Therefore, the toilet lid protrusion 213d and the locking recess 312a can constitute toilet lid opening maintaining means for maintaining the opened state (standing state) of the toilet lid 21.

  A cleaning nozzle 261 (cleaning unit) that ejects warm water, which is cleaning water, is incorporated in a local part of the human body near the center of the main body 222. The cleaning nozzle 261 has an expandable / contractible nozzle 262 that can be expanded and contracted forward. At the time of local cleaning, the expansion / contraction nozzle 262 protrudes from the nozzle opening 2p due to water pressure or the like and extends in the direction of the arrow K1 toward the toilet 1. When it is not during local cleaning, the expansion / contraction nozzle 262 is retracted in the direction of the arrow K2 by a return spring (not shown) and concealed in the main body 222.

  A shutter 232a that forms a part of the lower member 222L of the toilet seat 22 is configured to open and close about the rotary hinge 233a. The shutter 232a is closed when the integral toilet seat 22 is opened (when standing, see FIG. 11), and is opened when the integral toilet seat 22 is closed (see FIG. 10). The opening / closing operation of the shutter 232a is performed by gravity acting on the shutter 232a. The telescopic nozzle 262 can enter and exit in the directions of the arrows K1 and K2 by rotating and opening the shutter 232a. The shutter 232a is held by a member 226c that is directly below the cleaning nozzle 261. A shroud 236 that functions as a water shielding wall that temporarily holds drain water from the cleaning nozzle 261 or drain water from the hot water tank is provided behind the shutter 232a. As a result, a drain water pool 235 (water holding portion) is formed. As shown in FIG. 10, when the integrated toilet seat 22 is closed, the drain water reservoir 235 is positioned below the washing nozzle 261 so that the drain water falling from the washing nozzle 261 can be received. The shutter 232a is also configured to receive the drain water falling from the cleaning nozzle 261.

  As shown in FIG. 11, when the integrally constructed toilet seat 22 is turned upward and stands up (in the direction of arrow Y1), the discharge port 235f of the drain water pool 235 is closed by the shutter 232a. This prevents the drain water temporarily held in the drain water pool 235 from scattering. That is, when the toilet seat 22 is rotated upward and is in an upright state, the drain water is concentrated in the drain water pool 235 surrounded by the enclosure plate 236 and the direct member 226c, and becomes the stored water 237. The scattering of water in the integrally constructed toilet seat 22 is suppressed. In order to receive water falling from the cleaning nozzle 261, the end 226 e of the shroud 236 is preferably close to the cleaning nozzle 261. As shown in FIG. 10, when the integrally constructed toilet seat 22 is rotated downward (in the direction of arrow Y2) and closed, the shutter 232a is opened by gravity, and the drain puddle 235 lies in a state close to horizontal. The drain water in the pool 235 is naturally discharged into the toilet 1 by gravity. Accordingly, every time the integral toilet seat 22 swings downward and is closed, the drain water stored in the drain water reservoir 235 is naturally discharged into the toilet 1 by gravity.

It is guided by 241x so as to be able to move up and down along the height direction. Therefore, the integrated toilet seat 22 can function as a guide element that guides the toilet seat 22 along the direction perpendicular to the opening surface 1k of the toilet 1. The holding hole 241x related to the other fitting portion 240b is a first hole 241x1 for fitting the bearing portion 243b, a second hole 241x2 for fitting the flange portion 244b, and a third hole for fitting the guide rod portion 245b. 241 × 3.

  As shown in FIG. 14, a fixing portion 31 for attaching the integrally constructed toilet seat 22 is detachably fixed to the attaching portion 11 of the toilet 1. The fixing portion 31 includes a fixing base 311 fixed to the mounting portion 11 of the toilet 1 by toilet fixing bolts 315a and 315b as fastening elements, and a H-shaped corner with a cross section protruding upward on both sides of the fixing base 311. It has the insertion parts 311a and 311b which make a cylindrical shape. The inserted portions 311a and 311b have a to-be-inserted space 311x in the shape of a rectangular tube that opens upward. The fixed base 311 is formed with a pair of bolt grooves 314 a and 314 b extending in the front-rear direction of the toilet seat portion 211. As shown in FIG. 14, with the heads of the toilet bowl fixing bolts 315a and 315b fitted into the bolt grooves 314a and 314b, the fixing section 31 is detachably fixed to the mounting section 11 of the toilet bowl 1 through the rubber washer 316a. ing.

