  • Patent number: 10370878
    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.

  • Publication number: 20190232923
    Abstract: Provided is a washer nozzle that since a plurality of stepped portions (stepped wall portions) formed in a stepped shape in a flow direction of the cleaning liquid are provided in a flow path between an inflow hole and a discharge port in a main body portion, it is possible to spread the cleaning liquid in a width direction of the flow path by causing the cleaning liquid flowing from an upstream side to collide with stepped surfaces of the plurality of stepped portions one after another. Therefore, even when a flow rate of the cleaning liquid is small, without increasing a discharge capacity of a washer pump, it is possible to disperse the cleaning liquid fully in the width direction of the flow path, and it is possible to uniformly discharge the cleaning liquid to substantially the entire surface of an imaging lens.

  • Patent number: 10344813
    Abstract: A support portion (23) has three screw insertion portions (23d1, 23d2, and 23d3) which is fixed to a caliper, and arranged so as to surround an output shaft (39). Therefore, it is possible to firmly fix a case (21) to the caliper at these fixing locations. Additionally, since the fixing locations are determined so as to collectively define a “plane”, it is possible to effectively inhibit a sway of the case (21) with respect to the caliper. Furthermore, it is possible to inhibit a twist of the case (21), and it is possible to sufficiently support a vehicle requiring large torque such as a truck.
