A ground-fixing system for a tire characteristics sensor housing (10) comprises: a fixing plate (1) comprising a plurality of recesses (2) of a given profile distributed over the surface of the fixing plate; and a plurality of fixing pins (3) of substantially corresponding profile, similarly distributed on a fixing face of said sensor housing (10), the shapes and dimensions of the recesses (2) and of the pins (3) for fixing being provided so as to allow, on the one hand, in a position of insertion of the pins, engagement of the latter in said recesses and, on the other hand, in a locking position of the pins, fixing of the sensor housing (10) on the fixing plate (1).

A one-part male bayonet connector, by means of which at least two components are releasably connectable to one another in a non-destructible manner via an opening, which bayonet connector has a double T-like form in a side view, consisting of a head, a central shaft extending therefrom, and two radial webs extending diametrically from the shaft, which each comprise a fastening means of the bayonet connector facing the head so that, in addition to an interlocking bayonet connection, a frictional connection of the at least two components can be produced between the head and the fastening means of the radial webs.

A hook device makes it easy to return a hook from a raised state to a stored state. This hook device has a holding member and a hook member, the holding member has an integrally formed elastic piece, the hook member has a rotating shaft and a hanger, the outer periphery of the rotating shaft is provided with an arcuately formed rotating surface and a holding surface formed so as to be close to the rotating shaft center, and the elastic piece abuts against the rotating surface of the rotating shaft in a flexural state when the hook member is raised, and abuts against the holding surface of the rotating shaft when the hook member is stored.

A combustion chamber includes a bottom wall having at least one opening, at least one sleeve mounted upstream of the bottom wall and fixed to the bottom wall, a closing ring defining an annular groove with the sleeve and fixed to the sleeve, and at least one air and fuel injection system having an axis, mounted in the opening of the bottom wall. The injection system has an annular flange extending radially with respect to the axis and is mounted in the groove with radial clearance. A baffle is situated downstream of the bottom wall and is fixed to the sleeve and/or to the bottom wall.

An assembly for detachably connecting first and second components includes a fastener that transitions between a locking position and a release position. The fastener comprises a first fastening portion and a second fastening portion. The first fastening portion connects to the first component and the second fastening portion connects to the second component. The first and second fastening portions are disposed opposite each other along an axis of the fastener.

The present invention relates to a cam, comprising a head, a body connected to said head and a leg comprising one or more flat bodies extending perpendicular to said body, where said cam further comprises at least one compressible isolation element located below said head and extending at least partially around said body.

A joined body includes: a first member having a pipe shape; and a second member including a wall portion having a plate shape, and a flange portion having a cylinder shape provided with an insertion hole through which the first member is inserted. In a state where the first member is inserted into the insertion hole of the flange portion of the second member, the first member and the second member are joined with the first member pipe-expanded. A material of the second member is larger than a material of the first member in a spring-back amount.