  Now, a description will be given of the case where the integrally constructed toilet seat 22 is detachably installed on the toilet bowl 1. First, as shown in FIG. 14, the integrally constructed toilet seat 22 is disposed above the fixed portion 31. Thereafter, the integrally constructed toilet seat 22 is lowered in the direction of the arrow DA. As a result, the rectangular tube-shaped insertion portion 241 c of the fitting portion 240 a of the toilet seat 22 is detachably inserted into the rectangular tube-shaped insertion portion 311 a of the fixing portion 31. Similarly, the rectangular tube-shaped insertion portion 241d of the fitting portion 240b of the integrally constructed toilet seat 22 is detachably inserted into the rectangular tube-shaped inserted portion 311b of the fixing portion 31. Since the rectangular cylindrical shapes are inserted, positioning accuracy for positioning the integrally constructed toilet seat 22 is ensured. Accordingly, the toilet seat 22 is detachably held in the toilet 1 in a state where the toilet seat 22 is positioned. Therefore, the fitting portions 240 a and 240 b can function as positioning elements for positioning the integrated toilet seat 22 when the integrated toilet seat 22 is installed on the toilet 1. When an unlocking selection mechanism for detachably locking the toilet seat 22 to the fixed portion 31 is provided, it is preferable that the unlocking selection mechanism is in a locking form.

  According to the present embodiment, as described above, the output shaft 252, the support shaft 259, and the like can be held in a float state at predetermined height positions by the guide rod portions 245a and 245b and the flange portions 244a and 244b. As shown in FIG. 13, shaft clearances 247a and 247b are provided between the upper surfaces of the output shaft 252 and the support shaft 259 and the upper ends of the fixed holding portions 241a and 241b. A gap 244r is formed above the flange portions 244a and 244b. Float displacement in a direction perpendicular to the opening surface 1k of the toilet 1 of the toilet shaft 1 of the output shaft 252 and the support shaft 259 that function as a pivot shaft that pivotally supports the integral toilet seat 22 by the shaft clearances 247a and 247b and the gap 244r. Is secured. Therefore, the output shaft 252 and the support shaft 259 can be displaced along a direction perpendicular to the opening surface 1 k of the toilet 1.

  When cleaning or the like is performed, the toilet seat 22 is lifted upward (in the direction of the arrow DB shown in FIG. 14) with the toilet fixing bolts 315a and 315b being fastened to the toilet 1. Thereby, the rectangular tube-shaped insertion portion 241 c of the fitting portion 240 a of the toilet seat 22 is detached from the rectangular tube-shaped insertion portion 311 a of the fixing portion 31. Similarly, the rectangular tube-shaped insertion portion 241 d of the fitting portion 240 b of the toilet seat 22 is detached from the rectangular tube-shaped insertion portion 311 b of the fixing portion 31. Thereby, the integrally constructed toilet seat 22 can be lifted and removed from the toilet 1 easily. In this case, when an unlocking selection mechanism for detachably locking the integrated toilet seat 22 to the fixing portion 31 is provided, the integrated toilet seat 22 is lifted with the unlocking selection mechanism released. Is preferred.

  Even when the integrated toilet seat 22 is not removed from the toilet bowl 1, if the integrated toilet seat 22 is lifted to a certain height in the direction of the arrow DB, the cleaning toilet 22 is disposed between the upper surface of the fixed portion 31 and the lower surface of the integrated toilet seat 22. A gap can be formed. Similarly, a cleaning gap can be formed between the upper surface of the toilet 1 and the lower surface of the integrally constructed toilet seat 22. The user can perform cleaning and the like through these gaps. Note that the toilet fixing bolts 315a and 315b can be removed from the toilet 1 as necessary.

