The handle mechanism 160 is fixed to the exterior tank 100 with the handle portion 161 protruding from the exterior tank 100 to the outside.

  The handle portion 161 is a member that is formed integrally with the shaft portion 162 and is rotatable about the shaft portion 162. The handle portion 161 is rotated in the direction corresponding to the amount of washing water discharged (large washing and small washing) by the toilet user. It is rotated. A cross-shaped convex portion (not shown) is formed at the tip of the shaft portion 162.

  The motor 163 rotates the shaft portion 162 according to various modes, and controls the opening / closing speed and timing of the valve body 142 and the drainage amount adjustment valve 143 of the drainage valve device 140.

  2A and 2B show a universal joint 170 of a tank apparatus according to an embodiment of the present invention, where FIG. 2A is a perspective view, FIG. 2B is a front view, and FIG. 2C is a view showing an end face of a fitting member 440. As shown in the figure, the universal joint 170 has a length sufficient to connect the spindle mechanism 180 and the handle mechanism 160 and is connected to one end of the joint portion 441 and a joint portion 441 capable of transmitting a rotational force. And the rod member 442 connected to the other end of the joint portion 441.

  Both ends of the joint portion 441 are respectively formed in bearing holes 441c and 441d concentrically formed at both ends of a pair of yokes 441a and 441b formed in a bifurcated shape. It is supported and configured to be rotatable. When a rotational force is applied to the fitting member 440, the joint member 441 and the rod member 442 rotate together. Further, since the joint portion 441 is interposed, the fitting member 440 and the rod member 442 can be positioned on different axes.

  The fitting member 440 is made of a cylindrical member having a cross-shaped recess 440a formed on the end surface. The fitting member 440 is connected to the shaft portion 162 by fitting the concave portion 440 a and a cross-shaped protrusion formed at the tip of the shaft portion 162 of the handle mechanism 160. For this reason, the rotational force transmitted to the shaft portion 162 is transmitted to the universal joint 170.

  The rod member 442 is formed of a long member having a cross-shaped cross section. A return portion 442a that protrudes outward is formed at the end of the rod member 442 opposite to the joint portion 441 connected thereto. In addition, a slit 442b extending in the axial direction is formed at the end, and the tip can be reduced in diameter by applying a force from the outside. A cross-shaped hole is formed inside the shaft member 410 of the spindle mechanism 180.

  The joint portion 441 has a length sufficient to connect the handle mechanism 160 and the spindle mechanism 180. For this reason, even when a manufacturing error occurs in the exterior tank 100 and an error occurs in the position and orientation of the handle mechanism 160 with respect to the spindle mechanism 180, the error is absorbed by the universal joint 170, and the handle mechanism 160. And the spindle mechanism 180 can be connected so as to be able to transmit a rotational force.

  3 to 5 show a spindle mechanism 180 of a tank apparatus according to an embodiment of the present invention, FIG. 3 is a perspective view, and FIG. 4 is an exploded perspective view. 5A is a front view, FIG. 5B is a side view, FIG. 5C is a top view, and FIG. 5D is a partial cross-sectional view of CC in FIG. As shown in FIGS. 3 to 5, the spindle mechanism 180 is spanned between the upper edges of the front surface and the rear surface of the interior tank 110, and has a guide member having a substantially circular cross-sectional through hole 400 a penetrating in the lateral direction. 400, an annular member 420 having an annular ring part 422, a shaft member 410 provided so as to pass through the through hole 400a of the guide member 400 and the annular part 422 of the annular member 420, and a cylindrical part 411. And a stopper 430 that prevents the annular portion 422 from detaching from the cylindrical portion 411 and prevents the cylindrical portion 411 from detaching from the guide member 400.

  The guide member 400 has a clip portion 401 that can hold a plate material between both ends thereof, and is fixed to the interior tank 110 by sandwiching the upper edges of the front surface and the back surface of the interior tank 110 by the clip portion 401. Has been. Further, a through hole 400 a penetrating in the lateral direction is formed in the center of the guide member 400.

  The shaft member 410 has a cylindrical tubular portion 411 with one edge portion 412 having an enlarged diameter, an arm portion 413 extending from the edge portion 412 toward the outer periphery, and an attachment that is rotatably attached to the tip of the arm portion 413. Part 414. The diameter of the cylindrical portion 411 is substantially equal to the through hole 400a of the guide member 400, and is inserted into the through hole 400a of the guide member 400 without a gap. As a result, the shaft member 410 is rotatably supported by the guide member 400. The upper end of the first ball chain 151 whose lower end is connected to the valve body 142 of the drain valve device 140 is connected to the mounting portion 414. Since the load of the valve body 142 acts on the shaft member 410 via the first ball chain 151 in a state in which no rotational force is acting, the arm member 413 takes a posture that extends downward.

  Further, a convex portion 415 is formed on the surface of the end portion of the tubular portion 411 on the annular member 420 side. That is, as shown in FIG. 5D, the convex portion 415 is positioned below the tubular portion 411 when the shaft member 410 is in a posture such that the arm portion 413 extends downward.

