Problems solved by technology
Furthermore, due to this collision, there is a problem that the noise of the guide due to the collision noise increases or the degree of wear and fatigue of each engaging portion increases, so there is a problem of durability of each engaging portion and even the guide. The problem of reduced durability
[0010] Furthermore, when there is a gap in the height direction between the engaging portion of the base body and the engaging portion of the guide block, the chain shakes due to tension fluctuations or vibrations, and a part of the guide block is separated from the base in the height direction of the guide. Floating, the guide block may also vibrate
In addition, there is also a problem that the noise of the guide increases due to the vibration of the guide block, and the degree of wear and fatigue of each engaging part increases.

Embodiment
[0055] Below, refer to Figure 1 to Figure 16 Examples of the present invention will be described.
[0056] Figure 1 to Figure 7 It is a figure for explaining the 1st Example of this invention.
[0057] refer to figure 1 , figure 2 It can be seen that in the first embodiment of the present invention, the chain guide (hereinafter referred to as "guide") as a guide for a flexible transmission body that guides the chain 20 as a flexible transmission body along its moving direction ") 100 is as follows, which is used in the winding transmission device of the engine of the machine, and here is provided in the winding transmission device for timing.
[0058] The transmission device has: a jointless chain 20; a sprocket device, which is formed by a plurality of sprockets passed by the chain 20; a guide 100, which constitutes a guide device for sliding contact with the chain 20, and the chain 20 is provided by the sprocket device. The drive sprocket is driven to move; and the ...

Provided is a chain guide that offers improved assembly efficiency by a more easily engageable interlock structure, operates more quietly by reducing noise caused by collision between mating parts and looseness of the shoe, and improves durability by reducing wear and fatigue of the mating parts. A lateral interlock structure formed by hole parts 121 and mating protrusions 161 restricts relative displacement of the base 110 and the shoe 150. An opposite interlock structure formed by a groove part 131 and mating protrusions 171 restricts relative displacement of the base 110 and the shoe 150 in the height direction. The mating protrusions 161 and 171 are elastic mating elements. The lateral interlock structure and the opposite interlock structure are a snap-fit joint in which a meshed state is achieved through elastic deformation of the mating protrusions 161 and 171 that occurs in a moving process during assembly.
Description
technical field [0001] The invention relates to a guide piece for a flexible transmission body, which combines a sliding contact guide block of a moving flexible transmission body and a base body supporting the guide block through an engaging structure. [0002] The guide is, for example, a chain guide with which a chain, which is a flexible transmission body, slides, and is provided, for example, in a timing coil transmission used in an automobile engine. Background technique [0003] Heretofore, guides for flexible transmission bodies are known (for example, refer to Patent Documents 1 and 2). The base body and the guide block are combined by the engaging structure formed by the engaging part of the guide block. The guide block has a moving surface that is slidably contacted by the moving flexible transmission body, and the base body has a support surface that supports the guide block.