  By the way, as described above, the toilet seat opening / closing drive device 251 (first drive device) is fixed in the integral toilet seat 22, and drives the integrated toilet seat 22 for rotational opening and closing. Is formed. As shown in FIG. 14, the toilet seat opening / closing drive device 251 is fixed to the inside of the integrated toilet seat 22 via a presser plate 253 with a fixing screw 254 x on a mounting base 228 provided on a lower member 221 </ b> L of the integrated toilet seat 22. . The output shaft 252 of the toilet seat 251 is prevented from rotating with respect to the integrated toilet seat 22 so as to be able to rotate integrally with the integrated toilet seat 22. Specifically, as shown in FIG. 13, the output shaft 252 is formed with parallel chamfered D-cut portions 252d (two locations). The D cut portion 252d is fitted in the vertically long holding hole 241x of the fixed holding portion 241a and is prevented from rotating.

  Therefore, as can be understood from FIG. 13, when the toilet seat opening / closing drive device 251 is turned on, the output shaft 252 rotates about its axis. At this time, the output shaft 252 that is prevented from rotating is stationary at that position, that is, in a non-rotating state with respect to the toilet 1, and the toilet seat opening / closing drive device 251 rotates together with the integral toilet seat 22. Thus, when the integrally constructed toilet seat 22 is pivotally opened and closed, as shown in FIG. 13, the rear end portion 22r of the integrally constructed toilet seat 22 faces the space 22k below the rear end portion 22r. It rotates in the direction of arrow Y5 around the heart. The output shaft 252 and the support shaft 259 are disposed on the same axis, and the integrally constructed toilet seat 22 is opened and closed around the output shaft 252 and the support shaft 259. However, since the fitting portion 240b is not an output shaft, the support shaft 259 is rotatable with respect to the fixed holding portion 241b.

  According to the present embodiment, as shown in FIG. 15, the heat shield plate 227 is formed between the upper member 221 </ b> U constituting the toilet seat 221 and the upper member 222 </ b> U constituting the main body 222. As shown in FIG. 1, the heat shield 227 extends along the width direction of the toilet seat 221, and an electric toilet seat heater 2 h (see FIG. 1) is disposed on the upper member 221 </ b> U of the toilet seat 221. As shown in FIG. 10, the upper end portion 227u of the heat shield plate 227 is in close contact with the back surface side of the upper member 221U. Further, the lower end portion 227d of the heat shield plate 227 engages with the rear end upper surface portion 221m of the lower member 221L of the toilet seat portion 221. Note that the heat shield plate 227 may be formed with a minimum number of holes or gaps necessary for passing electrical wiring or the like as necessary.

  As described above, the integrated toilet seat 22 forms a casing in which the toilet seat portion 221 and the main body portion 222 are continuous, and the internal space of the integrated toilet seat 22 tends to be relatively large and continuous. For this reason, there is a tendency that the heat for the heated toilet seat of the toilet seat portion 221 moves to the main body portion 222 through the internal space, and there is a limit in reducing the power consumption of the toilet seat heater 2h. Furthermore, since a temperature rise in the main body 222 is also induced, there is room for improvement in order to increase the reliability of the functional components accommodated in the main body 222.

  In this regard, according to this embodiment, as shown in FIG. 10, a heat shield plate 227 as a heat shield element is provided in a partition shape between the toilet seat portion 221 and the main body portion 222 of the integrally constructed toilet seat 22. Yes. The heat shield 227 enhances the incompatibility between the internal space of the toilet seat 221 and the internal space of the main body 222. Specifically, the communication between the internal space of the toilet seat 221 and the internal space of the main body 222 is blocked. For this reason, when the toilet seat heater 2h of the toilet seat portion 221 is heated, the heat shield plate 227 suppresses the heat of the heated toilet seat portion 221 from being transmitted to the main body portion 222 through the internal space or the like. . Accordingly, the temperature rise in the main body 222 is suppressed, and various functional components (for example, electronic components and electric components such as the electric control board 294, the toilet lid opening / closing driving device 255, the toilet seat opening / closing driving device) accommodated in the main body 222 251, drying device 271, etc.) can contribute to improving the reliability, improving the durability, and extending the service life. Further, since the heat of the toilet seat 221 serving as a heating toilet seat is suppressed by the heat shield plate 227 from being transmitted to the main body 222, it is advantageous for securing the temperature of the toilet seat 221 and energy saving and power saving are achieved. Can also contribute to a reduction in the heating capacity of the toilet seat heater 2h. The heat shield plate 227 may be formed integrally with the integrally constructed toilet seat 22 or may be attached to the integrally constructed toilet seat 22 later.

