間にパワートランジスタを配置したものである。The power transistor 6 generates heat by the operation of the ignition device, and largely depends on the energization time and the primary inductance and primary resistance of the ignition coil. Further, in an ignition device using a current limiting circuit of a base current drawing type of a power transistor, heat generation further increases. In the present invention, in order to reduce the influence of this heat generation, the heat radiation is improved by the fastening position of the ignition device. The arrangement of the power transistor is located between the bushes of 4b and 4c, and the heat radiation is improved by tightening 4b and 4c. 4a and 4b
Can be dissipated from the portion 4b even when tightened. That is, the power transistors are arranged in a range where the power transistors 4a, 4b, and 4c are connected by a straight line, so that heat dissipation is improved. FIG. 3 shows an application example in which a power transistor is arranged between bushes 4a and 4b.
