Abstract: A chain guide is provided which has a simple structure and improved durability, and which enables reduction in weight and in material cost, and moreover which does not inhibit smooth flow of resin inside a metal mold, and with which dimension errors, contour errors, internal distortion, defects and the like are reduced and concentration of internal stresses or repeatedly applied bending stresses can be prevented. A reinforcing rib of a body part includes a lateral rib that has an independent zone not connected to other parts of the reinforcing rib over a length of 20% or more of a distance between support portions at two locations of the rib. The independent zone is provided on a side further away from a guide surface than a midpoint of the height of the support wall.

Abstract: A tensioner with a simple structure is provided, which is capable of keeping oil pressure in a first high oil-pressure chamber stable and holding a chain favorably. The tensioner includes a plunger, a housing, a check valve, an inner sleeve, and a biasing member. In the housing, a second high oil-pressure chamber and a unit setting part are formed. In the unit setting part, a relief valve unit is set. A gap between an inner circumferential surface of a plunger hole and an outer circumferential surface of the inner sleeve functions as part of an oil flow passage that connects the first high oil-pressure chamber and the second high oil-pressure chamber.

Abstract: Provided is a chain guide that enables a reduction in size with a simple structure, without lowering the strength of the chain guide. The base member 30 includes a side wall rib 32 or 33 extending upward higher than a shoe support surface 31 at at least one of both side edges 31a and 31b in a guide width direction. The guide shoe 20 includes, at at least one of both side edges 20a and 20b in the guide width direction, an upstream lip 22, a downstream lip 23, and a shoe widthwise recess 24 formed between the upstream lip 22 and the downstream lip 23 by inwardly recessing the side edge 20a or 20b of the guide shoe 20 in the guide width direction. The side wall rib 32 or 33 is located inside the shoe widthwise recess 24.

Abstract: Provided is a tensioner in which the durability of the tensioner body is increased, the tensioner body is reduced in weight, and the arrangement space is reduced. A tensioner 100 includes a tensioner body 110, a plunger 120, and a ratchet 130. The tensioner body 110 has a hole outer circumferential wall 112 and a pair of pin support walls 116, 117. The hole outer circumferential wall 112 has a pair of outer circumferential wall portions 113, 114 crossing a virtual line L extending in the pin longitudinal direction through the center of the plunger housing hole 111. At least one of the outer side surfaces of the pair of pin support walls 116, 117 is formed on the inner side, in the pin longitudinal direction, of the outer side surface of one of the outer circumferential wall portions 113, 114.
