The first wall portion 413a and the second wall portion 413b are arranged so as to face each other and form a pair of facing wall portions facing each other in the outer wall of the tank body 41. The first wall portion 413a is arranged on the wash water spouting portion 511a and the overflow pipe 15 side of the main flow passage portion 511, which will be described later, in the left-right direction of the tank body 41, relative to the second wall portion 413b and the third wall portion 413c. (See Figure 3B). As shown in FIG. 5, the first wall portion 413a and the second wall portion 413b are formed to be slightly inclined so as to gradually separate from the upper side to the lower side.

As shown in FIGS. 3A to 5, the first wall portion 413a and the second wall portion 413b configure a motor housing portion 414 as an electronic component housing portion that houses the motor 7a (electronic component). The first wall portion 413a and the second wall portion 413b are a part of the peripheral wall 412 that is the outer wall of the tank body 41. The motor 7a of the cleaning drive unit 7 is housed in the motor housing portion 414. The motor housing portion 414 is provided with an opening 410 below, and the motor housing portion 414 is formed outside the outer wall of the tank body 41 so as to vertically penetrate the tank body 41. The motor 7a is accommodated in the motor accommodating portion 414 at the upper end of the tank main body 41 while being attached to the first lid portion 43 of the tank lid portion 42 described later.

The upper end portions of the first wall portion 413a, the second wall portion 413b, and the third wall portion 413c are arranged at a position lower than the upper end portion of the peripheral wall 412 of the tank body 41 that does not form the motor housing portion 414. .. Accordingly, when the water level of the wash water is higher than the upper end portions of the first wall portion 413a, the second wall portion 413b, and the third wall portion 413c that configure the motor housing portion 414, the wash water configures the motor housing portion 414. The first wall portion 413a, the second wall portion 413b, and the third wall portion 413c overflow from the upper ends thereof. In the present embodiment, the base plate 3 is arranged below the tank body 41. Therefore, the wash water overflowing from the upper ends of the outer walls (the first wall portion 413a, the second wall portion 413b, and the third wall portion 413c) forming the motor housing portion 414 flows into the base plate 3. In this way, the wash water that has reached the upper ends of the outer walls (the first wall portion 413a, the second wall portion 413b, and the third wall portion 413c) forming the motor housing portion 414 overflows to the outside of the tank body 41.

Therefore, the upper end portions of the first wall portion 413a, the second wall portion 413b, and the third wall portion 413c that form the motor housing portion 414 are located closer to the upper end portions of the outer wall of the tank body 41 that does not form the motor housing portion 414. By arranging in the lower position, for example, the flapper valve (not shown) or the drive mechanism for driving the flapper valve (not shown) is broken, and the drainage port (not shown) opened and closed by the flapper valve (not shown). If the washing water remains closed, it is possible to provide a function of overflowing the washing water when the washing water cannot be completely discharged from the overflow pipe 15.

Since the motor 7a of this embodiment is an electronic component, it must be prevented from submerging in water. However, the motor 7a is provided with a structure and treatment that has water resistance so that it will not be destroyed when it is splashed with water. Therefore, since the motor housing portion 414 has the overflow function, even if the motor 7a is splashed with water, the motor 7a is not broken and the operation of the motor 7a is not affected.

The motor housing portion 414 has a bridge portion 415, as shown in FIGS. 3A and 3B. The bridge portion 415 has a bridge portion main body 415b and a bridge upper surface portion 415a.
The bridge portion main body 415b connects the first wall portion 413a and the second wall portion 413b (a pair of opposing wall portions) in the left-right direction of the toilet flush tank 4 on the rear side of the tank main body 41 above the tank recess 413. It is formed. The bridge main body 415b is formed in a rectangular plate shape extending in the vertical direction and the horizontal direction of the tank main body 41 at the upper part of the tank recess 413, and extends a predetermined length downward from the upper end of the tank recess 413. The bridge upper surface portion 415a is formed with a width in the front-rear direction at the upper end portion of the bridge portion main body 415b and constitutes a seat surface on which the tank lid portion 42 is arranged. The motor 7a is attached to the first lid 43, and the front side of the motor 7a is supported by the tank body 41 and the rear side of the motor 7a is supported by the bridge portion 415.