  Further, as shown in FIG. 1, the heat shield plate 227 is provided between the toilet seat 221 and the main body 222 of the integrally constructed toilet seat 22 so as to substantially follow the contour of the user's hip. For this reason, when the user's bottom is seated on the toilet seat 221 of the toilet seat 22, the heat shield 227 is positioned near the bottom, and the vicinity of the bottom of the toilet seat 221 that is a heating toilet seat is located. It can contribute to keeping the temperature of the area high and is suitable for use in winter. Further, as shown in FIG. 10, since an air heat insulating layer 227 a as a heat shielding element is also formed between the toilet seat 221 and the main body 222, the heat of the toilet seat 221 is transmitted to the main body 222. This is further suppressed. The air heat insulating layer 227a is not only formed of air, but a gel-like substance having high heat shielding properties may be disposed on the air heat insulating layer 227a. Furthermore, according to the present embodiment, as shown in FIG. 10, the upper end portion 227u of the heat shield plate 227 is in close contact with the back side of the upper member 221U of the toilet seat 221. For this reason, the air blocking property between the internal space of the toilet seat 221 and the internal space of the main body 222 is enhanced. Therefore, the entry and exit of air between the internal space of the toilet seat portion 221 and the internal space of the main body portion 222 is suppressed. For this reason, the convection by the air heated by the toilet seat heater 2h for the heating toilet seat of the toilet seat part 221 is suppressed. Thereby, the heat transfer of the location where temperature is the highest inside the toilet seat part 221 and air convection is easy to occur can be prevented. Similarly, the lower end portion 227d of the heat shield plate 227 is also engaged with the rear end portion of the lower member 221L of the toilet seat portion 221 of the main body portion 222. Therefore, also in this sense, the internal space of the toilet seat portion 221 and the main body portion The barrier property of the internal space 222 is enhanced. Therefore, the entry and exit of air between the internal space of the toilet seat 221 and the internal space of the main body 222 is suppressed. Thereby, the heat of the toilet seat heater 2h can be efficiently used for heating the toilet seat portion 221, and the ability as a heating toilet seat can be maintained while energy saving of the toilet seat heater 2h is achieved.

  By the way, the toilet bowl 1 is made of earthenware produced industrially, and the mounting surface of the mounting portion 11 of the toilet bowl 1 may have distortion or the like in a strict sense. This is even more so when the toilet bowl 1 undergoes a sintering process. Accordingly, when the main body 222 of the toilet seat 22 is fixed to the mounting portion 11 of the toilet 1 in a rigid (high rigidity state), the support of the output shaft 252 and the support shaft 259 is also rigid (in a high rigidity state). easy. In this case, when the user is seated on the toilet seat part 221 of the integral toilet seat 22, when the weight of the user is loaded on the toilet seat part 221 of the integral toilet seat 22, such as distortion of the attachment surface of the attachment part 11 of the toilet 1. Due to the influence, the rubber legs 223 do not partially land on the toilet 1 and there is a possibility that unnecessary stress acts on the integrally constructed toilet seat 22.

  In this regard, according to this embodiment, in the state in which the toilet seat 22 is mounted on the toilet bowl 1, as described above, the bearing portion that is urged by the urging force of the elastic bodies 246a and 246b that function as the urging members. The output shaft 252 and the support shaft 259 (corresponding to the rotation shaft of the integral toilet seat 2) serving as a rotation shaft for rotating and opening and closing the integral toilet seat 22 by 243a and 243b are directions perpendicular to the opening surface 1k of the toilet 1 It is possible to displace along. In other words, the output shaft 252 and the support shaft 259 are floated, for example, about 0.1 to 7 millimeters, and can be displaced along a direction perpendicular to the opening surface 1 k of the toilet 1. As a result, the output shaft 252 and the support shaft 259 are set to be displaceable along a direction perpendicular to the opening surface 1k of the toilet 1 and the free displaceability of the output shaft 252 and the support shaft 259 as the rotation shaft is set. It is secured. Here, “the output shaft 252 and the support shaft 259 can be displaced along the direction perpendicular to the opening surface 1 k of the toilet 1” means that the output shaft 252 and the support shaft 259 are perpendicular to the opening surface 1 k of the toilet 1. It is meant to include a form that can be displaced and a form that can be displaced in a direction substantially perpendicular to the opening surface 1 k of the toilet 1.

