Abstract: The disclosure provides a touch sensor unit. A conductive component is arranged between a pair of electrodes which are arranged inside an insulating tube, and the conductive component includes: a body section, which extends in a longitudinal direction of the insulating tube; and a convex section, which is arranged on an outer circumference of the body section, extends along the longitudinal direction of the body section, and sinks into the pair of electrodes. Short circuit or non-short circuit and so on of the electrodes can be detected by detecting the resistance value of the conductive component. Merely by inserting the conductive component into one end in the longitudinal direction of the electrodes, the pair of electrodes are electrically connected, and only the convex section sinks into the pair of electrodes, therefore the insertion load of the conductive component can be reduced, and the terminal treatment can be simplified.

Abstract: An object of the present invention is to enhance stiffness of a cable end without increasing the size of the cable end. A first retaining protrusion (35b) is provided on the tip side of a second roller pin (35) so as to protrude from the second roller pin (35) in a radially outward direction of the second roller pin (35), a cable end (40) is formed with an insertion hole (43) including an arc-shaped second inner wall (43b), the first retaining protrusion (35b) being allowed to pass through the insertion hole (43). A bush (50) is provided with: a notch (51a) which exposes the second inner wall (43b) to the outside, the first retaining protrusion (35b) being allowed to pass through the notch (51a); and a cylindrical main body (51) which covers a first inner wall (43a), the first retaining protrusion (35b) abutting on the main body (51) in a radial direction of the second roller pin (35).

Abstract: Since a shape of a stator 44 is made mirror symmetric with respect to a rotor 45 as a 4-pole/6-slot type, rotational deflection of the rotor 45 can be suppressed. As the minimum number of poles and the minimum number of slots, which can suppress the rotational deflection of the rotor 45, a frequency of magnetic noises approaches a frequency of mechanical noises. Thus, it is possible to integrate the whole noises generated by the DR-side wiper motor 21 into a low frequency range thereof, and to make the acoustic sensitivity (dB) of a vehicle interior smaller. Since the stator 44 is fixed inside a housing 40 and mounting legs fixed to a vehicle body fixed portion are provided in the housing 40, the stator 40, which is a source of the magnetic noises, can be fixed to a vehicle via only the housing 40. Therefore, a brushless wiper motor with quietness improved further can be designed.

Abstract: First and second bridging portions (63a and 63b) is disposed so as to form a shock absorbing space (63c) between the sensor accommodating portion (61) and the fixing portion (62), and elastically deformed by external force, and the paired bridging portions (the shock absorbing space (63c)) is caused to function as a shock absorbing portion (63). Furthermore, the sensor accommodating portion (61) is thinner than each of the bridging portions (63a and 63b), after the sensor accommodating portion (61) is elastically deformed and a contact of a blockage is detected, the first and second bridging portions (63a and 63b) can be elastically deformed to absorb a shock. Therefore, it is possible to significantly reduce a load on the blockage in comparison with the conventional technique. Since the drive unit is reversely driven after shock absorption, it is possible to reduce the load on the drive unit and so forth, and to inhibit the occurrence of inconvenience such as burning.
