Embodiment Construction
[0033] The following will be based on Figure 1 to Figure 15 An embodiment in which the present invention is embodied in a motor for a wiper device of a vehicle wiper device will be described.
[0034] like figure 1 As shown, a motor for a wiper device (hereinafter simply referred to as a motor) 1 has a motor main body 2 and a gear unit 3 . The motor main body 2 has a substantially bottomed cylindrical yoke housing (yoke housing) 4, a plurality of magnets 5 fixed to the inner peripheral surface of the yoke housing 4, and a rotor accommodated in the same yoke housing 4 ( Spinner) 6. The rotor 6 has a rotating shaft 7 , and a worm 8 is formed on the head end side of the rotating shaft 7 protruding from the opening of the yoke case 4 .
[0035] The gear part 3 has a case 11 as a gear case (refer to figure 2 ), worm gear 12 (refer to figure 1 ), the box cover 13 as the cover (refer to Figure 4 ), component board 14 (refer to Image 6 ), rotating body 15 (refer to image ...

Abstract
To provide a structure of a casing, which structure can improve the waterproofness while securing the reliability of electric connection of a ground terminal. The structure of the casing is configured such that the housing side edge portion of a housing and the cover side edge portion 13a of a housing cover 13 are overlapped together and are connected and fixed with each other via their fixing holes 13g and screws to be inserted into the fixing holes, and electric components including a first fixed contact point terminal 23 are received inside the housing and the housing cover. In addition, the co-fastening connecting portions 23h of the first fixed contact point terminal 23 are gripped by means of the housing side edge portion and the cover side edge portion 13a by arranging them so as to surround the screws. A housing side circuitous portion detouring the outside of the fixing holes is formed on the housing side edge portion, and a cover side circuitous portion 13i detouring the outside of the fixing holes 13g is formed on the cover side edge portion 13a. A sealing member 16 to be located between the housing side edge portion and the cover side edge portion 13a has a seal side circuitous portion 16a passing the housing side circuitous portion and the cover side circuitous portion 13i.
Description
technical field [0001] The present invention relates to a case structure for accommodating electrical components including ground terminals and a motor using the case structure. Background technique [0002] Conventionally, a motor or the like used in a vehicle wiper device or the like has a motor main body and a gear portion. In the gear unit, electrical components such as gears and various terminals are housed inside the case and the cover that closes the opening of the case. In addition, as such a motor (casing structure), there is a design in which a part (common connection portion) of a ground terminal serving as an electrical component is sandwiched between both edge portions of the case body and the cover body (overlapped parts). In the connection part of the fitting surface), it is electrically connected with a box or a cover made of a conductive material (for example, JP-P-11-150910). Specifically, the box is fastened by a bolt that passes through a hole formed on...
