When the recessed space formed in the vertical direction of the main body plate 26 with respect to the fixed plate 30 is assembled from the rear to the state shown in FIG. 1B (the locked state where the operating lever 30 is not operated), The straight portions 52L and 52R formed by the concave portions 50 of the main body plate 26 are fitted into the convex portions 61 formed on the fixed plate 30 and come into contact with the straight portions 53L and 53R on the main body plate side, respectively.

  Next, assembly of the main body plate 26 to the fixed plate 30 will be described below with reference to FIG.

  FIG. 6 is an operation explanatory view showing the assembly of the main body plate 26 to the fixed plate 30 in the AA cross section of FIG. (A) shows the state before assembling the main body plate 26 with respect to the fixed plate 30, and (b) shows the state during the assembling of the main body plate 26. Further, (c) shows a state where the assembly of the main body plate 26 is completed.

  The fixed plate 30 is inserted into a first groove portion 34L provided with a first protrusion 26g projecting downward on the main body plate 26 side in the front-rear direction. In this case, the first groove portion 34L is provided with a vertical surface 33b on the insertion side, and has a top portion 36L where the height of the vertical surface 33b is the highest, and a first fixed lock taper surface 37L whose height gradually decreases from the top portion 36L. . Before assembling the main body plate 26 in FIG. 6A, the first protrusion 26 g of the main body plate 26 protrudes into the groove portion of the first groove portion 34 </ b> L, but the first fixed lock taper surface of the fixed plate 30. The first protrusion 26g is not displaced by the first fixed lock taper surface 37L. When the main body plate 26 is pushed backward from the fixed plate 30 from this state, the state shown in FIG. That is, in the middle of inserting the main body plate 26 into the fixed plate 30, the first protrusion 26g of the main body plate 26 is in contact with the first tapered surface 26d by the first fixed lock tapered surface 37L. The first arm 26b is displaced upward by the contact and pushed up to the top 36L. Then, when the main body plate 26 is pushed further backward from this state, the state shown in FIG. In the state shown in FIG. 6C, that is, in the state where the assembly of the main body plate 26 is completed with respect to the fixed plate 30 (locked state), the first protrusion 26g of the main body plate 26 passes the top 36L. The contact between the lower end of the first protrusion 26g and the top 36L of the first fixed lock taper surface 37L is released, and the first protrusion 26g is displaced downward by the restoring force of the resin of the first arm 26b. A first fixed lock taper surface 37L provided behind the first groove portion 34L of the fixed plate 30 shown in FIG. 3 is overcome, and the vertical surface 26h of the first projection 26g and the wall surface 33b of the fixed plate 30 come into contact with each other, thereby It will be in the state locked by fitting to the part 35L.

  In the present embodiment, the first protrusion 26g of the main body plate 26 is configured to fit into the concave portion which is the first fixed lock portion 35L of the fixed plate 30, but the first fixed lock portion 35L is at the upper portion. It may have a protruding portion that protrudes, and the main body plate 26 may have a concave portion and may be fitted and locked.

  FIG. 7 is an operation explanatory diagram in the BB section of FIG. 5 corresponding to the states of FIGS.

  Before explaining the operation of FIG. 7, unlocking of the main body 20 by the operation lever 40 will be described with reference to FIG. 7.

  As shown in FIG. 7A, the main body plate 26 is provided with a first protrusion 26g on the other end of the first free end 71 of the first arm 26b supported on one side from the main body plate 26. A first unlocking taper surface 26h (having a taper shape as shown in FIG. 7A on the operation lever side in the width direction shown in FIG. 5) is provided below the tip of one projection 26g. Further, the first lever taper surface 44a of the operation lever 40 having the same taper angle as that of the first lock release taper surface 26h is located at a position facing the first lock release taper surface 26h. With this configuration, when the operation lever 40 is operated by pressing in the X direction shown in FIG. 5, the first lever tapered surface 44a provided on the operation lever 40 is displaced in the X direction in accordance with the pressing operation of the operation lever 40. . When the first lever taper surface 44a is displaced in the X direction, the first lever taper surface 44a abuts on the first lock release taper surface 26h. When the operation lever 40 is further operated from the contacted state, the first arm 26b is displaced upward, and the first unlocking taper surface 26h is pushed upward by the first lever taper surface 44a. The fitting with the first fixed lock portion 35L shown in FIG. 2 can be released. When the main body portion 20 is pulled forward in a state where the fitting of the first protrusion portion 26g in the first fixed lock portion 35L is released as described above, the first protrusion portion 26g of the fixing plate 30 is moved to the first groove portion 34L. The main body 20 can be removed from the fixed plate 30 by exiting from the front opening.

