Abstract
A starter includes a housing having a water barrier wall, a drive shaft disposed in the housing, and pinion gear having a flange portion. The water barrier wall comes into contact with the flange portion when the starter is in operation. The pinion gear is adapted to engage with a ring gear of an engine, which the starter starts. The pinion gear contacts the drive shaft through a sliding portion. The structure of the starter prevents water, dust, dirt and other contaminants from leaking into the housing via a window in the housing. Thus, the function and operability of the starter is improved.
Claims14
A starter for an engine having a ring gear, comprising:
- an output shaft for slidably holding a pinion engageable with said ring gear of said engine axially;
- a housing having a window portion that rotatably supports one end of said output shaft and enables said pinion to engage with said ring gear when said pinion advances, said housing further having a projection portion that projects to the end of said pinion when said pinion retracts;
- and
- a window shutter having a barrier portion that normally covers said window portion, said barrier portion being moved to open said window portion by an advance movement of said pinion toward said ring gear.
A starter having an armature comprising:
- a housing including a water barrier wall;
- a drive shaft disposed in said housing;
- a pinion gear having a flange portion;
- wherein said flange portion comes into contact with said barrier wall when said armature is rotated;
- wherein said pinion gear is adapted to engage with a ring gear of an engine when said armature is rotated;
- and
- wherein said pinion gear contacts said drive shaft through a sliding portion.
