Embodiment Construction

[0067] Hereinafter, modes for implementing the present invention will be described based on the drawings. In addition, set figure 1 The direction indicated by the arrow F is the front of the engine 1, the direction indicated by the arrow U is the top of the engine 1, figure 2 The direction indicated by the arrow L is the left side of the engine 1, and the positions and directions of the above-mentioned components will be described below.

[0068] First, by figure 1 and figure 2 The overall configuration of the engine 1 provided with the engine starting device 2 according to the first embodiment of the present invention will be described.

[0069] figure 1 The illustrated engine 1 is a so-called transverse water-cooled engine, which is started by manual operation of the engine starter 2 (rotary operation of the starter handle 21 ). In the engine 1 , a cylinder head 15 is provided on the front side of the cylinder block 10 . Above the cylinder head 15, an air filter 16 a...

Abstract

The invention provides an engine starting device which can easily relieve a handle body from a starting shaft under the situation that the staring shaft conducts a counter rotation. An engine starting device (2) comprises a starting handle (21) and a counter-rotating stop device (22). The counter-rotating stop device (22) comprises a counter-rotating detection mechanism and a first one-way clutch(222D) which can idle along the starting rotation direction and cannot idle along the counter-rotating direction. A counter-rotating relieving mechanism is disposed between an installing shaft (212) and a handle body (213), and is provided with a second one-way clutch (223) which cannot idle along the starting rotation direction and can idle along the counter-rotating direction. The second one-way clutch (223) transmits a rotation force of the handle body (213) to the installing shaft (212) under the situation that the handle body (213) rotates along the starting rotation direction. On the other hand, the second one-way clutch (223) cuts off the rotation force transmitted from the installing shaft (212) to the handle body (213) under the situation that the starting shaft (23) conducts a counter rotation.

Description

technical field [0001] The present invention relates to an engine starting device, which includes: a starting shaft having a starting shaft mounted on an engine; When the rotation direction is reversed relative to the starting shaft, the reverse rotation stopping device of the handle main body that is reversed in conjunction with the starting shaft is stopped. Background technique [0002] Conventionally, an engine starting device provided with a reverse rotation stop device is known (for example, refer to Patent Document 1). The reverse rotation stop device is to stop the reverse rotation of the starting shaft in conjunction with the starting shaft when the starting shaft is reversed, specifically, when the engine fails to start and the starting shaft reverses due to the reaction of the compression force in the cylinder. The device of the handle body. In the engine starting device described in Patent Document 1, a notch on the starter handle side is engaged with a pin on ...
