Abstract
Abstract A starting device comprises a hollow cylindrical driving shaft (34), a rotary output shaft (48) placed contiguous to one end of said driving shaft and extending in alignment therewith, a speed reduction unit (41) for reducing revolution of said driving shaft (34) to transmit power from said driving shaft to said rotary output shaft, and a power transmitting shaft (48a) which is firmly connected in alignment with said rotary output shaft (48) and is passed through said driving shaft (34) so as to be rotatable therein, one end of said power transmitting shaft (48a) extending from the other end of said driving shaft (34).

Claim 1
Independent Claim
116 words
A starting device comprising a driving shaft (34), a rotary output shaft (48) and a speed reduction unit (41) for reducing revolution of said driving shaft (34) to transmit power from said driving shaft to said rotary output shaft (48) characterized in that the rotary output shaft (48) is placed contiguous to one end of said hollow cylindrical driving shaft (34) and extends in alignment therewith, and thata power transmitting shaft (48a) is firmly connected in alignment with said rotary output shaft (48) and is passed through said driving shaft (34) so as to be rotable therein, one end of said power trans- mitting shaft (48a) extending from the other end of said driving shaft (34).
Claim 2
Dependent Claim
116 words
A starting device comprising a driving shaft (34), a rotary output shaft (48) and a speed reduction unit (41) for reducing revolution of said driving shaft (34) to transmit power from said driving shaft to said rotary output shaft (48) characterized in that the rotary output shaft (48) is placed contiguous to one end of said hollow cylindrical driving shaft (34) and extends in alignment therewith, and thata power transmitting shaft (48a) is firmly connected in alignment with said rotary output shaft (48) and is passed through said driving shaft (34) so as to be rotable therein, one end of said power trans- mitting shaft (48a) extending from the other end of said driving shaft (34).
Claim 3
Dependent Claim
28 words
A starting device according to Claim 1, characterized in that said cylindrical driving shaft (34) holds an armature (35) of a d.c. motor (31) on its outer periphery.
Claim 4
Dependent Claim
66 words
A starting device according to Claim 1 or 2, characterized in that a free end of said rotary output shaft (48) is supported by a bearing means (64) fitted to a front bracket (65) and a free end of said power transmitting shaft (48a) is supported by a bearing means (39) fitted to a rear bracket (38) so that they rotate integrally on a coaxial line.
Claim 5
Dependent Claim
45 words
A starting device according to one of Claims 1 to 3, characterized in that sleeve bearings (49,50) are interposed between the inner surface of said driving shaft (34) and the outer periphery of said power transmitting shaft (48a) at both ends of said driving shaft.
Claim 6
Dependent Claim
