermined angle θ, the inlet pipe 20 can be easily locked to the washer tank 10. .

  When the linear hollow shaft portion 22 is inserted through the opening 11, the claw portion 22b is inserted into the upper opening 11u. When the linear hollow shaft portion 22 is rotated counterclockwise by a predetermined angle θ, the claw portion 22b comes into contact with the claw receiving portion 11b, and the claw receiving portion 11b moves in the direction along the axis C of the claw portion 22b. Movement is restricted. Therefore, simply inserting the claw portion 22b into the upper opening 11u and rotating it allows the claw receiving portion 11b to function as a rotation stopper and a retaining stopper for the inlet pipe 10 and to easily lock the inlet pipe 20 to the washer tank 10. it can. Therefore, before the deck panel 5 is attached, the inlet pipe 20 can be easily temporarily fixed.

  Since the locking portion 27 of the inlet pipe 20 has flexibility, the pressing force transmitted from the deck panel 5 through the locking portion 27 to the inlet pipe 20 can be smoothly transmitted. Further, it is possible to allow manufacturing errors and mounting position errors of the inlet pipe 20, the deck panel 5, and the hole 5a. Therefore, it is possible to ensure the accuracy of the position where the inlet pipe 20 is fixed to the deck panel 5.

  The inlet pipe 20 can be locked to the deck panel 5 simply by inserting the protruding portion 27 b of the locking portion 27 into the hole 5 a of the deck panel 5. Since the projection 27b is formed in the locking portion 27 having flexibility, it is easy to align the projection 27b with the position of the hole 5a of the deck panel 5. Therefore, the accuracy of the attachment position of the inlet pipe 20 can be ensured.

  In order to lock the temporarily-fastened inlet pipe 20 to the deck panel 5, all that is required is to insert the protrusion 27b of the locking portion 27 into the hole 5a of the deck panel 5. Compared with the case where the pipe 20 is fixed to the body member, it is possible to reduce the burden of the main fastening operation of the inlet pipe 20.
