Abstract PROBLEM TO BE SOLVED: To prevent or suppress intrusion of a thermal conductive material to the mating side between a gear housing and a housing cover.SOLUTION: In a motor with a speed reducer 10, a worm gear mechanism 22 and a circuit board 30 on which a power system element 82 is mounted are housed in a housing 30. A heat radiation block 40 formed in the gear housing 32 is adjacent to a block adjacent portion 74A as a part of the mating surface 74 between a gear housing 32 and a plate cover 70. The heat radiation block 40 is in contact with the lower surface 80A of a circuit board 80 via a thermally conductive synthetic resin material 88 having viscosity. The inside of the housing 30 is partitioned into a gear housing chamber 35 and a substrate housing chamber 37 by a cover body 91 provided to the inner cover 90. A frame portion 92 extending from the cover body 91 is interposed between the thermally conductive synthetic resin 88 and the block adjacent portion 74A.SELECTED DRAWING: Figure 3 【課題】ギヤハウジングとハウジングカバーとの合わせ目側に熱伝導材が食み出すことを防止又は抑制する。【解決手段】減速機付モータ10では、ウォームギヤ機構22と、パワー系素子82が実装された回路基板30とが、ハウジング30内に収容されている。そして、ギヤハウジング32に形成された放熱ブロック40が、ギヤハウジング32とプレートカバー70との合わせ目74の一部であるブロック隣接部74Aに隣接している。この放熱ブロック40は、粘性を有する熱伝導性合成樹脂材88を介して回路基板80の下面80Aに接触されている。また、ハウジング30内は、インナカバー90に設けられたカバー本体91によって歯車収容室35と基板収容室37とに仕切られている。そして、カバー本体91から延出された枠部92が、熱伝導性合成樹脂88とブロック隣接部74Aとの間に介在している。【選択図】図3
