  As shown in FIG. 3, the curtain shield airbag 40 is accommodated between the roof side rail 12 and the roof head lining 21 along the longitudinal direction of the vehicle in a state of being folded in a cylindrical shape. The curtain shield airbag 40 is a type of SRS (Supplemental Restraint System) of a vehicle. The curtain shield airbag 40 protects an occupant from a car window or the like by expanding the roof head lining 21 so as to hang down while pushing the roof head lining 21 inward during a vehicle collision.

  The bracket 50 is a steel member fixed to the roof side rail 12 located at the left end of the vehicle. In the present embodiment, the bracket 50 is fixed to the roof side rail 12 using a fastening member such as a screw. As shown in FIGS. 2 and 3, the curtain shield airbag 40 is attached to the bracket 50 so as to be held from the inside of the vehicle. The bracket 50 promotes the normal deployment of the curtain shield airbag 40 by regulating the deployment direction of the curtain shield airbag 40 in addition to supporting the curtain shield airbag 40. As shown in FIGS. 2 and 3, a gap is formed between the bracket 50 and the roof side rail 12, and the liquid tube 32 and the suction tube 33 pass through the gap while bending together. As shown in FIG. 9, the bracket 50 has an opening 51. The opening 51 is provided through the bracket 50 in the vehicle width direction. The opening 51 supports the socket 36.

  The ceiling drainage pipe 34 is connected to the drainage port 316 of the air conditioner 31 and the inflow portion 361 (details will be described later) of the socket 36, as shown in FIGS. 2 and 3. Condensed water discharged from the drainage port 316 flows down to the socket 36 in the ceiling drainage pipe 34. The ceiling drainage pipe 34 is made of, for example, EPDM (ethylene-propylene-diene rubber), and is formed by injection molding. The ceiling drain 34 has one end 341 and the other end 342. One end 341 is connected to the drainage port 316 and covers the drainage port 316 in the circumferential direction. The other end 342 is located opposite to the one end 341 in the lengthwise direction x of the ceiling drainage pipe 34. The ceiling drainage pipe 34 passes between the roof head lining 21 and the curtain shield airbag 40 in the vertical direction of the vehicle.

As shown in FIG. 1, the side drainage pipe 35 extends downward from the vehicle as in the case of the center pillar 13, and then extends below the floor panel 14 below the vehicle. The side drainage pipe 35 is made of a material that is more rigid than the ceiling drainage pipe 34. The side drainage pipe 35 has an upper end 351 located at the upper end thereof and a lower end 352 located opposite to the upper end 351. As shown in FIG. 3, the upper end portion 351 penetrates the pillar inner panel 132 and is connected to the outflow portion 362 (details will be described later) of the socket 36. As shown in FIG. 1, the lower end portion 352 penetrates the floor panel 14 toward the lower side of the vehicle. The condensed water drained from the inflow portion 361 of the air conditioner 31 and flowing down the ceiling drainage pipe 34 flows down from the upper end 351 to the side drainage pipe 35 via the socket 36. The condensed water which has flowed down the side drain pipe 35 is drained from the lower end portion 352 to the outside of the vehicle.

  The socket 36 is supported by the opening 51 of the bracket 50 and interconnects the other end 342 of the ceiling drainage pipe 34 and the upper end 351 of the side drainage pipe 35, as shown in FIGS. 2 and 3. ing. The socket 36 is made of, for example, POM (polyoxymethylene resin (polyacetal resin)). The socket 36 is located between the bracket 50 and the pillar inner panel 132 (center pillar 13) in the vehicle width direction. As shown in FIGS. 3, 7 and 9, the socket 36 has an inflow portion 361, an outflow portion 362 and a support portion 363.

  As shown in FIGS. 3, 7 and 9, the inflow portion 361 is a box-shaped opening to which the other end 342 of the ceiling drainage pipe 34 is connected. When the other end 342 is connected to the inflow portion 361, the flange 343 of the ceiling drainage pipe 34 is located at the inflow portion 361. The inflow portion 361 is located below the drainage port 316 of the air conditioner 31 in the vehicle. For this reason, the ceiling drainage pipe 34 is inclined downward from the drainage port 316 toward the inflow portion 361 so that the condensed water discharged from the inflow portion 361 can flow down by gravity. As shown in FIGS. 3 and 9, the outflow portion 362 is a tubular portion located on the opposite side of the inflow portion 361 in the vehicle width direction. The upper end 351 of the side drain pipe 35 is connected to the outflow portion 362. As shown in FIGS. 7 and 9, the support portion 363 is a U-shaped portion surrounding a part of the inflow portion 361 as viewed in the vehicle width direction. A part of the support portion 363 above the vehicle is open. The support portion 363 has an outer edge portion 363A and an inner edge portion 363B. The outer edge portion 363A is located at the outer edge of the support portion 363 as viewed in the vehicle width direction. The lower edge of the opening 51 of the bracket 50 is in contact with the outer edge portion 363A. The inner edge portion 363B is located at the inner edge of the support portion 363 as viewed in the vehicle width direction. The inner edge portion 363 B faces the other end 342.

