図3および図5(A)に示すように、器具本体20の取付面22には、押え部材40を取り付ける押え部材取付部50が、押え部材40の個数に対応して3カ所設けられている。
図5(A)および(B)に示すように、押え部材取付部50は、押え部材40の第1部材41を収容可能に対向するL字形状の一対のブロック51、51を有する。
一対のブロック51、51の間には隙間が設けられており、くびれ部45および第2部材42が、回路基板211側に突出可能となっている。
As shown in FIG. 3 and FIG. 5A, the attachment surface 22 of the instrument body 20 is provided with three pressing member mounting portions 50 for mounting the pressing member 40 corresponding to the number of the pressing members 40. .
As shown in FIGS. 5A and 5B, the pressing member mounting portion 50 has a pair of L-shaped blocks 51 and 51 that face each other so as to accommodate the first member 41 of the pressing member 40.
A gap is provided between the pair of blocks 51, 51 so that the constricted portion 45 and the second member 42 can protrude toward the circuit board 211.

また、回路基板211と反対側には、ブロック51から一定距離離れてストッパ52が設けられている。
ストッパ52とブロック51との間には、押え部材40の第3部材43が挿入可能な隙間53が設けられている。
このため、隙間53に挿入された第3部材43は、移動(図5(A)中矢印A参照)が規制される。
A stopper 52 is provided on the side opposite to the circuit board 211 at a certain distance from the block 51.
A gap 53 into which the third member 43 of the pressing member 40 can be inserted is provided between the stopper 52 and the block 51.
For this reason, the movement (see arrow A in FIG. 5A) of the third member 43 inserted into the gap 53 is restricted.

従って、回路基板211を器具本体20の取付面22に取り付ける際には、回路基板211を、取付面22の第1の突起27、27および第2の突起28、28の内側に位置決めする。

Since the movement of the third member 43 is restricted by the stopper 52 provided in the instrument main body 20, the movement of the pressing member 40 can be prevented and the circuit board 211 can be securely attached to the instrument main body 20.

また、押え部材40の第2部材42は、第1部材41および第2部材42よりも幅が狭いくびれ部45を介して第1部材41に支持されるので、第2部材42は第1部材41に対してばね性を有する。
これにより、第2部材42によって、回路基板211を適度の押圧力で器具本体20に取り付けることができる。
また、回路基板211に接触する圧力の偏りを無くして、回路基板211の破損を防止できる。
さらに、くびれ部のサイズや形状を変えることにより、回路基板211を押える押圧力を調整することができる。
Further, since the second member 42 of the pressing member 40 is supported by the first member 41 via the first member 41 and the constricted portion 45 narrower than the second member 42, the second member 42 is the first member. 41 has springiness.
Thereby, the circuit board 211 can be attached to the instrument main body 20 by the second member 42 with an appropriate pressing force.
In addition, it is possible to prevent the circuit board 211 from being damaged by eliminating the pressure bias that contacts the circuit board 211.
