DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A wiper with a heater for an automobile according to an embodiment of the present invention will be described with reference to FIGS. Reference numeral 3 denotes a wiper arm which supports the blade supporting member 2 at the distal end and is swung along a glass surface by a motor by a head 3a on the proximal end side. The blade supporting member 2 is provided with a pipe-shaped heater 7 in its longitudinal storage groove 7a.
The rubber blade 1 (see FIG. 3) in which
Supported by From the intermediate portion 2b in the longitudinal direction of the blade support member 2 to one end thereof, a lead wire 10 having plugs 11 connected to both ends by clips 12 (see FIG. 2) attached to the peripheral surface thereof. Are wired.

As shown in FIG. 5, a U-shaped engagement groove 17 for connecting the blade support member 2 is formed in the tip 3b of the wiper arm 3, and the tip has a
Power supply-side lead wire 1 wired along wiper arm 3
A mounting hole 17a is formed for inserting the plug seat 15 connected to the front end of Oa from the front. The plug seat 15 as one side of the connector is provided with the center conductor 1 insulated from each other.
5b and a cylindrical portion 15c surrounding the periphery thereof, and a claw 15a which is engaged with a peripheral edge of the mounting hole 17a protrudes from a peripheral surface thereof. Correspondingly, the plug 11 as the other side of the connector has a central hole 11b in which the central conductor 15b is engaged and a cylindrical portion 11c that contacts the inner peripheral surface of the cylindrical portion 15c. A ring-shaped engagement groove 11a is formed around the cylindrical portion 15c.

The intermediate portion 2b of the blade supporting member 2 is shown in FIG.
And as shown in FIG. 5, it is comprised as the side surface 28 of the both sides which oppose at intervals which accommodate the clip 20 at intervals.
A rivet 29 is fitted into the mounting hole 28a, and the mounting hole 23 formed on the side surface of the clip 20 is swingably engaged. The clip 20 has a distal end portion 21 formed in a corresponding outer peripheral shape so as to be detachably engaged with the engaging groove 17, and projects slightly upward so as to secure this engaged state, and has a space 20 a. Forming both sides 2
2 is provided. Further, an intermediate wall 24 having an engaging groove 24a for engaging the engaging groove 11a of the plug 11 with the space portion 20a from below is formed between the side surfaces.

As shown in FIG. 3, the end of the blade 1 on the power supply side of the heater 7 is cut out in a U-shape leaving an end 1a, and a plug seat 15 connected to the heater 7 is provided with elasticity. A notch portion 1b to be held is formed. As a result, one plug 11 of the lead wire 10 is held by the end portion 1a in a state of being engaged with the plug seat 15, so that the appearance is not impaired, and the lead wire 10 is not separated by vibration or the like. . Note that the connector seat 15 and the connector 11 on the heater 7 side may have a different external structure from that for the intermediate portion 2b by eliminating the claw 15a and the engagement groove 11a.

When the clip 20 attached to the intermediate portion 2b of the blade support member 2 is engaged with the engagement groove 17 of the wiper arm 3 from the base end side by the wiper with heater configured as described above, the blade support member 2 Is connected to the wiper arm 3, and the plug 11 automatically engages with the plug seat 15 in the clip 20. Connector 11 on the other side
Is engaged with the plug seat 15 of the heater 7. Thereby, the heater 7 is connected to the two-pole lead wires 10a,
Powered through 0. When the blade 1 is replaced, it is possible to completely separate the wiring portion by removing the plug 1 from the claw 2a and removing the plug 11 from the plug seat 15 thereof. When the clip 20 is removed from the wiper arm 3 when replacing the blade supporting member 2, the plug 1
1 automatically leaves the plug seat 15 except for the lead wire 10a. At this time, the lead wire 10 can also be detached from the clip 12 and separated independently.

[0012]

According to the first aspect of the present invention, the blade containing the heater can be replaced separately from the wiring. At the time of replacement or attachment of the blade support member, attachment / detachment of the lead wire on the wiper arm side and the lead wire on the blade support member side are also performed automatically. The lead wire wired to the blade support member can be separated independently. According to the second aspect of the present invention, the periphery of the plug seat provided at the end of the blade can be concealed by the blade together with the plug, and it is also useful to prevent detachment due to vibration or the like.
