Embodiment

[0038] Below, according to Figure 1~4 The chain guide 100 according to the first embodiment of the present invention will be described.

[0039] Such as figure 1 As shown, the chain guide 100 according to the first embodiment of the present invention is installed and applied to the timing system installed in the engine room, and slides and guides the chain CH moving between the sprockets S1 to 3 to properly hold the chain. tension. Specifically, as figure 1As shown, the chain guide 100 guides the chain CH that is engaged and rotated between the sprockets S1-3 provided on the crankshaft and the camshaft respectively, and is pressed toward the chain CH by the tensioner T while stabilizing the movement of the chain CH. The tension of the chain CH is maintained appropriately. Furthermore, in the present embodiment, although the chain guide 100 is configured as a swing guide that is pivotably supported in the engine compartment, the chain guide 100 may be configured such as ...

Abstract

The invention provides a chain guide. The size increase of a guide body is prevented while the rigidity of the guide body for the bending or twisting is improved. Specifically, the invention provides a chain guide (100) comprising a guide block (110) and the guide body (120). The guide body (120) comprises a guide block support part (121) used for supporting the guide block (110), a bottom (122) which is arranged to be separate from the guide block support part (121) in the guide height direction of the chain guide (100), and support walls connecting the guide block support part (121) and the bottom (122). Each support wall (123) comprises wall portions (123a) which extend in the guide height direction and connect the guide block support part (121) and the bottom (122). The wall portions (123a) are formed at least two positions separated in the guide width direction of the chain guide (100).

Description

technical field [0001] The invention relates to a chain guide, which comprises: a guide block, used for slidingly guiding a moving chain; and a guide body, supporting the guide block along the moving direction of the chain. Background technique [0002] Conventionally, the following chain guide is known (for example, refer to Patent Document 1), which is installed in a timing system in an automobile engine room (engineroom), slides and guides a chain moving between sprockets, and appropriately maintains the tension of the chain. [0003] here, Figure 14 An example of a conventional chain guide 500 is shown. The chain guide 500 includes: a guide block 510 for slidingly guiding the moving chain; and a guide body 520 supporting the guide block 510 along the moving direction of the chain. The guide body 520 has: a guide block support portion 521 disposed on the guide block 510 side; a bottom portion 522 disposed apart from the guide block support portion 521 in the guide heigh...