  The connection member 37 is fixed to the other end 342 of the ceiling drainage pipe 34 as shown in FIGS. 3, 6, 9 and 10. The connecting member 37 connects the other end 342 to the inflow portion 361 of the socket 36 by engaging with the inner edge portion 363 B of the support portion 363 of the socket 36. In the drainage structure A, the connection member 37 contacts the flange 343 from the one end 341 to the other end 342 in the length direction x of the ceiling drainage pipe 34. Further, in the drainage structure A, the connection member 37 is annular. The shape of the connection member 37 is not limited to this, and may be any shape as long as it is fixed to the other end 342 and engaged with the socket 36. For example, the connection member 37 may be semicircular. The connection member 37 has an outer circumferential surface 371, an inner circumferential surface 372, a contact surface 373 and an engagement groove 374. The outer circumferential surface 371 faces the outside of the connection member 37 in the radial direction r of the ceiling drainage pipe 34. The inner circumferential surface 372 faces the opposite side to the outer circumferential surface 371 and is in contact with the other end 342. The contact surface 373 faces the ceiling drainage pipe 34 in the lengthwise direction x and is in contact with the flange 343. The engagement groove 374 is recessed from the outer peripheral surface 371 in the radial direction r of the ceiling drainage pipe 34 and extends along the outer peripheral surface 371. In the drainage structure A, the engagement groove 374 is formed over the entire circumference of the outer circumferential surface 371. The engagement groove 374 is engaged with the inner edge 363 B of the support 363. Connecting member 37 is made of, for example, POM. When the ceiling drainage pipe 34 is formed by injection molding in a state where the connection member 37 formed in advance is disposed in the mold, the connection member 37 is fixed to the other end 342. When the connecting member 37 is fixed to the other end 342, the inner circumferential surface 372 is adhered to the other end 342 and the contact surface 373 is adhered to the flange 343.

  As shown in FIG. 8, in the drainage structure A, with the engagement groove 374 of the connection member 37 engaged with the inner edge portion 363 B of the support portion 363 of the socket 36 from above the vehicle, the connection member 37 is directed downward Move. Thus, the other end 342 of the ceiling drainage pipe 34 is connected to the inflow portion 361 of the socket 36.

  As shown in FIG. 3, FIG. 6, FIG. 9 and FIG. 10, the ceiling drainage pipe 34 is provided with an easy cutting portion 344 in the vicinity of the connection member 37. Here, the vicinity of the connection member 37 means, as shown in FIG. 10, the surface of the connection member 37 facing the one end 341 of the ceiling drainage pipe 34 and the ceiling drainage pipe 34 in the length direction x of the ceiling drainage pipe 34. It refers to the range of the section L extending from the boundary toward one end 341. The section L has a length substantially equal to the outer diameter of the ceiling drainage pipe 34. In the drainage structure A, the length of the section L is 15 mm. The easy cutting portion 344 may be cut when the curtain shield airbag 40 is deployed due to a vehicle collision and the curtain shield airbag 40 contacts the ceiling drainage pipe 34. In the drainage structure A, the easy-to-cut portion 344 is a continuous ditch formed along the entire circumference of the ceiling drainage pipe 34. Note that, as shown in FIG. 11, the easy-to-cut portion 344 may be a plurality of recessed grooves formed along the entire circumference of the ceiling drainage pipe 34 and in which two adjacent ones are separated from each other.

  Next, the operation and effect of the drainage structure A will be described.

  The ceiling drainage pipe 34 constituting the drainage structure A is provided with an easy-to-cut portion 344 which can be cut when the curtain shield airbag 40 contacts the ceiling drainage pipe 34 in the vicinity of the connection member 37. The connecting member 37 is fixed to the other end 342 of the ceiling drainage pipe 34 and engages with the socket 36 to connect the other end 342 to the inflow portion 361 of the socket 36. When the curtain shield airbag 40 is deployed due to a vehicle collision, the curtain shield airbag 40 contacts the ceiling drainage pipe 34. At this time, the ceiling drainage pipe 34 is cut by the easy cutting portion 344, and the other end 342 remains left in the connection member 37. Therefore, according to the drainage structure A, it is possible to prevent the end (the other end 342) of the cut ceiling drainage pipe 34 from scattering into the vehicle with the deployment of the curtain shield airbag 40.

  The other end 342 of the ceiling drainage pipe 34 is provided with a flange 343 extending in the radial direction r. The flange 343 is in contact with the contact surface 373 of the connection member 37. When the curtain shield airbag 40 comes in contact with the ceiling drainage pipe 34, the ceiling drainage pipe 34 is cut at the easy cutting portion 344 and the other end 342 tends to be pulled inside the vehicle. Therefore, when the flange 343 contacts the contact surface 373, the other end 342 can be more reliably prevented from falling off the connecting member 37.

  The ceiling drainage pipe 34 is disposed in a meandering manner as viewed from above the vehicle. Thereby, when the curtain shield airbag 40 is developed, the area of the ceiling drainage pipe 34 in contact with the curtain shield airbag 40 can be further expanded. Therefore, deployment of the curtain shield airbag 40 becomes smoother.

  The present invention is not limited to the embodiments described above. The specific configuration of each part of the present invention can be varied in design in many ways.
