Abstract: A balancer of an engine includes a rod and a balancer piston. A first end portion of the rod includes a joining portion which is arranged to be joined to a crankshaft of the engine at a position that is eccentric relative to a rotation axis of the crankshaft. A second end portion of the rod is arranged to reciprocate inside a cylinder according to a rotation of the crankshaft. The balancer piston is fixed to the second end portion of the rod. The balancer piston is arranged to reciprocate inside the cylinder, while rocking between a contact state in which the balancer piston is in contact with an inner wall surface of the cylinder and a non-contact state in which the balancer piston is separated from the inner wall surface. The balancer piston includes a cylindrical outer peripheral portion that is curved so as to swell toward the inner wall surface.

Abstract: A main wall part is provided so as to surround an integrated circuit part. A sub-wall part which is in “L” shape is provided between each corner of the main wall part and the integrated circuit part. Therefore, even if the stress is concentrated due to heat treatment or the like, the stress is dispersed to the main wall part and the sub-wall part, and hence peeling between layers and a crack are unlikely to occur, as compared with the conventional art. Further, even if the crack and the like occur at the corner, moisture from the outside hardly reaches the integrated circuit part when the main wall part and the sub-wall part are coupled to each other. For this reason, it is possible to ensure an extremely high moisture resistance.