According to the present embodiment, when the user is not seated on the integrated toilet seat 22, the bottom 223b of the integrated toilet seat 22 floats upward from the toilet 1 by an amount corresponding to Δt (see FIG. 12) . That is, the integrally constructed toilet seat 22 is held in the toilet 1 in a float state in which a minute amount can sink. When the user sits on the toilet seat portion 221 of the toilet seat 22, the output shaft 252 and the support shaft 259 are seated against the urging force of the elastic bodies 246 a and 246 b and are perpendicular to the opening surface 1 k of the toilet 1. Descent along the right direction. As a result, even if an unreasonable force acts on the output shaft 252 and the support shaft 259 of the integrally constructed toilet seat 22, it can be absorbed. Thereby, the rubber leg 223 on the back surface of the integrally constructed toilet seat 22 can reliably contact the toilet 1. For this reason, it is suppressed that stress, such as a big shear force, acts on the output shaft 252 and the support shaft 259 grade | etc.,. Furthermore, it is also possible to prevent an uneven load from being applied to the toilet seat opening / closing drive device 251.

  On the other hand, even when a convex portion is present on the mounting surface of the mounting portion 11 of the toilet 1 and the toilet seat portion 221 of the integrally constructed toilet seat 22 is to be lifted, the output shaft is floated in the vertical direction. Since 252 or the support shaft 259 can move upward, a large load is suppressed from being applied to the output shaft 252 or the support shaft 259 or the toilet seat opening / closing drive device 251 as described above. Note that the output shaft 252 or the support shaft 259 or the like can be used even when the integrated toilet seat 22 is suspended by its own weight without providing the elastic bodies 246a and 246b that exert the urging force to float the bearing portions 243a and 243b. Any device that forms a gap that can be moved up and down appropriately is acceptable.

  Further, according to this embodiment, when the cleaning function of the human body local cleaning device 2 is used, as shown in FIG. 10, the expansion / contraction nozzle 262 of the cleaning nozzle 261 extends in the direction of the arrow K1, and the cleaning water is supplied from the expansion / contraction nozzle 262. It is ejected toward the local part of the human body. When the cleaning is completed, the expansion / contraction nozzle 262 of the cleaning nozzle 261 is retracted in the arrow K2 direction by return means such as a return spring. During the cleaning, drain water may fall from the cleaning nozzle 261. Even in such a case, the drain water is concentrated in the drain water pool 235. When the integrated toilet seat 22 is closed, as shown in FIG. 10, the drain water in the drain water reservoir 235 passes through the first shutter 232a in the opened state and the second shutter 232b in the opened state. It is supposed to be discharged. When the integrated toilet seat 22 is closed, the first shutter 232a and the second shutter 232b are automatically opened by a moment action of a weight (not shown) or a gravitational action, and the drain water in the drain pool 235 is taken into the toilet 1 Can be discharged. When the integrally constructed toilet seat 22 is pivotally opened in the direction of the arrow Y1, as shown in FIG. 11, the first shutter 232a and the second shutter 232b are automatically closed by the moment action or gravity action of a weight (not shown). It is suppressed that the drain water of the water pool 235 scatters in the integral toilet seat 22.

  However, the drain water collected in the drain water reservoir 235 may remain completely drained due to surface tension and dirt adhesion. In such a case, even if the integrally constructed toilet seat 22 is erected in an open state, residual water is not scattered inside the enclosure plate 236. In particular, even if the unitary toilet seat 22 is erected in the maximum open state, residual water is prevented from splashing inside the enclosure plate 236. Therefore, the possibility of water adhering to functional parts such as electric parts and electronic parts inside the integrally constructed toilet seat 22 is suppressed. Therefore, it is possible to provide a highly reliable human body local cleaning device for functional parts such as electric parts and electronic parts.

  When the toilet lid 21 is pivoted and opened in the direction of arrow Y1, the toilet lid output shaft 256 of the toilet lid opening / closing drive device 255 is pivoted in the opening direction, and the toilet lid output shaft 256 is in a predetermined position. The lid opening / closing drive device 255 is stopped. At this time, as shown in FIG. 10, the locking recess 313 a formed on the back surface of the locking portion 312 of the fixing portion 31 and the toilet lid protrusion 213 d are detachably engaged, and both are coupled. Thereby, the standing state of the toilet lid 21 is maintained. The toilet lid opening / closing drive device 255 for opening / closing the toilet lid 21 and the toilet seat opening / closing drive device 251 for opening / closing the toilet seat 22 are both fixed inside the toilet seat 22.

