Abstract

A switch unit is provided, which includes: an operative body being swingingly operably provided; a pair of first switch portions being abuttable on respective end portions of the operative body when the operative body is swingingly operated so as to output signals to raise and lower, respectively, a window glass; a pair of second switch portions arranged apart from a line connecting the pair of first switch portions and nearer a longitudinal middle portion of the operative body than the first switch portions and being abuttable on the operative body when the operative body is swingingly operated so as to output signals to raise and lower, respectively, the window glass; and a pair of supporting portions arranged opposite to the pair of second switch portions with respect to the line, wherein the supporting portions abut on respective portions of the operative body when the first switch portions abut on the respective end portions of the operative body.

Claims

1. A switch unit, comprising:

an operative body being swingingly operably provided;

a pair of first switch portions being abuttable on respective end portions of the operative body when the operative body is swingingly operated so as to output signals to raise and lower, respectively, a window glass;

a pair of second switch portions arranged apart from a line connecting the pair of first switch portions and nearer a longitudinal middle portion of the operative body than the first switch portions and being abuttable on the operative body when the operative body is swingingly operated so as to output signals to raise and lower, respectively, the window glass; and

a pair of supporting portions arranged opposite to the pair of second switch portions with respect to the line,

wherein the supporting portions abut on respective portions of the operative body when the first switch portions abut on the respective end portions of the operative body.

2. The switch unit as set forth in claim 1, wherein

the supporting portions are formed in a same shape as at least either of the first and second switch portions.

3. The switch unit as set forth in claim 2, further comprising

a base equipped with the pair of first switch portions, the pair of second switch portions, and the pair of supporting portions,

the base including a plate member having:

a pair of projections projecting toward the operative body and forming outlines of the respective first switch portions;

a pair of second projections being in a same shape as the projections, projecting toward the operative body, and forming outlines of the respective second switch portions; and

a pair of supporting projections being in a same shape as the projections, projecting toward the operative body, and forming outlines of the respective supporting portions.

4. The switch unit as set forth in claim 3, wherein

the pair of supporting portions are arranged symmetrically with the second switch portions with respect to the line.

5. The switch unit as set forth in claim 2, wherein

the pair of supporting portions are arranged symmetrically with the second switch portions with respect to the line.

6. The switch unit as set forth in claim 1, wherein

the pair of supporting portions are arranged symmetrically with the second switch portions with respect to the line.

7. A switch unit, comprising:

an operative body being swingingly operably provided;

a pair of first switch portions being abuttable on respective end portions of the operative body when the operative body is swingingly operated so as to output signals to raise and lower, respectively, a window glass; and

a plurality of supporting portions arranged on both sides of a line connecting the pair of first switch portions and nearer a longitudinal middle portion of the operative body than the first switch portions while putting the first switch portions therebetween,

wherein the supporting portions abut on respective portions of the operative body when the first switch portions abut on the respective end portions of the operative body.

8. The switch unit as set forth in claim 7, wherein

the plurality of supporting portions are formed in a same shape as the first switch portions.

9. The switch unit as set forth in claim 8, further comprising

a base equipped with the pair of first switch portions and the plurality of supporting portions,

the base including a plate member having:

a pair of projections projecting toward the operative body and forming outlines of the respective first switch portions; and

a plurality of supporting projections being in a same shape as the projections, projecting toward the operative body, and forming outlines of the respective supporting portions.

10. The switch unit as set forth in claim 9, wherein

the plurality of supporting portions are arranged symmetrically with respect to the line.

11. The switch unit as set forth in claim 8, wherein

the plurality of supporting portions are arranged symmetrically with respect to the line.

12. The switch unit as set forth in claim 7, wherein

the plurality of supporting portions are arranged symmetrically with respect to the line.
