ABSTRACT:
In a starter unit with an planetary gear speed reducer, the outer cylindrical surface of a cylindrical portion which is axially protruded from the carrier in the speed reducer, and the inner cylindrical surface of a radially extended wall portion of the clutch outer are engaged with each other in such a manner that they are slidable with each other with a predetermined rotation torque, and the end portion of the cylindrical portion is engaged with an axially extended cut formed in the outer cylindrical surface of the end portion of the clutch inner with a small clearance, whereby the engagement region of the carrier and the clutch outer can be increased in area, thus being able to positively and accurately cut the transmission of power attributing only to impact load.