  A description will be added to FIGS. FIG. 16 shows a state where the toilet lid 21 and the integrally constructed toilet seat 22 are both closed. Since the integrated toilet seat 22 is closed, the toilet lid opening / closing drive device 255 and the toilet seat opening / closing drive device 251 provided inside the integrated toilet seat 22 are both in the normal mounting position, and the toilet lid opening / closing drive is provided. The surface 255r of the device 255 and the surface 251r of the toilet seat opening / closing drive device 251 are oriented in the lateral direction. FIG. 17 shows a state in which the toilet lid 21 is rotated upward (in the direction of the arrow Y1) and opened (stands up) while the integrated toilet seat 22 is maintained in a closed state. According to the form shown in FIG. 17, since the integrated toilet seat 22 is closed, both the toilet lid opening / closing drive device 255 and the toilet seat opening / closing drive device 251 provided in the integrated toilet seat 22 are in the normal mounting position. The surface 255r of the toilet lid opening / closing drive device 255 and the surface 251r of the toilet seat opening / closing drive device 251 are oriented in the lateral direction. FIG. 18 shows a state in which the toilet seat 22 together with the toilet lid 21 is rotated upward (in the direction of arrow Y1) and opened. According to the form shown in FIG. 18, the toilet seat opening / closing drive device 251 is driven to rotate the integrated toilet seat 22 by approximately 90 to 110 degrees to be in an upright state (open state). Not only the toilet seat opening / closing drive device 251 disposed but also the toilet lid opening / closing drive device 255 rotates with the rotation of the integrally constructed toilet seat 22 in the arrow Y1 direction, and the orientation of the toilet lid opening / closing drive device 255 changes (almost 90 to 90). 110 degrees).

  According to the present embodiment, the axis that is the rotation center of the toilet seat 22, that is, the output shaft 252 and the support shaft 259, the pivot shaft 229 that is the rotation center of the toilet lid 21, and the toilet lid output shaft 256 are the same axis. It is set on the center or substantially on the same axis. Therefore, both the toilet seat 22 and the toilet lid 21 are set so as to rotate on the same axis or substantially around the same axis. For this reason, even when the integral toilet seat 22 is pivotally opened and closed, the rotation locus of the toilet lid 21 and the rotation locus of the integral toilet seat 2 can be made into a similar turning arc, and the turning space can be made compact. The integrated toilet seat 22 and the toilet lid 21 rotate on the same axis or substantially around the same axis, which is advantageous for installation in a narrow toilet room. Therefore, excessive distortion is prevented from being applied to the toilet lid 21 when the integrally constructed toilet seat 22 is opened and closed.

  When the toilet lid opening / closing drive device 255 is turned on in the opening direction from the state where both the toilet lid 21 and the integral toilet seat 22 shown in FIG. 16 are closed, the toilet lid 21 is moved upward (in the direction of arrow Y1) as shown in FIG. ) And can be opened. Further, by turning on the toilet seat opening / closing drive device 251 in the opening direction, as shown in FIG. 18, the toilet seat 22 is rotated upward by about 90 to 110 degrees to be in an open state (standup state). And / or the back surface of the main body 222 can be cleaned.

  By the way, as shown in FIGS. 17 and 18, when the integrally constructed toilet seat 22 is pivotally opened upward (in the direction of the arrow Y <b> 1), the toilet lid opening / closing drive device 255 held inside the integrally constructed toilet seat 22 is also changed to the toilet lid. The output shaft 256 and the output shaft 256 are simultaneously rotated at the same angle in the same direction. This is because the toilet lid opening / closing drive device 255 is disposed in the integrally constructed toilet seat 22. In this case, the toilet lid 21 in the standing position may further open excessively in the arrow Y3 direction (see FIG. 18). Therefore, when the toilet seat 22 that is closed is pivotally opened with the toilet lid 21 pivoted upward (standing) upward, it is fixed to the toilet lid 21 when the toilet lid opening / closing drive device 255 is off. The toilet lid output shaft 256 is configured to be freely rotatable with respect to the toilet lid opening / closing drive device 255. At this time, the toilet lid 21 is prevented from being excessively opened in the opening direction (in the direction of the arrow Y3 shown in FIG. 18) along with the operation of the integrally constructed toilet seat 22 in the opening direction. In this case, as shown in FIG. 10, the locking recess 313 a formed on the back surface of the locking portion 312 of the fixing portion 31 and the toilet lid protrusion 213 d are engaged with each other in a detachable manner. Thereby, the standing state of the integral toilet seat 22 is maintained. Accordingly, the locking recess 313a and the toilet lid protrusion 213d can function as a toilet lid opening maintaining means having a mechanical structure.

