Engine starting device

Abstract

Engine starting devices in the prior art have the problem of deterioration of the starting handle operability because the starting handle is easy to detach the starting shaft to the opposite surface during a reverse running and the cam pin is difficult to stably snapped to the cam of the starting shaft during a starting operation. The engine starting device (2) has a starting handle (21) inserted into a starting shaft (23); a cam pin (211) disposed on the starting handle (21) is snapped to a pair of starting shaft cams (233, 233) disposed in the starting shaft (23); the engine (1) is started by the running operation of the starting handle (21); and the engine starting device (2) has a reversion release device (22) for the release of the starting handle (21) from the starting shaft (23) when the starting shaft (23) runs in reverse. On each starting shaft cam (233), an embedding part (233A) is disposed for the embedment with the cam pin (211), and an inclined part (233B) is disposed at the near front of the embedding part (233A) with a specified angle (theta 1) of the axially inclination of the inclined part (233B) relative to the starting shaft (23).

Description

technical field [0001] The present invention relates to an engine starting device for starting an engine by rotating a starter handle (hereinafter also referred to as "starting operation"). Background technique [0002] An engine starting device that starts an engine by a cranking operation of a starter handle has been known (for example, refer to Patent Document 1). As such an engine starting device, there is a device in which a starter handle is inserted into a starter shaft interlocked with the crankshaft, and a cam pin provided on the starter handle is cam-engaged with a starter shaft cam provided on the starter shaft. The cranking operation of the starter handle starts the engine. [0003] In addition, it is well known that such an engine starting device is provided with a reverse rotation release device. [0004] The reverse release device releases the starter handle from the starter shaft (makes the starter handle disengage from the starter shaft) when the starter s...

AI Technical Summary

Problems solved by technology

[0008] However, in the prior art engine starting device, the starter handle is easily disengaged from the starter shaft when the reverse rotation is reversed, and the cam pin and the starter shaft cam are difficult to engage stably during the starting operation. As a result, there is a problem of poor operability of the starter handle. class questions
