In other words, the first support surface F11 is arranged on the side of the second boss 162 with respect to the second support surface F12 in the front-rear direction.

第１規制壁１６４は、左右方向において、第１支持面Ｆ１１とは異なる位置に位置している。詳しくは、第１規制壁１６４は、左右方向において、第１支持面Ｆ１１よりも第１ガラス管１１１から遠い位置に配置されている。これにより、第１定着装置１において、第１規制壁１６４は、左右方向において、第１端子部材１５０の段差部１５４と並んでいる。 The first regulation wall 164 is located at a position different from that of the first support surface F11 in the left-right direction. Specifically, the first regulation wall 164 is arranged at a position farther from the first glass tube 111 than the first support surface F11 in the left-right direction. As a result, in the first fixing device 1, the first regulation wall 164 is aligned with the step portion 154 of the first terminal member 150 in the left-right direction.

Specifically, the first regulation wall 164 is arranged at a position farther from the first glass tube 111 than the center of each boss 161, 162 in the left-right direction.

第１端子部材１５０が第１ボス１６１に嵌合した状態において、第１端子部材１５０の第１端１５４Ｅは、前後方向において、第１ボス１６１と第２ボス１６２との間に配置されている。詳しくは、第１端１５４Ｅは、前後方向において、第１規制壁１６４と第２ボス１６２との間に配置されている。より詳しくは、第１端１５４Ｅは、第１端子部材１５０の第１面Ｆ１と対向する部位において、前後方向で第２ボス１６２の最も近くに位置する。前後方向において、第１端１５４Ｅから第１ボス１６１の中心までの第１距離Ｌ１は、第１端１５４Ｅから第２ボス１６２の中心までの第３距離Ｌ３よりも大きくなっている。 In a state where the first terminal member 150 is fitted to the first boss 161, the first end 154E of the first terminal member 150 is arranged between the first boss 161 and the second boss 162 in the front-rear direction. .. Specifically, the first end 154E is arranged between the first regulation wall 164 and the second boss 162 in the front-rear direction. More specifically, the first end 154E is located closest to the second boss 162 in the front-rear direction at a portion of the first terminal member 150 facing the first surface F1. In the front-rear direction, the first distance L1 from the first end 154E to the center of the first boss 161 is larger than the third distance L3 from the first end 154E to the center of the second boss 162.

図７に示すように、第２端子部材１７０が第１ボス１６１に嵌合した状態において、第２端子部材１７０の第２端１７１Ｅは、前後方向において、第１ボス１６１と第２ボス１６２との間に配置されている。詳しくは、第２端１７１Ｅは、前後方向において、第１ボス１６１と第１規制壁１６４との間に配置されている。より詳しくは、第２端１７１Ｅは、第２端子部材１７０の第１面Ｆ１と対向する部位において、前後方向で第２ボス１６２の最も近くに位置する。前後方向において、第２端１７１Ｅから第１ボス１６１の中心までの第２距離Ｌ２は、前述した第１距離Ｌ１（図６参照）よりも小さくなっている。 As shown in FIG. 7, in a state where the second terminal member 170 is fitted to the first boss 161 and the second end 171E of the second terminal member 170 is in the front-rear direction, the first boss 161 and the second boss 162 It is placed between. Specifically, the second end 171E is arranged between the first boss 161 and the first regulation wall 164 in the front-rear direction. More specifically, the second end 171E is located closest to the second boss 162 in the front-rear direction at a portion of the second terminal member 170 facing the first surface F1. In the front-rear direction, the second distance L2 from the second end 171E to the center of the first boss 161 is smaller than the above-mentioned first distance L1 (see FIG. 6).

ここで、第１端子部材１５０のベース部１５１と第２端子部材１７０のベース部１７１は、同じ構造となっているため、各ベース部１５１，１７１の前後方向の寸法は略同じである。そのため、第１端子部材１５０のベース部１５１の後端である第３端部１５１Ｅは、前後方向において、第２端１７１Ｅの位置と略同じ位置に配置されている。 Here, since the base portion 151 of the first terminal member 150 and the base portion 171 of the second terminal member 170 have the same structure, the dimensions of the base portions 151 and 171 in the front-rear direction are substantially the same. Therefore, the third end portion 151E, which is the rear end of the base portion 151 of the first terminal member 150, is arranged at substantially the same position as the position of the second end 171E in the front-rear direction.

図６および図７に示すように、各ベース部１５１，１７１は、前後方向において、第１規制壁１６４と僅かな間隔を空けて対向している。これにより、接続部１５３，１７３からコネクタＣ１，Ｃ２を抜いた際に、ベース部１５１，１７１が図示時計回りに回動した場合であっても、ベース部１５１，１７１が第１規制壁１６４に当接することで、回動が規制される。 As shown in FIGS. 6 and 7, each base portion 151, 171 faces the first regulation wall 164 with a slight gap in the front-rear direction. As a result, when the connectors C1 and C2 are pulled out from the connection portions 153 and 173, even if the base portions 151 and 171 rotate clockwise as shown in the drawing, the base portions 151 and 171 are attached to the first regulation wall 164. By abutting, rotation is restricted.

図６に示すように、第１端子部材１５０に固定される第１ヒータ１１０の第１右リードピン１１２は、左右方向から見て、第１規制壁１６４と重なっている。言い換えると、第１右リードピン１１２は、左右方向において、第１規制壁１６４と並んでいる。さらに、別の言い方をすると、第１右リードピン１１２は、前後方向および上下方向において、第１規制壁１６４の一部と同じ位置に配置されている。 As shown in FIG. 6, the first right lead pin 112 of the first heater 110 fixed to the first terminal member 150 overlaps with the first regulation wall 164 when viewed from the left-right direction. In other words, the first right lead pin 112 is aligned with the first regulation wall 164 in the left-right direction. Further, in other words, the first right lead pin 112 is arranged at the same position as a part of the first regulation wall 164 in the front-rear direction and the up-down direction.

また、加熱ローラＨＲの中心軸ＣＡも、前後方向および上下方向において、第１規制壁１６４の一部と同じ位置に配置されている。そのため、第１右リードピン１１２は、加熱ローラＨＲの中心軸ＣＡ付近に配置されている。 Further, the central axis CA of the heating roller HR is also arranged at the same position as a part of the first regulation wall 164 in the front-rear direction and the up-down direction. Therefore, the first right lead pin 112 is arranged near the central axis CA of the heating roller HR.

図７に示すように、第２右リードピン１２２は、前後方向において、第１規制壁１６４よりも前側に所定間隔を空けて配置される。詳しくは、第２右リードピン１２２は、前後方向において、第１規制壁１６４と第１ボス１６１との間に位置している。 As shown in FIG. 7, the second right lead pins 122 are arranged at predetermined intervals in the front-rear direction in front of the first regulation wall 164. Specifically, the second right lead pin 122 is located between the first regulation wall 164 and the first boss 161 in the front-rear direction.

第３右リードピン１３２は、前後方向において、第１規制壁１６４よりも後側に前述した所定間隔と略同じ間隔を空けて配置される。そのため、各右リードピン１２２，１３２は、加熱ローラＨＲの中心軸ＣＡに対して、それぞれ所定間隔を空けてバランスよく配置されている。 The third right lead pin 132 is arranged in the front-rear direction on the rear side of the first regulation wall 164 at a distance substantially the same as the predetermined distance described above. Therefore, the right lead pins 122 and 132 are arranged in a well-balanced manner with respect to the central axis CA of the heating roller HR at predetermined intervals.