  Next, when the toilet lid 21 and the integrally constructed toilet seat 22 are opened in an upright state (see FIG. 18) and only the integral toilet seat 22 is to be rotated and closed in the arrow Y2 direction, the toilet seat opening / closing drive device 251 is moved. By turning on in the closing direction, the integrally constructed toilet seat 22 is pivotally closed downward, that is, in the direction of the arrow Y2. Also in this case, when the toilet lid opening / closing drive device 255 is turned off, the toilet lid opening / closing drive device 255 and the toilet lid output shaft 256 can freely rotate when the toilet seat 22 is rotated and closed. The engagement state between the locking recess 313a formed on the back surface of the locking portion 312 and the toilet lid projection 213d is favorably continued. Therefore, even if the toilet seat opening / closing drive device 251 is driven in the closing direction, the standing state of the integrally constructed toilet seat 22 is maintained.

  When closing the standing toilet lid 21, the toilet lid opening / closing drive device 255 is turned on in the closing direction, and the toilet lid output shaft 256 of the toilet seat 22 is driven in the closing direction. As a result, the engagement between the locking recess 313a and the toilet lid protrusion 213d is forcibly released due to mutual elastic deformation, and the toilet lid 21 can be pivotally closed in the direction of arrow Y2.

  19 and 20 show a second embodiment. Embodiment 2 of the present invention will be described below. The second embodiment has basically the same configuration as that of the first embodiment, and has the same function and effect. The second embodiment applies mutatis mutandis to FIGS. 1 to 18 according to the first embodiment. A common code | symbol is attached | subjected to a common site | part. Hereinafter, a description will be given centering on portions different from the first embodiment. As shown in FIG. 19, slide guide portions 319 a and 319 b are formed on the left and right sides of the fixed base 311 of the fixed portion 31. The slide guide portions 319a and 319b are extended along the front-rear direction of the integrally constructed toilet seat 22 (the directions of arrows X1 and X2 shown in FIG. 1). These slide guide portions 319a and 319b can be moved by operating an engagement / removal mechanism (not shown). The fitting portion 240 a formed on the integrally constructed toilet seat 22 has a slide portion 401. The fitting portion 240 b has a slide portion 402. The slide portions 401 and 402 are extended along the front-rear direction of the integrally constructed toilet seat 22 (the directions of arrows X1 and X2 shown in FIG. 1).

When the integrated toilet seat 22 is attached to the fixed portion 31, the integrated toilet seat 22 is moved in the horizontal direction toward the rear (in the direction of the arrow X2) while the integrated toilet seat 22 is positioned in front of the toilet bowl 1. At this time, the integrated toilet seat 22 is pushed backward (in the direction of the arrow X2) to slide the slide portions 401 and 402 of the integrated toilet seat 22 along the slide guide portions 319a and 319b of the fixed base 311. It is preferable to provide an unlocking selection mechanism for detachably engaging the slide portions 401 and 402 of the integrated toilet seat 22 with the fixed base 311 when the integrated toilet seat 22 is slid to a certain position. .

  When the integrated toilet seat 22 is moved or removed with respect to the toilet 1 during cleaning or the like, the integrated toilet seat 22 is slid along the horizontal direction in the reverse direction, that is, forward (in the direction of the arrow X1). As a result, the slide portions 401 and 402 of the toilet seat 22 are slid along the slide guide portions 319a and 319b of the fixed base 311. In this way, since the integrated toilet seat 22 moves relative to the toilet 1, the back surface of the integrated toilet seat 22 in addition to the toilet 1 can be easily cleaned.
