By the way, in such a vehicle wiper, when the wiper arm is fixed to the clip or when the wiper arm is released, a large load is applied to the engaging portion of the locking member, so that the engaging portion of the locking member is likely to undergo plastic deformation.

A connecting member for a vehicle wiper to solve the above problem is housed in a housing hole formed in a lever of a wiper blade constituting a vehicle wiper, and rotatably supports a shaft portion in the housing hole. and a resin connecting member rotatably connecting the lever to the wiper arm, the connecting member having a pair of side walls extending opposite to each other, and connecting the pair of side walls to each other and being connected to the tip of the wiper arm. a main body portion including a connecting portion that rotatably supports the shaft portion, a shaft hole that rotatably supports the shaft portion, and a slit that opens a part of a peripheral wall of the shaft hole; and the wiper arm is fixed to the main body portion. a fixing member, the main body portion has a bearing portion extending along the central axis of the shaft hole at an end closer to the proximal end in the extending direction of the wiper arm than the shaft hole; The fixed member includes a rotation shaft rotatably supported by the bearing portion, a pair of arms extending from the rotation shaft, an operation portion connected to the tips of the pair of arms, and the operation portion. The wiper arm has an engaging portion that protrudes from the wiper arm and elastically engages with the distal end portion of the wiper arm.

In order to fix the wiper arm to the main body, when the fixing member is rotated about the rotation axis in a direction in which the engaging portion approaches the main body, the engaging portion comes into contact with the tip of the wiper arm. When the fixing member is further rotated from this state, the engaging portion elastically engages with the tip of the wiper arm and stress is generated on the fixing member. Here, according to the above configuration, the stress is absorbed by the pair of arm portions connecting the rotating shaft and the engaging portion being elastically deformed and extended. Therefore, stress acting on the engaging portion can be reduced, and plastic deformation of the engaging portion can be suppressed.

When the fixing member is further rotated, the connecting portion and the tip of the wiper arm are sandwiched between the rotating shaft and the engaging portion in the extending direction of the lever. This fixes the wiper arm to the main body.

Further, when the fixing member is rotated about the rotation axis in a direction in which the engaging portion moves away from the main body portion in order to release the fixation of the wiper arm, stress is generated in the fixing member. Here, according to the above configuration, the stress is absorbed by the pair of arm portions being elastically deformed and extended. Therefore, stress acting on the engaging portion can be reduced, and plastic deformation of the engaging portion can be suppressed.

In the connecting member for a vehicle wiper, the main body portion has a hooking shaft portion at an end opposite to the base end side in the extending direction of the wiper arm with respect to the shaft hole, and the locking shaft portion It is preferable that the device has a latching portion that is latched to the latching shaft portion.

According to this configuration, when the fixing member fixes the distal end of the wiper arm to the connecting portion, the hooking portion is hooked to the hooking shaft portion of the main body, so that the fixing member is fixed to the main body. Rotation will be regulated. Therefore, the wiper arm can be more reliably fixed to the main body by the fixing member.

In the vehicle wiper connection member, it is preferable that the locking shaft portion connects the pair of side walls.
According to the same configuration, a pair of side walls facing each other are connected by the hanging shaft portion. Therefore, the rigidity of the side walls can be increased, and separation of the side walls from each other can be suppressed. Therefore, the latching portion can be stably latched to the latching shaft portion.

In the above connection member for a wiper for a vehicle, the engaging portion protrudes from the proximal end side of the operating portion, the hooking portion protrudes from the distal end side of the operating portion, and the engaging portion protrudes from the distal end side of the operating portion. The part has a hook shape to be latched to the latching shaft part, and the fixing member connects the engaging part and the latching part and forms a space between the part and the operating part. It is preferable to have a connecting portion for

According to this configuration, when the engaging portion engages with the tip of the wiper arm, the connecting portion elastically deforms toward the space. At this time, the stress acting on the engaging portion is absorbed by the elastic deformation of the connecting portion. Therefore, stress acting on the engaging portion can be reduced, and plastic deformation of the engaging portion can be further suppressed.

The latching portion and the latching shaft portion are provided at positions where they interfere with each other when the fixing member rotates. Therefore, when latching the latching portion to the latching shaft, it is necessary to once elastically deform the latching portion to release the latching shaft.