  A cross-shaped hole 416 into which the rod member 442 of the universal joint 170 can be inserted is formed in the cylindrical portion 411. By inserting the rod member 442 of the universal joint 170 into the hole 416, the universal joint 170 and the shaft member 410 are connected so as to be able to transmit a rotational force. The rod member 442 is slidable with respect to the shaft member 410 in the longitudinal axis direction.

  The annular member 420 includes an annular ring part 422 and an arm part 421 extending from the annular part 422 toward the outer periphery. The inner diameter of the annular part 422 is substantially equal to the cylindrical body 141 of the shaft member 410, and the annular member 420 is inserted through the cylindrical part 411 by inserting the cylindrical part 411 of the shaft member 410 into the annular part 442. The guide member 400 is rotatably supported.

  The upper end of the second ball chain 152 whose lower end is connected to the drainage amount adjustment valve 143 is connected to the tip of the arm part 421. In the state where the rotational force is not acting, the annular member 420 takes a posture such that the arm portion 421 extends downward because the load of the drainage amount adjustment valve 143 acts via the second ball chain 152.

  Further, an engaging portion 423 is formed on a surface of the annular portion 422 on the guide member 400 side so as to be along a part of the inner peripheral edge. In a state where the arm portions 413 and 421 of the shaft member 410 and the annular member 420 extend downward, the side surface of the convex portion 415 formed on the cylindrical portion 411 of the shaft member 410 and the end surface of the engaging portion 423 are in contact with each other. It touches.

  A direction in which the convex portion 415 of the cylindrical portion 411 and the end surface of the engaging portion 423 of the annular member 420 are separated from the handle mechanism 160 via the universal joint 170 to the shaft member 410 (A direction in FIG. 5D): When the rotation in the first rotation direction is applied, the annular member 420 is maintained in a posture in which the arm portion 421 extends downward, and only the shaft member 410 rotates in the first rotation direction. . Thereby, the arm part 413 of the shaft member 410 pulls up the first ball chain 151. Thereby, the valve body 142 is pulled up, the opening 111a is opened, and the washing water is supplied to the toilet body in the large washing mode.

  On the contrary, in the direction from the handle mechanism 160 to the shaft member 410 via the universal joint 170, the convex portion 415 of the cylindrical portion 411 faces the engaging portion 423 of the annular member 420 (in FIG. 5D). When rotation in the B direction (hereinafter referred to as the second rotation direction) is applied, the convex portion of the shaft member 410 engages with the engaging portion 423 of the annular member 420, so that the annular member 420 together with the shaft member 410 It rotates in the second rotation direction. Thereby, the arm portions 413 and 421 of the shaft member 410 and the annular member 420 pull up the first and second ball chains 151 and 152. Accordingly, the valve body 142 is pulled up to open the opening 111a, and the drainage amount adjustment valve 143 closes the opening 141a of the cylindrical body 141, so that the washing water is supplied to the toilet body in the small washing mode.

  In this embodiment, since the spindle mechanism 180 and the drain valve device 140 are attached to the interior tank 110 as described above, the distance between them does not change. For this reason, in the manufacturing process, the lengths of the first and second ball chains 151 and 152 are adjusted in advance so that there is no slack, and each end of each ball chain 151 and 152 is drained. The valve device 140 and the spindle mechanism 180 are connected to the arm portions 413 and 421.

  The handle mechanism 160 and the universal joint 170 are attached on site. That is, first, the handle mechanism 160 of the operation mechanism 150 is inserted into the handle insertion hole of the exterior tank 100, and the handle mechanism 160 is fixed to the exterior tank 100 in a state where the handle portion 161 protrudes to the outside.

  Next, the cruciform protrusion formed at the tip of the shaft portion 162 of the handle mechanism 160 is fitted into the cruciform recess 440 a formed on the end face of the fitting member 440 of the universal joint 170, and the handle mechanism 160. And universal joint 170 are connected. Further, the rod member 442 of the universal joint 170 is inserted into the hole 416 formed inside the cylindrical portion 411 of the spindle mechanism 180 in a state where the diameter is reduced by applying force from the outer periphery to the tip portion. Thereby, the rod member 442 is connected to the shaft member 410 of the spindle mechanism 180 so as to transmit a rotational force. The rod member 442 includes a return portion 442a at the tip, and therefore does not fall off the shaft member 410.

  According to the present embodiment, in the operation mechanism 150, the spindle mechanism 180 and the handle mechanism 160 are connected by the universal joint 170 capable of transmitting a rotational force. Even if a relative error with respect to the mechanism 180 occurs, the universal joint 170 can absorb this mounting error.

  The universal joint 170 is connected to the cylindrical portion 411 of the spindle mechanism 180 so that the rod member 442 can slide in the axial direction. For this reason, even when the distance between the spindle mechanism 180 and the handle mechanism 160 changes, the rod member 442 slides with respect to the cylindrical portion 411, so that the mounting error can be absorbed more reliably. These mechanisms can be connected.

  Further, as described above, in the present embodiment, since the manufacturing error is absorbed by the universal joint 170, it is possible to reliably transmit the rotation operation from the operation unit to the drain valve device.

  In the above embodiment, the drain valve device 140 including the cylinder 141 is used as the drain valve device. However, the present invention is not limited to this, and other drain valve devices such as a flapper valve are used. Even if it exists, this invention is applicable.
