That is, the thermal diffusion sheet 133 and the fixed sheet 134 sandwich the spacer 132 at a position different from the linear heating element 131 and the linear heating element 131.
Thereby, peeling of the spacer 132 from the thermal diffusion sheet 133 is suppressed and the spacer 132 is positioned.

The height Hs of the spacer 132 is larger than the thickness Hh of the linear heating element 131, and the width Ws of the spacer 132 is larger than the width W of the load support portion 143.
Thereby, even if there is some assembling error, the spacer 132 and the load support portion 143 face each other.

  FIG. 4 is a top view showing an arrangement relationship between the linear heating element 131 and the spacer 132 by removing the seating member 110, the heat diffusion sheet 133, and the fixing sheet 134 in the region D of FIG.

In the first embodiment, two spacers 132 are laid along the circumferential direction of the heating toilet seat 100, and the toilet seat heating means 120 is divided into three regions.
In each region, the linear heating element 131 is repeatedly folded and laid in the inner and outer directions.
Thereby, since the dispersion | variation in the heating area | region of each area | region is suppressed, the dispersion | variation in the heating by a user's seating position can be reduced.

  Next, a state in which the seat 111 is bent by the load P applied to the seat 111 due to the user's seating, and the toilet seat heating means 120 and the support 140 are in contact with each other will be described.

  FIG. 5 is an enlarged view of the main part of FIG. 2 in a state where the seat 111 is bent by the load P applied to the seat 111 due to the user's seating and the like, and the toilet seat heating means 120 and the support 140 are in contact.

  When the seating portion 111 is bent due to the load P applied to the seating portion 111 due to the user's seating or the like, the spacer 132 abuts against the load support portion 143 via the fixed sheet 134.

  That is, since the heating toilet seat 100 includes the support 140 having the load support portion 143 that supports the seating member 110 via the toilet seat heating means 120, the seat portion 111 is bent and seated by the load P applied to the seat portion 111. The load support part 143 supports the load P applied to the seating part 111 when the member 110 contacts the support body 140 via the toilet seat heating means 120.

  That is, since the seat member 110, the toilet seat heating means 130, the support 140, and the bottom wall member 120 are in contact with each other, the load P applied to the seat portion 111 is received as the heated toilet seat 100. The load strength can be increased.

In FIG. 3, the distance ds between the spacer 132 and the load support portion 143 in the direction in which the seating member 110 bends toward the bottom wall member 120 is smaller than the distance dh between the linear heating element 131 and the load support portion 143. .
Thus, as shown in FIG. 5, when the seating portion 111 is bent by the load P to the seating portion 111, the load support portion 143 comes into contact with the spacer 132, and the load support portion 143 comes into contact with the linear heating element 131. Suppress.

(First modification of the first embodiment)
Subsequently, a first modification of the first embodiment will be described.
In the first modified example, the laying positions in the top view of the spacer 132 and the linear heating element 131 are changed.
FIG. 6 is a top view showing an arrangement relationship between the linear heating element 131 and the spacer 132 by removing the seating member 110, the heat diffusion sheet 133, and the fixing sheet 134 in the first modification of the first embodiment of the present invention. It is.

  The heating toilet seat 100 of the present embodiment thus obtained has a load support portion 143 that supports the seating member 110 via the toilet seat heating means 130, and is formed between the seating member 110 and the bottom wall member 120. Since the support body 140 in the hollow space V is provided, not only can the strength of the heating toilet seat 100 be increased, but also the spacer 132 and the load support portion in the direction in which the seating member 110 bends toward the bottom wall member 120. Since the distance ds to the linear heating element 131 is smaller than the distance dh between the linear heating element 131 and the load support part 143, the linear heating element 131 due to the contact of the support 140 including the load support part 143 with the linear heating element 131 is provided. Can be suppressed.

  Further, since the height Hs of the spacer 132 is larger than the thickness Hh of the linear heating element 131 and the width Ws of the spacer 132 is larger than the width W of the load support portion 143, the load support portion 143 is provided even if there is an assembly error. The disconnection of the linear heating element 131 due to the contact of the support 140 with the linear heating element 131 can be reliably suppressed.

  Further, since the heat diffusion sheet 133 and the fixing sheet 134 sandwich the linear heating element 131 and the spacer 132, disconnection of the linear heating element 131 can be reliably suppressed.