In this regard, according to the above configuration, the latching portion can be moved in a direction approaching the engaging portion by utilizing the elastic deformation of the connecting portion, and the latching shaft portion can be released. When the wiper arm is fixed to the main body as the fixing member rotates, the engaging portion, connecting portion, and hooking portion that have been elastically deformed are restored, and the hook shape of the hooking portion is restored. The tip of the holder is now latched onto the latching shaft. Therefore, the latching portion can be easily latched to the latching shaft portion as the fixing member rotates.

In the above connection member for a wiper for a vehicle, it is preferable that the operating portion has a recess formed on a surface opposite to a surface from which the engaging portion protrudes.
According to this configuration, the operator can place his or her fingers on the side surface of the recess formed in the operating section when rotating and pushing the fixing member into the main body. This makes it difficult for the operator's fingers to slip on the operating section. Therefore, the fixing work using the fixing member can be easily performed.

According to the present invention, plastic deformation of the engaging portion can be suppressed.

The operation of this embodiment will be explained.
As shown in FIGS. 7(a) to (c), in order to fix the wiper arm 10 to the main body 31, the fixing member 40 is rotated around the rotation axis 41 in the direction in which the engaging part 44 approaches the main body 31. When rotated, the engaging portion 44 comes into contact with the mounting portion 13 of the wiper arm 10. When the fixing member 40 is further rotated from this state, the engaging portion 44 elastically engages with the mounting portion 13 of the wiper arm 10, and stress is generated on the fixing member 40. Here, according to the above configuration, the stress is absorbed by the pair of arm portions 42 connecting the rotating shaft 41 and the engaging portion 44 being elastically deformed and extended.

When the fixing member 40 is further rotated, the connecting portion 33 and the mounting portion 13 of the wiper arm 10 are sandwiched between the rotating shaft 41 and the engaging portion 44 in the extending direction L of the lever 21. Thereby, the wiper arm 10 is fixed to the main body portion 31.

Furthermore, when the fixing member 40 is rotated about the rotation shaft 41 in a direction in which the engaging portion 44 moves away from the main body portion 31 in order to release the fixation of the wiper arm 10, stress is generated in the fixing member 40. . Here, according to the above configuration, the stress is absorbed by the pair of arm portions 42 being elastically deformed and extended.

The effects of this embodiment will be explained.
(1) The main body portion 31 has a bearing portion 35 extending along the central axis of the shaft hole 34 at an end portion closer to the proximal end in the extending direction of the wiper arm 10 than the shaft hole 34 . The fixed member 40 includes a rotating shaft 41 rotatably supported by a bearing 35, a pair of arms 42 extending from the rotating shaft 41, and an operating section 43 connected to the tips of the pair of arms 42. , has an engaging portion 44 that protrudes from the operating portion 43 and elastically engages with the mounting portion 13 of the wiper arm 10.

According to such a configuration, the above-mentioned effects are achieved. Therefore, stress acting on the engaging portion 44 can be reduced, and plastic deformation of the engaging portion 44 can be suppressed.
(2) The main body portion 31 has a hooking shaft portion 36 at an end opposite to the base end side of the wiper arm 10 in the extending direction of the wiper arm 10 with respect to the shaft hole 34 . The fixing member 40 has a latching portion 45 that is latched to the latching shaft portion 36 .

According to such a configuration, in a state where the fixing member 40 fixes the mounting portion 13 of the wiper arm 10 to the connecting portion 33, the hooking portion 45 is hooked to the hooking shaft portion 36 of the main body portion 31. , rotation of the fixing member 40 with respect to the main body portion 31 is restricted. Therefore, the wiper arm 10 can be more reliably fixed to the main body part 31 by the fixing member 40.

(3) The hanging shaft portion 36 connects the pair of side walls 32 to each other.
According to this configuration, a pair of side walls 32 facing each other are connected by the hook shaft portion 36. Therefore, the rigidity of the side walls 32 can be increased, and separation of the side walls 32 from each other can be suppressed. Therefore, the latching portion 45 can be stably latched to the latching shaft portion 36.

(4) The engaging portion 44 protrudes from the base end side of the operating portion 43. The hook portion 45 protrudes from the tip side of the operating portion 43. The distal end of the hook portion 45 has a hook shape that is hooked onto the hook shaft portion 36 . The fixing member 40 has a connecting portion 46 that connects the engaging portion 44 and the hooking portion 45 and forms a space S between it and the operating portion 43 .