As shown in FIGS. 3A and 3B, the first wall portion 413a has a rib portion 416 as a guide portion on the outer surface thereof. Here, the first wall portion 413a is closer to the motor housing portion 414 in the left-right direction than the second wall portion 413b and the third wall portion 413c are the wash water spouting portion 511a and the overflow pipe 15 side of the main flow passage portion 511 described later. (See FIG. 3B). Therefore, the rib portion 416 includes the flush water spouting portion 511a and the overflow pipe 15 of the main flow passage portion 511, which will be described later, among the first wall portion 413a, the second wall portion 413b, and the third wall portion 413c that form the motor housing portion 414. Is disposed on the first wall portion 413a on the side where the wash water vigorously flows. Accordingly, the rib portion 416 causes the wash water overflowing from the first wall portion 413a, the second wall portion 413b, and the third wall portion 413c to reach the first wall portion 413a on the side where the wash water vigorously flows. It is possible to suppress splashing of the droplets.

The rib portion 416 is formed on the outer surface of the first wall portion 413a, and is formed in a plate shape extending downward from the lower end portion of the bridge portion 415. The rib portion 416 linearly extends in the vertical direction on the outer surface of the first wall portion 413a. The rib portion 416 includes an upper rib 416a, an intermediate inclined rib 416b, and a lower rib 416c.

The upper rib 416a protrudes from the outer surface of the first wall portion 413a by a certain amount (height) and extends downward on the upper side of the first wall portion 413a. The amount of protrusion of the upper rib 416a is such that, on the upper side of the first wall portion 413a, a large amount of wash water overflows from the upper end portion of the first wall portion 413a, so that the overflow wash water can be dammed up. Is preferably Further, it is preferable that the length of the upper rib 416a in the up-down direction is a length that can prevent the wash water overflowing from the first wall portion 413a from being transmitted and splashing the wash water to the outside of the tank body 41. By providing the upper rib 416a, the wash water overflowing from the first wall portion 413a is guided downward through the upper rib 416a.

The inclined rib 416b extends downward from the lower end of the upper rib 416a. It is arranged between the upper rib 416a and the lower rib 416c. The inclined ribs 416b extend so as to be inclined so that the protruding amount from the outer surface of the first wall portion 413a becomes lower as it goes downward from the lower end portion of the upper rib 416a. The inclined rib 416b transfers the cleaning water guided by the upper rib 416a to the inclined portion of the inclined rib 416b and guides it to the lower rib 416c. By disposing the inclined rib 416b between the upper rib 416a and the lower rib 416c, the washing water guided by the upper rib 416a is prevented from being scattered to the outside of the tank main body 41 in a downward direction. It can be transmitted to the side rib 416c.

The lower rib 416c extends downward from the lower end of the inclined rib 416b. The lower rib 416c extends downward at a position lower than the upper rib 416a on the outer surface of the first wall portion 413a. The lower rib 416c projects from the outer surface of the first wall portion 413a to a certain height with a lower projecting amount than the upper rib 416a. The lower end 416d of the lower rib 416c is arranged below the upper end of the side wall of the base plate 3 in the horizontal direction.

The lower rib 416c can guide the wash water to the base plate 3 by transmitting the wash water, which is suppressed from being scattered in the upper rib 416a, downward. Even if the protruding amount of the lower rib 416c is smaller than the protruding amount of the upper rib 416a, the momentum of the washing water overflowing from the upper end portion of the first wall portion 413a is suppressed in the upper rib 416a. The lower rib 416c can guide the cleaning water downward.
Since the lower end portion 416d of the lower rib 416c is arranged below the upper end portion of the side wall of the base plate 3 in the horizontal direction, the cleaning water that has been transmitted to the lower end portion 416d of the lower rib 416c is stored in the side wall of the base plate 3. As a result, scattering outside the base plate 3 is suppressed.

Further, in a factory or the like, a plurality of tank bodies 41 may be stacked and stored. Here, the amount of protrusion of the lower rib 416c is formed to be smaller than the amount of protrusion of the upper rib 416a, and when the tank main body 41 is stacked, the amount of protrusion from the outer surface of the first wall portion 413a is more than one. A protrusion amount that does not hinder the stacking of the tank bodies 41 is set. Thereby, the plurality of tank bodies 41 can be easily stacked.

As shown in FIG. 5, in the present embodiment, when the motor 7a is accommodated in the motor accommodating portion 414, the lower portion of the motor 7a is outside the tank body 41, and the cleaning water stored in the tank body 41 is outside the tank body 41. It is located below the water surface. The position of the lower portion of the motor 7a may be outside the tank body 41 and above the surface of the wash water stored in the tank body 41.

As shown in FIG. 2, the base plate 3 is arranged below the opening 410 formed below the motor housing 414 (tank recess 413 of the tank body 41). The guide wall 31 is formed on the base plate 3 as described above.