  In the above-described operation, when the operation force in the X direction of the operation lever 40 is removed from the state where the fitting of the first protrusion 26g in the first fixed lock portion 35L is released, the operation lever 40 moves to the first arm 26b. Due to the restoring force of the first arm 26b, the first lever taper surface slides on the first unlocking taper surface 26h and the operation lever 40 moves in the direction opposite to the operation direction (−X direction). It becomes horizontal by the restoring force and returns to the state shown in FIG.

In the state before assembly of the main body plate 2 6 relative to the fixed plate 30 in FIG. 7 (a), but assembling the main body plate 26 with respect to the fixed plate 30 fixed to the toilet bowl 2 from the front to the rear, in this state the first first collision raised portion 26g provided in the first free end 71 of the first arm 26b is moved in a straight line in the first groove 34L shown in FIG. In this state, the first arm 26b supported by one piece is not pushed upward, and is in a horizontal state where it does not bend in the vertical direction.

  When the main body 20 is operated backward from this state, the state shown in FIG. In the state of FIG. 7B, the first protrusion 26g reaches the first fixed lock taper surface 37L shown in FIG. 2, and the first protrusion 34L is fixed to the top 36L of the first fixed lock taper surface 37L. It is pushed up along the taper surface of the lock taper surface 37L. In this state, the lock has not yet been achieved.

  And if the main-body part 20 is further operated back, it will be in the state shown in FIG.7 (c). In FIG. 7C, the first protrusion 26g rises to the top portion 36L of the first fixed lock taper surface 37L shown in FIG. 2, and thereafter the taper surface disappears, so that the first protrusion 26g is restored by the restoring force of the first arm 26b. By being displaced downward and fitted into the first fixed lock portion 35L located at the rear, the locked state is brought into the locked position shown in FIG.

  Next, an operation (operation) of the warm water washing toilet seat device 1 according to the embodiment of the present invention will be described.

  For attaching the warm water washing toilet seat device 1 to the toilet bowl 2, a dedicated mounting screw is inserted into the mounting holes 33 </ b> L and 33 </ b> R with respect to the assembly part 12 at the rear of the toilet bowl 2, and the fixing plate 30 is fixed. After that, as shown in FIG. 8, the main body plate 26 is assembled to the fixed plate 30. In this case, the guide portions 61L and 62L provided with the flange portions 32L and 32R on both sides of the concave space of the main body plate 26 are provided. , 63L, 61R, 62R, and 63R so as to be guided.

  And if the 1st projection part 26g which protrudes below in the recessed part space of the main body plate 26 slides in the 1st groove part 34L of the fixed plate 30 from the front to the back, the 1st projection part 26g will become the 1st lock taper surface 37L. Abut. In this state, the first arm 26b that supports the first protrusion 26g is not displaced upward and maintains a horizontal state. When the main body 20 is further slid rearward, the free end 71 of the first arm 26b, that is, the first end is gradually moved by sliding the tip of the first protrusion 26g on the taper surface of the first fixed lock taper surface 37L. The tip of one projection 26g is displaced upward by the taper surface of the first fixed lock taper surface 37L.

  When the main body portion 20 is further slid rearward from this state, the first protrusion 26g gets over the first fixed lock taper surface 37L and reaches the first fixed lock portion 35L located behind the first groove portion 34L, At this position, the upward displacement of the first protrusion 26g is released after the top 36L, and the first protrusion 26g is displaced downward by the restoring force of the first arm 26b and is fitted at this position. Therefore, the main body plate 26 is in a locked state where it is locked to the fixed plate 30.

  When unlocking from this locked state, when the operation lever 40 is pressed in the X direction, the first lever tapered surface 44a is displaced from the state shown in FIG. By pushing up the first unlocking taper surface 26h upward, the first protrusion 26g is disengaged from the first fixed lock portion 35L provided behind the first groove portion 34L shown in FIG. Canceled. When the main body plate 26, that is, the main body portion 20 is pulled forward and slid in the unlocked state, the main body plate 26 can be easily and easily detached from the fixed plate 30. In the above description, the C portion in FIG. 5 has a similar structure.

  Here, the operation has been described using the first protrusion 26g as an example, but the second protrusion 27g shown in part C of FIG. 5 also has the same operation and the same effect as described above. I will omit the explanation.

  In this case, in the fixed plate 30, the first groove portion 34L (second groove portion 34R), the first fixed lock taper surface 37L (second fixed lock taper surface 37R), the top portion 36L (top portion 36R), the first fixed lock portion 35L.