According to this configuration, when the engaging portion 44 engages with the mounting portion 13 of the wiper arm 10, the connecting portion 46 is elastically deformed toward the space S. At this time, the stress acting on the engaging portion 44 is absorbed by the elastic deformation of the connecting portion 46. Therefore, stress acting on the engaging portion 44 can be reduced, and plastic deformation of the engaging portion 44 can be further suppressed.

The latching portion 45 and the latching shaft portion 36 are provided at positions where they interfere with each other when the fixing member 40 rotates. Therefore, when latching the latching portion 45 to the latching shaft portion 36, it is necessary to first elastically deform the latching portion 45 to release the latching shaft portion 36.

In this regard, according to the above configuration, the latching part 45 can be moved in a direction approaching the engaging part 44 by utilizing the elastic deformation of the connecting part 46, and the latching shaft part 36 can be released. . When the wiper arm 10 is fixed to the main body part 31 as the fixing member 40 rotates, the elastically deformed engaging part 44, connecting part 46, and hooking part 45 are restored. The hook-shaped tip of the hook portion 45 comes to be hooked to the hook shaft portion 36. Therefore, the latching portion 45 can be easily latched to the latching shaft portion 36 as the fixing member 40 rotates.

(5) The operating portion 43 has a recess 43a formed on a surface opposite to the surface from which the engaging portion 44 protrudes.
According to this configuration, when rotating and pushing the fixing member 40 into the main body part 31, the operator can place his fingers on the side surface of the recess 43a formed in the operating part 43. This makes it difficult for the operator's fingers to slip on the operating section 43. Therefore, the fixing work using the fixing member 40 can be easily performed.

The pair of side walls 32 have a second contact portion 38 provided on the opposite side of the first contact portion 37 across the shaft hole 34 in the extending direction L. A first restricting protrusion 27 is provided on the inner surface of the pair of side wall portions 25b to restrict rotation of the connecting member 30 in the first direction X about the shaft portion 26 by contacting the first abutting portion 37. It is provided. The inner surfaces of the pair of side wall portions 25b are in contact with the second contact portion 38 to restrict the rotation of the connecting member 30 about the shaft portion 26 in the second direction Y, which is opposite to the first direction X. A second regulating protrusion 28 is provided. The first regulating protrusion 27 and the second regulating protrusion 28 are opposite to the opening 25a with respect to the shaft portion 26 in the height direction H, and are provided on both sides of the shaft portion 26 in the extending direction L. It is being

According to such a configuration, the first regulating protrusion 27 and the second regulating protruding part 28 are provided on the side opposite to the opening 25a with respect to the shaft portion 26 in the height direction H. This makes it difficult for the first regulating protrusion 27 and the second regulating protrusion 28 to interfere with the coupling member 30 when the coupling member 30 is inserted into the opening 25a of the main lever 22 and assembled. Furthermore, even if the connecting member 30 is in an inverted position so that the position of the first contact portion 37 and the position of the second contact portion 38 are swapped, the connecting member 30 is can be inserted and assembled.

Furthermore, in the posture where the connecting member 30 is inverted as described above, when the connecting member 30 rotates in the first direction By contacting the first restricting protrusion 27, rotation of the connecting member 30 in the first direction X is restricted. Further, when the connecting member 30 rotates in the second direction Y around the shaft portion 26 of the main lever 22, the first contact portion 37 of the main body portion 31 comes into contact with the second regulating protrusion 28 of the lever. Rotation of the connecting member in the second direction Y is restricted. Therefore, it becomes possible to share the wiper blade 20 and the connecting member 30 between right-hand drive vehicles and left-hand drive vehicles.

(7) The first contact portion 37 and the second contact portion 38 are provided on both of the pair of side walls 32. The first regulating protrusion 27 and the second regulating protrusion 28 are provided on both of the pair of side wall parts 25b.

(8) The first regulating protrusion 27 and the second regulating protrusion 28 have shapes that are perpendicular to the extending direction L and symmetrical with respect to a virtual plane V that includes the center of the shaft portion 26.
According to such a configuration, the manner in which the rotation of the connecting member 30 about the shaft portion 26 of the main lever 22 is restricted can be made the same regardless of the assembled posture of the connecting member 30 with respect to the main lever 22.
